[teiid-issues] [JBoss JIRA] (TEIID-3305) Add system functions for GeoJSON

Add system functions for GeoJSON -------------------------------- Key: TEIID-3305 URL: https://issues.jboss.org/browse/TEIID-3305 Project: Teiid Issue Type: Feature Request Components: Query Engine Reporter: Tom Arnold Assignee: Steven Hawkins Labels: spatial Add system functions to convert between GEOMETRY and GeoJSON. These will be helpful for sources that use GeoJSON (like MongoDB and RethinkDB). Conversion will be GeometryType (WKB) ↔ JTS Geometry ↔ GeoJSON. * https://github.com/bjornharrtell/jts2geojson * http://geojson.org/geojson-spec.html * http://wiki.geojson.org/GeoJSON_draft_version_5 I don't believe these are part of the OGC spec, but it would probably be best to implement them similar to PostGIS. * http://postgis.org/docs/ST_AsGeoJSON.html * http://postgis.org/docs/ST_GeomFromGeoJSON.html
