Are there any articles out there that give advice on choosing/adjusting color maps for a particular situation?
I understand why some maps are awful, but have had a hard time finding a color map which I like perceptually for interpreting LIDAR forest canopy maps.
I've tried using viridis and a few others, but exceptionally tall trees get lost in the noise (not enough contrast), especially when using transparency to overlay canopy height on the LIDAR intensity data.
Is this just a case of not clamping the ends of the range properly?
- semi-extrinsic 8y agoI guess if your underlying data is not uniform, a uniform color map isn't going to do great? Say, if you have a bimodal underlying distribution and you're interested in coloring according to quantiles, you want to have a similarly bimodally distributed color map. The easiest way to achieve this is to compute the quantiles for your data set, and color by that (rather than height).
