I have a question about the projections used in ArcGIS Online (AGO). For example, if I geocode a CSV file of four points what projection is this layer using in AGO? Then, for example, if I create a map note to calculate the area within these four points, what projection is being used? If it is web Mercator, how accurate is this measurement since area is not preserved in Mercator?
