GeoServer 2.13-RC1 Released

We are happy to announce the release of GeoServer 2.13-RC1. Downloads are available (zip, war, and exe) along with docs and extensions.

This is a release candidate of GeoServer made in conjunction with GeoTools 19-RC1.

We want to encourage people to test the release thoroughly and report back any issue found. With no further delay, let’s see what’s new, that is, what is there to test!

Isolated Workspaces

The concept of an “Isolated Workspaces” has been added to GeoServer, to allow for reusing a namespace among multiple workspaces. In particular, an isolated workspace allows reuse of a namespace already used by another workspace, but its resources (layers, styles, etc …) can only be retrieved when using that workspace’s virtual services and will only show up in those virtual service capabilities documents.

When reusing a namespace among workspaces, exactly one of those must be non-isolated, and the rest must be isolated; i.e. isolated workspaces have no restrictions in namespaces usage but the existing restrictions still apply for non isolated workspaces.

This is particularly useful for those publishing complex schemas for INSPIRE compliance. For more details, refer to the original proposal.

GeoWebCache REST API

Two new endpoints have been added to the GeoWebCache REST API:

• /gwc/rest/blobstores:

  • GET /gwc/rest/blobstores for a list of the blobstores

  • GET /gwc/rest/blobstores/{blobStoreName} for details about a single blobstore

  • PUT /gwc/rest/blobstores/{blobStoreName} to create or update a blobstore

  • DELETE /gwc/rest/blobstores/{blobStoreName} to remove a blobstore

• /gwc/rest/gridsets:

  • GET /gwc/rest/gridsets for a list of the gridsets

  • GET /gwc/rest/gridsets/{gridSetName} for details about a single gridset

  • PUT /gwc/rest/gridsets/{gridSetName} to create or update a gridset

  • DELETE /gwc/rest/gridsets/{gridSetName} to remove a gridset

API docs for these endpoints will be added to the GeoServer documentation shortly. Until then, the request body syntax for PUT requests closely matched the equivalent structures in geowebcache.xml: BlobStores and GridSets.

The ArcGISCache backed layers are now also configurable via the REST API.

This release sees a major reworking of the configuration system in GeoWebCache that will allow for plugging in alternate configuration persistence mechanisms in future. While these changes should be largely invisible to users, it is a huge update that impacts all of GeoWebCache. However, due to these changes, we ask that you please test the embedded GeoWebCache.

UI Improvements

Entering in URLs for data files has been improved with autocomplete - now GeoServer will scan the path that has already been typed, and suggest existing files within that path.

In addition, autocomplete support has been added to a number of dropdowns which contain a long list of values, such as stores or layers. You can now start typing the name of an option, and the visible options will be filtered to match.

Editing raster layer parameters made easier, from a wall a text input fields, to appropriate controls being used depending on the parameter type. Here is a “before and after” comparison:

Finally, error messages are now displayed both at top (as usual) and bottom (new!) in all configuration pages. This should make it easier to locate error messages, especially while editing styles:

GeoPackage performance improvements

GeoPackage reading and rendering performance improved significantly, up to two times faster on large datasets full extractions and 50% faster on small bounding box searches, bringing GeoPackage on par with PostGIS. We also have a Google spreadsheet with more details.

Shapefile remains king of full dataset extractions and the fastest data source for pure spatial driven queries.

WFS 2.0 and WMTS 1.0 OGC compliance work

During the past few months we have been involved in OGC Testbed 14 and significantly improved GeoServer compliance with WFS 2.0 and WMTS 1.0. The work involved numerous fixes in GeoServer/GeoWebCache, along with variuos fixes in the CITE tests themselves. The changes were too numerous to backport to the 2.12.x series, so if compliance with these protocols is important it’s time to consider an upgrade to the 2.13.x series. For details see these lists:

• Full list of WFS 2.0 OGC compliances related changes

• List of changes for WMTS 1.0 are split among GeoWebCache and GeoServer ones

Work is still ongoing and a small number of issues are yet to be fixed, we’ll keep you updated.

Support for more PostGIS data types

The PostGIS data store now has simple support for HStore and JSON columns. HStore is returned as a Map and will render as a JSON formatted string field in common WFS output formats, while JSON is read as a string and rendered as-is. In both cases no special query support has been added for those types (but we’d be very happy if someone would work, or sponsor, that functionality too).

Better label position control in map rendering

When setting maxDisplacement on point/polygons the renderer used to search in a circular area around the designated label point. The new displacementMode vendor option allows to control the positioning by specifying the preferred cardinal positions, as a comma separated list.

Coverage views from heterogeneous bands

Satellite data often comes as a set of heterogeenous resolution bands, due to multiple sensors having different native resolutions. It is yet useful to have all bands packaged on the same coverage, for ease of display (false color setups) and information (GetFeatureInfo). Coverage views now allow to mix those bands, coming from separate files and organized in a image mosaic, in a single multiband coverage view, resampling on the fly with configurable target resolution policies.

Removed OS X installers

Due to lack of resources and interest, the OS X dmg installers are no longer being built. OS X users can still use the system-independent binary.

New community modules and improvements

The 2.13 series comes with a few new community modules, in particular:

• Do you want to generate GHRSST compliant outputs from GHRSST inputs? Try out the new GHRSST NetCDF output community module.

• The mongodb community module provides an easy-to-use wrapper around the Ge0Tools mongodb data store, allowing you to publish geospatial data stored in mongodb.

• There is also a new community module introducing NSG profiles for the WFS and WMTS services.

Existing community modules also got some love, in particular:

• The WPS download module now allows to download large maps, and also build animations, generating MP4 courtesy of jcodec library. Both processes can (and should!) be invoked asynchronously to better handle long generation times. Here is an example of animation output:

[video width=”768” height=”768” mp4=”/img/uploads/response.mp4”][/video]

• The WPS download process now also allows control of GeoTiff output structure (tiling, compression) in raw raster downloads, as well as downloading granules part of a heterogeneous mosaic in their native CRS and native resolution

• Various JDBCConfig and JDBCStore performance improvements, reducing the number of configuration database queries performed for each OGC request. Configuration queries are also consistently logged for further analysis

Note that community modules are not part of the release; instead you can find them in the nightly builds.

Other assorted improvements

• Async WPS does not report wrong output parameters

• GetFeatureInfo requires high clicking precision when the WMS “max buffer” setting is zero

• totalFeatures for WFS 2.0 request returns wrong count

• CoverageStore HTML REST representation points to a coverage named after the store (instead of its actual name)

• WPSDownload: per-granule resolution on target resolution

• GeoWebCache fails to compute sub-gridset bounds for layers whose native CRS is wrong/cannot be recognized

• Regression: GetLegendGraphics renderer lines thicker than they should

• Backup/restore reports completion too soon

Test, test, test!

Now that you know about all the goodies, please go, download and test your favourite ones. Let us know how it went!
