About the BMP file format
Bitmap Image
The Windows bitmap format stores raw, uncompressed pixel data. Files are large but perfectly lossless, with every pixel value preserved exactly as authored.
That pixel-exactness suits height-map workflows where each gray value should map to a precise relief height.
