Historical building footprint area (BUFA) - gridded surfaces for the conterminous U.S. from 1900 to 2010
<|begin_of_text|><|start_header_id|>system<|end_header_id|> You are a research archivist expert in dataset metadata. Answer the question truthfully.  <|eot_id|><|start_header_id|>user<|end_header_id|> Here is the Description of a dataset. Description:'These files are part of the dataset 'Historical building footprint areas (BUFA) - gridded surfaces for the conterminous U.S. from 1900 to 2010', contained in the dataverse “HISDAC-US: Historical Settlement Data Compilation for the United States” (https://dataverse.harvard.edu/dataverse/hisdacus). Each GeoTIFF file contains a geospatial raster layer with pixel values representing the total building footprint area (i.e., the built-up surface in m²) within each 250 m x 250 m grid cell, at 10 years temporal resolution. The .readme file provides additional information on the underlying methodology.
