i3Geo is an application for the development of interactive web maps. It integrates several open source applications into a single development platform, mainly Mapserver and OpenLayers.  Developed in PHP and Javascript, it has functionalities that allows the user to have better control over the map output, allowing to modify the legend of layers, to apply filters, to perform analysis, etc.

i3Geo is completely customizable and can be tailor to the different users using the interactive map. Furthermore, the spatial data is organized in a catalogue that offers online access services such as WMS, WFS, KML or the download of files.

i3Geo was developed by the Ministry of the Environment of Brazil and it is actually part of the Brazilian Public Software Portal.
