Hi all, I've noticed that mkgmap cannot process the files that you can download from http://opendem.info/opendemeu_download_4326.html because they are zip files containing a directory that contains the needed file. I've added support for this in r4092 now: http://www.mkgmap.org.uk/websvn/revision.php?repname=mkgmap&rev=4092 BTW: The files contain different readme.txt that explain the source, all seem to say this: The following credit must be displayed when using these data: "Produced using Copernicus data and information funded by the European Union - EU-DEM layers."

Have you tested data from http://opendem.info/opendemeu_download_4326.html ? El 27/01/18 a las 15:56, Peter Danninger escribió:
Some results from my .hgt-tests:
I wanted to find usable .hgt files for my web-application zu add height data to .gpx
http://peter.myds.me/HDS/Tipps_Tricks/GPS/GPXclean/GPXclean.html ==> look at: "Spezialisten-Funktionen per Aufrufparameter" ==> sorry, only German ...
==> The results are in the attachment.
In short form: ----------------------------------------------------- Viewfinderpanoramas Medium Europe 3sec: ==> lots of voids and too low height values.
NASA_USGS 1sec: ==> no voids, but some too low height values. not too bad, but easily correctable by directly adjacent height values. BUT only up to N59 in the north.
Viewfinderpanoramas Northern Europe 1/3 sec: ==> some voids in Island in the overlay row/col, but easily correctable by directly adjacent height values.
To sum up: More then 3100 .hgt files without real problems. As far as available these are 1sec files. Only in the very north 3sec .hgt files.
I'm happy with the NASA_USGS 1sec .hgt files :-)

I have no objective method to compare hgt sources (is there any?)
Well, a method I have already used is to get the number of voids in a hgt file using QGIS.
