If yahoo or bing imagery isn't available, and if it was an accidental deletion, I'd suggest perhaps tracing the road from the OpenCycleMap tiles, as they render less frequently and the tiles are available now.

Also, maybe there seem to be some gps traces visible in potlatch 2, so tracing the gps trace may give a better map.

The road just to the south was redrawn a couple days ago, so maybe that person is on a mission to redraw a huge area. So it may be a work in progress. (thinking positively here) I'd suggest sending him a message asking if he was the one who deleted it and/or if he's redrawing it.

Hopefully it wasn't the xybot going out of control.

it might be related to a 'yahoo import'. The road just south of the deleted area seems to be part of a 'yahoo import' which is a huge edit.

I like the Garmin Oregon. I use it for cycling, and I've made an OpenCycleMap overlay for my city.

Yep. It's like a journal... I used mine to make a note of what is on my todo list. All the discussions show up under the User Diaries tab.

All it needs is to connect to TV-3025 (assuming it connects, I don't have local knowledge of the area)
You can edit the map, click on the top right node, and continue the path, and click on a point on tv-3025.

Welcome to OpenStreetMap.

speaking of truckers, should we have limits for 'max height' for roads, and 'max weight' for bridges? Or is a 'heavy vehicle' tag more widely used?

Well, for discussion sake, a person who clicked the 'I Consider my work to be Public Domain' checkbox (me), deleted one of your paths, and put in their own Bing traced playground instead. osm.org/browse/changeset/7940134 This is the kind of edits we will be seeing if we do a 'purge' of map data - it's a silly edit, and it's point is to prove how silly a 'delete and recreate' edit is.. I think this type of edit does not contribute to OSM... besides, the original contributors granted the OSMF the right to use their work. I don't think there will be a huge purge which creates holes in the future map. I don't think we have to go and proactively delete things.

no, your exact words were "So I am deleting the roads (or whatever) and recreate it. "

The old edits were "cc-by". People shared their stuff with the only restriction being that they were attributed.

An individual edit isn't "The database"

There's nothing "wrong" with the old edits. In fact, the old edits were more Open than the new edits.

Old edit: CC-BY Just attribute the original editor.
New edits: CC-BY-SA Attribute the editor, and 'share alike'.

While your'e at it, are you doing to purge the stuff that was public domain? Ie, the TIGER data in the states and the Canvec and Toporama data from Canada?

Deleting CC-BY data is the equivalent of burning free books because they don't have a copyright symbol on them. It's destructive, and it takes away from the public knowledge.

Basically, you're copying someones work and not crediting them as per the CC-BY license they had on it.
You're taking someones drawing of a road or a path and tracing it out and putting a more restrictive CC-BY-SA on it.

What you're doing is laundering other people's work to change the license on it. We don't do it with copyright work, and we don't do it to copyleft work.

Why?

Yeah. I would have preferred a BSD license. Total freedom.

cool, I shall start using railway=subway_entrance from now on.

suggestion for an addendum for the 'How you can help' section.
People can even print out a section the map that needs updating, sketch up some changes, scan it or take a picture, and upload it to WalkingPapers.org .

I really don't see why people spam the OSM diaries. At best, they'd only get 4 or 5 clicks from people curious to see what the site is. It's like they spend all that effort to get a penny. They'd be more profitable looking for coins in couch cushions or recycling beverage containers.

I've used the Mobile Atlas Creator. I noticed that even Google has issues with people downloading mass amounts of tiles as well. I've triggered a limit with google tiles when creating an offline map for my GPS, and couldn't use Google Maps for a couple of days.

Some ideas:
Put a soft limit into your app: ie, have it keep downloads to 20 megs. It will make users rethink downloading a whole country's tiles at once.

Build a renderer into the app. If Android's Mapdroyd can render tiles on my phone, then your app can render it's own OSM tiles. A bonus feature is that you could have custom render styles for Biking, Cars, Hiking, Taking the Bus, etc.

What would be a benefit for the cycling users if they were to update openstreetmap, and then be able to generate a new cycling map for their GPS (Yes, we all do it to have Custom Maps on our Oregon GPS's) without having to wait a week or so for the heavily loaded OpenCycleMap to render the new bike path.

I found that with mapdroyd, if you're in a coastal city, you really need the 'detailed coastline' map package so the city renders properly.

Sorry, wrong link, here's Portland.

For routing, I'd suggest fixing the 'unconnected' intersections reported by Keepright. http://keepright.ipax.at/report_map.php?zoom=12&lat=49.086&lon=-122.73546&layers=B00T&ch=0%2C50%2C191&show_ign=1&show_tmpign=1

It might look like a whole lot of work, but if you do one neighbourhood at a time, you'll progress thru the map fixing unconnected ways.

Best of luck on your new routing tool.

The above 'technology' link has no relevence to this thread. (I think it's spam)
