GeoJsonReader

public GeoJsonReader()

The default constructor uses the SRID from the Geojson CRS and the default PrecisionModel to create a GeometryFactory. If there is no CRS specified then the default CRS is a geographic coordinate reference system, using the WGS84 datum, and with longitude and latitude units of decimal degrees (SRID = 4326)

GeoJsonReader

public GeoJsonReader(com.vividsolutions.jts.geom.GeometryFactory geometryFactory)

This constructor accepts a GeometryFactory that is used to create the output geometries and to override the GeoJson CRS.

参数:

geometryFactory - a GeometryFactory

方法详细资料

read

public com.vividsolutions.jts.geom.Geometry read(java.lang.String json)
                                          throws com.vividsolutions.jts.io.ParseException

Reads a GeoJson Geometry from a String into a single Geometry.

参数:

json - The GeoJson String to parse

返回:

the resulting JTS Geometry

抛出:

com.vividsolutions.jts.io.ParseException - throws a ParseException if the JSON string cannot be parsed

read

public com.vividsolutions.jts.geom.Geometry read(java.io.Reader reader)
                                          throws com.vividsolutions.jts.io.ParseException

Reads a GeoJson Geometry from a Reader into a single Geometry.

参数:

reader - The input source

返回:

The resulting JTS Geometry

抛出:

com.vividsolutions.jts.io.ParseException - throws a ParseException if the JSON string cannot be parsed
