Earth Viewer - GIS for your business model
The Challenge
The visualisation approach was to develop an Earth Viewer derived from Geo-VRML using standard data files from satellite imaging and map data including raster and vector data enabling full 3D flyover and interactivity. The Earth Viewer can now be integrated in third party business models.
The Solution
Raster data for the whole earth globe or detail satellite image is stored in the BSTile File format derived from Geo-VRML. The node GeoSphere dynamically tessellates an earth ellipsoid and applies raster tiles at the level of detail (LOD) needed.
GeoMap node supports the overlay of projected vector data like polylines, markers and text onto the earth. One supported format is the ESRI Shape file format. The native BSMap Format stores vector objects into an on-demand loaded quad tree splitted binary file and allows. BSMap currently supports Markers, Polylines, Text, and Text along Splines primitives.
