Heightmap from numerical data

In case of use only Red channel (0-255) in order to determine peaks, then how to do that here Rob (WriteRGB(HM,x,y,Z,Z,Z))?? I mean scanned return is up to 9000 meters (reality is highest scanned point 6200 meters)..so how to interpret this 9000 meters with so small resolution like 0-255?? I need this data to be accurate from extracted image..how to achieve that regarding writing down pixels in specific color, later used for B3D terrain??
