Challenge #100: Find Ned!

10 - Fireball

Dropbox is blocked at my company as other companies like mine source code should never be stored on external sites. Can you place the data files on https://github.com/alteryx as GitHub is not blocked for me?

Finally got mine tidied up and working... pleasantly close to Ned (0.4 m) run time 1m 16s


Congrats, you got within 0.4 meters of Ned. Look to the NE

Got to within 17.1 meters of Ned in 14 seconds

Since the input files are large I only included the workflow.  Found him within 2.2 meters!


Ran in 5:59 on my computer, but the weekly virus scan is running at the same time so it may have been competing for resources.

@darryl5280, I'll see what we can do!  I'll post back when I have an update!

I considered another iteration, but 0.3m in 2 minutes will do!

Okay, I've never done spatial analysis before so this challenge was quite difficult for me. After hours of hopelessly wondering in the Colorado outback I decided to get some help and was inspired by @LordNeilLord 's solution. Anyways, learned a lot about the spatial tools and think this was a fun excercise!

So I think we need to organize an expedition to this spot next summer.  It looks like its about 16 miles hiking from the nearest trail head (one way), so its probably at least 2 days round trip.  I think I've found the best route:




Who's in?

Or maybe I found a better route.  Hard to measure distance because google doesn't have the trails. 


Starting from the south:  https://www.hikingproject.com/trail/7032122/pine-river-trail-523


Probably a similar distance, but less vertical.

This one was a fun exploration of the spatial tools. After many different attempts and approaches, landed on using grids of shrinking sizes. Rinse and repeat the gridding process, finding the one furthest from the roads.

I wanted to embed the "How Close is Ned" app into my workflow, and create an iterative macro that would loop until the workflow gets you to under 1 km away, but couldn't figure out 1) how to call the app, and 2) how to get the results written to a format that can be used for comparison. Would love suggestions & feedback here!

25.1 seconds is very reasonable to get within 3 m.
