<html><body style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; ">I've come to this discussion late, because the tagging listserv is relatively new, and I haven't been monitoring it regularly. I don't have anything like a definitive suggestion to Randy's original problem or the variants added to it in the subsequent discussion, but I'd like to add something else for consideration.<div><br></div><div>I'm tagging sidewalks on the University of South Florida in Tampa, and we have a number of situations where a sidewalk goes through a building. In effect, much of the ground level of the building is open to the elements, and the sidewalk goes under the second floor. Doors to offices and other rooms open onto the sidewalk. This seems to have been a style here in the 1970s. There are two variations of this. </div><div><br></div><div>In one, the sidewalk runs between two parts of the ground floor of the building (like a tunnel). Doors (and elevators and stairways) may front onto the sidewalk as it passes through. I have been tagging portion of these sidewalk that goes through these buildings as highway=footway, tunnel=yes, because from the perspective of the sidewalk, it is a tunnel. But I've not been entirely comfortable with it. This is, I think, the situation that Randy identified, but for sidewalks.</div><div><br></div><div>In the other, the sidewalk runs along the side of the ground floor of the building, with grass on one side, the building (often with doors opening onto the sidewalk) on the other, and the second floor of the building overhead. These have been problematic. They function as sidewalks but are not quite normal sidewalks, and they definitely are not tunnels</div><div><br></div><div>One of the reasons I'm doing this mapping is because we want to develop a walking-route finder for students using wheelchairs. As part of this, I've been considering proposing a tag shade=*, intended to apply to a sidewalk or street (mostly sidewalks, though), with the following values based on midday shading:</div><div><br></div><div>=trees, if the way is heavily shaded by trees (not intended for areas on a way shaded a single tree, but for a length of way with shade covering a substantial part of the length)</div><div>=pergola, if the way is covered by a pergola or similar trellis with plantings dense enough to provide shade</div><div>=roof if the way is covered by an awning or similar roof impervious to rain. Intended for a free-standing structure built for the purpose of covering the sidewalk</div><div>=building if the way hugs the north side of a building and is shaded by it (this would apply in latitudes farther north than here--in midsummer the sun is too high)</div><div>=portico if the way runs beneath a canopy, colonnade, or similar projection of the building that provides shade and shelter but, depending on the orientation of the way, might provide shade at noon and in the morning, but not in the afternoon (or vice versa). This is the value that I have been considering for the second case above (building on one side, grass on the other, second level overhead. Older parts of some European cities are full of these. Better-designed commercial developments also have extended awnings/canopies attached to the front of the buildings, shading the sidewalk that runs along the front of the shops.</div><div>=none would be the implied value if shade=* is not coded, although I would understand if a mapper coded it to make a point during a hot shadeless afternoon walk.</div><div>Maybe other values, but these are the ones I've encountered here, or thought about. shade=trees could apply to older streets as well as sidewalks, but I doubt the other values would apply to streets very often. Shade=trees would also apply to stretches of hiking paths (below treeline, obviously) and cycle paths, distinguishing them from stretches through meadow, rockfields, talus, etc. Useful for planning a hike.</div><div><br></div><div>Knowing about shade would allow the eventual routing application to trade off using a slightly longer shady route vs a shorter one without shade. Because of trees, we can't just tag shade in association with a building or architectural element</div><div><br></div><div>There are other situations, such as some of the early grand commercial arcades, that are structurally similar to the example that Anthony provided at <a href="http://images.loopnet.com/xnet/mainsite/attachments/viewImage.aspx?FileGuid=C138EA3D-33CE-4695-AA32-11C4C9C097EA&Extension=jpg&Width=631&Height=421">http://images.loopnet.com/xnet/mainsite/attachments/viewImage.aspx?FileGuid=C138EA3D-33CE-4695-AA32-11C4C9C097EA&Extension=jpg&Width=631&Height=421</a> (by the way, Anthony, I like your work in detailing the commercial complex that I'd merely traced the outline for). If there were a tag for "arcade" or something like that, I would use it, not for shade, but because it describes the overall situation, and shade would be implied. Because of its size, location and other functions, and the orientation of the doors, the multistory lobby of new student center on the campus now functions as a sidewalk. Students routinely cut through the building on their way from places to the north, to places to the south, or vice versa. So it is a bit like an old arcade as well, but I'm sure it was not intended to be a shortcut for students walking from one part of the campus to another.</div><div><br></div><div>I would welcome any suggestions you have on how to deal with the open-building situations, the student center, or shade. Yes, in a way, these are minor, even trivial situations, but they contribute to the quality of the local environment, and it would be good to be able to record that in OSM.</div><div><br></div><div>Ed</div><div><br></div><div><div style="margin-top: 0in; margin-right: 0in; margin-bottom: 0.0001pt; margin-left: 0in; font-size: 11pt; font-family: Calibri, sans-serif; "><b><span lang="NL-BE" style="color: green; ">Edward L.
