Esri EADP19-001 Exam - Topic 2 Question 1 Discussion

Actual exam question for Esri's EADP19-001 exam

Question #: 1
Topic #: 2

Refer to the exhibit.

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 55 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.

An ArcGIS user is asked to calculate the distance a cruise ship will travel through open water, departing from Nome, Alaska, with stops at Point Barrow Alaska Churchill Manitoba St John's Newfoundland and ending in Bar Harbor Maine. On the basis of these calculations the cruise ship line will determine fuel requirements and travel time.

Which map projection yields the most accurate results for this distance calculation?

AAlbers equal area conic

BLambert azimuthal

CMercator

Dazimuthal equidistant

Definitely Lambert azimuthal for this scenario!

Azimuthal equidistant is great for measuring distances too.

Surprised to see Albers mentioned, thought it was all about Mercator!

I disagree, Mercator is more commonly used for navigation.

The Lambert azimuthal projection is best for distance calculations!

I have a vague memory that the Albers equal area conic is more about area preservation, so I’m leaning towards the Lambert azimuthal for this distance calculation.

I practiced a similar question where we had to choose projections for distance, and I think Mercator was mentioned, but I don’t recall it being the most accurate for this type of analysis.

I'm not entirely sure, but I feel like the azimuthal equidistant projection could also be a good choice since it preserves distances from the center point.

I remember studying map projections, and I think the Lambert azimuthal projection might be the best for distance calculations, especially over large areas.

Hmm, this seems like a tricky BGP configuration question. I'll need to carefully read through the topology and requirements to understand the different paths and how the BGP attributes can be used to influence the traffic flow.

I'm a bit confused by the wording of this question. Could someone explain the differences between the implementation methods a bit more? I want to make sure I understand the concepts before answering.
