From the homepage:

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.

I followed an announcement about i3Geo 4.7 being available when the line “…an application for the development of interactive web maps,” caught my eye.

Features include:

  • Basic display: fix zoom, zoom by rectangle, panning, etc.
  • Advanced display: locator by attribute, zoom to point, zoom by geographical area, zoom by selection, zoom to layer
  • Integrated display: Wikipedia, GoogleMaps, Panoramio and Confluence
  • Integration with the OpenLayers, GoogleMaps and GoogleEarth APIs
  • Loading of WMS, KML, GeoRSS, shapefile, GPX and CSV layers
  • Management of independent databases
  • Layer catalog management system
  • Management of layers in maps: Change of the layers order, opacity change, title change, filters, thematic classification, legend and symbology changing
  • Analysis tools: buffers, regular grids, points distribution analysis, layer intersection, centroid calculation, etc.
  • Digitalization: vector editing that allows to create new geometries or edit xisting data.
  • Superposition of existing data at the data of the Google Maps and GoogleEarth catalogs.

Unless you want to re-invent mapping software, this could be quite useful for location relevant topic map data.

I first saw this at New final version of i3Geo available: i3Geo 4.7.
