GeoTools 8.5 released

The GeoTools community is pleased to announce the availability of GeoTools 8.5 for download from source forge:
This release is also deployed to the OSGeo Maven Repository. For more information on setting up your project with Maven consult the Quickstart.

About GeoTools 8.5

This is a bug fix release containing a number of fixes and improvements, including:

  • several fixes to rendering transformations allowing several transformations to be chained together  in the same rendering request (e.g., interpolate values from discrete points and then also extract isolines from it)
  • fixes to date/time handling in CQL
  • spotted and fixed a deadlock in the rendering subsystem happening if the renderer gets abruptly stopped while working against a very fast data source (or a very slow Graphics2D implementation)
  • a new PullParser class allowing for better streaming parsing of large amounts of XML (e.g., GML, KML)
  • better handling of raster "no data" during reprojection, avoiding border artifacts in the results
  • a new Oracle specific filter function exposing Oracle spatials's K nearest neighbor search
Full details are available in Jira's release notes.



Upgrading from GeoTools 2.7

For those migrating from GeoTools 2.7, upgrade instructions are available. No additional GeoTools 2.7 released are scheduled.

FeatureCollection cleanup

The FeatureCollection cleanup proposal is now complete. The first batch of work went into the GeoTools 8.0 release, this second phase removes several methods from FeatureCollection. These methods were not widely implemented, and as a result not adopted by client code.
Upgrade instructions are available: As part of this work Andrea provided an extensive review of the existing FeatureCollection implementations and a number of utility methods have been introduced to make working with features easier:
  • DataUtilities.visit( FeatureCollection, FeatureVisitor, ProgerssListener )
  • DataUtilities.bounds( FeatureCollection ) // Already existed
  • DataUtilities.bounds( FeatureIterator )
  • DataUtilities.count( FeatureCollection )
  • DataUtilities.count( FeatureIterator )
  • DataUtilities.close( Iterator )
  • DataUtilities.first( SimpleFeatureCollection ): SimpleFeature
  • DataUtilities.first( FeatureCollection ): F
  • DataUtilities.list( FeatureCollection ): List  // Already existed 
  • DataUtilities.list( FeatureCollection, int ): List
  • DataUtilities.iterator( FeatureIterator ): Iterator // also Closable 
  • DataUtilities.collectionCast( FeatureCollection ): Collection
For additional information, and an overview of the FeatureCollection implementations please review the detailed change proposal.
If you cannot make the transition today:
  • A milestone 9.0-M0 release has been deployed to maven. 
  • To switch your maven pom.xml over to 9.0-M0: 
    <properties>
   <geotools.version>9.0-M0</geotools.version>
</properties>
...
<dependency>
  <groupId>org.geotools</groupId>
  <artifactId>gt-main</artifactId>
  <version>${geotools.version}</version>
</dependency>
  • You can use this milestone release as a rest area until you have time to upgrade.
One of the joys of working on a large stable project such as GeoTools is the gradual change of pace, and the careful planning that goes into keeping projects working together:
  • The initial GeoTools 2.0 rewrite provided a clear FeatureResults API acting in a fashion similar to a JDBC ResultSet.
  • GeoTools 2.1 introduced FeatureCollection as a superclass of FeatureResults, bringing in the java.util.Collection methods being removed today. This was motivated by an amusing Bring Back FeatureCollection rant from our founder James MacGill - well we tried James and it was a bad idea.
  • The transition to Java 5 forced us to remove direct use of the java.util.Collection interface, however we kept the methods for backwards compatibility. It was too easy to introduce a resource leak with the Java 5 for-each syntax:
for( Feature feature : featureCollection ){
    System.out.println( feature.getID() );
}
  • With todays change GeoTools programs are ready for the Java 7 try-with-resource syntax as shown below:
try( FeatureIterator iter=featureCollection.features() ){
   while( iter.hasNext() ){
        Feature feature = iter.next();
        System.out.println( feature.getID() );
   }
}

GeoTools on GitHub

As a follow up to our earlier post, GeoTools considering a switch to git, we are pleased to report a successful transition to GitHub last weekend (Happy Canada Day).
Network Graph Showing 2.7, 8.0 and future "master" 9.0 development
The change proposal, Transition to GitHub, has the details on what was involved in changing over.

A massive thanks to Justin DeOlivera for setting up the origional GitHub mirror, transitioning the committer list over to GitHub, updating the build boxes to checkout from the new repository, the release scripts to tag correctly and so forth. With any transition supporting the developer community is critical, and Justin has done a great job answering questions about git (and filling in lots of docs with the details).

This release includes 62 between bug fixes and improvements. Some of the highlights include:
  • spatial filtering within SLD works fine also when using coordinate reprojection
  • a new GeometryBuilder that makes it easier to create geometries from code
  • better 2.5D data support, including database support and output encoding in GML and JSON (expect more work in this area)
  • improved SQL Server data store
  • more robust HSQL EPSG database (can recover from connection losses)
  • a set of small improvements to the WFS data store
  • a new version of the OGR data store in unsupported land based on the BridJ library
And much more. Check out the release notes for all the details.

We also want to take the occasion to thanks the hard work of all core developers, and a special mention to non core developers that contributed patches and code to GeoTools:
  • Jared Erickson, for adding new filter functions (minimum circle, minimum rectangle
  • Ken Bisland, for a better SRID lookup logic in SQL Server
  • Oscar Fonts, for the similarity transformation
  • Shane StClair, for adding UUID support in DataUtilities and shapefile output, and fix a timezone issue in time conversion
  • Jan De Moerloose, for making GeoTools work better within GWT apps, making SLD resource locators pluggable, and fixing handling of some spatial filtes in FilterDomParser

  • Martin Davis has been putting forth some great patches as of late, most recently centered around supporting 3/2.5D data making its way through the entire "stack".
Thanks to the GeoTools tribe for starting up the release train. We are looking forward to GeoTools 8.0 being available.

GeoTools considering a switch to Git

Hi all,
the GeoTools developers have been working, so far, with Subversion as the main version control system. However various core developers have been using Git as a SVN client for quite some time so far, and an official mirror of Geotools, automatically kept in synch with Subversion, is already available on GitHub.

We are now considering switching permantently from Subversion to Git, meaning the Subversion repository will eventually be abandoned and only the Git official central repo will be kept up to date.
Before making such move we'd like to hear from the users community, please take one minute to share your opinion about the switch to Git:
