SRTM Update

Thursday, 16 October, 2014

It’s been a little while since I hoofed over to the SRTM webpage to take a look at what’s going on…. and this time there was some great news. In reverse order and all extremely good:

3. Void-Filled “SRTM Plus” Released (SRTM NASA V3): “SRTM Plus uses SRTM Version 2 (see below) where the radar interferometric method was successful (not void). Most voids are filled with elevation data from the ASTER GDEM2”

2. NASADEM: What’s Next with SRTM: “currently working on a complete reprocessing of the original SRTM radar data in order to produce an improved near-global digital elevation model (DEM) to be called NASADEM.” Due for completion in 2017.

1. U.S. Releases Enhanced Shuttle Land Elevation Data: yes, the full-resolution 30m data is being made available in it’s entirety. Great news!
