Actual exam question for Esri's EADP19-001 exam

Question #: 69
Topic #: 4

An ArcGIS user is tasked with publishing an image service out of a collection of rectified satellite imagery. Building the Image service definition results In a rotated dataset with large areas of NoData on the comers. The ArcGIS user needs to recompute the footprints to remove the large areas of NoData on the edges. Which method of recomputing footprints accomplishes this?

Surprised it's not related geometry!

I thought radiometry might be the answer...

Wait, are we sure it's not by clipping?

I definitely remember that radiometry is more about the pixel values, so I don't think that's the right choice for fixing the NoData issue.

I’m a bit confused about the options. I feel like related geometry could be relevant, but I can't recall how it specifically applies to recomputing footprints.

I think we practiced a similar question in class, and I want to say that clipping might be the method to use here to handle those NoData edges.

I remember something about using geometry to recompute footprints, but I'm not entirely sure if that's the right approach for NoData areas.

This is a good one. I'm feeling pretty confident that the geometry option is the right approach. Gotta love those little tricks to clean up those pesky image service issues.

Ah, I think I've got it. Recomputing the footprints by geometry is the way to go here. That should help me trim off those unwanted edges and get a nice, clean image service. Time to mark that one down.

I'm a bit confused on the difference between the methods here. Geometry, radiometry, clipping - which one is going to give me the best result for removing those NoData corners? I'll have to review the concepts again.

Okay, let's see. Recomputing the footprints to remove the NoData areas - that sounds like it could be the key here. I'm leaning towards option A, but I'll double-check the others just to be sure.

Hmm, this seems like a tricky one. I'll need to think through the different options carefully.

Hmm, I'm torn between A and C. Geometry or clipping? Decisions, decisions. Maybe I'll just flip a coin and hope for the best. ArcGIS, the gift that keeps on giving!
