hi, nice tutorial, but i have a problem. First calculation of surface area of Goa that you do and get result 3685, which looks good but fast look trough wikipedia shows that area of goa is 3,702 km². Iam trying to do this metod on bigger area and then ofc i get bigger error... I do the area calculations in arcGis and get same result as wikipedia. Why is this metod giving smaller area size, and how to do it correctly?
