Methods

PLACES-FMV (CONUS) contains parcel-level estimates of the fair market value (FMV) of vacant and “mostly” vacant properties in the contiguous United States (see data products).

The estimation component develops these estimates from statistical models. Our models are trained on samples of private land transactions at various geographic scales using simple estimators (linear regressions, tree ensembles) and publicly available predictors.

The validation component examines the strength of correlations between the resulting FMV estimates and the observed cost of public land acquisitions and conservation easements in the contiguous United States.
