uDig Welcomes back Axios Spatial Editing Tools

The much loved Axios Spatial Editing Tools are back! These tools are included in latest uDig 1.3.2 release and do not require a separate download.

Thanks to the supportive community I was able to apply for Google Summer of Code 2012 and succeeded in porting the Spatial Tools available to the latest uDig. This success is due to the large commitment of Anne Ghisla (OSGeo SoC Administrator), Mauricio Pazos and Andrea Antonello (my two mentors) and Jody Garnett (teacher of a wonderful kick-off course). Thank you!

The project outcome is available to all of you in the uDig 1.3.2 release.

The Spatial Editing Tools provide facilities to perform key geometry editing tasks:
  • Split
  • Merge
  • Create Arc
  • Create Parallel
  • Trim
These tools behave as they did in uDig 1.2 but ...


In addition to the Merge Tool, there is now a new Merge Operation!

A new work flow has been created: now it is possible to select features using Box Selection Tool (or Table view), right-click on them and fire a "Operations --> Merge Selected" action.
This allows feature selection to be controlled directly in the Map window, relying on the selection refinement capabilities of the Box Selection Tool (Ctrl+Click to remove, Shift+Click to add).

In shorts, Merge Tool usage should be now much more 'user-friendly'!

The uDig Community is pleased to announce the release of the uDig 1.3.2.

This point release packs significant new functionality. Thanks to our Google Summer of Code students for taking part in this years program. Macro Foi completed his work porting the advanced edit tools into this release.

There are a large number of people to thank for the nuts and bolts of this release. Cliff Broadbent and Sam Guymer transitioning the project to the tycho build system. Andrea Antonello setup the dropins folder for easy plugin installation. Jody Garnett and Frank Gasdorf ported the documentation and walkthroughs into Restructured Text resulting in a nice clean look.

This release is made in conjunction with GeoTools 8.1.
