Where it all begins.

Proximity to the Trail

How close to the trail am I? This tends to be a common question whether you're on the trail or sitting at home binge watching your favorite series while self isolating.

Here are several ways you can answer that question regardless of your tech-saviness.

Postholer Google Trail Maps
This is by far the easiest way to find your proximity to the trail, and you have access to a fully interactive map in the process. This requires a device with location services enabled, like a smartphone (Hint: a desktop PC may not work well). Here's how:

Create a .PNG/.JPG Image
You can create a static image with tons of additional info to suit your taste. This requires a bit of tech-saviness. We'll use Project GIS for this.

So, here's what we have so far:

As a proper URI (no spaces or new lines), it will look like this:,trace,mileMarker,findNearest&trail_id=3&t_srs=EPSG:900913&bbox=-126,24,-66,50&lat=41.752832&lon=-124.194178&height=400

Plug that into your browser (or just click it) and you should see:

AT Proximity

Get it as CSV/JSON
Getting the information textually is almost identical to getting an image. Let's build the URI:

As you'll notice 'layers' was replaced by 'typename' and it should only have a single value. The full documention for WFS layers can be found in Project GIS.

The complete URI is:

Plug that into your browser (or just click it) and the resulting file should look like:

   "POINT (-84.198417 34.650986)","1",trail,"2150.5","3460.9","100",41.762278 -124.25157
   "POINT (-124.25157 41.762278)","2",location,"2150.5","3460.9","100",41.762278 -124.25157

The above is for CSV. To get JSON change outputformat to &outputformat=application/json
