This package adds datum conversions with offset grids to the CoordRefSystems.jl package.
It is developed as a separate package because of its additional dependencies.

] add CoordGridTransforms
To use the conversions defined in CoordGridTransforms.jl, use it together with CoordRefSystems.jl in the same environment:
julia> using CoordRefSystems, CoordGridTransforms
julia> c = LatLon{SAD96}(-15, -45)
GeodeticLatLon{SAD96} coordinates
├─ lat: -15.0°
└─ lon: -45.0°
julia> convert(LatLon{SIRGAS2000}, c)
GeodeticLatLon{SIRGAS2000} coordinates
├─ lat: -15.000451566492272°
└─ lon: -45.00042666174454°
