Overview

Please do not attempt to import any features without first consulting the main contacts below.

The goal of this import is to add building and associated address data from publicly available datasets in Stillwater, OK.

The Github repository for all code is here: https://github.com/mikeshenson/Stillwater_OK_OSM_import as well as issues and project tasks.

Data that will be validated and imported on a neighborhood by neighborhood bases.

Source data

Summary

Data is provided by Stillwater. The datasets:

  1. Building Polygons:
  2. Address points:

The Building Polygons dataset will be referred to as "bldgs". The Address Points dataset will be referred to as "addrs".

License

These datasets are in the Public Domain

Process

The general process for importing data is described below.

Data processing

  1. Import building and address data into JOSM
  2. Import existing OSM buildings (building=*) into JOSM
  3. Any new building Polygons which intersect existing buildings will, for now, be ignored
  4. Tags will be created for each building as below


Address Tag Mappings

Remove all tags except "STNAME" and STTYPE to help assign correct addr:street tag.

tag source
addr:housenumber STNO
addr:street (expanded)STDIR + STNAME + (expanded)STTYPE (or use addr:full to correctly tag addr:street)
addr:unit STAPT
addr:postcode NEAR_FID
addr:city Stillwater
addr:state OK
addr:country US
addr:full STFULLNAME

Building Tag Mappings

Remove all tags.

tag source
building yes (follow table below)


source value final value
Residential Single Family house
Garage garage
RES, Res residential
Duplex, Apartment Complex, Multiplex, Residential Condominiums apartments
Dormitories dormitory
Everything else (the vast majority) yes

The bldgs dataset contains a column representing the use of the building "USAGE". The corresponding building= tag will be set as follows (based on http://wiki.openstreetmap.org/wiki/Key:building):

Addresses

Addresses points shall be merged with a building polygon when only one address point is inside or clearly attached to a building polygon. If there are multiple address points inside a building polygon, address points will remain as points.

Import Plan

All phases will be preformed on only one mile section at a time before moving onto the next mile section.

Phase 0: Accounts

  1. User "Stillwater_OK_GIS_Import" is owned by user mhenson
  2. Contributors/importers will create separate accounts followed by their normal usernames + "_Stillwater_OK_GIS_Import" for import purposes.

Phase 1: The easy stuff

  1. This phase will only deal with buildings that do not overlap with other features in OSM and have one (or no) address, or simple one building on one Accessors id with multiple addresses
  2. Contributors will download a section of buildings, and a section of address nodes and validate it in JOSM, verify them with local knowledge & against the most recent imagery available; likely NAIP imagery with Bing as a fall back.
  3. In JOSM assign correct address tags to the address points.
  4. In JOSM merge building polygons and address points if they clearly should be merged.
  5. At this time also verify that the street address matches the street name.
  6. Run the JOSM validation.
  7. After validation, the change set for that section will be uploaded by the contributor with a commit message that indicates it is part of this project.
  8. Uploads shall be small in size max 300 polygons at a time.

Phase 2: Reconciliation with existing buildings/addresses

This phase will involve conflating data to be added to buildings that already exist in OSM and dealing with any complex addressing issues.

Change Sets

Change Sets shall include text "https://wiki.openstreetmap.org/wiki/Stillwater,_OK_GIS_import"

Maintenance Plan

Contributors to this project are (and should be) Stillwater-area community members with an interest in keeping the data up to date.
