grdmath confused about geographic coordinates on command line
|Target version:||Candidate for next bugfix release|
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.
