This code was developed for the Mercator Project (LASER Program). The code uses Gaskell's basic infrastructure and data files.
Description
surface_imager takes a bigmap and generates 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 positions 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 - in degrees). Zero azimuth has the Sun due north. 90 elevation is the Sun straight up.
Here's a sample input:
123456 1733 1393 10 90, 0 60, 30 <- low sun angle
Output
- IMAGE.pgm - The output image. Normally, it is 1024x1024 of the field of view (about 24 degrees square).
