Hi imports@ list,
The SF building height import team is working to add height data for
buildings in the City of San Francisco (wiki [0]). We'd like to revive
the discussion which was started back in May [1]. We now have a newer,
higher resolution height dataset from the city government released
un
First of all thanks for doing a more elaborate preparation than back in
May. The whole process is now much clearer.
To verify my understanding: the height values you assign are the median
height values of the city footprint data set when there is a matching
footprint within the area percentag
Hi Christoph,
For data accuracy:
Yes, our goal is to automate the tagging for flat-roofed and
unobstructed buildings. Sloped or uneven roofs and trees can be
identified in the JOSM hillshade tileset [0]. Mappers will then refer
to the raw LIDAR or street level imagery to determine the correct

Hi everyone,
We will start adding tags this week. A list of usernames that will be
performing the tasks is here:
https://github.com/osmlab/sf_building_height_import/issues/23
Tasks will be tracked at a new project on the main openstreetmap.us

May I ask how many of those currently importing building heights in San
Francsico live in the wider San Francisco area, or at

I was living in San Francisco but moved to the east coast this year.
I'm very familiar with the built environment and OSM there.

job, often involving

Frederik if you read the wiki, there are multiple examples proving +3m in
one case(out of 283m so very low in overall %), but a couple cm in
others(for big buildings). There is even an example to prove small
buildings are accurate as well.
It's cases like this that make me think some peop

And what I am saying is there will always be an error factor in
measurements/drawings, what your acceptable ranges are depends on the
community to define what is an acceptable error range vs what is not
acceptable.
Take for instance a gps point for defining a town's name, will 5cm affect
it much? P
I am sorry for not having the time to follow up on this in more depth.
The remarks in my reply from Nov 17 mostly still stand. I am not deep
enough into the matter to reliably asses if the concerns raised there
are warranted but i also have not seen any replies convincing me they
are not. I

Thanks everyone for your input - moving forward, we've continued to
recruit local mappers to ensure the long term success of the project.
These include some of the top contributors[1] of buildings in the
area, outside of the MapBox data team. FInd an updated list on the
Wiki here:
