Features

GeoServer is a high-performance web service for the publication of spatial information.

GeoServer Enterprise is a commercial distribution of GeoServer offering long-term-support and extended support options for GeoCat customers. GeoCat is a proudly open source company working as a member of the GeoServer community.

If you have used earlier versions of GeoServer Enterprise review the current release notes </welcome/index> for an overview of significant changes in this version.

Web Services

GeoServer Enterprise publishes your information using a selection of open standards and industry standards.

GeoServer Enterprise:

• Web Map Service (WMS)

  Shares information visually as cartographic data products generated from geospatial data and styling.

• Web Feature Service (WFS)

  Publish vector information as geographic features for use in Desktop GIS, Web Mapping and Processing and Analysis.

• Web Coverage Service (WCS)

  Access raster information as a geographic coverage, generating and data products for analysis, processing and visualization.

• WMTS / TMS / WMS-C

  Integrated GeoWebCache supports a range of tileset based protocols for mobile and web mapping applications.

GeoServer extensions:

• Web Processing Service (WPS)

  Publishing of geospatial processes, algorithms, and calculations

• Catalog Services for the Web (CSW)

  Retrieving records describing data products published by GeoServer.

Layer Service Settings

Often requested functionality, define which services are enabled on a layer-by layer basis directly from the layer editor. Previously this functionality was only available from the data security page.

See Layer Service Settings.

EPSG database v 9.6

The EPSG database has been updated to version 9.6, including roughly a thousand more codes than the previous version available in GeoServer. The code has also been updated to ensure the NTv2 grid shift files between GDA94 and GDA2020 work properly. Sponsored by GeoScience Australia.

Web Map Service

WMS Nearest Match for time dimension

WMS time dimension can be configured for nearest match. This setting renders the nearest time to the one requested (either explicitly, or implicitly via the default time value).

• In case of mismatch the actual time used will be returned along with the response as a HTTP header.

• Functionality can be configured with a maximum tolerance, beyond that the server will throw a service exception.

Dynamic densification on reprojection

GeoServer has always reprojected data “point by point”, this typically caused long lines represented by just two points to be turn into straight lines, instead of curves, as they were supposed to.

There is a new “advanced projection handling” option in WMS enabling on the fly densification of data, the rendering engine computes how much deformation the projection applies in the area being rendered, and densifies the long lines before reprojection, resulting in eye pleasing curves in output. See a “before and after” comparison.

Reprojection, original point by point versus densified mode

Web Feature Service

Complex GeoJSON output changes

Improved GeoServer WFS generation of GeoJSON out of complex features data sources:

• The property/element alternation typical of GML is preserved, causing deeply nested data structures.

  To avoid writing container.x.x access to reach the x value, the output now skips one of the containers and exposes a direct container.x structure.

• XML attributes are now turned into plain JSON properties, and prefixed with a @

• Feature and data types are now preserved in translations, as a @feaureType and @dataType attributes

• Full nested features are encoded as GeoJSON again, keeping their identifiers

This work supports the use of app-schema compldex feature output. Sponsored by French geological survey – BRGM, and the French environmental information systems research center – INSIDE.

Web Map Tile Service

Tile protocols are provided by an emended GeoWebCache component.

Azure GeoWebCache blobstore

Tiles can now be stored in Azure blob containers, increasing GeoWebCache compatibility with cloud environments.

Note Azure does not provide, a mass blob delete API. On truncate GeoWebCache is required to individually remove tiles making a DELETE request for each one.

Web Processing Service

WPS Execution Management

WPS GetExecutions vendor operation to list the running processes:

• Users can review all their running processes

• Administrators can see all processes

WPS Dismiss vendor operation to cancel the execution of one of the listed processes.

See WPS Operations.

Style Editor helpers

Style editor usability improved with:

• Toolbar color picker to select a color and turn it into HEX specification

  

  Style helper color picker

• Toolbar file chooser to select an icon and build ExternalGraphic reference.

  

  Style helper external graphic

• Auto-complete suggestions for SLD 1.0.

  Use control-space for context aware suggestions.

RasterSymbolizer dynamic channel selection

A GeoServer extension to SLD supporting the use of expressions for SourceChannelName. This allows the dynamic channel selection, important for working with multispectral or hyperspectral data.

This approach avoids generating different styles for each false color combination.

Map algebra

The rendering engine now provides support for an efficient map algebra package knows as Jiffle.

Jiffle was produced by Michael Bedwards, and has now been upgraded to support Java 8, and integrated in jai-ext. Now available GeoTools gt-process-raster module the functionality can be used from either WPS or as a rendering transformation.

See Rendering Transformations.

SLD Service

The optional SLD Service extension is available for:

• The generation of classified maps of vector data based on criteria such as equal interval, quantiles and unique values.

• Vector data filtering based on standard deviation, equal area classification

• Raster processing with the generation of classified maps and data filtering.

• Raster processing makes use of automatic sub-sampling when the source image is too large.

The SLD REST Service is used to generate thematic styles based on attribute data:

curl -v -u admin:geoserver -XGET
  http://localhost:8080/geoserver/rest/sldservice/states/classify.xml
  ?attribute=PERSONS
  &ramp=CUSTOM
  &method=quantile
  &intervals=3
  &startColor=0xFF0000
  &endColor=0x0000FF
  &open=true

GDAL stores updated to GDAL 2.x

The GDAL image readers have been updated and now work against GDAL 2.x official binaries, without requiring custom builds.

Image mosaic highlights

Control the content shown to users:

• “virtual native resolution” read parameter to compose outputs using a native resolution. Used to advertise a reduced resolutions to users providing less detail than the native resolution on disk.

• read mask parameter to clip the image to a provided geometry, to provide users access to different areas of the image.

Improvements:

• Use multiple well-known-binary footprints for overviews masking

• NetCDF mosaic performance improved using auxiliary store config file to share a repository

• Mosaic can now handle wildcard EPSG:404000 CRS images allowing GeoServer to force the spatial reference system advertised

Additional cloud storage option:

• Support for remote images in S3 or Minio. This support requires the mosaic index to be created manually.

Database

GeoServer enterprise:

• PostGIS / JNDI

GeoServer extensions:

• Oracle / JNDI

GeoServer extension (premium):

• SQL Server / JNDI

PostGIS Geometry

PostGIS geometry handling for increased accuracy and performance:

• Read geometries with measures from PostGIS and encode the results in GML.

  GML does not natively support measures, so the encoding is off by default. Please ensure clients involved in WFS usage recognize this extra ordinate.

• TWKB encoding for geometries for all WMS/WMTS requests, reducing the amount of data travelling from the database to GeoServer.

  During WMS rendering the size of each pixel is used for on-the-fly simplification of Geometry. By making use of tiny well-known binary the amount of data is further reduced by sending over the first coordinate at high accuracy, and capturing the remaining coordinates using offsets.

Note that due to a limitation of the JDBC driver use of prepared statements is required for full binary transfer retaining accuracy. When not using prepared statements geometries are transfered using ASCII text.

PostGIS Filter Functions

Default changed to encode filter function into SQL:

• String functions: strConcat, strEndsWith, strStartsWith, strEqualsIgnoreCase, strIndexOf, strLength, strToLowerCase, strToUpperCase, strReplace, strSubstring, strSubstringStart, strTrim, strTrim2

• Math functions: abs, abs_2, abs_3, abs_4, ceil, floor

• Date functions: dateDifference

PostGIS Highlights

• Reading and writing the array data type, including native filtering (with index support, where feasible).

• SSL encryption control, the driver defaults to have it on with a significant overhead, if the communication is in a trusted network the encryption can be disabled with benefit to performance

• Improved encoding of OR filters, which now use the IN operator where possible, increasing the likeliness that an eventual index on that column will be used

• Native KNN nearest search when using the nearest filter function

System Requirements

Java 8 or Java 11

GeoServer Enterprise works with either Java 8 or Java 11. Tomcat 9 or newer is required for the WAR install.

The Java ecosystem is now being led by the open source OpenJDK project, with long term support available from a range of organizations notably RedHat OpenJDK and Adopt OpenJDK. The GeoTools user guide provides an overview of Java 8 and Java 11 distributions.

• Java ecosystem is now led by the open-source OpenJDK project

• Java 8 will continue to be available

• Organizations using Oracle JDK are encouraged to review options

Java 11 no longer supports the Java 2 extension mechanism used for native JAI and native ImageIO libraries. We recommend the use of the pure Java JAI-EXT operations which have been made the default.

JAI-EXT operations

This release of GeoServer Enterprise defaults to the use of JAI-EXT operations.

The JAI-EXT library offers a pure java implementation enhanced for geospatial functionality supporting NODATA pixels and support for vector footprints.
