In addition to the generic FME feature attributes that FME Workbench adds to all features (see About Feature Type Attributes), this format adds the format-specific attributes described in this topic.
Geometry
The geometry of JSON features is 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_rectangle |
Simple rectangular polygon 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.
Boxes
json_type: json_rectangle
Features with their json_type set to json_rectangle are simple rectangular closed polygons. Features with this type will not have any interior boundaries.
Aggregates
json_type: json_collection
Features with their json_type set to json_collection are a heterogeneous collection of multiple geometries.
