I am using a geographic grid, us.nc, as argument to -R, then doing a SDIST calculation. I get this warning:

grdmath -Rus.nc 105W 39N SDIST 100 LE = x.nc
grdmath: GMT: Longitude input data detected and successfully converted but will be considered Cartesian coordinates.
grdmath: GMT: If you need longitudes to be processed as periodic in 360 degrees then you must use -fg.

Adding -fg does not change this, but should be unnecessary since us.nc is a recognized geographic grid and things like 105W should be understood.

  • % Done changed from 0 to 100

That particular warning had a boolean that needed to be set when -fg was used or a geographic grid was read. Works in r13052.
