Recent advances in information technologies have increased the production, collection, and diffusion of geographical data, thus favoring the design and development of geographic information systems (GIS). Nowadays, GIS are emerging as a common information infrastructure that penetrate into more and more aspects of our society. This has given rise to new methodological and data engineering chall...

Geographic information Systems (GIS) square measure an honest tool for group action completely different form of spacial info. Its provides fast analysis and correlation of assorted geographical contexts. This method planned collects the data and integration marine data kind satellite pictures. This method automatic collects the surface location of the target. The system gets all info concernin...

In this chapter we present a package-based component architecture for the specific deployment and maintenance of public sector applications, specifically corporate Geographical Information Systems (GIS). The three-tier architecture defines a group of server-side packages, a kernel and external packages, that are dynamically requested and assembled at execution time according to the needs of ind...

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...

Modern geographical information systems make it possible to integrate information from multiple sources in different forms for querying and analysing information. So the importance of geospatial databases is growing from day to day, and their applications extend beyond the traditional applications of geospatial databases and GIS. One of the most recent challenges is integrating geospatial data ...

Geographical Information Systems (GIS) are routinely used by public and private organisations and enterprises as well as lay persons. It is becoming an infrastructure and a preconditioning web implicitly embedded in our information society. Using a GIS is no longer a specialist endeavor. It is a daily activity of non-specialist, with or without being aware of it. This of courser changes the Wor...

One of the fundamental issues of geographical information science is to design GIS interfaces and functionalities in a way that is easy to understand, teach, and use. Unfortunately, current geographical information systems (including ArcGIS) remains very difficult to use as spatial analysis tools, because they organize and expose functionalities according to GIS data structures and processing a...

This paper gives an overview of the recent progress made in the use and application of geographical information systems (GIS) and remotely sensed (RS) satellite sensor data for the epidemiology and control of schistosomiasis in sub-Saharan Africa. Details are given of the use of GIS to collate, map and analyse available parasitological data. The use of RS data to understand better the broad sca...
