I am a new user of Surfer plotting farm fields and features. I am contemplating to upgrade to Surfer 11, but before doing so, I need to establish whether I can calculate and display field areas in hectares from latitude-longitude inputs. In addition I want to display the scale in kilometers on the map. Is this posssible with Surfer 8, or with Surfer 11? Your help will be appreciated Johandev
