I'm having a problem with the text version of the SRTM3 service. Requests for single points works as exepcted, but the lat/lng list call returns "no data" for all points.
thanks. It is fixed.
We are preparing to support an alternative source for srtm3 data and in the implementation of the switch something went wrong.
The alternative srtm3 from cgiar will have fewer voids:
