you did not mention the directions. accuracy and precision? how accurate is the gps and what precision? Was the survey entered on a map set to a geo coordinate system that was good & correct for the vicinity of the properties? If you gps to within a meter is it close enough or do you need to be within a 1/4 inch?
If the polygons and points disagree by hundreds of feet that might be a projection issue. Could you share the projection information for both the polygon parcel and GPS point layers? You might also want to double check that both layers are in either feet or meters and that the projection is the same as the data frame's projection. -Josh
One approach would be to move and rotate the individual shapes manually to best match their GPS, then assess how messy the result is overall. If it is pretty darn good you could snap points together or even integrate it. Put it likely would be messy.
Yes, this is what I'm hoping to do. Move and rotate shapes individually to best match GPS points. So you're saying manually moving them is the thing to do. There is no tool that I can set multiple control points (i.e. match up GPS points taken at corners with their corresponding corners on the boundary polygon) and allow GIS to find the most accurate orientation? The Spatial Adjustment tool does this, but I can't find a way to tell it NOT to distort, enlarge or shrink the shapes. I only want them to move and rotate.
Thanks for your help.
