City of York County Buildings/Address Import
This project aims to import York County, Va buildings from a city-sourced GIS file.
Goals
Import York County's building footprints dataset to help York County mappers create a more effective map. Get highly accurate, city-wide address data.
Import Data
Background
Data source site: York County, Virginia GIS department has provided building footprints, address points, and points of interest for importing into OpenStreetMap after a request via email. The data was graciously provided as is, license free, and at no cost by the GIS department with the note:
"..York County’s FOIA policy still allows our department to charge for GIS data, however we have decided to provide some GIS data to not for profit organizations.."
ODbL Compliance verified: yes
OSM Data Files
Initial pass at OSM files here.
Import Type
This import will be done in sections based on zip codes with JOSM under the username: jonahadkins_yorkcounty_import
Data Preparation
See GitHub Repo for additional details on this import -> York County, Va Import Repo
Changeset Tags
I will set source=York County GIS
Attribute Tags
County Buildings contain building types that will be mapped to building and amenity tags. Addresses will be mapped to through buildings. Business names are contained in the place names file and will be mapped into building name.
Data Transformation
Conflation
Since the OSM data is being hand-imported in manageable chunks, conflation with existing data will be handled manually in JOSM. I will prefer existing OSM data and tags over the imported data and will try to apply addressing tags from the York County data as correctly as possible.
