| Variable | Units | Description | Source | Layers |
|---|---|---|---|---|
| Distance to Roads | m | Euclidean distance from each grid cell to the nearest road feature across all road classes in the TIGER/Line dataset. | USCB TIGER | |
| Distance to Roads (Primary/Secondary) | m | Euclidean distance from each grid cell to the nearest primary or secondary road feature in the TIGER/Line dataset. | USCB TIGER | |
| Distance to Roads (Primary/Secondary/Local) | m | Euclidean distance from each grid cell to the nearest primary, secondary, or local road feature in the TIGER/Line dataset. | USCB TIGER | |
| All Roads 30 m Raster | — | Rasterized representation of all TIGER/Line road features at 30 m resolution. Cell values indicate the presence of any road class. | USCB TIGER | |
| Roads Primary/Secondary 30 m Raster | — | Rasterized representation of primary and secondary TIGER/Line road features at 30 m resolution. Cell values indicate the presence of a primary or secondary road. | USCB TIGER |
