How to translate WGS 84 to Equirectangular?

Sep 5, 2011 at 6:38 PM

I have a SqlGeogrpahy instance in my .Net application initialized to long, lat of 10,10. I wish to convert those to equirectangular planar coordinates.

SqlProjection.Equirectangular expects "longitude0" and "parallel" parameters. What do those parameters represent, and how to determine their values?
