Challenge #100: Find Ned!

Learnt quite a bit about spatial tools. Used idea from @patrick_digan 

The standard engine workflow runs about 1.5 minutes, with AMP switched on, the time is reduced to 22s.

Challenge #100. Packaged workbook was too big on inputs

This one was a tough one for me, lots of introduction and practical use of a handful of spatial tools I rarely use. I believe Ned to be hiding out at (-105.547821, 38.998532).

Here's my solution. I made a 1 km grid then took the max and min values for the latitude and longitude then brute forced it. Didn't take more than 30 or so attempts.

Congrats, you got within 108.1 meters of Ned. Look to the E

Sorry Ned lad - there was an attempt but no success

Also can't upload the file

Managed to get to 7.7 m within 40s - using the AMP engine.

Wondered just how many spatial tools I could use to complete this one! 
I created a (non overlapping) trade area of 15.5km around every road then cut this away from Colorado leaving only the areas furthest away from the roads. I then calculated the sqkm and identified the largest remaining area, splitting this into 5m grids and calculating the distance from the roads. I tweaked the trade area size to reduce the load on the grids so that I could increase the grid accuracy.

Brilliant challenge! Got it down to 18.6 metres and 9ish seconds with AMP engine.
