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

Data Transformation

Initial Data Prep Notes


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.
