Challenge #27: Spatial Telco Coverage Smoothing

Alteryx Alumni (Retired)

The link to last week’s challenge (challenge #26) is HERE

This week’s challenge is a spatial use case to preprocess a spatial object for mapping.  The input file is a single complex polygon that represents a coverage area.

 

Use Case: A wireless telecommunications company wants to remove holes and splatter from their coverage area for simplified map display.   Splatter can be define as unnecessary pieces of the whole polygon.

 

Objective: Remove all splatter less than 2 square miles and holes from the coverage area.

 

This exercise can generate varying answers based on the configuration of the spatial tools used for the process. As a result the challenge does not contain an output. 

 

Have fun!

Very similar to @GeneR / @TaraM - just did things in a different order.

More or less the same solution as Tara & Sean.

I really enjoy the spatial challenges because I don't get to use these tools very often at work. This was my first time using the Poly-Split tool. I attempted to use the Buffer tool as well but ended up deciding it wasn't appropriate.  

 

Question - what is the best way to check my results with spatial challenges? Usually, I join my solution to the output file and then add a filter to check the fields are identical. Will that work here too? 

 

Here is my solution:

Good Learning Exercise. I've never used the poly-split before.
