So the grid is already in UTM hence you cannot apply -Ju again.  You'll =
need to see example 28 for how to mix UTM grid and geo annotations.  =
This may perhaps not be possible through the web interface.  Basically =
you would plot the grid using a linear scale -Jx1:50000 and overlay a =
psbasemap with the -Ju projection.

      <pre wrap="">Seems odd if you can run grdimage on the serve but not grdinfo? I doubt they have disabled some of the programs.  Unless you have a web interface that only allows a few things.  We also don't know what GMT version you are running so it is still pretty unconstrained.  Without info on file area etc I cannot really help.

          <pre wrap="">Your -R is probably wrong.  The trailing "r" means that your area is defined by the lower left (8.5/9) and upper right (46.5/47) corners you specified, but I suspect you instead mean to say

-R8.5/46.5/9/47r

The other selection would requires an enormous image grid and hence the memory message.

(I'm using gmt via a service which runs on a university server. grdinfo doesn't run there).  Is it possible to get the gird information in other ways (e.g.: QGIS)? I tried to install gmt locally, but haven't  succeeded, yet.

Hello,

I want to visualize a slope (format: netCDF) using grdimage.
I get the following error message:
"error 104: execution failed: GMT Fatal Error: grdimage requesting negative n_items (-64887781) - exceeding 32-bit counting?"
My grid file is a 32-bit file. I also tried to process a smaller part of the grid using the -R option.

Has anyone an idea what could help to slove this problem?

Best regards,
Felix
