The tests suite is the first place to look for getting help with Rugged use. Several tutorials are also provided with the source code in order to emphazise particular use cases:
Direct location
This tutorial explains how to initialize Rugged and use it to geolocate
a satellite image.
Direct location with DEM
The aim of this tutorial is to compute a direct location grid by
intersection of the line of sight with a DEM (Digital Elevation Model),
using Duvenhage’s algorithm.
Inverse location
The aim of this tutorial is to compute the inverse location of a point
on Earth in order to give the sensor pixel, with the associated line,
seeing this point.
Matlab examples
Examples of direct and inverse location were provided by the Centre de
Techniques Spatiales of the Algerian Space Agency.
