l2d_classify

[ahmadshabbir2468]

Hi, Sir I have a las File and I want to classify It. I am successfully Classify Las Files as Ground Vs Non Ground But i want to classify Each Component separately, For Example separately Classify ROADS ,power lines, Trees , Water , Houses Separately from 1 file

AND I Read These line from Our documentation

It does not matter if the LAS files are already classified, lidar2dems will classify them, ignoring the existing classifications "If a site file is provided, there will be a single classified las file for each polygon."

Can You Explain This Line ??
Each Polygon Means ? Our Tool can Differentiate Only Between Ground vs Non Ground Elements OR It Can also Differentiate Between Houses , Roads, Water , And Trees ,power lines

This is a non-issue.

Please read the first line of http://applied-geosolutions.github.io/lidar2dems/doc/l2dclassify.html.

The l2d_classify script is used to classify unclassified point clouds into ground and non-ground points.

The polygons are simply for selecting/cropping regions within your data.

Hello all,

@chambbj is correct that the polygons are simply for cropping the data.

@ahmadshabbir2468 -- The only classifications that are done in lidar2dems at this time are into Terrain (ground), Surface (highest non-ground), and Canopy (the difference between the DSM and the DTM). Classification into houses, roads, water and forest can be done, but is not integrated into lidar2dems.
