New online national forest maps with trail mileages, road in

Postby Joseph » Sun Oct 20, 2013 5:40 pm

These online maps are now ready for almost all of the national forests in California, Oregon and Washington. Here are the links:
http://www.mappingsupport.com/p/gmap4_usfs_maps.html

Please read the Tips. There is a link to the tips in the upper left corner of each map.

To the best of my knowledge these are the only free online maps that show trail mileages without making you click anything.

They are also the only online maps that let you see the forest service roads that are open and roads that are closed by toggling those layers on and off.

Just replied over at BPL...

Looks very useful. I even see a couple of pretty obscure trails that I didn't think most knew about. Thanks again.
I'm still rather convinced that you can achieve more than you've ever dreamed of if you just lower your standards.

Thanks for the info and the link. I'm just starting to learn about the recreation available in the San Diego County portions of the Cleveland National Forest. This will help me get familiar with what's available in my new neck of the woods.

My earlier post claimed that the maps show data about open and closed forest service roads.
That data is no longer on the maps.

Yes, the data exists.
No, the forest service will not let me show it to you.

If you think this does not make a lot of sense, then I agree with you.

They are still classifying the roads, the data is not perfect, the big paper travel plan maps are the official maps, yadda yadda yadda.

Actually my sense is that at some unknown time in the future that open/closed road data will be 'blessed' by forest service management and made available for 3rd party software to display. But I have no idea when that will happen.

Nope. Free.

The forest service has two kinds of data that they place on GIS servers. One kind has been approved and is called "authoritative". That data is free and can be displayed by anyone with the right software and tech savvy. Gmap4 can display any of that data.

The other kind of GIS data the forest service has I will call 'draft' for lack of a better word. This data has *not* yet been deemed "authoritative". The open/closed road data is in this 'draft' pile. Their trail data is also in the 'draft' pile.

Last year I found out about the draft data. At that time the draft data was on a GIS server in such a manner that anyone could access it. I downloaded trail data for WA, OR and CA. Then public access to the draft data was shut off. But since I already had the trail data for those three states I was able to produce the forest service maps that are the subject of this thread.

Originally my maps displayed the open/closed road data by accessing that data right from the forest service servers as you looked at the online map. In other words, I never downloaded the road data. At some point I am assuming the forest service will decide the road data is good enough to be promoted to "authoritative" and then I can tweak my maps to display it.
