4.0

Version 4.0 is a major release.

Highlights in the 4.0 release are:

Made Rugged able to deal with seamless DEM tiles (no overlapping constraints)
Fixed Duvenhage algorithm for coupled time light correction and non nadir view
Fixed light time correction in atmospheric refraction computation
Updated dependencies to Orekit 13.0.3 (and Hipparchus 4.0.1)

3.0

Version 3.0 is a major release.

Highlights in the 3.0 release are:

• Fixed longitude normalization issue with tiles
• Fixed inverse location issue with atmospheric refraction
• Updated dependencies to Orekit 11.2 (and Hipparchus 2.1 )

2.2

Version 2.2 is a maintenance release.

This version mainly:

• adds access to algorithm identifier,
• corrects an Earth constant for model IERS96,
• allows automatic building, release and code analysis with Gitlab CI.

Version 2.2 depends on version 10.2 of Orekit and version 1.7 of Hipparchus.

2.1

Version 2.1 is a minor release.

This version mainly adds refraction correction in inverse location.

Version 2.1 depends on version 9.3.1 of Orekit and version 1.4 of Hipparchus.

2.0

Version 2.0 is a major release.

This version mainly provides a refinement feature (i.e. adjusting the viewing model parameters to match ground control points). It also introduces refraction effects in the mapping between ground points and on-board sensor.

Version 2.0 depends on version 9.1 of Orekit and version 1.2 of Hipparchus.

1.0

Version 1.0 is the first official release of Rugged.

Rugged provides accurate direct and inverse location functions between terrain and spaceborne sensor. Currently, only push-broom sensors are supported.

This version is identical to the version that is operationally producing the images for ESA Sentinel-2 mission since end of June 2015. It is therefore a flight-proven version.

Version 1.0 depends on version 7.1 of Orekit and version 3.6 of Apache Commons Math.
