Import/Catalogue/Fayetteville Building Footprints
About
I plan to import building footprints for Fayetteville, AR. Fayetteville largely lacks footprints, and I feel this would add a good point of reference and nice level of detail to the map.
Import Data
Background
These are the building footprints delivered with the 2016 aerial imagery to Washington County, AR and Fayetteville, AR.
Data source site: [1]
Type of license: Public Domain
ODbL Compliance verified: yes
Import Type
This will be a one-time import done in JOSM.
Data Preparation
Data Reduction & Simplification
The origin dataset contains building footprints for all of Washington County. At this time, I plan to only import those within the City of Fayetteville. Rural Washington County may come in a later phase.
Tagging Plans
The building footprints have been spatial joined with City of Fayetteville address points, available here: [2]
This allowed for the following address tags to be automatically assigned for most footprints:
In addition to the address tags, I have also been able to determine the building classification based on the address CLASS field.
Changeset Tags
There are no plans to use changeset tags at this time.
Data Transformation
The data has been converted to WGS84 from State Plane Arkansas North, and broken down by chunks mostly bounded by major roads for import. The chunks are the numbered areas in the graphic below:

An example changeset can be found here; chunk #1090 has already been completed!

Data Merge Workflow
Team Approach
I plan to do this solo.
Workflow
- The pre-processing work has already been done
- The footprints will be loaded in for a given chunk
- Reconciliation/conflation will then be done manually with any existing features in said chunk
- The process will continue until all 116 chunks are finished.
QA
I plan to check my work by referencing the 2016 imagery layer (more accurate and up-to-date than Bing). This imagery layer is available for public consumtion here:
