The Gaia GPS elevation lookup service, which is used when marking waypoints, and when planning routes, now includes worldwide coverage, going from 80°S to 80°N. The elevation data previously included some gaps, which could result in incorrect results in some areas, these gaps have now been corrected.
These updates were made possible by Nasa’s recent release of 1 Arc second SRTM digital elevation models, and by the addition of ASTER GDEM elevation models to cover the Arctic and Antarctic regions.
