GIS Examples

ESS GIS applications range from global to local, city level, scales. Within any given application, a hierarchy of nested regions and map coverages is supported, with maps of different resolution integrated tranparently, depending on the region choosen. For better performance, large maps can be tiled, and preprocessed in various resolutions: these will be switched transparently according to the zoom and resulting scale factors.
