Kd-490 scale factor

by juliemarie » Fri Jun 16, 2023 6:15 am America/New_York

Hi, I have downloaded the Kd-490 mapped data and I noticed they use a scale factor of 0.0002f. I am wondering why that is, does anybody know?

For efficient storage. A 16bit integer takes less space to store than a 32bit float.
