Hi Jumpers
OpenKLEM is a set of tools for basic raster and hydrological analysis
http://ojwiki.soldin.de/index.php?title=Plugins_for_OpenJUMP#Raster_Analysis
.
One of our member, Alberto De Luca, has been involved on OpenKLEM
development. The software is used by Prof. Roberto Rossi in his course Gis
Applications in Hydrogeology (University of Padua -
https://didattica.unipd.it/off/2017/LM/AV/AG0062/000ZZ/AG01122459/N0).
In the last 2 months, in agreement with Alberto and Roberto, I reworked
OpenKLEM source code to reduce the depencies of OpenKLEM to external
libraries (mostly OpenDocumet ones). And to make a copy of working OpenKLEM
smaller in size and connected only to OpenJUMP plus libraries.
This reduced OpenKLEM setup from 8 files(2 core files + 6 OpenDocuments
onse)-7 Mb to 2 core files-1 Mb.
My proposal in this mail is to integrate OpenKLEM to OpenJUMP PLUS.
These are the advantages and integration with OpenJUMP. And a comparison
Sextante:
1) Raster instrumentation enrichment
the hydrographic analysis tools in OpenKLEM increases the offer of
Sextante's raster instrumentation
2) Basic raster tools:
Sextante has a more extensive set of basic raster instrumentation. But some
of these have unresolved bugs (due to scarce users). Such as the "Sextante>
Basic Hydrological Analysis> Sink Fill" tool. The equivalent OpenKLEM tools
seem to work properly.
3) Availability of the source code.
OpenKLEM: The raster wrappers used in OpenKLEM are integrated into one of
the two installation files. The source code is available for any changes /
inspections.
Sextante: The source code of the wrapper and gui of Sextante (sextante.jar
and sextante-gui.jar) integrated in OpenJUMP (ver 1, I believe) is not
available (unless Stefan still saves a copy). GvSigCE has a recent version
(2014) of Sextante still subject to developmen untill 2017t. I tried to
recompile t it for OJ and found more dependencies to GvGIG libraries. I
suspect that by now the two Sextante (OJ and GvSIGCE are fork)
4) Users
Sextante. Apart from me I do not know other users who regularly use Sextante
OpenKLEM. It is used in an annual university course in Padua
Documentation: There are some papers and thesys about the usage of
Kinematik Local Excess Model (KLEM, the hydrographic model used by
OpenKLEM). In Italian.
I can resume the basics and try to make a brief documentation about the
tools, in English.
Source code. I can integrate OpenKLEM source code into OpenJUMP repository
Copyright: GNU General Public License. Alberto, you can correct me ;)
In this folder you can find OpenKLEM, its source code and the instruction
to setup:
https://sourceforge.net/projects/opensit/files/Openjump/OpenKLEM/
I hope I have been brief and exhaustive. Waiting for your opinions
Best regards
Peppe
