Description
Some vendors provide intensity as UInt8, others as UInt16, and it's not always clear how they've normalized the relative raster intensity values they deliver (in most cases, these are raw intensity/amplitude, not estimates of reflectance scaled by range, which would be nice). This is not an issue for elevation values, fortunately.
See attached example (note low contrast intensity for tiles near southern portion of AOI)
I don't have a simple solution to this right now, but just something to be aware of. Likely need to use global point cloud statistics for intensity values of each 3DEP project within the AOI, and normalize each project accordingly.
I also noticed the output intensity raster is Float32. I think we can likely get away with scaled UInt16, maybe even UInt8. I remember some discussion on data types and filesize optimization with Karthik last year.
