I'm trying to create a simple evaluation within a script which does not restrict the spatial reference of the data, but the output is fixed: WGS 1983 Web Mercator Aux Sphere. All inputs will be projected data.
I want to project any input data to match the desired output projection, but I need to evaluate the datum of the input vs the output. .
Unfortunately, according to the documentation found here, this property (GCSName) is available only for geographic data. However:
Because a projected coordinate system is based on a geographic coordinate system, projected coordinate system properties can be accessed from a geographic coordinate system via the GCS property.
But the GCS property returns a spatial reference object for which I do not know how to format or parse parameters from to evaluate. Is there a way to do this? This will eventually be rolled-up into a script tool.
Any general tips on handling such a process would be greatly appreciated. I anticipate there will only be a handful of input PCS to deal with but it is entirely possible that there both NAD83 & WGS84 datums (3 feet matters for us in this case!).
