[Doc] Explain that the Measure Tool uses geodesic algorithms for measurements #12

Open zwaap opened 9 years ago

zwaap commented 9 years ago

The Measure Tool uses the API's geodesic calculation functionality to provide highly accurate measurements. This has been a source of confusion for some, as these measurements may differ from those provided by software that calculates measurements in the spatial reference of the data, which is often planar instead of geographic.

Added a new section to the measure tool topic that compares geodesic and Euclidean algorithms. Noted that measurement values may differ if using both of these methods and that the geodesic result is more accurate.
