Hi Peppe,
The Sigma button works now and shows useful statistics.
The Extract min/max tool works well with an 8-bit greyscale. With a 32-bit dem
the tool also runs, but it does not create the point layer for me. The log
does not show anything special. Here are the rows from the log, including
minimal steps
* open a Sextante image into an empty project
* run the Extract min/max tool

When I tried if selecting/deselecting the DEM layer from the layer list of OJ
makes any difference, and playing with the layer drop down menu of the plugin,
I also managed to trigger an error. I do not know yet how to make is happen
always.

HI Jukka,
A new version my Raster Tools is on the pull request .
These are the new things according to your suggestions/tests:
a) I correct the problem with the info tools (Sigma button) due to improper
language code
b) In the Terrain Analysis submenu there is another plugin "Estract min and max
values from raster" which allows to extract min and max values from a selected
raster and display them as styled points in a vector layer
Best regards
Peppe

Hi Jukka, that is an interesting tool. I will work around it, it should not be
difficult to get it. I am travelling and I can work on it after the 27th of
October.
Meanwhile if you find other issues feel free to send me feedback.
The Sigma statistics has to be review, for sure. On the list.

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.

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. Thanks for
the warning

Hi,
I have now RasterTools 3.0.0 gamma [2024-09-30] on my computer. 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?

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.
