CORRECTION: Just one request though: when a sidewalk reaches the end, connect *it* back to the road

Hi there. Welcome to the OSM project! It looks like you have been mapping sidewalks. These look good so far. Just one request though: when a sidewalk reaches the end, connected back to the road (unless it truly ends with no connection). This will help with pedestrian/detour routing. You can use the "crosswalk" preset for mapping the connection. Thanks!

A few issues with this changeset that will prevent it from being accepted. 1) Don't match the edge of a landuse with a road (Wellington Valley)--it is OK to cross a road but not to touch it. Landuse polygons rarely share a boundary with a line or point. 2) super general changeset comments are discouraged. Try to write a sentence about what the purpose of the edit was at least and try to vary it from one edit to the next.

Awesome, there's a link to join on the Maryland wiki osm.wiki/Maryland

That sounds about right about the town/village issue, especially considering the shops along York Road in lutherville go back decades. So both L/T as town then?
I think that the USPS areas are more identifiable. The only issue is that some people do think of Mays Chapel as a place. I know folks that would definitely say that they live in MC, especially around that Grauls on Padonia. Lutherville or Timonium might be too generic for them. Happy to discuss more. If anything, the point for MC should probably be up closer to what I think of as MC, the area bounded by Timonium, 83, Jennifer and then Mays Chapel Elementary.

Indeed, you'll find some oddities in this data, as it is based on the legal land transfers, which sometimes are combined and thus the "plat" is not the boundary that you'd consider on the ground. It ends up being important for official purposes. These subdivisions are good for reference, though sometimes the local mapper knows more than the data tells.

Alright, it is split up. Generally, in OSM we use points to map stores if there is more than one use (store/office/apt.) per building. When there is just one store/office/etc. in a building, we'd just apply the relevant category to the building. If you're interested in mapping the shops there, add those places restaurants, shops, etc. as points.

Perfect! I'll chop up the building and then you can apply any shops or the like. The relation editing is best accomplished via the advanced JOSM editor.

Hey, coincidentally, Baltimore County GIS has published data just today that you can use for mapping subdivisions. This map shows "Conveyences" which are groups of plats (aka subdivision plats) in County GIS jargon. The boundaries are official, however. In the past, I received permission to use County data for OSM (such as all of the buildings on the map). I believe this still applies, so feel free to reference this map for mapping subdivisions. http://data-bc-gis.opendata.arcgis.com/datasets/217c84d9ed914b01afff255f8abf950f_2?geometry=-76.682%2C39.422%2C-76.602%2C39.433

Looks good! I was just over here the other day and scouted a tiny path between that northern edge of the parking lot and The Meadows Neighborhood. Those types of things are useful to add--unofficial type paths, as it helps ped routing software find routes.

Would you say that the way the pavilions are split in this photo is representative of how you'd split them? https://goo.gl/photos/wEbpoGr8T5jCX5GU9

This situation is pretty unique to Baltimore County and that the mapping community, unfortunately, does not have a great answer for. Baltimore County is somewhat unique in the US in that there are no incorporated towns in it. Thus, things like Towson and Timonium don't have any official existence at the local government level. However, two federal entities define these places differently: the USPS and the Census. The USPS ZIP Codes associated towns (the list you cited) are how people identify with a place here. However, the Census, strangely, has decided to break up the 21093 area into these three zones, and the boundaries are not the same. A few years ago I attempted to streamline the hodge-podge list of towns and villages in Baltimore County objectively, by population. However, as you point out, this numbers-only definition doesn't exactly mirror the situation on the ground.
I think that we should go ahead and make MC a village, and then Timonium a town. I always thought of "Lutherville" as the area south of Ridgely that is mostly residential, thus maybe that should be a village. Timonium, meanwhile, does have an urban core of sorts around the fairgrounds. What do you think?

TJ, that is a great point, and I'm glad you made it. I am happy to help out. Place classification is a contentious thing in the community so I do apologize if it seems harsh. Often times we'll see edits where someone will reclassify every town or do some mechanical edits. In the past, we had Lutherville-Timonium combined as one place. The census chopped them up and now classifies Mays Chapel separately. However, as you pointed out, there is no real "urban centre" in Mays Chapel. At best, you might call it the shops along Padonia. Given this point, I think that perhaps the population alone shouldn't be the deciding factor. Do you want to join our Slack channel to discuss? I think you'd find lots of helpful information there, and good people to chat with about the map. Cheers - Elliott

Good work here! If you know of some more neighborhood boundaries to add, the community welcomes these kinds of additions.

Hey there, solid work on these edits. I added the connecting sidewalks to show the standard for mapping these kinds of features. Make sure that your footpaths connect to another highway-way. This allows routing across the network. Thanks!

Hello again. Have you visited Greenspring Valley lately? I was just there and removed the raquet club as a building and change it to construction because that building is being demolished. The parking lot is also closed. While the community welcomes contributions, we'd ask that you don't change the status of a building or landuse without checking it out in reality first. I'll go ahead and roll this one back. Thanks!

Hello again and thank you for your contributions. These particular changes are not appropriate, however. As you may know, Lutherville, Timonium, and Mays Chapel are not incorporated towns, nor are any in Baltimore County. The OSM community has discussed this at great length and reached the (somewhat arbitrary) conclusion to let the population of a CDP be the guide to the difference between hamlet, village, and town. In Baltimore County, any CDP with a population of less than 10K is a village. Anything over is a town. If you're interested in discussing more, feel free to discuss with the Maryland community on OSM. Look us up on the OSM wiki. Thanks!

Hello there, I can address this. The names you see on various maps are governed by the style guide for those maps. The data itself is correct though. What map do you see this issue on?

Hello and welcome to OSM! Thanks for contributing. I see that in this changeset you removed the Heatherfield neighborhood. If you have knowledge that this is not a commonly used name, feel free to remove the name, but leave the polygon. I went ahead and added back the polygon without that name. Thanks!

These tags with the builder name are pretty cool. Bravo
