distance static method
Calculates the simple planar (Euclidean) distance between two geometries.
This planar measurement uses 2D Cartesian mathematics to compute the distance. It is based upon the SpatialReference of the input geometries. If the input geometries do not use an 'distance preserving' spatial reference, the result can be inaccurate. You have two options available to calculate a more accurate result:
- Use a different spatial reference. Use the GeometryEngine.project method to project the geometry to a projected coordinate system that is better suited for area calculations. See Spatial references and Supported map projections for more information.
- Use the geodetic equivalent, GeometryEngine.distanceGeodetic.
Parameters:
geometry1— A geometry object.geometry2— Another geometry object.
Return Value: The distance between the two geometries in the same units as the geometry's spatial reference.
Implementation
static double distance(
{required Geometry geometry1, required Geometry geometry2}) {
_initializeArcGISEnvironmentIfNeeded();
return _withThrowingErrorHandler((errorHandler) {
return runtimecore.RT_GeometryEngine_distance(
geometry1._handle, geometry2._handle, errorHandler);
});
}
