Question #: 59
Topic #: 5

An ArcGIS user is tasked with editing a layer containing a large number of features, using another layer that is in a different coordinate a system as reference. The user adds the layers in ArcMap and starts an edit session. A warning message about editing data in a different coordinate system is displayed.

What is the most efficient way to edit the data to avoid potential distortion in the data?

Achange the data frame's coordinate system to match the coordinate system of the layer being edited

Bproject the reference layer so the coordinate system matches with the one that needs to be edited

Cgeoreference the reference layer and start a new edit session

Dcreate a geodatabase topology with the two layers and add a rule so new data always snaps to thereference layer

Seriously, Talia? Topology for this? What is this, the 90s? Option B all the way, let's keep it simple.

Wait, what do you mean it's not option D? Topology is the way to go, no doubt about it. Snap that data right into place!

Ah, the good ol' coordinate system shuffle. I'm going to have to go with B here. Can't risk distorting the data, am I right?

Hmm, I was thinking option C, but then I remembered that georeferencing can be a real pain. I'll stick with option B, it seems like the most efficient way to handle this.

A) change the data frame's coordinate system to match the coordinate system of the layer being edited

I disagree, I believe projecting the reference layer to match the coordinate system of the layer being edited is more efficient.

Oh man, this is a tricky one! I'm going to go with option B - projecting the reference layer. That way, I don't have to change the data frame and risk messing up my other layers.
