Bridgedeck — NLCD Land Cover at Bridge Locations (2021)

Part of the bridgedeck dataset collection for US bridge deck deterioration research.

⚠️ Pipeline dependency — This dataset contains pre-queried NLCD land cover classes for all US bridge locations. It is shared to avoid re-running ~~906k WMS queries (~~2 hours). See sweetapricity/bridgedeck-nbi for the main bridge dataset.

Overview

NLCD 2021 land cover class queried at each unique US bridge location via the MRLC GeoServer WMS. Land cover is a proxy for urbanization, impervious surface coverage, and drainage characteristics — relevant to bridge deck deterioration through runoff patterns and pollutant exposure.
