geographic puzzle


Recommended Posts

Start with the USGS DLG files for the area of interest. Remove the neatlines and join the files together. Fix the polygons at the borders. (A DLG file contains topological graphics, so every closed area is represented in the file as a polygon.)

 

Now, for each polygon, compute the point inside the polygon that is furthest from any edge (doing this is left as an exercise for the reader.) Keep track of the maximum distance you've found so far and which point went with it, provided it meets your other criteria (inside the county, state, etc.) When you're done, you have your answer.

 

Computationally expensive, and the first step is rather ugly, but it'll work. There are probably better solutions.

DO an online search for the newspaper article about this. A couple of years ago "they" figured that the farthest point fromany roads in teh lower states was 16 miles from teh nearest road. I believe they included logging roads. Some places in Co, some in MT and some in WY were among the farthest. I didn't keep the article but I wish I had. I am pretty certain it was about 16 miles.

 

The furthest point from any road in the continental United States is located deep in the wilds of Yellowstone National Park's Thoroughfare Region.

Probably Idaho with the Frank Church wilderness area. But that's a guess.

 

You would need mapping software that can tell you what the centroid is...nevermind you don't want the centroid.

 

Danged if I know unless you take comments like "Nevada, Frank Church" and start looking at maps.

Wherever you go there you are.

You would also have to include in your definition whether you are counting remnants of roads which may no longer be used.

 

In the lower 48, Idaho has the largest "roadless" area on the map (designated wilderness). Catch is, a lot of that area had dirt roads (from mining, logging and ranching) that date back about 100 years or so. Some (few) of these roads were left open for recreational and/or administrative use. A few are left for access to or on private land (landlocked). And some of those are entirely landlocked (accessable only by small plane). For that matter - you have to specify whether a back country airstrip is counted as a road.

 

Anyway, as a practicle matter most of even *those* roads cannot be used as such for the general public - for various reasons (not maintained, restricted use, grandfathered for private use only, etc...)

 

With all that aside, given a definition that includes only roads and trails that may be traveled (motorized) by the general public - and regardless of what some other study may have said - I would start looking in central Idaho first.

Uh oh.. I tried my own link in that thread, and it seems Car and Driver has pulled its archive from the web.

 

In any case, the guys at Car and Driver wanted to know the exact thing you were asking. They told all about their journey in the article. The coordinates of the spot are in my referenced post.

You need to think outside the box.

 

My guess would be the Farralone Islands off the California coast (still part of the lower 48 and the North American land mass). The Channel Islands have a few old roads used for trails.

Thanks logscaler-the last 30 min I spent there were a lot of fun and very educational. Bring on Trebeck! icon_biggrin.gif

 

These changes in latitudes, changes in attitudes;

Nothing remains quite the same.

Through all of the islands and all of the highlands,

If we couldn't laugh we would all go insane
