UM SISTEMA DE INFORMAÇÃO GEOGRÁFICA EM PLATAFORMA WEB BASEADO NO GEOSERVER

Abstract

Geoprocessing assists activities in which it is necessary to visualize georeferenced data. This requires using a Geographic Information System (GIS). The most important free GIS applications are uDig and terraView. However, these applications are available in desktop platform, a fact that restricts the information access and difficults the data sharing. This paper therefore presents the EMAPI, an open source GIS developed in web platform, which combines the features found in major available GIS applications. E-MAPI is based on GeoServer, a free maps server to develop customized Webmapping solutions, and OpenLayers, a JavaScript library used to display maps and other geospatial information in dynamic web pages. Index Terms - geoprocessing, Geoserver, GIS, OpenLayers.
