A buffer I created successfully executed, but I received the following message in ArcGIS Desktop 10:

WARNING 000632: Datum conflict between map and output.

How can I fix this?

This isn't really a big deal, just a minor warning from ArcGIS. If you want it to go away, change the spatial reference for your data frame to match that of your output feature class. More info: 000632 : Datum conflict between map and output.

Docs on how to change your data frame's spatial reference: Specifying a coordinate system

  • From first link -- "layer is automatically transformed to the data frame's coordinate system." I interpret this to mean that my layer and data frame match up in the map display. Is this accurate? – Beth Dec 8 '10 at 0:39
  • Also: will I run into problems running intersect and union functions if the coordinate systems are off? – Beth Dec 8 '10 at 0:40
  • ArcGIS automatically reprojects data on the fly so that they can be displayed in the same coordinate system. The underlying data isn't actually transformed. – Derek Swingley Dec 8 '10 at 1:00
  • Best practice would be to make sure all your inputs for intersect, union, etc. are in the same coordinate system but ArcGIS will transform them on the fly. – Derek Swingley Dec 8 '10 at 1:01
  • Systematic testing in ArcView 9.1 uncovered loads of bugs in computing spatial relationships between polygon layers whenever they had an undefined coordinate system. Most of the bugs went away once a coordinate system was defined. I haven't checked whether those bugs have been fixed in subsequent releases. It's prudent to view all geoprocessing operations with suspicion. – whuber Dec 8 '10 at 5:03
