<br>
I want to visualize the Grib2-File<br>
EDP_MAX_LUIR_201311130000_f001_l0260.gb2 (see attachment)<br>
and get the error "Cannot contour grid - all undefined values".<br>
<br>
I am using Windows 7 with the following software:<br>
- OpenGrADS 2.0.2 win32<br>
- Strawberry Perl 5.20.1.1 32bit<br>
<br>
My ctl-file is created with the following command:<br>
perl g2ctl -0 EDP_MAX_LUIR_201311130000_f001_l0260.gb2 > EDP_MAX_LUIR_201311130000_f001_l0260.gb2.ctl<br>
<br>
Here, the first strange thing happened: g2ctl generated an ctl-file with the variable-name "var019225hy0_0". As OpenGrADS can't handle this variable name, I renamed the variable to "test". As a result, I got the ctl-file<br>
EDP_MAX_LUIR_201311130000_f001_l0260.gb2.ctl (see attachment)<br>
<br>
Now I used the following command to get the index-file:<br>
gribmap -v -0 -i EDP_MAX_LUIR_201311130000_f001_l0260.gb2.ctl<br>
The index-file is also attached.<br>
<br>
With the command<br>
grads -l -c "open EDP_MAX_LUIR_201311130000_f001_l0260.gb2.ctl"<br>
and<br>
display test<br>
I was able to open the file in OpenGrADS. I can see an empty map, but nothing more.<br>
<br>
I can visualize the Grib2-File from<br>
<a href="http://www.nomad5.ncep.noaa.gov:9090/pub/data/nccf/com/gfs/prod/gdas.20141017/gdas1.t06z.engicegrb.grib2" target="_blank">http://www.nomad5.ncep.noaa.gov:9090/pub/data/nccf/com/gfs/prod/gdas.20141017/gdas1.t06z.engicegrb.grib2</a><br>
with the above commands, but not my own Grib2-File. My problem is also, that I don't know what is in the Grib2-File. It is a file from our customer and it's my task to visualize it. Unfortunately even our customer can't give me a visualisation of the file.<br>
<br>
Hope you can help me.<br>
<br>
Kind regards<br>
