The data that I download from USGS is 32 bit floating point data. What’s the correct procedure for dealing with USGS data? Should I step it down to 16 bit or 8 bit? Does it require tonemapping?
When I bring it in as-is, the terrain doesn’t look correct. But when I “Equalize” the histogram in Photoshop (Image > Adjustments > Equalize), and save as a 16 bit file, the terrain looks better–but I’m unsure if it’s entirely accurate. Accuracy is important with the project I’m working on.
