This code was developed for the Mercator Project (LASER Program). The code uses Gaskell's basic infrastructure and data files.

surface_imager

The program takes a bigmap and will generate a surface image as if you are standing on (or near) the surface. It is designed to have a 100mm focal length lens and generate a 1024x1024 image.

Input - files

• none

Input - stdin

• Bigmap name
• Location of the point of view (x, y, z). X and Y are pixel position within the map. Z is in meters above the surface.
• Direction that you are looking (azimuth and elevation - in degrees). Zero azimuth is looking due north. Zero elevation is looking at the horizon.
• Sun position (azimuth and elevation (azimuth and elevation - in degrees). Zero azimuth has the Sun due north. 90 elevation is the Sun straight up.
