traceAreaLas 1.1

traceAreaLas is a small program in Python 3.11 which traces in Autocad the extent of the .las, .laz files.

When you receive a large amount of point clouds from a Lidar, a scouting plan is a definite help.

The clouds containing less than 1000 points are ignored.

Insert a block for each .las file containing

• 2 Polylines

  • the theoretical area (100m x 100m)
  • the real area in red

• 3 Attributs

  • the name of the file
  • the number of points
  • the date of the survey

Installation

pip install pyautocad
pip install laspy[lazrs,laszip]
