The current features that OWGIS provides on the generatedWeb GIS sites are: multiple languages, animations, mobile interface, Contextual Query Language (CQL) filtering (http://en.wikipedia.org/wiki/Contextual_Query_Language), identify features, the ability to download data as KML, GeoTIFF or shape files, and the capacity to plot vertical profiles and vertical transects at different locations. Though some of these features are already available in many Web GIS sites, regardless of whether or not they display scientific data or other types of geographic data, OWGIS allows building and maintaining new sites with all these features by simply editing XML files.
