Integrated Software for Imagers and Spectrometers v3. ISIS3 is a digital image processing software package to manipulate imagery collected by current and past NASA and International planetary missions.
I'm working with ShadowCam images and need to calculate photometric angles (ignoring secondary illumination effects) using ISIS3. However, I don't have access to the SPICE data or the camera model for ShadowCam.
Specifically, I need to calculate:
Incidence angle: the angle between the solar vector and the surface normal
Emission angle: the angle between the surface normal and the observation vector
I plan to use a specific DEM for this calculation. Could someone guide me on how to achieve this in ISIS3, given the lack of SPICE and camera data?
