GIS is a system designed to capture, store, manipulate, analyze, manage, and present all types of geospatial data. GIS has been applied to many different application areas for geospatial analysis and decision-making such as climate change, disaster response, banking, retail and E-commerce, political campaigns, insurance, and fraud analysis. Currently, several commercial desktop GIS software systems dominate the geographical information (GI) industry, such as Esri ArcGIS, Hexagon Geospatial Geomedia, MapInfo Professional, Global Mapper, Manifold GIS, GE Smallworld, Bentley Map, Golden Software MapViewer, and Clark Laboratories IDRISI. Recently, many free, open-source GIS packages have been developed such as GRASS GIS, gvGIS, ILWIS, JUMP GIS, MapWindow GIS, QGIS, SAGA GIS, and uDig. The development of the World Wide Web creates a unique environment for developing GIS. Besides many of commercial Internet GIS programs such as Esri’s ArcGIS Online, a number of open-source Web map servers, such as GeoServer, MapGuide Open Source, Mapnik, and MapServer, have been developed to offer better tools for managing geospatial data over the Web. These online GIS programs have freed many users from the need to store large geospatial data sets on their own servers. It is possible to perform basic spatial data analyses and transmit data back to the office by using these online GIS programs.

The system proposed in this paper is an integration of several components. Besides the usual MapServer and PostGIS approaches to build most open-source web mapping systems, other programs, such as R or LaTeX, are included to increase computation capabilities, and the ability to create graphics or to prepare high-quality reports.
