I need to recieve the number of points that .las file has from Python and save it as variable. For now I'm doing it like this:

def execute(self, pipeline):
    pipeline = pdal.Pipeline(json.dumps(pipeline))
    self.points_num += int(pipeline.execute())

def points(self, file):
    pipeline = [
            "type": "filters.info",

However when file is big (above 2Gb) the procedure takes up to 4 minutes. Is there a smarter way to get number of points?

  • Have you tried using the laspy package? Then you can read your LAS file, and then get the number of points with len(your_las_file.read().points)

    Here it is shown that you may use the -info, and after that you can len(dict.items()).
