I spent about 30 minutes searching various menus, reading the manual and searching the web. Sorry if I should have found the answer.
I have two layers that are representing the same physical objects, stone monuments for my town's boundaries: One is from MassGIS is derived from 1890s surveys (and contains all town corners, not just my town). One is my own observations with RTK. I have a name field in my layer that should match a name field in the MassGIS layer. Obviously the coordinates do not quite match, but they are remarkably close (usually sub-meter). I saw visualizations in NGS's report about NAD83(2011) showing changes in station coordinates as the result of an adjustment, with a vector at each point showing the delta as distance/azimuth. So, I'd like to: create a new layer which is the point-wise vector difference of the input layers, with an output point in cases where the same name appears in both, with coordinates of one or the other and an attribute of distance/azimuth of the difference display that symbolized with a vector at each point and perhaps more analysis later, but that's my first goal. Pointers would be much appreciated. Greg
