I remember reading an article a few years back about google maps. They basically took satellite photos and used them to make maps via computer program. That means canals, ditches, driveways, etc can show up as a road. They then starting sending out their cars to verify the roads really exist. Of course that's mainly been done in populated areas which means they are not so accurate out in the boonies where we like to ride.

The google car actually went by my house. Even a glimpse of my daughters car heading out can be seen. Not sure how I feel about being able to peer into my backyard from google but there's nothing amazing to be seen. Thankfully I wasn't feeding the horses in my pajamas like I often do.

Most of the USG quadrant maps are based on the surveys done in the 1970. So when you buy a paper map, You are bound to get obsolete mapping. The Forest Service and BLM have both gone on active campaigns since the 70's to close off roads. They have stopped maintaining trails due to budget constraints, which means the trails eventually get grown over.

Programs like National Geographic Topo are based on those quadrant maps. So they can be extremely outdated. Showing roads that existed in the 70's but are now gone.

At least with the Google maps that are built upon satelite photos, You can often see the road, trail or waterways. The maps are constantly being refreshed. Every year or so. I've watched the images of my horse pasture and seen the different colored trucks I've owned over the past 10 years show up each year as the maps are refreshed.

To a certain degree that's true: however, the latest USGS maps (or at least some of them) which you can download & view as .pdf files, have an aerial photo/satellite layer with resolution good enough to pick out individual trees.

While it's true that these have some inaccuracies as well, they're a lot better than what Google Maps (or any other on-line source I've seen) has to offer. The thing about Google &c is that they're just not interested in the non-urban world.

As for the Forest Service &c closing off roads, it's true that a number have been closed to vehicle travel, but they're still there, and good for hiking, biking, and horseback riding. There have also been new trails constructed (at least hereabouts) such as the Tahoe Rim Trail - which is about the only trail I've actually seen on Google Maps.

There are numerous old roads where they have come in with heavy equipment and literally ripped them up. The Forest Service had gotten tired of ATV going around the closed signs, So they made them totally impassable to any kind of wheeled vehicle. Built large berms and make sure trees were laid across the old track. Basically did everything they could to revert the old road back to nature.

They were even extremely difficult to ride a horse down after the track excavators got done tearing them up. With some chain saws cutting out the deadfall trees and 10-12 winters of erosion to smooth out the hills and berms, we can get the horses down them now.

They roads are gone, But you can still basically see the clear cut through the trees where the road once was on the satellite views. But another 10-15 years and the new growth will grow enough trees that even the satelites won't define the old road beds.

There may be some like that hereabouts, but not many. About all you get is good-sized berms closing off logging tracks.

Anyway, roads that aren't there any more is only half the problem with Google &c. The other half is the perfectly good roads that do exist, and are driveable (though some you'd want 4WD) & rideable, and in fairly regular use, that just don't exist as far as they're concerned.

That reminds me of any of the Sunday editions of the Family Circus cartoon that track Billy wandering around the neighborhood.
