I'm interested in finding a 30 meter DSM (digital surface model that includes canopy) from SRTM with the hope of creating a 30 meter canopy height model. I know that it can be done because the following studies have:
However, I can't for the life of me find DSMs, only DEMs. Does anyone have any suggestions for where to look online? Or do I need to contact JPL or some other agency directly? I'm also entertaining the idea of ASTER, but am finding those data to be equally challenging to locate.
