public class GeoJsonReader extends Object
Geometry
.
A specification of the GeoJson format can be found at the GeoJson web site: http://geojson.org/geojson-spec.html.
It is the caller's responsibility to ensure that the supplied
PrecisionModel
matches the precision of the incoming data. If a lower
precision for the data is required, a subsequent process must be run on the
data to reduce its precision.
Constructor and Description |
---|
GeoJsonReader()
The default constructor uses the SRID from the Geojson CRS and the
default
PrecisionModel to create a
GeometryFactory . |
GeoJsonReader(org.locationtech.jts.geom.GeometryFactory geometryFactory)
This constructor accepts a
GeometryFactory that is used
to create the output geometries and to override the GeoJson CRS. |
Modifier and Type | Method and Description |

Reads a GeoJson Geometry from a
Reader into a single
Geometry . |
org.locationtech.jts.geom.Geometry |
read(String json)
Reads a GeoJson Geometry from a String into a single
Geometry . |
