hgridshift for projected CRS #3197

Open yurish opened 2 years ago

yurish commented 2 years ago

There are many CRS that require hgridshift, but the actual grid is in projected coordinates. An example of such grid would be Greece GGRS87 grid and Hungary Vitel grid. As far as I know, hgridshift works only with geodetic coordinates. Is there any possibility to apply grid shift for projected coordinates?
