open LAS files #124

Closed Marchowes closed 5 years ago

Marchowes commented 6 years ago

GDAL cant open LAS files natively, so that means either those types of files need to be converted into a DEM that GDAL can read, or a library needs to be found that can do that natively in python.

This may not be possible to do inside pyProm and might need to be a pre-process task.
