Simple overrides ​

This file contains simple overrides for GEOS, essentially only those functions which have direct counterparts in LG and only require conversion before calling.

Polygon set operations ​

Difference ​

julia
function GO.difference(::GEOS, geom_a, geom_b; target=nothing, calc_extent = false)
    return _wrap(LG.difference(GI.convert(LG, geom_a), GI.convert(LG, geom_b)); crs = GI.crs(geom_a), calc_extent)
end

Union ​

julia
function GO.union(::GEOS, geom_a, geom_b; target=nothing, calc_extent = false)
    return _wrap(LG.union(GI.convert(LG, geom_a), GI.convert(LG, geom_b)); crs = GI.crs(geom_a), calc_extent)
end

Intersection ​

julia
function GO.intersection(::GEOS, geom_a, geom_b; target=nothing, calc_extent = false)
    return _wrap(LG.intersection(GI.convert(LG, geom_a), GI.convert(LG, geom_b)); crs = GI.crs(geom_a), calc_extent)
end

Symmetric difference ​

julia
function GO.symdifference(::GEOS, geom_a, geom_b; target=nothing, calc_extent = false)
    return _wrap(LG.symmetric_difference(GI.convert(LG, geom_a), GI.convert(LG, geom_b)); crs = GI.crs(geom_a), calc_extent)
end

    chull = LG.convexhull(
        LG.MultiPoint(
            collect(
                GO.flatten(
                    x -> GI.convert(LG.Point, x),
