Method Detail

buildGeometry

public static JGeometry buildGeometry(java.lang.String value)

Builds the jGeometry for the geojson

Parameters:

geometryValue - geoJson value for the geometry to convert

Returns:

jGeometry value for the received geojson

isJsonString

public static boolean isJsonString(java.lang.String toValidate)

Return true if the string is a JSON string, false otherwise.

Parameters:

toValidate - the string to validate

Returns:

true if the string is a JSON string, false otherwise

sameSRIDAndDim

public static boolean sameSRIDAndDim(JGeometry geom1,
                                     JGeometry geom2)

Return true if the geometries have the same SRID, false otherwise.

Parameters:

geom1 - first geometry

geom2 - second geometry

Returns:

true if the geometries have the same SRID, false otherwise

setTolerance

public static double setTolerance(java.math.BigDecimal inputTolerance,
                                  JGeometry geom)

Sets the tolerance to 0.05 for geodetic geometries by default

Parameters:

inputTolerance - tolerance to set, it may be null

geom - jGeometry object to verify if it is geodetic

Returns:

the configured tolerance
