All, I have just implemented a number of options in las2las that allow you to fetch color information from a GDAL-readable raster. I would like to thank Aaron Reyna for the Autzen_Stadium data that exists on the http://liblas.org/samples sample library that made it easy to test and implement. This new method in las2las should be considered a replacement for the Python implementation that is available for download if you have a source release of libLAS.
> --color-source arg A string to a GDAL-openable raster data source. > Use > GDAL VRTs if you want to adjust the data source or > set its coordinate system, etc. > --color-source "afile.tif" > --color-source-bands arg A list of three bands from the --color-source to > assign to the R, G, B values for the point > --color-source-bands 1 2 3 > --color-source-scale arg A number used by --color-source to scale the input > R, G, B values for the point. For example, to > scale the 8 bit color data from an input raster to > 16 bit, the 8 bit data should be multiplied by > 256. > --color-source-scale 256 > This new functionality will be released in 1.6.0b3.
