GeoJSON (Geographic JavaScript Object Notation) Feature Representation
In addition to the generic FME feature attributes that FME Workbench adds to all features (see About Feature Type Attributes), this format also adds format-specific attributes (Format Attributes).
Geometry
The geometry of GeoJSON features may be identified by the json_type attribute. The valid values for this attribute are:
json_type | Description |
---|---|
json_no_geom |
FME Feature with no geometry |
json_point |
Point feature |
json_line |
Linear feature |
json_polygon |
Simple polygon or donut feature |
json_collection |
Feature with multiple geometries |
No Geometry
json_type: json_no_geom
Features with their json_type attribute set to json_no_geom do not contain any geometry data.
Points
json_type: json_point
Features with their json_type set to json_point are single coordinate features or an aggregate of single points.
Lines
json_type: json_line
Features with their json_type set to json_line are polyline features or an aggregate of polylines.
Areas
json_type: json_polygon
Features with their json_type set to json_polygon are polygon features which may or may not have interior boundaries, or an aggregate of such polygons.
Aggregates
json_type: json_collection
Features with their json_type set to json_collection are a heterogeneous collection of multiple geometries.
