http://dl-live.theiet.org/content/conferences/10.1049/cp.2012.0390
We present the results of application high-orbital (GPS/GLONASS) and low-orbital (Parus/TRANSIT) satellite navigation systems to the study of different-scale irregularities in the ionospheric total electron content (TEC), such as troughs, crests of equatorial anomaly, traveling ionospheric disturbances and so on. We also present the results of the comparison of the global ionospheric maps (GIM) of vertical TEC, which are now widely used in ionospheric research, with the results of low- and high-orbital radio tomographic ionospheric imaging and with the data of UV spectral imaging form GUVI instrument (Global Ultraviolet Imager). The data from low-orbital radiotomography systems in Russia (Moscow-Svalbard) and Alaska (Arctic Village-Cordova) were involved in the comparison as well as the data of the IGS (International GNSS Service) network. The comparisons cover the time interval from 2003 to 2008, which includes both geomagnetically quiet and disturbed periods. We also demonstrate the possibilities of GPS/GLONASS TEC studies in connection with solar flares and artificial ionospheric heating. (5 pages)Geographic information analysis - past and trends
http://dl-live.theiet.org/content/conferences/10.1049/cp.2011.0289
Effectively analyzing geographic information has attracted renewed attention in a wide range of fields, especially in urban studies. The specific characteristics of geographic information make the analysis of geographic information rather unique. In this review, we discuss the unique characteristics of geographic information and introduce some classical and new techniques in analyzing geographic information. In particular, we pay specific attention to analyzing spatial heterogeneity that inherently exists in geographic information, specifically regressed relationships using geographic information. The extension of analyzing spatial heterogeneity of geographic information in a temporal context is discussed as well. This review echoes a belief that one of the major tasks of analyzing geographic information is to develop new methods to help understand the ever increasing volume of geographic information better. We hope this review serves as a start for interested scholars to energetically seek better analytical techniques to get more insights of what geographic information can offer.

http://dl-live.theiet.org/content/conferences/10.1049/cp.2011.0300
Statistical analysis of territorial development intensity (TDI) from macroscopic angle has become even more important and urgent. Comparing with any other available satellite data source, the nighttime lights collected by DMSP/OLS have a number of favorable characteristics for depicting the spatial patterns of Constructed surfaces on large scale. The nighttime lightsimagery was projected to two-kilometer equal area grid in an Albers conical equal area projection. Linear regression defined a formula for estimating the TDI base on the brightness of nighttime lights. The method was used to estimate the TDI at provincial scale. The estimation results show that: It is feasible to carry out the large-scale TDI calculation with DMSP/OLS nighttime lights data. This method has the promotion demonstration value for other similar research. (6 pages)The research on countrywide railway operation simulation system
http://dl-live.theiet.org/content/conferences/10.1049/cp.2011.1398
Based on the analysis on Countrywide Railway Operation Simulation System, the logic model which is on the basis of Data Flow Diagram (DFD for short) has been put forward.

http://dl-live.theiet.org/content/conferences/10.1049/cp.2011.1392
With the expansion of urban area, urban bus transit plays an increasing important role in urban transportation. Nowadays, factors for bus route network planning become increasingly complicated with the construction of rail transit in metropolises of China. The object of this research is to optimize bus network in Wuhan using a GIS-based framework to alleviate or solve the problems exposed from current existing bus routes in the city, such as reducing the route overlapping, enlarging the network coverage, and reducing the nonlinear coefficient. This research employs a method for multi-modal transit route design based on stops, which treats certain rail routes as restrictions. Genetic algorithm (GA) is applied to search for optimal combination of candidate routes. With the case of central area in Wuhan, a scenario has been developed for the short-term situation with No.1, 2 and 4 rail routes. A comparison is made between the existing and the optimized results. It has been found that our GIS-based optimization approach may generate more appropriate bus route network for the large city.Novel methods to demarcate urban house submarket - cluster analysis with spatially varying relationships between house value and attributes
http://dl-live.theiet.org/content/conferences/10.1049/cp.2011.0288
In urban house market studies, urban housing market can be divided into a series of submarkets. Usually, submarkets are identified with either geographic locations or housing structural characteristics, or some combination of both. In this study, we propose an alternative to identify urban housing submarkets. Instead of using house characteristics or locations, we use the relationships obtained through a geographically weighted hedonic regression (GWHR) model. In particular, we apply a K-means classification on the coefficients obtained via GWHR to identify different submarkets. Data from the City of Milwaukee are used to test the model and procedure. Comparison of a regular cluster analysis using housing structural and neighborhood socioeconomic information and the proposed procedure is conducted in terms of prediction accuracy. The analytical results suggest that hedonic regression on demarcated submarkets is better than a uniform market, and our proposed method yields more reasonable result than the ones using raw data.

http://dl-live.theiet.org/content/conferences/10.1049/cp.2010.0564
Due to global e-Map on Internet, tourists can easily and precisely find the position that they are interested in. Using one kind of tag-based microchips, a RFID system is usually combined with back-end information systems to sense the tag information with internet-connected readers through wireless transmission. Recently, since the number of travel websites is under unceasing development and increasing, tourists can deeply understand scenic sites before their trips. However, the travel agents capture tourist information, only from the leading tour guides on trip, which is an ineffective monitoring procedure. This research discusses how to combine RFID technology with Google Maps in traveling applications, and provides two-way monitoring procedures with an e-map traveling system. As proposed scheme, RFID tags are attached to tourists using RFID wireless radio frequency identification technology. Four monitoring components are designed to deliver tourists' tag information so that travel agents can automatically track their tours and tourists by remote monitoring information from the mobile and spot-based RFID readers instead of tour guides. The monitoring information of tracked tours and tourists will be represented in internet-based Google Maps. By comparing with the existing traveling websites, this paper discusses advantages and disadvantages of the procedures proposed.Fractal characteristics of the road network in Jiangsu Province
http://dl-live.theiet.org/content/conferences/10.1049/cp.2010.1135
Based on fractal theory, and with the help of GIS software, this paper illustrates our research on the spatial structures and patterns of the road network in both northern and southern Jiangsu province at the year of 1999 and 2009. Hausdorff dimension value and covering depth of the road network have been calculated in both the two regions at the year of 1999 and 2009. The evolution of road networks in Jiangsu Province over the last decade has also been analyzed. The results show that in the same year, no significant differences exist in the fractal dimension and covering depth between the two regions, but for the same region, the difference between the year of 1999 and 2009 is remarkable, which indicates a rapid construction and development of the road network in Jiangsu province over the last decade, and a well maintained regional balance at the same time.Cognitive access to the interleaved channels: Update and next steps

http://dl-live.theiet.org/content/conferences/10.1049/ic.2009.0253
This paper addresses the task of making a mosaic map with moving object information from images gathered by a downward-looking camera on an airborne platform so that the picture of the ground movement can be exploited by higher level analysis. We have previously successfully shown in simulations that the bundle adjustment techniques results in consistent, undistorted maps. In this paper techniques for feature matching between overlapping, but non-sequential, images, where track information is not available, have been developed in order to apply bundle adjustment on loop closure with real data. These techniques are based on geometric and appearance based feature matching. Tracks of moving objects are also placed on the mosaic image using the homographies of in-between frames and performing local bundle adjustment. The algorithms have also been extended to use a graph decomposition technique in order to provide a scalable solution to real scenarios. (5 pages)Research on DEM data coding
http://dl-live.theiet.org/content/conferences/10.1049/cp.2009.1935
According to the characteristics of DEM data, each normal vector of vertex is calculated, quantified and coded based on multi-resolution wavelet-transform coding. Meanwhile, the data is displayed in three dimensions. This paper focuses on the DEM data coding based on wavelet transform, which enable the model to transmit and to display DEM data progressively. The calculation and coding method of vertex normal vector calculate the lighting effects, and produces the light and shadow effect. The method, proposed in the paper, includes Mipmap texture optimization techniques, and can produce desired effect. This method has a wide application prospect in the digital terrain elevation mapping and SOC chip lithography simulation and other fields.Architecture for structural optimization of urban road networks - case study of Beijing City
http://dl-live.theiet.org/content/conferences/10.1049/cp.2009.1609
Road infrastructures are always the topmost prerequisite to balance the supply and demand and reduce the congestions in urban transport, which is essential to support for the sustainable development of a city. This paper is a case study of Beijing, the capital city of China.

http://dl-live.theiet.org/content/conferences/10.1049/cp.2009.1995
In order to meet the demand of real-time transmission of the terrain data and efficient display, based on the different view field of high altitude and surface, firstly, a general(efficient to both surface and high altitude) view field algorithm is proposed. This algorithm promotes the traditional vision clipping algorithm, efficiently determining the visibility of the view field, the LODs of the key nodes and previsible region when position of the vision moves. Pre-scheduling method is used to keep the calculation in order. Then progressive transmission strategy is adopted to transmit the processed data. Finally, the validity of the algorithm is approved by experiment.A realtime large scale terrain visualization algorithm through network
http://dl-live.theiet.org/content/conferences/10.1049/cp.2009.2005
We study the characteristics of massive complex 3D scene data and its remote interactive rendering through networks. Then a new data organization and transfer strategy is proposed. First of all, the server side analysis and partition the 3D scene data source. For each block, an improved SPIHT algorithm is used to code it into compressed data, which is reorganized to form a bit stream for the transmission by networks. The clients adopt a progressive transmission strategy by comprehensive consideration of the needs of the client users, the networks conditions and the data characteristics. Once any length of forehead of a bit-stream is received by the client, it can be added to buffer for 3D scene reconstruction, greatly reducing the time of waiting for display. Then we adopt a LOD scene rendering algorithm based on view-dependent visible region, which reduces the data volume immensely that needs transmission immediately. Simulations results demonstrate that the system is built by our algorithm ensure primely that clients render the scene accurately in real time and users have a good visual experience with low network bandwidth.Monitoring of rail freight wagons in Europe with support of Eureka projects

http://dl-live.theiet.org/content/conferences/10.1049/cp_20080362
QBE was the most popular manner of CBIR systems. But, "Semantic Gap" is an obstacle to make QBE more efficient. The contribution of this paper was that a framework of QBC (query by concept) was proposed to minimize the effect of "semantic gap". Also, a method was proposed to obtain concepts. An attempt was made with landscape images with "blue sky" and "green grass". Experiment data were about 7000 images collected from Corel database and Internet. The experimental results demonstrated the method was feasible, effective and robust.Tools for local critical infrastructure protection: computational support for identifying safety and security interdependencies between local critical infrastructures
http://dl-live.theiet.org/content/conferences/10.1049/cp_20080736
Previous terrorist attacks, infrastructure failures and natural disasters have revealed the problems that states face in preparing for civil contingencies. One aspect of this is that the agencies which typically coordinate the protection of critical infrastructures have a national responsibility. However, the impact of particular failures is often focused at a local or regional level. For example, Hurricane Katrina was most acutely felt in the City of New Orleans (over 350,000 people affected), with concentrations in suburban Jefferson Parish (175,000) and St. Bernard Parish (53,000) and along the Mississippi Coast (54,000). The terrorist attacks of 2001 and the UK floods of 2007 also show how multiple localised contingencies can occur at the same time. National infrastructure protection agencies must, therefore, be prepared to provide simultaneous help to multiple local agencies. It is for this reason that national civil protection bodies provide national guidance but then devolve responsibility for the implementation of contingency plans to a local level. Unfortunately, many of the regional groups who are responsible for infrastructure protection have little or no idea about the detailed inter-relationships that exist between their own local infrastructures. For example, in the UK 'risk registers' enumerate local hazards without considering how, for example, an attack on a gas storage facility might damage power distribution infrastructures. Nor do they consider the knock-on effects that such damage might have upon water pumping and purification systems. This paper introduces a geographic information system that is intended to help identify dependencies between local critical infrastructures. Although we focus on supporting interaction between local and national contingency planning within the United Kingdom, similar problems affect many other nations. The goal is to support the 'joined up' thinking that is often recommended in the aftermath of previous failures. (6 pages)A hybrid clustering and classification technique for soil data mining
http://dl-live.theiet.org/content/conferences/10.1049/ic_20070772
Predictive soil modelling using geostatistical methods is a research concept in modern soil science and soil geography. One of the reasons for this lack of soil spatial data is that conventional soil survey methods are relatively slow, qualitative and expensive. Spatial data sets covering large areas like digital geomorphographical maps, geological, land use, and climate data are available and these geo-datasets contain information about soil formation and resulting hydrologic variables etc which are needed to extract relevant soil information. In this paper we present an efficient hybrid model that was achieved by first clustering the data and then classifying it, and using the spatial conceptual information extracted from the environmental variables. This paper assists in assessment of the status of food production associated with land degradation and estimate indicators of soil nutrient mining by a country and region. The findings and conclusions of this paper result from the monitoring of the nutrient mining of agricultural lands in a country which have a direct implication on policy development. We propose a framework where soil is classified into different types, then a future work could be to predict soil fertility, based on which you can decide upon the fertilizers and suitable crops that could be cultivated with expertise.Understanding mobile spatial interaction in urban environments
http://dl-live.theiet.org/content/conferences/10.1049/cp_20070348
In order to act in urban environments an individual access various types of knowledge, such as memories, spatial strategies and also information from the environment in order to develop plans and make decisions. This paper will investigate the nature of spatial knowledge acquisition by comparing performance in a task where the subjects learnt the environment using spatial assistance; either from a map or from a mobile map. It outlines the early results of an empirical experiment which evaluated subjects spatial knowledge acquisition in a large scale environmental setting for orientation and distance estimation tasks. The initial findings of the experiment highlight the fact that mobile map subjects performed worse in distance estimation tasks than map subjects, and that their errors for complex routes were high. We will conclude by analyzing the results of this experiment in terms of the specific types of knowledge afforded by mobile maps and the implications for spatial learning in urban environments.The satellite positioning and planning system of open-pit mine vehicles and mining equipments

http://dl-live.theiet.org/content/conferences/10.1049/cp_20061702
The time-based or photoelectric switch control methods of streetlight can't respond to the changes of the weather. The strategy of streetlight remote control based on geographic information system (GIS) in bad weather is presented. The light sensors are installed at each streetlight transformer station, remote terminal unit (RTU) detects light level, sends alarm messages to control center when it gets lower in lighting on or higher in lighting off than threshold. Once control center receives an alarm message from RTU, the system selects a rectangle region by the reference of alarmed RTU locations on geographical map and enlarges region by exponential growth. The system queries all RTUs in selected region, switches on/off streetlights by the rate of alarmed RTUs number in all queried RTUs. This control approach can identify abnormal alarm of RTU, switch streetlights on/off in partial region and reduce electrical consumption of streetlights. It can also turn streetlight on in appointed region by sequence and locate the fault RTU or lamp pole by the means of GIS, that avoids voltage fluctuation of power net produced by all lamps on at the same time and improves the efficiency of streetlight maintenance.

http://dl-live.theiet.org/content/conferences/10.1049/cp_20061740
Based on the fuzzy evaluation theory, taking into account the geographic information and the correlated factor which relates to substation locating, This paper establishes the feasible plots layer suitable for substation locating . Taking minimal investment and yearly operating cost as objective function, the number and position of substations, the capacity and number of transformers, and the power supply range of substation, are determined by the PSO optimum algorithm. The position of new particles' in the iterations is produced in the suitable plot in order to make all particles fall in the suitable land scope. This ensures the optimal solution produced by PSO to satisfy the feasibility between geography and economy. The method overcomes the shortcoming which the distribution of initial particles affect the convergence of PSO and ensures the optimal solution's scientific nature and utility about economy and geography at the same time. Finally, the algorithm is tested by a realistic planning project, which shows its efficiency and accurateness.

http://dl-live.theiet.org/content/conferences/10.1049/cp_20061070
Owing to advances of container port logistics in today's globalized economy, the competitive edge of container ports has shifted to information management paradigm for the purpose of cost- and time-efficiency. However, an effective yet systematic information sharing strategy, in terms of information acquisition, processing, communication, storage, display and analysis, has not been well addressed. In order to resolve this impact, a novel logistics information system, i.e. a GIS-based information-sharing infrastructure, is postulated and established based on the closed-loop control modeling. In details, it comprises three interacting modules, namely input module, output module and feedback module. In the input module, the GIS-based logistics information is first acquired and processed, and then stored in a database. Subsequently, the information is analyzed and displayed via the output module. As for the feedback module, the information is consequently fed back to adjust some indices, so as to adapt to the entire system optimization and coordination. On account of sharing information through this infrastructure, an in-depth strategy is developed to integrate data mining and visualization using such as virtual reality (VR) and analysis tool-kits. Finally, a case study on Tianjing container port is used to illustrate and validate this approach. It is accordingly envisaged that the proposed GIS-based information-sharing infrastructure can effectively facilitate and expedite the container port operation process.The establishing of GIS system and its function in city electric power supplying management

http://dl-live.theiet.org/content/conferences/10.1049/cp_20050091
A new approach to speckle reduction with texture preservation is presented termed granulometric shrinkage. The technique is analogous to wavelet shrinkage but with the wavelet transform replaced by a nonlinear multiscale granulometric sieve. The sieve employs area morphology, thus removing any shape bias associated with the use of fixed structuring elements. As the granulometric sieve is by nature edge preserving, the benefits of the new approach include improved edge and texture preservation. Experimental results using a SPOT image corrupted by synthetic speckle show the new approach to have a better speckle reduction capability than conventional wavelet shrinkage, with improved preservation of edges and other high frequency image features.Semi-automatic extraction and vectorisation of multicoloured cartographic objects
http://dl-live.theiet.org/content/conferences/10.1049/cp_20050079
We describe a semi-automatic cartographic image interpretation system in which techniques previously applied to monochrome images are generalised to colour and extended to support digitization of the full range of multi-coloured cartographic objects. A snapping tool eases the selection of seed points, speeding interpretation. Line and area objects are identified automatically and a suitable target representation (skeleton or contour) produced for each. This simplifies interaction as the user does not have to vary his/her behaviour with object type. Multi-coloured objects can be constructed from their components with ease and correction tools such as snapping and undo both save time and decrease error rates.Image primitives: automating image interpretation procedures in topographic map production
http://dl-live.theiet.org/content/conferences/10.1049/cp_20050086
An outline is provided of a research programme at a national mapping agency, that aims to use computer vision tools modelled upon the theories of vision perception to improve the efficiency of the update of topographic maps. Based upon the underlying principles of top-down and bottom-up influences on image interpretation, case studies are presented that illustrate results produced after the application of robust algorithms for extracting low-level `primitive' information from aerial photography. In addition to contributing to research that aims to produce automatic mapping systems, it is intended that algorithms for producing these primitives will form the basis of semi-automated tools that help photogrammetric operators update maps in an increasingly efficient manner. The work presented here is an outline of research programme, upon which the author gratefully acknowledges the contributions of Panja Sai-Ui (2003), Paolo Gamba et al.

http://dl-live.theiet.org/content/conferences/10.1049/ic_20050227
Widespread deployment of location-based services such as pervasive games is often dependent on the availability of cartographic maps and virtual 3D models of architectural urban spaces. Construction of such models is time consuming and labour intensive process. This paper describes an attempt to appropriate geometric data (i.e. satellite availability or line-of-sight) provided by GPS satellite transmissions in a novel way, and use this data to create models of volumetric spaces through pixel-culling. The intention is to develop an application, capable of running on a portable device, capable of sensing the environment around it and creating a 3D model of it on-the-fly in real time as the user explores the wild. Such an application could prove particularly useful component in the development of interactive experiences in urban environments, obviating the need for predefined game spaces and landscapes and allowing for more playful and dynamic electronic representations of the interaction environment. The paper outlines the methods and technology used, describes the challenges overcome so far and presents illustrations of the progress to date in the form of 3D images of South Kensington, London.

http://dl-live.theiet.org/content/conferences/10.1049/cp_20010818
This paper presents the experience of Empresas Publicas de Medellin (EPM) in the implementation of its distribution automation project an integrated SCADA/distribution management system (DMS). It includes some distribution applications, interfaces with existing geographical information (GIS) and customer information (CIS) systems to get the information of the distribution networks and the SCADA itself. For the DMS, the main applications are described together with the experience in the implantation of the GIS interface. For SCADA the emphasis of this document is in the experience related with the extensive use of intelligent electronic devices (IEDs) to get the real time information of the distribution feeders, the use of a trunking system for the exchange of information with automated distribution network points and the integration experience of several manufacturers with different communication protocols needed to comply with the project requirements. The main benefits obtained as well as the risks taken and the main solutions adopted are illustrated for this ambitious project. All project phases are operational and have provided EPM and its users important benefits, and thus have provided for a better corporate image. (6 pages)Rural electrication planning software (LAPER)
http://dl-live.theiet.org/content/conferences/10.1049/cp_20010884
Today, 40% of the world population need rural electrication (RE). The World Bank and other donors for RE-projects need a clear assessment of the viability and sustainability of the proposed electricity generation facility. Electricite de France (EDF) and the French Agency for Environment and Energy Management (ADEME) have developed LAPER, a planning software package using a GIS-based method for the electrication of vast regions. This program determines a masterplan using geographical data enhanced by socio-economic inquiries. After choosing the optimal means of electrication (MV-network, PV-panels, gensets, micro-wind generators or micro-hydrogenerators) for each village, LAPER calculates an investment plan and an electrication schedule for the region, taking into account political, financial and geographical criteria. The results are stored graphically and by tables in the GIS. (8 pages)Automatic fault management in distribution networks

(6 pages)GIS based distribution simulation and analysis
http://dl-live.theiet.org/content/conferences/10.1049/cp_20010894
Electric utilities are extending the value of their geographic information systems (GIS) implementations in many innovative ways. One area of expansion is the enabling of power distribution analysis from with the GIS or directly from data extracted from the GIS. This paper presents a discussion of the environment leading to GIS based distribution analysis. It also presents required aspects of any embedded or integrated analysis. Finally the four models for GIS based analysis are presented. (5 pages)Sharing data in a modern control centre configuration: architecture and experiences
http://dl-live.theiet.org/content/conferences/10.1049/cp_20010815
In general electrical utilities are facing a challenge to reduce life-cycle cost and improve flexibility in operation and services. To achieve this goal there is the need for computer system integration, spanning different types of data and services dispersed by various business processes. Computer based applications have been growing in complexity and inter-dependence. The challenge is to ensure the system survives the introduction, replacement or removal of any integrated application. Nowadays, component technology is a strong trend in the software industry for tackling these issues. A component may be seen as a software unit, providing functionality and services to others based on two well defined contracts: (1) the open component contract between any component and the component support middleware, and (2) the business specific contract, implemented by events within the open component contract to offer the application or database interface. The open component contract provides the key for achieving a successful system integration with true data sharing. The aim of the presentation is to outline EDP, EDINFOR and EFACEC experience in CORBA and component based architectures within a joint project for the development of a new generation of distribution control centre, as well as to present the foreseen implementation program. The presentation focuses on the use of component technology for data sharing and interfacing between a SCADA/DMS and GIS system, thus allowing the flow combined spatial and operational information to support multiple processes and user profiles on decision making. (5 pages)Approach to a changing industry - answer to the needs of utilities in deregulated markets
http://dl-live.theiet.org/content/conferences/10.1049/cp_20000399
The pace of change in the utilities' industry is rapid and dramatic. As shown in this paper, a vision must therefore address business transformation, technology and process integration and operational excellency not only in core processes but also in support processes. Concentration on core business while going in the direction of IT outsourcing and business process outsourcing needs a consolidated approach to justify the business processes as well as design and implementation of customer specific solutions. A solution of products, systems and services must fill the gap between financial enterprise resource planning systems, customer relationship management systems and the technical IT world with power system control, geographical information systems and maintenance systems.Model-driven line-following in scanned cable diagrams
http://dl-live.theiet.org/content/conferences/10.1049/ic_19990214
The study is concerned with the automated analysis of scanned cable and associated diagrams for entry in the BT GIS system used by their field service engineers. The salient information in these diagrams is currently being extracted manually at great time and expense. The key information required from these diagrams, is the ducting routes (lines) between their joint boxes (solid black squares) and the end points (circles) on their infrastructure network. These features are also present in the cartographic maps of the area and the cable diagrams, and once detected, enables information held on the different diagrams to be linked together. The physical possibility of providing a new line to a property, for example, requires information to be derived from the cartographic map, and the associated ducting and cable diagrams. The work described is concerned with the identification of the ducting routes in the scanned cable diagrams. (6 pages)
