Research Data Publication File Index

File Folder Description
_metadata_RDS-2020-0060.html   Metadata file in HTML format containing a description of the content, quality, and other characteristics of the data.
_metadata_RDS-2020-0060.xml   Metadata file in Extensible Markup Language (XML) format containing a description of the content, quality, and other characteristics of the data.
BuildingCover_*STATE*.tif \Data\*STATE* Georeferenced TIFF files, provided for each U.S. state and the District of Columbia, containing continuous integer values of percent cover of buildings with a 30-meter (m) pixel size. Values are between 0 and 100.

Note applicable for all .TIF files in this package:
Associated .OVR files are included and contain pyramids that allow the raster datasets to draw more quickly is GIS software. Associated .XML files contain dataset-specific FGDC-CSDGM metadata containing a description of the content, quality, and other characteristics of the data. Other associated files include .TFW, .AUX.XML, .VAT.CPG, and .VAT.DBF, and contain spatial reference, statistics, and attribute information.
BuildingExposure_*STATE*.tif \Data\*STATE* Georeferenced TIFF files, provided for each U.S. state and the District of Columbia, containing continuous floating point values of exposure type that depict the type of wildfire exposure a housing unit would experience with a 30-m pixel size. Values are between 0 and 1. Referred to in the Wildfire Risk to Communities web application as Exposure Type. A value of 1 is "direct" exposure. Values between 0 and 1 represent "indirect" exposure, with higher values representing closer proximity to directly exposed areas (i.e., areas of burnable wildland vegetation). A value of 0 represents "nonexposed" areas that have nonburnable land cover and are more than 1530 m (approx. 1 mile) from burnable wildland vegetation.
HUDen_*STATE*.tif \Data\*STATE* Georeferenced TIFF files, provided for each U.S. state and the District of Columbia, containing continuous integer values of 2018 housing unit density with a 30-m pixel size. Values are between 0 and 65,582. Units are housing units per square kilometer (sq km). Housing units are any structures that have residential population associated with them and include single-family and multi-family residential buildings as well as facilities such as prisons, dormitories, barracks, and nursing homes.
HUExposure_*STATE*.tif \Data\*STATE* Georeferenced TIFF files, provided for each U.S. state and the District of Columbia, containing continuous floating point values of housing unit exposure with a 30-m pixel size. Values are between 0 and 0.17245. Units are the expected number of housing units per pixel exposed to wildfire in a year. This is a long-term average and not intended to represent the actual number of housing units exposed in any specific year. Calculated as the product of wildfire likelihood and housing unit count.
HUImpact_*STATE*.tif \Data\*STATE* Georeferenced TIFF files, provided for each U.S. state and the District of Columbia, containing continuous integer values of housing unit impact with a 30-m pixel size. Values are between 0 and 2,000,000,000. It is a unitless index.
HURisk_*STATE*.tif \Data\*STATE* Georeferenced TIFF files, provided for each U.S. state and the District of Columbia, containing continuous integer values of housing unit risk with a 30-m pixel size. Values are between 0 and 12,591,000. It is a unitless index.
PopDen_*STATE*.tif \Data\*STATE* Georeferenced TIFF files, provided for each U.S. state and the District of Columbia, containing continuous integer values of 2018 population density with a 30-m pixel size. Values are between 0 and 159,332. Units are people per sq km.
BuildingCover_CONUS.tif \Data\CONUS Georeferenced TIFF files provided as mosaics for the conterminous U.S. (CONUS) containing continuous integer values of percent cover of buildings with a 30-m pixel size. Values are between 0 and 100.
HUDen_CONUS.tif \Data\CONUS Georeferenced TIFF files provided as mosaics for the conterminous U.S. (CONUS) containing continuous integer values of 2018 housing unit density with a 30-m pixel size. Values are between 0 and 65,582. Units are housing units per sq km. Housing units are any structures that have residential population associated with them and include single-family and multi-family residential buildings as well as facilities such as prisons, dormitories, barracks, and nursing homes.
HUImpact_CONUS.tif \Data\CONUS Georeferenced TIFF files provided as mosaics for the conterminous U.S. (CONUS) containing continuous integer values of housing unit impact with a 30-m pixel size. Values are between 0 and 2,000,000,000. It is a unitless index.
HURisk_CONUS.tif \Data\CONUS Georeferenced TIFF files provided as mosaics for the conterminous U.S. (CONUS) containing continuous integer values of housing unit risk with a 30-m pixel size. Values are between 0 and 12,591,000. It is a unitless index.
PopDen_CONUS.tif \Data\CONUS Georeferenced TIFF files provided as mosaics for the conterminous U.S. (CONUS) containing continuous integer values of 2018 population density with a 30-m pixel size. Values are between 0 and 159,332. Units are people per sq km.
