I have no experience in mapping, so please excuse me if this sounds foolish.
I'm trying to use Microsoft MapPoint (2004) software to geocode a number of addresses in Excel. However, my version of MapPoint does not have a nice, neat way to return the latitude and longitude of an address; it has to be calculated.
The method I've found to calculate latitude and longitude, in a nutshell, uses the great-circle distances from the location to the North Pole and the prime meridian. These distances are calculated using spherical coordinates, so they're fairly accurate, but they're not as precise as I'd like.
Is there a way to tweak these, let's call them "spherical" coordinates, so that they better represent true "elliptical" coordinates?
