[pdal] Merging buffered tiles

[Michael Smith]

Yes, but pdal helps those that help themselves. You can do it but you have to provide all the info. You’d have a pipeline that would apply a crop filter to each tile and that crop filter would have the geometry that would be the inside buffer for each tile. You’re last writer would merge the tiles together (you can use a merge filter but its no longer required for pdal 1.5+). For pdal 1.6 and 1.7, you’ll want to make sure you use stream mode (default in pdal 1.7) as that will minimize the memory footprint.
