Thanks Jukka for your reply.
I understand it is hard.
In my case, I have a lot of data points making your edge

I do that type of things with GMT’s mask module (-D option)

Aihe: [gdal-dev] Convex hull with holes
How can I algorithmically create a parcel border that accounts for islands or
holes within the parcel based on a list of coordinates?
While GDAL+GEOS has a Convex hull method, it only identifies the outer border.
Has GDAL+GEOS a method that I
How can I algorithmically create a parcel border that accounts for islands
or holes within the parcel based on a list of coordinates?
While GDAL+GEOS has a Convex hull method, it only identifies the outer
border.
Has GDAL+GEOS a method that I can use to detect inner holes as well, such
as in a do
