Hey,
you can do it using plpython and python gdal binding.
It could be a first step to evaluate if it is fast enough for you.

Hi!
How hard/feasible would it be to implement elevation profile/drape line
functionality
Hey,
I did something akin, I decided then for a 2 step process : find potential
matches, then keep none or the better match.
The problem is: given 2 tables A (old) and B(new), find a mapping between A
and B,
with the following limits: a building could be new, destroyed , same or
changed. (Note
Hi Clifford
just a quick saturday morning thought: One approach is to use a hash function
like SHA256. To get started I’d try something like this:
1. For each footprint get a text representation of the geometry
2. Compute and store the SHA256[1] hash of the text representation
3. Find those
I had considered using addressing data to give each footprint a unique id,
but yours does the same with one less step. i'm going to try Rémi-C
solution as well.
Thanks
