Spaced Out ::

This announcement passed me by and seems to have been missed by quite a few other blogs….. and for those not in the know, SRTM is a global DEM product collected on a space shuttle mission a decade ago. What was perhaps unusual was that TWO different sensors were used to collect the data creating two different products. NASA freely released its data for the world at 90 m resolution, but only 30 m data was available for the US. The DLR sold its data at 25m resolution, high vertical accuracy, but not entire coverage. This latter product is now free and available from EOWEB.
