I received a DGN file, I believe created in Bentley 8, and there is a bit of a misalignment problem. The dgn, when overlain on a Bing Maps aerial or NAIP image, shows up about 20 m or so off. I'm set up in NAD83 State Plane 1601 Kentucky North and using ArcGIS 10.2.1 for Desktop.
It's important that these line up fairly close because this dgn will be used to create a regulatory boundary for field surveys.
So my question is, are the aerials correct and the DGN is just slightly off or vice versa? I assume the DGN is just slightly off. My initial inclination was to align the buildings in the dgn with the buildings in the aerial photograph and go from there. However, I started getting a little nervous that maybe that would end up putting one of the field workers off the mark.
