As far as I tried out: the error occurs for any WMS in any projection, including all the built-in servers. It looks like no other GRASS7 user ever had the same issue, which is surprising. From the error message, I assume that soemthing is going systematically wrong with the numbering of the files in the .tmp directory.

I am currently trying with layer: "WMS Global Mosaic, pan sharpened" from the built-in server list: http://onearth.jpl.nasa.gov/wms.cgi

The result is:

ERROR 4: `/home/peifer/grassdata/wgs84/PERMANENT/.tmp/whitefish/32754.4' does not exist in the file system, and is not recognised as a supported dataset name.

File 32754.4 does indeed not exist. See below.

Hi Hermann,

would be possible to send me the WMS service URL you are trying to connect?

Předmět: Re: [GRASS-user] GRASS7: problems with WMS


    Just to add that I continue trying to load the WMS, without success,
    though. My current error message is:

    ERROR 4: `/home/peifer/grassdata/laea/test/.tmp/whitefish/17189.4' does
    not exist in the file system, and is not recognised as a supported
    dataset name.

    When looking into .tmp/whitefish, I see a series of 17189.* files, but
    obviously not 17189.4:

    [GRASS:test]> ls -l .tmp/whitefish/
    total 1184
    -rw-r--r-- 1 peifer mtr 1144239 Sep 18 19:18 17189.0.ppm
    -rw-r--r-- 1 peifer mtr 9125 Sep 18 19:10 17189.10
    -rw-r--r-- 1 peifer mtr 8903 Sep 18 19:10 17189.11
    -rw-r--r-- 1 peifer mtr 574 Sep 18 19:10 17189.5
    -rw-r--r-- 1 peifer mtr 9125 Sep 18 19:10 17189.6
    -rw-r--r-- 1 peifer mtr 8903 Sep 18 19:10 17189.7
    -rw-r--r-- 1 peifer mtr 574 Sep 18 19:10 17189.8
