Jeff,
I can’t say that I have seen these values in Stateplane. All of the StatePlane Systems that I am aware of have significant False Easting and Northing Values.
In my opinion, It is difficult to match a correct projection to spatial data if you don’t have a great sense of where the points should land.
If you decide to give it a shot, heres what I would do. Add ESRI Basemap to your map containing the shapefile/layer, and change projections in arcmap using View/Dataframe Properties. Keep trying different projections until you find one that works.
It’s the easiest way I know.

Subject: Points of Origin
Have any of you come across a geodatabase or shapefile containing points of origin for State Plane projections? In other words, points drawn at 0,0 in State Plane MA feet; 0,0 in State Plane NH feet; 0,0 in State Plane Maine East feet etc.
I am looking at some data of unknown projection and the usual suspects aren’t working out. I have a feeling someone accidentally drew these features in a projection for some incorrect state… It occurs to me that if I could measure a point in the data to points of origin, I could see which one lined up and thereby figure out the correct projection.
I know how to do this manually, but an existing point layer would save me some time of not having to try projections out one at a time.
Thanks in advance!
