SatVu's thermal imagery product includes imagery in representative digital numbers - where zero is the coldest pixel in the image, and higher numbers show warmer pixels. Using GIS software, these digital numbers can be converted to colour.
The image files we provide use the SatVu colour scale, where dark blue is the coldest, and orange is the warmest.
