This research adapts the GQ inclusive Cadastral Expert Dasymetric System to estimate small area human population distribution in 6 counties. Maps are produced at parcel level and masked using Microsoft Building Footprint data to define sub-parcel units, allowing group quarters to be geocoded to appropriate structures. Estimates are assessed against block level decennial census estimates at 10m resolution, and aggregated to the 1km U.S. National Grid (USNG). This presentation will follow up with the 2019 presentation, covering an overview of the estimation method, regional model variations, and their unification towards a statewide estimation model.
