Hi! Thanks to Hamish we can now easily convert LAS files to DEMs with r.in.xyz.
To remind, LAS Tools can be found here: http://www.cs.unc.edu/~isenburg/lastools/ I successfully compiled and used it like this: 1) in las2txt.cpp (lastools/tools/src): change main to return int: int main(int argc, char *argv[]) 2) g++ ../../src/lasreader.cpp las2txt.cpp -I ../../inc/ -o las2txt -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 3) ./las2txt test.las -otxt | r.in.xyz input=- output=dtm method=min fs=" " > As a start we can include references to the LAS tools in the relevant man > pages and wiki, with build and useage examples.

I absolutely agree with you. But don't know how complicated this implementation will be and I'm not a programmer, so I cannot really support.
