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

Thanks Jukka for your reply.
Thanks Jukka for your reply.
I understand it is hard.
In my case, I have a lot of data points making your edge case not a problem
for me.
The data points are collected driving over a field with 1 or more sensors.
The result can be something like this:

The red dots are the data p
Hi,
So you have an uncategorized bunch of points and you wish to have an algorithm
that recognizes outer and inner rings automatically? I fear that is not as easy
as it may appear. Have a look at the annexed image with two polygons having the
same vertices. How could an algorithm know which int
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
Hi,
For a controlled test you should have a way to make the server side to fail
when you want so. I am not sure if simply unplugging you network connector
would make GDAL to repeat the requests. Installing your local WMS server and
stopping it while GDAL is working could be another possibility.
