NE2's Diary

Recent diary entries

Disney’s Pop Century Resort has an address of 1050 Century Drive. According to the Orange County Property Appraiser, Century Drive is the road from Victory Way to the parking lots, but no signs give the name. The only street signs, overhead internally-lit ones at the Victory Way traffic light, say “Disney’s Pop Century”. Someone following directions to turn at Century Drive may miss their turn.

My first inclination is to move the name to an unsigned_name field, but would this break anything such as address searching?

A more complicated case: the entrance to Coronado Springs has a name that is signed internally, but the signs at the entrance instead say “Coronado Springs”.

On implied turn restrictions and armchair mapping

Posted by NE2 on 10 February 2013 in English. Last updated on 11 February 2013.

I seem to have flipped from manic (“I can stop a bully with logic!”) to depressive (“what the hell was I thinking”) in the past few hours. Don’t bother me unless kicking a man when he’s down makes you feel bigger.

Today I made this movement in a Ford [s]Focus[/s] Escape (I’m usually a passenger and pay more attention to the road than details of the car) with no trouble with respect to staying off the striped gore. No signs prohibited this left-and-quick-right. (Note that the national MUTCD gives no prohibitory meaning to the single white line, and neither does Florida law.)

It remains to be seen if this is enough for Paul Johnson, who added a turn restriction prohibiting this movement based solely on aerials.

Potlatch 2 simple mode hides too much

Posted by NE2 on 8 November 2012 in English.

http://www.openstreetmap.org/browse/way/89902961/history Note that wambag changed the maxspeed (presumably correctly; the city recently took over maintenance from the state), but the source:maxspeed was not touched (and is thus incorrect now). I haven’t gotten a response, but it’s very likely that he was using PL2’s simple mode, which allows you to choose the maxspeed from a dropdown, but has no mention of source:maxspeed.

Possible solution: put a list of all tags at the bottom (possibly ignoring certain ones like TIGER), with some sort of hint showing the correlation between the simple tags up top and the ones at the bottom. This has the beneficial side effect of easing the learning curve.

Can someone explain this routing problem?

Posted by NE2 on 1 October 2012 in English.

http://map.project-osrm.org/1r9 The obvious route is to follow I-80 all the way. But instead it gets off and follows surface roads across Indiana.

Could it be avoiding barrier=toll_booth? The exit where it gets off (SR 66) is missing this. But why would it avoid toll roads without the user telling it to do so, and why wouldn’t it be using the toll=* tag on the ways?

The Three Stigmata of Potlatch Edits

Posted by NE2 on 5 September 2012 in English.

The following can be observed in many edits done in Potlatch 2, especially in simple mode.

  1. Nodes as one in two. Often a way will be drawn to intersect another not at an existing node but right next to it. It seems that PL2 has a problem with the minimum distance at which it assumes the user means to connect two nodes, and no obvious indication after-the-fact that something is wrong (since, unlike JOSM, nodes only appear when you mouse over a way). This causes not only redundant nodes but bad errors. For example, where a dual carriageway ends, there may be a tiny bit of one-way single carriageway, due to the node at the end of one direction being different from the one where the other direction and the single-carriageway continuation join. Hence the road is not routable in one direction.

  2. Too many tags. This may be a matter of personal taste, but what’s the point of adding oneway=no, bicycle=yes, foot=yes, cycleway=no, access=yes, motor_vehicle=yes to every street? (And sometimes people will think they have to fill in every value despite not knowing for sure what they are, leading to bicycle=no on major highways where cycling is actually legally allowed.) Related is the misuse of the designation tag, which, according to the wiki, is only for certain types of object in the UK, but has been incorrectly used for what belongs in name, ref, note, or other tags.

  3. Use of separators other than semicolons. The accepted way of tagging an overlap of two routes is with a semicolon; e.g. ref=I 80;I 90 for the long segment of toll road that carries Interstates 80 and 90 together. But PL2 displays this as red with a warning icon - “This tag contains more than one value - please check” - leading some mappers to “correct” the tag with a slash, dash, comma, or by deleting the second route.

Maybe in some cases, but with respect to splitting and joining ways, they're being extremely liberal and assuming that a new way ID is a new way wrt licensing. That is, unless they're not going to follow the precedent of the existing tools, in which case we're in rather deep shit.
