Hi, With a DEM opened as a Sextante image the tools work fine. Pretty nice, even I do not know yet what to do with all of them. I tested with 3000x3000 pixel sized file because we have plenty of those and the algorithms run very fast with them. I found one issue: In the Frequency distribution, pressing the Sigma button starts something that obviously does nothing or at least gets never ready, and it is impossible to stop the process. The Cancel button has no effect, nor does the red cross. I had to kill Java with the task manager.
By change just last week I tried to find a raster tool that would report a minimum and maximum value from a raster AND the locations of the extremes, either as pixel coordinates or georeferenced coordinates. I did find some examples about finding them with numpy https://en.moonbooks.org/Articles/How-to-find-the-indexes-of-the-minimum-or-maximum-values-in-a-matrix-using-python-/. Now I was hoping that perhaps I could find such a tool from your toolbox, but I could not. However, I believe that some of the existing tools already have that information, and there should only be on option to write it out. Especially the 3D viewer seems to have everything ready. For my needs it would be enough to save just one vector point feature for the minimum and another one for the maximum, even if the DEM contains large flat areas like sea. Min and max would be used for spreading a color ramp along the full range, and vector data for visualizing the locations. Do you believe that such tool could have general interest among users? An advanced tool could take a polygon as input and report min/max values from the interior of the polygon. -Jukka- Lähettäjä: Giuseppe Aruta <giuseppe.ar...@gmail.com> Lähetetty: maanantai 14. lokakuuta 2024 11.25 Vastaanottaja: OpenJump develop and use <jump-pilot-devel@lists.sourceforge.net> Aihe: Re: [JPP-Devel] Upgraded RasterTools to version 3.0 beta Hi Jukka, the import raster of Raster tool is mainly a converter: it converts to tif formats which are not supported by OJ, eventually users can open them into OJ workbench view. Regarding the conversion of JPG, PNG and TIF (which are supported by Open jump sextante open file), it is an extra: it uses Commons Imagining instead of Image Io libraries. I added just in case it was impossible to open these files by regular open sextante. It is a work in progress: I recommend you to use regular "open sextante" with your tiff Fike and then to use "Raster tools". I will give it a look anyhow to correct the bug.

I was planning to test the terrain analysis tools but I am confuced. My source DEM is float 32 Band 1 Block=3000x1 Type=Float32, ColorInterp=Gray but when I import it with the Import raster option it gets changed into 8 bit RGB. This is what gdalinfo reports about the converted image: Band 1 Block=3000x8 Type=Byte, ColorInterp=Red Band 2 Block=3000x8 Type=Byte, ColorInterp=Green Band 3 Block=3000x8 Type=Byte, ColorInterp=Blue Am I doing something wrong? -Jukka Rahkonen- Lähettäjä: Giuseppe Aruta <giuseppe.ar...@gmail.com<mailto:giuseppe.ar...@gmail.com>> Lähetetty: keskiviikko 25. syyskuuta 2024 12.02 Vastaanottaja: OpenJump develop and use <jump-pilot-devel@lists.sourceforge.net<mailto:jump-pilot-devel@lists.sourceforge.net>> Aihe: Re: [JPP-Devel] Upgraded RasterTools to version 3.0 beta THe new version of Raster Tool 3.0 beta is available at the following link: https://sourceforge.net/projects/opensit/files/Openjump/PlugIn/Raster%20Tools/RasterTools-3.0.0beta-20240918.jar/download <https://sourceforge.net/projects/opensit/files/Openjump/PlugIn/Raster%20Tools/RasterTools-3.0.0beta-20240918.jar/download> S<https://sourceforge.net/projects/opensit/files/Openjump/PlugIn/Raster%20Tools/RasterTools-3.0.0beta-20240918.jar/download>ouce code is available here: https://sourceforge.net/projects/opensit/files/Openjump/PlugIn/Raster%20Tools/Older/3.x/RasterTools-3.0.0beta-20240918.zip/download In a few day we hopefully can integrate this new version into the current development snapshots of OpenJUMP Giuseppe Aruta Il giorno mer 25 set 2024 alle ore 10:50 Giuseppe Aruta <giuseppe.ar...@gmail.com<mailto:giuseppe.ar...@gmail.com>> ha scritto: Hi all Today I upgraded RasterTools to version 3.0 beta. The main highlights are the following: a) Reorganized menus in a more simple and intuitive order b) added a 'Recent used tools' menu with the list of the last 10 used plugins c) Enhanced 'Help' option as a tree of documents d) Added 'Warp raster' toolbox to warp images using affine, perspective and bicubic transformation e) Added Multiflow accumulation algorithm (Freeman, 1991) f) Added export raster to KMZ with embedded legend for single banded raster. The complete set of tools (some are multitools) now reaches the number of 70, mainly built using the huge reference available (a list of the minimum reference is available on the help option). Together with Sextante and OpenKLEM, Rastertools will probably cover not all but almost the need for a teaching class and a base professional project, which includes: 1) land classification 2) hydraulic, visibility, cost/path, math, statistic analysis 3) creation, visualization, elaboration and overlay of images. In the future, the brench 3 of RasterTools will be used for the correction of bugs and a better integration of the tools to OpenJUMP, OpenKLEM and Sextante.
