grdview does not correctly handle periodicity at poles
|Status:||In Progress||Start date:||2018-07-24|
When plotting polar projections (-Jp) of the pole regions, grdimage connects the 0° and 360° longitudes correctly if the grid contains geographical data. grdview does not follow this behavior, there is a gap between x=0° and 360°. Enforcing periodicity with -nl+bpx or -nl+bg does not help.
The attached image shows the problem (plus some z-ordering issue). It was created with the attached grid and the following command:
gmt grdview test.grd -JP10c/-90 -Bg10a30p/g10a10p -Ctest.cpt -Jz2 -pz130/30 -P -Rtest.grd -f0x,1y -n+bpx > test.ps
