[Talk-GB] LEZ get this completed?
Hi, I wonder if someone could help me complete this LEZ thing in London? I’ve only been able to add the boundaries from what I actually saw, but progress is incredibly slow. If an import is necessary, it has to be ODbL-okayed. ___ Talk-GB mailing list Talk-GB@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk-gb

Hi Antje, So you're talking about this? http://wiki.openstreetmap.org/wiki/LEZ#UK Looking at the relation we've got so far, I don't really see how we discover the border. I imagine in practice we'll see "You are now entering the LEZ" signs, so how do you manage to turn those into the (dis)continuous boundary lines that we've got so far?

Re: [Talk-GB] LEZ get this completed?
I live in London, so I could figure out a small part of the boundary based on the fact that it doesn’t go outside London for obvious reasons, and on the basis of a number of past surveys and personal memory (which I call leftovers). Do you think you want to change this relation to be node-based? I’m only going by what the Germans do for their LEZs. ___ Talk-GB mailing list Talk-GB@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk-gb

In reality there is no boundary, there are a series of entry/exit nodes on each road that can be joined, but any line will always be arbitrary.

Re: [Talk-GB] LEZ get this completed?
In my case, I have to consider the following: - How the boundary will avoid approved turn-backs like the London Gateway services on the M1. - How the boundary will avoid land that’s technically in the boundary but accessed by driveways that only enter from and exit into non- LEZ roads. You are right that an LEZ boundary is arbitrary and this is why the TfL version is clearly wrong. OSM can try its best to be as respectful as possible but it’s a learning process. ___ Talk-GB mailing list Talk-GB@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk-gb

There are very detailed maps of the boundary on the TFL website, but of course they are Ordnance-Survey-based, so cannot be used. http://www.tfl.gov.uk/maps/low-emission-zone -- Steve --- This email is free from viruses and malware because avast!

Nah, I already ignore those: they include land that’s technically in the boundary but accessed by driveways that only enter from and exit into non- LEZ roads. ___ Talk-GB mailing list Talk-GB@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk-gb
