Esri Exam EADP19-001 Topic 8 Question 41 Discussion

Actual exam question for Esri's EADP19-001 exam

Question #: 41
Topic #: 8

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

That could work too, but it might involve more steps compared to just changing the data frame's coordinate system.

I would go with option B, projecting the reference layer to match the coordinate system of the layer being edited.

That sounds like a logical approach. It would ensure that there's no distortion in the data.

I think the best way is to change the data frame's coordinate system to match the layer being edited.

Creating a geodatabase topology with a rule for snapping to the reference layer sounds like a good solution to me.

I think georeferencing the layer and starting a new edit session is the way to go, it ensures accuracy in the data.

I disagree, I believe option B is more efficient because it directly addresses the issue of different coordinate systems.

I think option A is the best way to edit the data without distorting it.

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

Yeah, I was thinking the same thing. And what if the projection isn't perfect? Then we could still end up with distortion.

Hmm, I'm not so sure about that. Wouldn't that just be creating a whole new layer? Seems like a lot of extra work.

Okay, let's think this through. The key is that we need to make sure the data doesn't get distorted, right? So we need to match the coordinate systems somehow.

Yeah, I agree. Coordinate systems always trip me up. But let's see what we can come up with here.

Ugh, another coordinate system question? I thought we were done with those after the last exam. This is going to be a tricky one for sure.
