Introduction
SEXTANTE (Sistema EXTremeño de ANàlisis Territorial) is a library of geoprocesses developed in Java by Victor Olaya. It has more than 280 algorithms that cover many areas within the geospatial analysis, both raster and vector. SEXTANTE is embedded into major opensource GIS projects, such as gvSIG, OpenJUMP or uDig, and in free/propetary non-java projects like QGIS and ArcGIS. Sextante is distributed with OpenJUMP PLUS version
Documentation
The following documents (PDF, in English) are available on OpenJUMP web site:
- Introduction to Sextante. A complete manual of all the functions available on Sextante.
- Sextante Programming Guide. How to program a Sextante plugin
- Sextante List of Algorithms. The complete list of Algorithms available on OpenJUMP Sextante
There is also a YouTube channel (SEXTANTE Geospatial Library) on how to use Sextante.
A well done documentation is also provided via Sextante>Sextante help context menu as Html files
Examples of Sextante Raster Algorithms
The following tables show some algorithms for Raster analysis, referring to analogous in ArcGIS Spatial Analyst
Geomorphology
| Spatial Analyst | Sextante |
|---|---|
| Slope, Aspect, Real area (Terrain) | Slope, Aspect, Real Area (Geomorphometry and Terrain analysis) |
| Viewshed (Terrain) | Visibility (Visibility and Lightning) |
| Hillshade (Terrain) | Shaded relief (Visibility and Lightning) |
Technical notes
- OpenJUMP Sextante binding is the file ojsextante_binding_XXX.jar (where XXX is the date of build) located into OpenJUMP/lib/ext folder
- the core of Sextante software are the files: sextante.jar, sextante_gui.jar and sextante_algorithms.jar located into OpenJUMP/lib/ext/sextante folder
- There are other files located into ext/sextante folder which are needed as external libraries by sextante, such as jfreechart and common.
- Source code of Sextante is stored by GvSIG CE repository

[April 2015] ''Sextante Modeler'' and ''Sextante History'' have been deactivated in OpenJUMP Night Snapshot
due to the presence of bugs that make those functions not usable
