Frequently Asked Questions: DFIRM Tools – General Questions

Why do I get a "Missing Projection Information" error when launching ArcMap?

Cannot set Spatial Reference for data frame. Please ensure that Study_Info is completely populated.

When ArcMap opens, the coordinate system for the data frame is set according to the Projection Zone field's domain value in the Study_Info table. If this field is empty or erroneously populated, the coordinate system cannot be set, and it will default to Geographic. Use GeoPop to correctly attribute this field, close your ArcMap session, and relaunch your step. When ArcMap opens, the error will have been resolved.
