[pdal] Digitized building footprints

[Stephen V. Mather]

Hi Andrew,

The goal is to use the digitized footprints to filter the point cloud of the known buildings. With the buildings removed, I plan to then feed this in to SMRF to remove the vegetation points as best as possible. Something similar to this:

Thanks,
Best,
Steve

Hi All,

I am processing a dataset for which I have a digitized building footprints. It'd be even cooler if I had vegetation, but beggers != choosers.

In principle, I could use filters.overlay, but this is a massive dataset, so I am curious if it makes more sense to rasterize, tile things up, and use filters.colorization.

Happy to test and report back on what is fastest, but in case someone has a hunch, or an alternative recommended approach, I thought I would ask.

It's not clear to me what you're trying to do. Maybe you could state your goal?
