Esri EADP19-001 Exam - Topic 6 Question 53 Discussion

Actual exam question for Esri's EADP19-001 exam

Question #: 53
Topic #: 6

The ArcGIS user is given data for the Arctic and is asked to perform various types of analysis using the dat

a. The data extends from the North Pole south to 70 degrees North Latitude Data layers may contain points lines, or polygons, and include ice surveys from NOAA depth contours: continental margins, locations of known and suspected oil reserves, endangered species habitat, and territorial boundaries for nations having Arctic coastline.

Which map projection should be used for the data to allow the most accurate buffering of those areas, in order to comply with the U.S court decision that ships may not approach closer than 20 nautical miles to a seal rookery?

Aazimuthai equidistant

Bpolar stereographic

Cgnomonic

DLambert azimuthal

Definitely not azimuthal equidistant for this case.

Gnomonic? Really? That seems off.

I think Lambert azimuthal could work too.

Polar stereographic is the best for Arctic data.

I recall that gnomonic projections show great circles as straight lines, which could be useful, but I’m not sure if it’s the best choice for buffering in this case.

I practiced a question similar to this, and I think the Lambert azimuthal projection was mentioned as good for area and distance preservation, but I’m not confident.

I’m not entirely sure, but I feel like the azimuthal equidistant projection could also work well for measuring distances accurately, especially for the 20 nautical miles rule.

I remember discussing map projections in class, and I think the polar stereographic might be best for Arctic data since it focuses on the poles.

Okay, I think the polar stereographic projection is the way to go here. It's designed for high-latitude regions like the Arctic, and it preserves distances and areas, which is exactly what we need for accurately buffering those seal rookeries.

I'm a bit confused on the differences between the azimuthal equidistant, polar stereographic, and Lambert azimuthal projections. I'll need to review my notes on map projections to make sure I understand the strengths and weaknesses of each one.

Hmm, this seems like a tricky one. I'll need to think carefully about the different map projections and which one would be best for accurately buffering the seal rookeries.

The key here is to use a projection that preserves distances and areas, since we need to accurately buffer the 20 nautical mile zones around the rookeries. I'm leaning towards the polar stereographic projection, but I'll double-check the properties of the other options.

Hmm, this seems like a straightforward question about user management in IBM Netezza. I'll need to think carefully about the different administrative privileges required.

Polar stereographic, hands down. It's the projection of choice for the Arctic, and I'm not about to risk getting sued over a seal-related incident. Those guys are serious about their personal space!

I'm going with polar stereographic. It just makes sense for the Arctic, and I don't want to get too close to those seal rookeries. I hear the seals have a pretty good legal team!

Lambert azimuthal? Sounds like a fancy French projection, but I don't know if it's the best fit for this task. Gotta love those tricky map projections!

Yeah, Lambert azimuthal does sound fancy, but polar stereographic seems like the most suitable option here.

Hmm, I'm not sure. Maybe I should consult the ArcGIS user manual before making a decision. I don't want to get this wrong and end up in hot water with the court!
