The 1990-2020 wildland-urban interface of the conterminous United States - geospatial data: 4th edition

The Wildland-Urban Interface (WUI) is the area where houses meet or intermingle with undeveloped wildland vegetation. This makes the WUI a focal area for human-environment conflicts such as wildland fires, habitat fragmentation, invasive species, and biodiversity decline. Using geographic information systems (GIS), we integrated U.S. Census and USGS National Land Cover Data, to map the Federal Register definition of WUI (Federal Register 66:751, 2001) for the conterminous United States from 1990-2020. These data are useful within a GIS for mapping and analysis at national, state, and local levels. Data are available as a geodatabase and include information such as housing densities for 1990, 2000, 2010, and 2020; wildland vegetation percentages for 1992, 2001, 2011, and 2019; as well as WUI classes in 1990, 2000, 2010, and 2020.To provide a spatially detailed national assessment of the wildland-urban interface (WUI) and WUI change between 1990 and 2020 across the coterminous U.S. to support wildland fire research, policy and management, and inquiries into the effects of housing growth on the environment.This data publication, published on 08/09/2023 is a fourth edition. The first edition (https://doi.org/10.2737/RDS-2015-0012) contained data representing the 2010 WUI of the conterminous United States. The second edition (https://doi.org/10.2737/RDS-2015-0012-2) contained data that represented the 1990-2010 WUI. The third edition (https://doi.org/10.2737/RDS-2015-0012-3) contains data that represent the 1990-2020 WUI.

This fourth edition uses an improved PLA housing density dataset to classify WUI from 1990-2020. This involved updating the public land adjustment (PLA) process (step 1) by correcting topological errors and removing erroneous sliver polygons generated during the PLA process.

野地与城市界面（WUI）是指房屋与未开发野地植被相遇或交织的地区。这一区域因野地火灾、栖息地破碎化、入侵物种和生物多样性下降等人类与自然环境冲突而成为焦点。利用地理信息系统（GIS），我们整合了美国人口普查局和USGS国家土地覆盖数据，绘制了联邦登记中对WUI的定义（联邦登记66：751，2001年）在1990年至2020年期间美国本土的地图。这些数据在GIS中可用于国家级、州级和地方级的数据映射和分析。数据以地理数据库的形式提供，包括1990年、2000年、2010年和2020年的住房密度信息；1992年、2001年、2011年和2019年的野地植被百分比；以及1990年、2000年、2010年和2020年的WUI类别。这些数据旨在提供1990年至2020年美国本土野地与城市界面（WUI）的详细空间评估，以及WUI的变化情况，以支持野地火灾研究、政策制定和管理，以及对住房增长对环境影响的探究。本数据出版物于2023年8月9日发布，为第四版。第一版（https://doi.org/10.2737/RDS-2015-0012）包含代表美国本土2010年WUI的数据。第二版（https://doi.org/10.2737/RDS-2015-0012-2）包含代表1990-2010年WUI的数据。第三版（https://doi.org/10.2737/RDS-2015-0012-3）包含代表1990-2020年WUI的数据。本第四版采用改进的PLA住房密度数据集对1990-2020年的WUI进行分类。这包括通过更新公共土地调整（PLA）流程（步骤1）来纠正拓扑错误和移除PLA流程中产生的错误细长多边形。有关WUI的信息还可在此处查阅：http://silvis.forest.wisc.edu/data/wui-change 以及 https://www.fs.usda.gov/research/nrs/projects/wuigrowth。
