Hi I have a question about data display or placement in ArcGIS Map Documents!!
In Data Frame Properties it is possible to define both the Map Units and Display Units to inches, points, feet, yards, miles, Nautical Miles, millimeters, centimeters, meters, kilometers, decimal degrees, and decimeters. Is it possible to define the units as pixels?
So say you were tracking WHERE someone clicked on an image and this data is recorded in pixels away from an origin defined as the upper left corner of the image.
How can I make my points overlay correctly on my image? Would I somehow define Map Units to be "pixels" then georeference the image's upper left corner to be (0,0)? How would I do this?
