Thanks for the correct address for the SRTMS files, http://dds.cr.usgs.gov/srtm/version2_1/SRTM3/.

The heights I took from google maps. Obviously I made a approximate calculation.
In Google maps height above sea level is taken. To make the map in SP took the lowest level as zero and "eyeball" do heights.
I do not rule out using microdem. Surely I must learn to use it better
