New OpenJUMP Release
The New OpenJUMP 1.4 - says hello to raster data
The OpenJUMP GIS core developer team is proud to announce the release of OpenJUMP 1.4.
Highlights with this edition:
Again, we deliver better editing capabilities:
- "EZ"-buttons that can be programmed with often used menu functions and used with the "F#"-keys
- drawing of selections can be defined
- invert current selection
OJ 1.4 says hello to raster data:
- support of reading ESRI ASCII grid files as Sextante Raster
- four new raster functions (for images load as "Sextante Raster"):
- Create Lattice from Image,
- Create Polygon Grid from Image
- Profile Graph
- Raster Color Editor
Of course, we also worked on other helpful things, such as:
- optional selection of the CHAR set (international code) when loading shape files
- functions to merge selected polygons with neighbor polygons (similar to ArcGIS "eliminate"), and intersect all polygons within a layer
- OpenJUMP now remembers the window location, size, and maximized state in the workbench-state.xml file and the project files
- better handling of null attributes and date attributes in queries
- five new statistical functions for vector data:
- Create Bar Plot
- Create Histogram
- Create Scatter Plot
- Classify Attributes
- Calculate Mean and Variance per Class
... plus: several bug fixes.

OpenJUMP 1.3 - Better Vector Data Editing & GIS Analysis
Version 1.3 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,
- set attributes of a layer in a batch style using the improved Auto-Assign Attributes function,
- connect or extend existing line geometries when editing with the line tool.
OpenJUMP 1.3 has also new analysis functions that allows to:
- retrieve attribute statistics (min, max, mean, etc.) for the attributes of a layer,
- display maps using different data classification/colour theming methods (e.g. Jenks-breaks method or maximal-breaks method),
- more easily find certain values with the "Search All Attributes" function,
- perform raster image analysis with Sextante directly. I.e. raster layers can be loaded in OpenJUMP and analysed with Sextante.
- create multi-buffers with the Multi-Ring-Buffer function.
Two more additions are of interest for our advanced users that like to customize OpenJUMP for their purposes. First, OpenJUMP 1.3 supports Python, i.e. Jython. This will be the third option to develop and add own functionality (besides BeanShell scripts and Java Plugins). Several Python script examples are delivered with OpenJUMP 1.3 The second improvement has been the introduction of default-plugins.xml file. This files allows to define which functions (especially from the Tools menu) should be available when OpenJUMP is started.
