Syntax
Copy
public static bool AreIdentical(
	string projstring1,
	string projstring2
)

Parameters

projstring1
Type: SystemString
Specifies the full WKT map projection string to the first projection
projstring2
Type: SystemString
Specifies the full WKT map projection string to the second projection

Return Value

Type: Boolean
Examples
As an example, "UTM-32" is identical to "WGS_1984_UTM_Zone_32N", because they have the same set of parameters and the ellipsoids are equivalent, but the projections don't have the same name. Another example of identical map projections is "NAD_1983_StatePlane_Alaska_1_FIPS_5001" and "NAD_1983_StatePlane_Alaska_1_FIPS_5001_Feet". Some parameters are defined in different units, but they are converted to a common unit, before they are compared.
