in the development of new Atlases for Georama.
The structures catalogued here are freely available for download from the
web. Size information and a download option are presented with each
Each structure is available in two forms:
If you have sufficient bandwidth, you might consider downloading the entire set of Voronoi indexing structures offered

Such files carry the filename extension .vix.
- an ASCII file of cell centerpoint latitude/longitude coordinates,
