     In the late 1990's we received a large-scale update to all of our waterbodies and watercourses, covering some 55 NTS map sheets and an unremembered thousands number of features. We needed to keep the value added attributes of our old hydrology (lake names, surface elevation, etc.) and replace the geometry. The geometry of old and new were close enough that we could guarantee the centroids of each polygon would still be bounded by the new polygon boundaries. So:

    1. Data_Cov has the attributes we need in Arcinfo region subcoverages; the geometry is unwanted.
    2. Geometry_Cov has the geometry we need, but no attribute data.

    • Thebecause the geometry of Data_Cov is unwanted, so the Workstation commands UNION, INTERSECT, IDENTITY, INTERSECT will not work.
    • Therethere are too many records to transfer for the Workstation ArcEdit TRANSFER commaned to be feasible
    • ArcMap 'spatial join' was initially promising, but it ignores polygons which have non-coincident geometry.
    • Using the ArcMap 'spatial adjustment' tool is not suitable as it is interactive. (See this ESRI Forum thread: transferring attributes from one feature to another)
