MarkLogic 9 Product Documentationgeojson:to-geojson
geojson:to-geojson( $regions as cts:region* ) as object-node()*
Summary
Convert cts:region values into GeoJSON object nodes.
| Parameters | |
|---|---|
| regions |
Zero or more cts:region values to convert to GeoJSON.
|
Usage Notes
The GeoJSON Point node includes additional information that is not retained in the cts:point value. In particular, the altitude part of the point value will be dropped. Therefore two GeoJSON points at the same latitude and longitude with different altitude will nevertheless have equal cts:point values.See Also
