GeoTools 10.6 Released



The GeoTools community is pleased to bring you GeoTools 10.6:
Artifacts are also available from our Maven repository.

This is our first GeoTools maintenance release offering an extra six months of the GeoTools 10 series. This six month windows provides a grace period allowing you schedule your upgrade to GeoTools 11 while still receiving bug fixes. For more information see Changing Tracks on the the GeoTools Release Train.


The GeoTools 10.6 Release Notes detail changes since 10.5. These include:
  • app-schema improvements handling nulls and undefined namespaces
  • SpatialLite supports now supports views in addition to tables
  • Oracle support continues to approve with better CRS axis name and spatial index support
  • Small fixes for GeoJSON, GeoTIFF, process annotations

 

About the GeoTools 10.x Series

Summary of the features for the GeoTools 10.x series:
  • Structured grid coverage readers allow raster data sources that publish composite data products to expose individual rasters (ie granules) for processing, while still providing a seamless experience for rendering. The mosaic and NetCDF modules are the first ones to implement these new interfaces.
  • Efficient support for multiple coverages in GridCoverageReader provides ad-hoc access to raster formats that publish more that one data product. A image mosaic made of NetCDF granules and single file NetCDF sources are the first implementors of these new capabilities
  • new implementation of Shapefile DataStore (based on ContentDataStore superclass). This upgrade should be seamless for all users using DataStoreFactoryFinder. If you explicitly made use of the ShapefileDataStore or IndexedShapefileDataStore class please check the upgrade instructions.
  • The transform module graduated to supported status, providing a seamless way to rename, retype and hide SimpleFeatureSource attributes, as well as creating new ones based on OGC Expression
  • Additional OGC modules for the WCS 2.0 and WCS 2.0 EO models as well as adding XML parsers and encoders
  • Support for fills made with randomized symbols
The 10.x series features a number of research and development activities:
  • NetCDF has been updated to take advantage of the new coverage API introduced above
  • GeoPackage: a sample implementation of the geopackage spec that is currently being developed by the OGC
If you are interested in helping out please introduce yourself on geotools-devel mailing list.

Enjoy,

GeoTools 11.0 released

The GeoTools community is delighted to bring you the latest  GeoTools 11.0 download:
This release is also available from our maven repository.

This release is made in conjunction with GeoServer 2.5.

About GeoTools 11.0

Thanks to everyone who helped by testing the RCs. This is the first GeoTools release on the new release schedule, so the next planned release for 11.1 will be in May and then releases will follow every two months. This should help projects keep up with the frenetic pace of development in the future. It also reflects the increased the maturity of the GeoTools code base.

Summary of the new features for the GeoTools 11.0 series:
  • The DataStore API has a new removeSchema method to drop feature types. This new optional feature is currently implemented by the JDBCDataStore family (all spatial database backed stores), other stores will likely throw an UnsupportedOperationException
  • JDBCDataStore now exposes facilities to list, create and destroy indexes on database columns.
  • Ability to create and drop databases from the PostgisNGFactory
  • PostGis data store will now call ST_Simplify when the GEOMETRY_SIMPLIFICATION hint is provided, significantly speeding up loading of complex geometries  (the renderer can perform scale based simplification already, but doing it before sending the data speeds up data retrieval significantly)
  • ImageMosaic can now manage vector footprints for its granules, allowing to filter out no-data or corrupted sections of the imagery
  • All properties in a SLD style can now have a local unit of measure, as opposed to specifying the unit of measure per symbolizer. For example, if you need to have a line width to be 10 meters, its value can now be "10m"
  • Improved handling of data with 3D coordinates in JDBC data stores
  • A number of small improvements to the rendering engine, such as improved raster icon placement resulting in cleaner, less blurry output, improved label grouping, better handling of icons at the border of the map and in general much improved estimation of the buffer area needed to include all symbols in a map (for features that sit outside the map, but whose symbols are big enough to enter it).

New Features

  • [GEOT-2333] - Implement removeSchema in JDBCDataStore
  • [GEOT-4611] - SVG lineargradients to ColorMap generator
  • [GEOT-4640] - Add delete support to StructuredGridCoverage2DReader
  • [GEOT-4660] - Allow database creation/drop from the postgis factory params
  • [GEOT-4663] - Add geometry simplification hint support to PostGIS store
  • [GEOT-4683] - no binding for GML.CompositeCurveType

Improvement

  • [GEOT-4713] - Add support for citext data in the postgis data store
  • [GEOT-4714] - Allow normal sqlite and spatialite sqlite jdbc drivers to co-exist
  • [GEOT-4717] - Have WFS 2.0 collection binding encode a valid numberMatched regardless of the field contents
  • [GEOT-4652] - Add ogr GeoRSS unit test
  • [GEOT-4653] - Add SQLite support to OGR module
  • [GEOT-4654] - Add tests for various ogr formats
  • [GEOT-4655] - Use environmental variables to make testing OGR module easier
  • [GEOT-4680] - PostPreProcessFilterSplittingVisitor throws Exception with complex logic filter with null literals
  • [GEOT-4681] - SimplifyingFilterVisitor should eliminate constant binary comparisons
  • [GEOT-4702] - Try harder to do numeric comparisons when the target property type is also a number
  • [GEOT-4708] - Improve GRIB support on NetCDF modules
  • [GEOT-4738] - Add ability to disable PostGIS ST_Simplify usage
  • [GEOT-3472] - Add a higher precision alternative to getGeodeticCurve
  • [GEOT-4132] - Oracle GeometryConverter rectangle test is slow and non-robust
  • [GEOT-4163] - Make dimension a first class information (like srid) in JDBC data stores
  • [GEOT-4356] - Add JDBC4 support to JDBC-Oracle
  • [GEOT-4421] - Allow creation, list and removal of Indexes for JDBC DataStores
  • [GEOT-4531] - Borehole 1D support
  • [GEOT-4573] - Improve footprint management
  • [GEOT-4574] - Improve artifacts filtering operation
  • [GEOT-4575] - Improve requested resolution computation
  • [GEOT-4576] - Allows the crop operation to force internally using a mosaic operation when requested by param
  • [GEOT-4591] - Allow image mosaic to load footprints from per granule shapefiles
  • [GEOT-4593] - Allows configuring an empty ImageMosaic (no Granules) for future harvesting. (REST)
  • [GEOT-4603] - Add configuration to add or remove bbox from WFS 2.0 (GML32) responses in gt-xsd-wfs
  • [GEOT-4610] - GDAL PAM statistics on granules and mosaic statistic properties
  • [GEOT-4614] - Support per property uom in styling
  • [GEOT-4618] - Update to ImageIO-Ext 1.1.8
  • [GEOT-4647] - Use the simpler/faster "TOP N" syntax when limiting results from SQL Server
  • [GEOT-4665] - Add support for MVCC connection param
  • [GEOT-4669] - Allow the mosaic name to be specified via indexer.properties
  • [GEOT-4670] - Handle constant sizes that are results of function calls in MetaBufferEstimator
and too many bug fixes to mention here but see the jira ticket of anything that you are interested in.

Changing tracks on the GeoTools release train

The GeoTools release train has been burning through the stations and setting a rapid pace.

This activity marks a great deal of research and development, and a track record of consistent planned delivery. The turn around time for stable releases is also an important measure for getting fixes out to developers. Everything thing looks great right?

Holding on for the Ride

There is a downside to this rapid pace. In February I had a chance to do a roll call of LocationTech projects using GeoTools. Here is what I found:

- GeoGit uses GeoTools 9.0
- GeoMesa uses GeoTools 9.5
- GeoScript python uses GeoTools 9.0
- GeoScript Java Script uses GeoTools 9.0
- GeoScript Scala uses GeoTools 9.3
- GeoScript Groovy uses GeoTools 11-SNAPSHOT
- GeoTrellis uses GeoTools 9.5
- uDig uses GeoTools 9.0-M1

Not only were these projects not using the latest they were back on GeoTools 9 series (which had reached its "End-of-Life" in August 2013).

The release train was proving too exciting and many projects had simply fallen off.

Switching Gears

In discussions on the developer email list it gradually came out that there was a tension between having access prompt access to a release (wonderful when you are waiting for a fix) and the testing burden associated with upgrading (falling off the ride).

From an RnD standpoint the 6 month cycle is working out well. GeoTools needed a way to hold on to stable releases longer without over taxing the developer community.

Here is the resulting change proposal: Extended Release Schedule
  1. Drop back to releasing every other month
  2. Extend the release schedule with a 6 month maintenance phase
This proposal has now been accepted. Both the GeoTools and GeoServer release schedule will be effected.

Planning GeoTools 11

GeoTools 11 is scheduled for release in March, and will see a release every second month as we alternate between stable and maintenance branches.
  • GeoTools 11.0: March 2014 (Stable)
  • GeoTools 11.1: May 2014
  • GeoTools 11.2: July 2014
  • GeoTools 11.3: October 2014 (Maintenance)
  • GeoTools 11.4: December 2014
  • GeoTools 11.5: February 2015
Additional point releases may of course be added at the bequest of a development team. If you fall in a gap between releases don't be afraid to speak up.

Planning GeoTools 10

GeoTools 10 will no longer be retired in March, and is now extended with additional 6 months of life as a "maintenance" branch.
  • GeoTools 10.5: Feb 2014 (Stable)
  • GeoTools 10.6: April 2014 (Maintenance)
  • GeoTools 10.7: June 2014
  • GeoTools 10.8: August 2014

GeoTools 11-RC1 Released

The GeoTools community overjoyed to bring you the latest GeoTools 11-RC1 download:
This release is also available from our maven repository.

This release is made in conjunction with GeoServer 2.5-RC1.

About GeoTools 11-RC1

Thanks to everyone who help test the beta, GeoTools 11.0 is on track for release March 18th. If you have not yet had a chance to perform integration testing with please do so now with 11-RC1 to prevent surprises.

This release candidate hosts a great number of hardening fixes. Filter expressions now do a better job of comparing literals and comparing numbers. Importantly null handling is now consistent between local GeoTools Filters and those performed using SQL.

NetCDF support continues to improve, as does GeoPackage support. OGR support is now working for OSX. For anyone having trouble with multi-line labels SLDTransform is now better at using CDATA to preserve whitespace.
