OpenStreetMap *.osm file reader plugin available

We have been working hard on a plugin to read OpenStreetMaps .osm and files. Since today you can download the latest plugin version (1.0.4) from our plugin > driver section, or get it with the latest nightly build of the PLUS version. This means, OpenJUMP 1.6.4 PLUS will have this driver included.


  • If you use the driver, then, dependent on the file size, you need to assign sufficient memory, which is about 2-3 times the file size. For instance for a 400 MB .osm file, you would need to assign about 1GB of RAM memory to OpenJUMP. This number holds only for osm files. For files you need much more (8 times?).
  • Also the data will be in geographic coordinates, i.e. WGS 84 (EPSG:4326). That means, buildings may look skewed. To get the data into a normal perspective you would need to use OpenJUMPs CTS extension and transform the layer into your regional cartographic projection (you can find more about it on the OpenJUMP wiki).
  • Read the log messages under Window > Log, if any objects have been excluded or could not be found. For instance, some relations miss elements. So there is no guarantee that everything contained in the file is shown.

OpenJUMP GIS 1.5.1 is shipping

The past week OpenJUMP team has released OpenJUMP 1.5.1. As usual we added functionality and fixed bugs - since our last release. However, we made a hopefully user friendly decision: we will distribute a CORE and a PLUS version.

The CORE version is the usual OpenJUMP version. The PLUS version will contain OpenJUMP plus a number of useful plugins. For instance Sextante for raster analysis (still Version 0.6), CadPlans PrintingPlugin for… well.. printing, DXF driver, PostGIS connector (for writing to PostGIS), Graph Analysis and Topology tools - that can be used for Quality Assurance, the Chart Plugin for creating charts, Beanshell editor etc.... read more

new OJ 1.4 and Sextante 0.6 bundle

So the bug reported a few hours ago could be fixed (see below) and a new bundled version (under: win32 / 1.4 / Sextante) and a new binding library (under temp) was uploaded.

How to identify if You have a buggy OJ-Sextante bundle?
a) create a layer A with some points and a layer B with some other points in a different location
b) open the sextante toolbox and calculate "density (kernel)" from these layers - with two different search radi (e.g. 200m and 800m), so you obtain Raster A-Density and Raster B-Density
c) create with the sextante function "slope" from each raster a slope raster (Slope is more or less the first derivative of the density). so you obtain Raster A-Density-Slope and Raster B-Density-Slope.
d) Check if these two rasters: look different (because of the different points and different search radii) and are in a different place. If both is true then you have the fixed version, if the results look somehow very similar or error message appear, you have an old version.

to Sextante users: OJ 1.4 Sextante bundle

Hei all,

The OJ-Sextante bundle released yesterday (26th/27th) is still buggy. I removed it from the OJ 1.4 downloads, as well as the binding.

Doing some more testing this morning revealed that I need to change the bindings for Sextante as well, otherwise wrong rasters may be transmitted to sextante e.g. data from raster A loaded after raster B - when raster B should be transmitted (my original fix, yesterday worked with OJ internal interface).
I try to resolve the bug as soon as possible and make a new release of the OJ 1.4-Sextante bundle.... read more

OpenJUMP GIS 1.4 out now

Dear users, we released OpenJUMP 1.4 tonight. Highlights are the ez-buttons, more raster support functions, inversion of selection, statistical analysis functions, etc. More info on the new functionality can be found on our wikipage.

Please note that OpenJUMP 1.4 downloadable from 24-26th of October contained a bug for raster-data processing. So all Sextante and raster users should download the new 1.4 version (actually shown as Version in the spash screen )

New OpenJUMP 1.3.1 Maintenance Release

Hei all,

today I made a maintenance release, due to a tiff-file export bug discovered and reported earlier (see news). Note that there are still problems occuring with loading raster files (using the different systems: build image loader and Sextante Raster Image loader).

A new feature of 1.3.1 is a better support for PostGIS queries allowing to use the view/fence parameters (thank you to Michael).... read more

pirol/sextante raster image export bug fixed


today I discovered a problem with the tif image export for raster files if for instance Sextante raster processing results should be exported. Unfortunately the export function shifted the images by 0.5 pixels towards NW (since the current implementation did not respect that the world file coordinate is given for the center of the first pixel - and not the pixel corner)

I did a bug fix an hour ago. I hope that tomorrows nightly build contains this fix. ... read more

No Virus infected openjump.exe

Dear User,

we got lately several reports that openjump.exe contains a virus or trojan. We can not confirm this and believe the reason is that openjump.exe simply calls openjump.bat.

Here is a link to an online check of the file which suggest that openjump.exe is clean:

This version has better editing capabilities, so the user is able to:
* faster digitise polygons due to the new Auto-complete Polygon tool,
* mark points of interest with the new Note Tool,
* simplify polygon coverages without creating slivers between adjacent polygons,
* compare different editing versions with the new Synchronize function that allows synchronized panning and zooming between two map windows that show different data,

moving Sources from CVS to SVN


our development will now take place on the sourcecode in the SVN repository. The source code of the CVS repository can still be accessed, but its not more maintained / updated.
To get access to the current SVN sources within Eclipse, you can use the Subclipse PlugIn. The devlopement takes places on the "trunk" version (not the "stable" branch).

To our OpenJump Windows users: we missed to include the option, that plugins are loaded if one starts the programm by clicking on the desktop icon. To enable this, please right-click on your icon and select the icon “properties”. Then look for the “target” field. Here add at the end:
-plug-in-directory “C:\Programme\Openjump\lib\ext”
