Ptolomeus Ecumene

by | Jun 12, 2012

It was only in the 15th century when global coordinate system revolutionized scientific world.

Ptolomeus’ Ecumene is a reconstruction of Geographia, a compilation of thousands of references to various parts of the old world during second century EC, including coordinates which allowed cartographers to reconstruct Ptolemy’s world view.  Maps, were created centuries later aggregating information and using for the first time longitudinal and latitudinal lines and the specifying of terrestrial locations by celestial observations.

We use Earth Science technology to improve the quality of life in our world, especially the economic livelihood opportunities of the world's most vulnerable populations and the sustainable use of the natural resources of our planet. Our work is divided in six main program areas- Climate Adaptation, Climate Mitigation, Ecosystems, Natural Resources, Poverty & Livelihoods and Climate Services.
