Hello,
One answer would be to use RIEGL scanner where "normalized reflectivity" can be exported to the LAS file in form of "extra bytes".
Or i could add this as a feature - likely to lastrack because we would require trajectories - but i do have many more feature requests on my plate. How should such an intensity normalization step be implemented (assuming all is flown by the same scanner)? Suggestions?
Steven told me someone that he was contacted in a private email off-list by a service provider who gave me a little advice. They basically said that intensity normalization usually isn't that important and they aren't aware of any free tools for it. However, they and probably other contractors have custom tools and will provide it as a service if requested by a client.
Steven ended up not needing to perform the normalization for my original purpose, which was to create a good looking image that he could use for georeferencing aerial photos. However, he could see normalized intensity statistics being potentially useful as canopy metrics for forestry. To him it seems like very few people attempt to use intensity metrics when estimating forest structure or classifying trees, but he thinks it's possible that these metrics often don't end up being significant in classifiers partly because they aren't normalized.
He would only suggest adding it if I think it wouldn't be that difficult and if other people in the community would be interested in it.
Regards,
Martin @rapidlasso
