Axios uDig Extensions release 1.3.1 for uDig 1.2.x
A closed split line can be drown as shown in the screenshot.
The result of split transaction produces:
The split operation is available as a Spatial Operation too. Thus it is possible to split the feature in a layer using lines present in another layer.

UDIG 1.2.0 Release
The uDig 1.2 release process is complete and we are pleased to offer uDig 1.2.0 for download.
This release is made in conjunction with GeoTools 2.6.5.
The uDig 1.2.0 release is available from the main download page.
Installation
Download the package appropriate to your platform, unzip and run:
- Windows
- Linux
- Mac
- SDK: For use with SDK Quickstart instructions
Windows and Linux packages includes a Java Runtime so you really can unzip and run without making any configuration changes to your Machine. On Mac OSX uDig is able to check for Java Advanced Imaging and install if needed. There is also a windows installer.
To get started with uDig:
- Help Menu provides a Quickstart
- Walkthrough 1
- Walkthrough 2
About uDig 1.2 Series
The uDig 1.2 series highlights a lot really great ideas the developer community has been working on. We have migrated to a modern version of the GeoTools library - bringing in five years of new developments in standard support, and a host of new raster and vector formats. An exciting addition is the use of the ImageIO-ext project allowing the use of raster formats supported by GDAL.
New and capabilities of uDig 1.2 include:
- ImageIO-EXT rendering enabling additional raster formats and working with images larger then memory
- On select platforms MRSID and ECW raster support
- Tiled rendering (as an option in preferences) with a new flicker free panning tool.
- Support for GeoWebCache and TileCache via WMS-C
- WFS 1.1.0 support (read-only)
- Greatly improved ArcSDE support; multithreaded and faster
- Advanced Symbology including Hatches and True Type Font support
About uDig 1.2.0
Features and capabilities of this release:
- Access to GeoTools DataStores via a generic wizard allowing users to connect to many additional data formats and access all connection parameters.
- One long standing difficulty with using large datasets is uDig wanting to know the bounds of the data (so it can efficiently search, zoom). For common spatial file formats this data is known and available; for large databases such as DB2 and PostgreSQL this can take some time to calculate. For the generic GeoTools DataStore wizard above we are experimenting with using bounds based simply on the valid area for coordinate reference system provided by the data.
- The valid area of the coordinate reference system is also used when "clipping" WFS requests resolving some long standing issues when editing WFS services that do not update their Capabilities document.
- Advanced: Control what features are requested for a layer using a Common Query Language (CQL) expression. The expression builder offers command completion with the full GeoTools function list available as you type
- Advanced: Cache support added allowing you to cache Raster layers in memory (please be working with large datasets as this is the first time uDig is allowing users to cache information in memory). Please note that raster file formats on disk are optimised and in may cases perform better than caching in memory. Caching in memory is recommended for formats such as jpeg (where the entire image must be loaded to display even a small section) and when working with data from a slow device such as the network or DVD.
- Experimental: Cache support added allowing you to cache WFS layers in memory for increased performance (please be careful when working with large datasets as this is the first time uDig is allowing users to cache data in memory)
- Enhanced Vector Editing
- Revamped printing support, standard paper sizes are supported when printing
- Import multiple layers into the catalog at once
- switch between common map scales
- Improved Drag and Drop support allowing multiple layers to be manipulated at once
- Drag and Drop treats URL as a distinct content type across browser implementations
Notes and documentation for developers:
- Service and GeoResource Interceptors Docs
- Interceptors Docs
- Review of the dependencies used by the uDig SDK with license and build advice
- We have transitioned to a modern version of GeoTools allowing for a more productive relationship with the larger community
- Support for the "JDBC-NG" rewrite of GeoTools Database access
- Uses the latest Eclipse 3.6.0 "Helios" release for an industrial strength plug-in system
- Uses the latest "Babel" project translations

Open Source Blueprint
Recently Michelle Ballinger has been writing up an "Blueprint for Creating an Open Source Web Map" which includes a section on uDig. It is nice to see Penn State encouraging students to get out there in the world and make positive contributions; and it makes a change from the endless survey requests open source projects are asked to fill out each year.
If all goes well we will collect these instructions for the uDig online help. Thanks for taking part in open source Michelle.

Google Summer of Code 2010
Davide Savazzi, a student at the Università degli Studi di Pavia, Italy, and an experienced GIS developer, is doing a project titled 'Adding support for Neo4j graph database in Geotools and uDIG'. We are particularly excited to have Davide involved in this project because he has already made core contributions to the underlying 'Neo4j Spatial' project, which is building GIS capabilities into the graph database itself.
Introduction
Geographic vector data is naturally structured like a graph, network and topological analyses view GIS data as graphs, but so far no-one has tried to make use of a real graph database as the backing store for a GIS.Neo4j is a new open source database that stores data as a graph, in the mathematical sense of nodes connected by relationships, with both nodes and relationships storing properties as key-value pairs.
The goals of the project are:
- extend Neo4j graph database with spatial indexing and query functions.
- enable GIS application developers working on either or both Geotools and uDIG to use Neo4j as a true spatial database.
- enable GIS users working with uDIG to perform spatial analyses better or faster than normal.
Roadmap
At the highest level, the project will take the following phases:- define the best approach to store spatial data in Neo4j graph database
- create spatial indexing and query functions for Neo4j
- create a Geotools DataStore that can read and write spatial data contained in Neo4j
- add a Catalog to uDIG for this new DataStore
- add persistence support to Geotools graph module through Neo4j
- prototype a plugin in uDIG for network / routing analyses
Further reading
Here are a few links worth investigating, for those of you interested in some background on this subject:- Neo4j Spatial Support (uDig Wiki)
- Google Summer of Code for Neo4j Spatial (Neo4j Wiki)
- Neo4j Spatial
- Neo4j graph database
- Proposed talk at FOSS4G - Neo4j Spatial - backing a GIS with a true graph database (go to http://2010.foss4g.org/review/ before the 14th May to vote for it)
