Hello everyone;
I’m using a stereographic projection for my maps, but I’m also using a grid data with xyz2grd.
The grid file seems to be in a Mercator projection and is not matching the -JS I’m using, even when I specify a -JS to the grdimage and grdconour.
Is there a way to grid on that projection?
Thank you for your help

Hi Rede,
The `xyz2grd` command reformats data into a grid but does not change the projection. You can change the projection of the xyz data points with `mapproject` to the `-JS` projection that you want before converting the data to a grid. The grid will have the projection that you used in the output of `mapproject`.

Hi Eric,
Thank you very much for your suggestion, I’ll try with mapproject.
Thank you
