WARNING: Rugged project moved on to https://gitlab.orekit.org/orekit/rugged¶
Rugged is an add-on for Orekit handling Digital Elevation Models contribution to line of sight computation. It is a free software intermediate-level library written in Java.
It mainly provides direct and inverse location, i.e. it allows to compute accurately which ground point is looked at from a specific pixel in a spacecraft instrument, and conversely which pixel will see a specified ground point. This mapping between ground and sensor is computed with a viewing model taking into account ground Digital Elevation Model, Earth rotation will all its tiny irregularities, on-board sensor pixels individual line-of-sights, spacecraft motion and attitude and several physical effects.
Direct and inverse location can be used to perform full ortho-rectification of images and correlation between sensors observing the same area.
