- Simple BBOX filtering is based on backend OGCFeat service BBOX filtering
- Complex filtering is implemented as backend OGCFeat service BBOX filtering with post processing via FilteringFeatureReader in gs-ogcfeat-datastore
- Projection support is based on backend OGCFeat service CRS support
- Supports next link paging and limiting of page size and page count
Requirements for backend OGCFeat service
- Backend OGCFeat service must support Landing page, conformance,collections,schema for this extension to work properly
- OGC API - Features - Part 1: Core
- OGC API - Features - Part 2: Coordinate Reference Systems by Reference
- OGC API - Features - Part 3: Filtering and Common Query Language (CQL2)
- OGC API - Features - Part 5: Schemas - draft partial Schema support for collections is required
Issues and Todos
- (x) Fix: Storing a Basic Auth authorized backend fails in outer Geoserver code? -- landing page, /conformance /collections schema etc work just fine after
- (x) Todo: Confirm compatibility with Geoserver AXIS ORDER and reprojections
- (/) Done: refactor to org.geotools.api interfaces and https://github.com/geotools/geotools/wiki/Remove-OpenGIS
- (x) Partial: JDK17+ and other compatibility issues https://github.com/geoserver/geoserver/wiki/Jakarta-EE -- github actions builds for JDK17, JDK21
Installation
- Copy target/gs-ogcfeat-datastore-2.24.2.jar and swagger-models-2.2.16.jar to geoserver/WEB-INF/lib
Usage
- add an OGCFeat datastore and publish layers as usual
- Datastore URL is the OGCFeat service landing page
