sample_boxes
Spatial Information: 14,400 records; each polygon and row = one sample box.
Format: file geodatabase polygon feature class Feature Dataset: boundaries Primary Key: SampleBox_ID Attributes:
Scale: unknown. Source: Custom dataset created for the project for use as the main unit of analysis in spatial/statistical analyses. Each sample box is ~ 0.5 square miles by 0.5 square miles. Sub-division of sample boxes, with 36 sample boxes per sample grid. |
sample_grids
Spatial Information: 400 records; each polygon and row = one sample grid.
Format: file geodatabase polygon feature class Feature Dataset: boundaries Primary Key: SampleGrid_ID Attributes:
Scale: unknown. Source: Custom dataset created for the project used to delineate sample areas in which we created land use data. Each sample grid is ~ 3 square miles by 3 square miles. Boundaries are based on the Public Land Survey System. |
counties
