Extended terrain layer
The hillshading layer of www.pistes-nordiques.org is now extended up to 72°North with ASTER data.
The same dataset is used for contour lines, hillshading and elevation profile. It is made of a mix of SRTM data with voids filled from ASTER data. I hope Canadian and Scandinavian cross-country skiers will appreciate! Anchorage
These 2 overlays (contour and hillshade) are intended for solely use on pistes-nordiques.org, except express permission. Feel free to contact me by email, I can provide the hillshade layer as a single sqlite file of 53GB and help you to set up a tile server.
ASTER is a product by METI and NASA.
