The roads that I am talking about are forest service roads. They just are built and maintained by the companies that work in the area, rather than the government. If these companies want access back into the bush to drag trees out, it is up to them to build and maintain the access roads. I'm trying to find an equivalent road using Google Street view, but it's a little challenging... Here's a link to a road through the bush near Salem, Or. http://tinyurl.com/yjh7xgw This is a paved 2 lane road. If you were to double the width of this road, straighten it out, and change the surface to gravel, you'd have something similar to what I am talking about. Here's a link to a smaller road that takes you from the government road grid up to the top of Whitecourt Mountain where there's a forestry lookout tower, and also a bunch of radio towers. http://tinyurl.com/y9notsa Here's a link to a paved road in the bush in Oregon. http://tinyurl.com/yhpd4xw Both are at the same zoom level. The smaller road in Alberta is larger and easier to see from the air than the one in Oregon. Here's the Oregon area in OSM... http://www.openstreetmap.org/?lat=45.156&lon=-123.5106&zoom=15 SW Gilbert Creek Road is tagged as a track... a paved striped roadway! Zoom in and out using Google maps... you'll see some of the main roadways, ones that you could travel long distances between far flung towns upon still show when zoomed out, making the map useful for planning a route. If all the roads are tagged as tiny little trails in the bush, the road map information becomes useless. > I'm not quite certain what you're going for... I'm going for creating a map database that would be useful for people travelling in the area. I can turn off of a government highway, and drive for 2 hours on private roads, popping out onto another government highway 100 miles away. I can do this using maps that depict these private roads in such a way that I can easily pick out roads that go between the places I want to go. I can also look at a tighter zoom level map to see the minor roads that will take me to the intermediate destination, such as a radio tower on a hilltop somewhere between those two government highways. Try planning a route where you're either looking at a blank page, or having to look at a super detailed map of perhaps 10 square miles. Try planning your route between Salem and Corvalis but you'll have to do it at zoom level 14 on OSM, and pretend that all the roads are residential, where they are all white, including the primary highways, and motorways. How long would it take you to figure out the route to take between the two cities? Would you be able to pick the fastest and best quality roads? I am talking about setting road tags to help people understand the road network. The tags may not exactly match the descriptors on the OSM wiki, but I don't like in the UK...
