LAS conversion and inspection #19

Closed larsmans closed 10 years ago

larsmans commented 10 years ago

@jiskattema wants scripts for:

inspection of LAS/LAZ files; can be done with lasinfo from LibLAS
finding the density of a point cloud; partially implemented
~~converting LAS to PLY~~
~~converting PLY to LAS~~

larsmans commented 10 years ago

I installed LibLAS. It doesn't build properly with the latest LASZIP because it looks for laszip/laszip.hpp but the latest version installs laszip.hpp (no subdir). I tried to hack up the build script, but eventually ended up working around the issue:

cd ${laszip_install_dir}/include
ln -s . laszip

Solves part of issue #10 only dealing with arbitrary metadata is remaining there.

larsmans commented 10 years ago

Final two points are being solved by @c-martinez.

larsmans commented 10 years ago

Conversions is not essential, skipping that part.

c-martinez commented 10 years ago

LAS files can be loaded using liblas in Python, but conversion requires scaling, offsetting and colour conversion -- nice to have, but might take more time than necessary.
