I’m trying to figure out a workflow to fix these situations while preserving edit history. I am using JOSM.
In the example we have a single large building that houses 3 businesses. Only 2 of the businesses are on the map. In between Petco and OfficeMax is a liquor store that takes up about 25% of the area. It is not on the map.
What I want to do:
Take the combined outer ways of Petco and Office Max and turn them into a single way to represent the physical building.
Detach the shared nodes of the 2 businesses and resize them so I can put the liquor store between them
Do all this without screwing up the edit history or manually re-tracing the building
For step 1 (creating a single building):
It looks like if I go to Tools → “Combine way” or “Join Overlapping Ways” I get a box asking what tags to keep. In my mind, this suggests that if I follow through with this operation, it will join the 2 objects and we’ll have inaccurate data. What I basically want is a brand-new object and only put the building tag on it, without disturbing the existing tags on the businesses.
Step 2 (adjusting existing borders and inserting a new business):
I made a GPX track in which I walked along the front of the building where the liquor store is, so I have a pretty good idea where to place the nodes that delineate the new borders.
I suppose once I have my building drawn, I can unglue the 2 ways, use the extrude tool, then just draw 2 lines to put the liquor store in between the Office Max and the Petco. But I don’t want to disrupt the way that makes up the physical building.
I guess the source of my confusion is that by creating a building, I will have multiple ways all stacked on top of each other and I want to perform different operations on each one.
If what I am proposing is not the favored method to map multiple businesses in one building, let me know. I am still novice.
I ask as the two businesses that are mapped have two different street numbers, 350 & 370. What is the address of the liquor store?
(It’s for issues like this that I was always advocate for only having the building details & address on the building outline, together with a separate node for the business/es inside)
It is definitely all one building. In the USA it’s common to have separate addresses for different businesses in the same physical building. And it’s also common to have one address for a building, and the separate tenants (who share the same house number) get an additional number like “123 Main Street; Suite 210” or “123 Main Street; Unit 6” or sometimes simply “123 Main Street #9”
It seems to me that mapping a building and then putting individual nodes for businesses is acceptable practice, but I also often see it mapped like in my example where the one physical building has sub-areas delineating the separate businesses, so it’s up to the mappers’ discretion (I guess?).
In that case, I personally would draw it as only one building, tagged as 350-370, with 3 nodes inside it for the 3 businesses. If you wish, you can also include teh street addresses 350, 360 (I assume?) & 370 on them as well.
