About the Centre for Research in Air and Space Law

Nicolas Matte, the Centre for Research in Air & Space Law was established with the official approval of the Ministère de l’éducation du Québec on 1 September 1976. The McGill University Centre for Research in Air and Space Law is the principal research and educational outreach arm of McGill’s Institute of Air and Space Law, established in 1951.

The Celestia Motherlode: Earth Surface Maps

Most textures here are based on data from the NASA project Blue Marble, but have been modified in various ways to enhance colors etc. The original Blue Marble data had a resolution of 42K (43200x21600), but the improved dataset "Blue Marble Next Generation" was made available in 2005, offering a resolution of 86400x43200 and better quality in many details. Note that a 64K texture made from the original dataset has less detail than one made from the "Next Generation" dataset. Note that "(pre)shaded" refers to textures which have a static shadow already visible on the surface. Generally this looks better than a flat surface texture, but shadows may appear at the wrong side of a mountain because shadows don't follow changes to the sun's position.
