Esri EADP19-001 Exam - Topic 9 Question 16 Discussion

Actual exam question for Esri's EADP19-001 exam

Question #: 16
Topic #: 9

An ArcGIS user wants to create a tool that reads a Web data source from the U.S. Geological Survey site and create a feature class of earthquakes over magnitude 1 that have occurred in the last seven days. The data source URL is a .txt file directly usable as x, v event data, once downloaded.

The goal is to have a repeatable process to be run on demand overwriting the output each time with minimal user input and easy to understand for other users to whom the tool is provided

What should the user do to read and process the data?

Ause a third party scraping application to copy the data to a local file and read it as an x, y event data source

Bmanually copy the file to local disk before running and run the Make XY Event Layer tool

Cwrite a NET component that reads the data presents the data to ArcObjects as an x.v event and creates new features from the data source

DWrite a Python script that imports urllib reads the data with uriopen and read methods and creates features from the data stream

C sounds complicated, why not keep it simple?

Wait, can a Python script really handle that data stream?

A seems risky, scraping can lead to issues.

I think B is too manual for a repeatable process.

Option D sounds like the best choice for automation!

Writing a NET component sounds advanced, and I don't recall us covering that in detail, so I’m leaning towards option D as the best choice.

I feel like manually copying the file isn't efficient for a repeatable process, so option B seems less ideal.

I'm not entirely sure, but I think using a third-party scraping tool might complicate things unnecessarily.

I remember we discussed using Python scripts for data processing in our last practice session, so option D sounds familiar.

Option A seems really risky to me. Sending a weaponized file to employees could cause serious problems, even if it's just for testing. I'd be worried about accidentally infecting someone's machine.

Okay, I've got a strategy for this. I'll focus on the ethical considerations and potential risks of the approach described. Gotta be thorough on this one.

I'm pretty sure the Plan stage has 4 steps, so I'll go with option A.
