comment My class using ogr to calculate distance is returning incorrect results away from the equator
Martin - I've looked at the page that you linked and can't see how to calculate the scale factor to arrive at the 0.68 you mention. Is there a lookup table somewhere or a simple means of calculating the SF?

comment Looking for Python module to do lat lon calculations
Thanks. What are the units that are used in your examples? Do I need to convert my lat/lon points to these units? Or do I need to inform ogr that I'll be providing lat/lon data and it will take care of it?
