Calculates area and perimeter length for each polygon in the input array.
GetAreasAndLengths(SpatialReference SpatialReference, Polygon[] InPolygonArray, out double[] Lengths)
|
Parameter |
Description |
|
SpatialReference |
SpatialReference of the geometries in the InPolygonArray.
Cannot be null. |
|
InPolygonArray |
The array of Polygons on which area and boundary
length will be calculated (on each Polygon). All geometries are assumed
to be in the coordinate system defined by the input SpatialReference. |
|
Lengths |
A double[] containing the boundary length (perimeter)
for each Polygon in the input array. The variable
is populated with the method is called. |
Return Value
A double[] containing the area for each Polygon in the input array.
Remarks
The area and length values are computed in
the units of the input spatial reference. It
is not recommended that this method be used on geometries associated with
a geographic coordinate system, since the length would then be calculated
in units of "degrees" and the area would be calculated in units
of "square degrees".
