## Challenge #228: Know Your Boundaries

11 - Bolide

That was a fun one! Although I did nearly went down a rabbit hole...

here's my solution:

17 - Castor

So I had to hardcode some things and it doesn't feel like it runs fast, but here goes nothing...

Spatial fun! Really interesting to see the different ways this challenge was solved.

16 - Nebula

Another opportunity to practice the use of the spatial tools. Certainly there will be easier solutions.

I think I need to brush up on my spatial... As I was working out how to do this and got started down a route, I used a Batch Macro to feed in states that touched and got their border... so that I could combine them together. It wasn't until I was cutting the ends out that I realised i could have grouped the East and West states, not needing the Batch Macro... so I also did it without the Batch Macro afterwards... not sure which is neater. The Batch Macro did allow me to play with the buffer size easily though.

Using the spatial tools we will create an approximate Mississippi river! Find the challenge here: https://community.alteryx.com/t5/Weekly-Challenge/Challenge-228-Know-Your-Boundaries/td-p/616748
11 - Bolide

I pulled a sneaky move on this problem to fix it. Looking forward to finding a better solution to this.

7 - Meteor

Lots of new spatial operations to consider and sort out.
