Geometry service GetAreasAndLengthsPreserveShape method
The GetAreasAndLengthsPreserveShape method calculates area and perimeter for each input polygon while preserving its shape.
SpatialReference of the geometries in InPolygonArray. Cannot be null.
The array of polygons for which area and boundary length will be calculated. All geometries are assumed to be in the coordinate system defined by SpatialReference.
Output lengths are expressed in this unit of measure (optional).
Output areas are expressed in this (squared) unit of measure (optional).
A double containing the boundary length (perimeter) for each polygon in the input array. The variable is populated when the method is called.
A double containing the area for each polygon in the input array.
The GetAreasAndLengthsPreserveShape method preserves the shape of each input geometry as it appears in its coordinate system and calculates the area or length of the geometry on the surface of the Earth.
The returned areas and lengths are expressed in the specified area units and linear units, if present, or in the units of the spatial reference. If AreaUnit and LengthUnit are not specified and the input spatial reference is a geographic coordinate system, then the lengths and areas are expressed in meters.
The spatial reference can be a projected or a geographic coordinate system. If the former, then each geometry is inverse projected into its associated geographic coordinate system before the distance calculations are performed.
