RGB bands extraction

[Monica Carriere]

Hi all,

I am trying to extract the red, green and blue channels in raster format from a point cloud , so I can construct an RGB raster in natural color. Which commands should I use? I have tried passing R, G and B values into intensity separately and applying blast2dem separately, but the rasters obtained have a constant value of 255. I am trying as follows (my RGB values are in 16 bit, ranging from 256 to 65280) with red, for example:

las2las -i my input.laz -clamp_RGB_to_8bit -copy_R_into_intensity -olaz -o my output_red.laz

blast2dem -i my output_red.laz -intensity -otif -step 0.5 -o my red raster.tif

 

I would appreciate any help. Thanks in advance.

Greetings,

Monica.

Hi Monica,

a raster output is always a kind of a grid, so please try 

   lasgrid64 -i in.laz -o colored.tif -rgb

Does this work for what you want to do?

Cheers,

Hi Jochen, 

That works exactly as I want to. I tried that same argument other ways and didn't work as intented and gve a mean rgb value raster. Many thanks.

Monica.
