Geographical information systems (GIS) are a kind of location intelligence technology that supports systematic collection, integration, analysis and sharing of spatial data. They provide an effective tool for characterising and visualising geographical distributions of recyclable resources or materials dispersed across urban environments in what may be described as “urban mines”. As logistics c...

Some activities of geographical data maintenance and standardization work in GIS infrastructures in Japan are first reviewed. Then, from the viewpoint of geometric and combinatorial algorithmics, applied aspects of GIS are described. Some spatial data mining technique is mentioned first, and then the problem of inferring topological information from digital map and the label placement problem a...

With the implementation of Earth Observation System (EOS), various technologies related to Earth Observation (EO) have been dramatically improved and extensively used. Geographical Information Systems (GIS) has also been developed greatly in recent years. Very few researches, however, have been done to integrate GIS and EO. Through analyzing some problems in the application of existing EOS and ...

Development and use of remediation technologies for contaminated soils and water progresses at a very fast pace and thus a large number of cleanup alternatives emerge. The selection of the most appropriate Remediation technology for the given site must be based on many, usually conflicting, criteria. To successfully apply all these criteria a multicriteria decision support system (DSS) is neede...

How to build an image interpretation expert system and other relevant expert systems within a knowledge-based pictorial information system is an ad hoc theme in geographical information system(GIS) field. It plays an important role in building a synthetic information system and in enhancing the GIS system performance. In this article, we present a forestry regional resource planning sub-system,...

This paper gives an overview of Internet Mapping and discusses its use for Geographical Mediation. Internet Mapping summarizes a variety of tools, ranging from geodata and map servers up to online Geographic Information Systems (GIS). First, a classification is proposed, according to the services offered and to the techniques used. Then, the requirements of Collaborative Spatial Decision-Making...

1 : This paper presents the conceptual design and the related implementation of a bidirectional domain interconnection bridging Supervisory Control and Data Acquisition (SCADA) systems and Geographic Information (GI) systems. Due to the numerous common interests and the fact that both realms, SCADA and GIS, have their own central information, namely time-based sensor data and geographical posit...

While most current Geographical Information Systems (GIS) are 2D GIS, more and more application domains as geology, civil and military engineering, etc, need 3D GIS. The particularities and capabilities of a 3D GIS are outlined in this paper. Although 3D GIS are not much developped, some studies have already been done, especially in order to represent 3D data for geological or architectural app...

Natural crises form a big threat on environment; these crises mean the loss of enterprises and individuals, and therefore losses in the sum total of community development. Management to these crises is required through a crisis management plan to control the crises before, during, and after the event. One of the most needed things to consider during preparing the crisis management plan is prepa...

A major limitation in the use of transportation models is the difficulty of obtaining adequate data for them. Geographical information systems are a means of addressing this need. A geographical information system (GIS) is a “computerized database management system for the capture, storage, retrieval, analysis, and display of spatial (i.e., vocationally defined) data.’” GIST is the adoption and...
