Greetings, The argument that we map street center lines and add width= or est_width= tags to give them an area is persuasive. Probably because that's what I already believed. ;-) We can also estimate width by using the highway= or lanes= tags.
Mapping a car park to its edge (sidewalk, curb and gutter, etc.) also gives us something with an area. I suppose ways could even be drawn to show the entries to the car park. So... applications that use the data (renderers, etc.) should be able to deal with the case where the street center line is close to, but not coincident with, the bounds of an area such as a car park. The applications should also deal with the case where (part of) the bounds of an area is also a highway or waterway. Consider the case where a political boundary is defined by the center of a river. A single zero-width way serves as both the river center line and the political boundary. We have a similar case where a highway is carefully designed to follow a political boundary. It looks like we're back to "map what's on the ground" and our data consumers will use or ignore it as appropriate. -- --------------------------------------------------------------------- Joseph Scanlan http://www.qsl.net/n7xsd +1-702-455-3679 http://n7xsd.dyndns.org [EMAIL PROTECTED] (work) (not work) [EMAIL PROTECTED] --------------------------------------------------------------------- So he went inside there to take on what he found.
