Hi Everybody, I have just upgraded a new version of my plugin Raster Tools <https://sourceforge.net/p/opensit/wiki/Geo%20Arbores%20Raster%20Tools/>.
Geo Arbores Raster Tools is a set of tools and plugins that extend morphometric raster capabilities in OpenJUMP. It is a pure java software and it is designed to have the minimum dependency to external libraries and very small size (*currently around 1Mb*) thanks to reusing OpenJUMP classes. The tools are available in English and Italian. Raster Tools provides; - a rich toolset of algorithms for Geomorphological and Hydrological analysis, including automatic landscape classifications - several tools for raster analysis (resampling, focal statistics, extract bands, create multiband rasters...) - several overlay raster tools (merge rasters into one, clip raster, zonal statistics...) - convert some raster files to GeoTIFF, not provided by SextanteRaster , included ENVI and ESRI Generic multiband image. - import as vector most used cloud point files, including LiDAR .las files, with a set of options (import only bounding box, import every n points, import only points limited by bounding box of an externa layer. - direct interpolation to raster grid of cloud point layers using Delaunay triangulation - several interpolation methods (linear and natural neighbor Delaunay, IDW, Nearest Neighbor, Spline) of vectors (points and contours) to raster grid - a valid raster 3D viewer adapted from ImageJ <https://imagej.nih.gov/ij/download.html> one (Public domain) The new version is here: RasterTools-2.0.2-28112022.jar <https://sourceforge.net/projects/opensit/files/Openjump/PlugIn/Raster%20Tools/RasterTools-2.0.3-28112022.jar/download> while the source code is available here: RasterTools-2.0.3-28112022.zip <https://sourceforge.net/projects/opensit/files/Openjump/PlugIn/Raster%20Tools/Older/2.x/RasterTools-2.0.3-28112022.zip/download> What are the benefits of Raster Tools: a) The plugin file is small (1 Mb) and contains all the libraries it needs. It is a pure java software b) *RasterTools can work also with OpenJUMP core* c) All the embedded libraries are provided either as public domain (imageJ) or as GNU General Public License <https://sourceforge.net/directory/license:gplv3/> (JEP and some classes of WhiteBOX GAT) * d) I limit the usage of external libraries and tried to reuse all the methods available in OpenJUM e) all the tools are organized into hierarchical menus, following OpenJUMP menu specification Raster Tools project is available as SVN SourceForge <https://sourceforge.net/p/opensit/code/HEAD/tree/Projects/Raster%20tools/OpenJUMP%202/> . *Technical notes* * External libraries into Raster tools define almost 1/4 of the entire jar file: a) JEP <https://sourceforge.net/projects/jep/> java math parse, https://sourceforge.net/projects/jep/. I used jep 2.2 version removing all the table algorithm in order to keep the parser small (only math operations are required). This keep the size of JEP to around 90kb, compared to the one (jep-2.4.2, 540 kb) embedded into OpenJUMP. JEP is used by the raster calculator plugin Currently JEP jar is required by the following plugins of OpenJUMP: Sextante, OpenKLEM and my Raster tools. Sextante and OpenKLEM can easily work using my embedded JEP parser b) WhiteBox GAT GIS <https://sourceforge.net/projects/whiteboxgat/>. This is the last version available on SourceForge. The JAVA project has been dismissed by the author (John Lindsay, personal communication) in favour of the Ruster and Python WhiteBox tools <https://www.whiteboxgeo.com/geospatial-software/>. I reused a few general classes like the LAS reader (for import LiDAR plugin) and a kd-tree (for the IDW and Nearest neighbor interpolation plugins). c) ImageJ <https://imagej.nih.gov/ij/download.html>. I reused a very tiny version of ImageJ to create a bridge between OpenJUMP Sextante Raster framework and ImageJ raster framework, in order to use ImageJ 3D viewer into OpenJUMP Best regards Giuseppe Aruta
