What you need to draw your map from aerial photography

Home PC with Windows XP or Vista
WMC Map software
Ortho-corrected aerial photograph (available from most aerial photography companies, New Zealand ortho-photos available from us)

To draw your farm map from an aerial photograph, you will need WMC Map farm mapping software and a digital orhto-corrected aerial photograph. WMC Map requires that the photograph is georeferenced so that you get an accurate farm map. A georeferenced ortho-corrected aerial photograph is a photo that has had any distortions from lens angles, altitude changes, etc, removed. It also lines up with GPS points automatically, which is how WMC Map calculates areas and distances, and means the map you create will be future-compatible in case you wish to import or export GPS points into or from the map.
