Yes, the functions in src/generated/libgeos_api.jl
and we generally wrap them in geos_functions.jl
to offer a nicer API. And like you mention for GEOSConcaveHull
that hasn't been done yet. That doesn't mean it cannot be used directly though. Contributions like this are always welcome.
So if you have a GEOS geometry object, you can get its context from get_context(obj)
, and pass both into the low-level function. The geomFromGEOS
function converts the pointer we get back from GEOS into a geometry type.
Similarly GEOSConcaveHullByLength
needs to be wrapped, this came up in #182.
I just came across this library and I'm interested in the concave hull functionality of LibGEOS. Looks like there are some C calls implemented for this but I'm unsure how they can be used as there isn't a function like concavehull as one exists for convexhull.
Can the concave hull functionality be used already or does it need some more work and the functions like
GEOSConcaveHull
are just the preparation step?
