Historical, generalized built-up areas in U.S. core-based statistical areas 1900 - 2015
收藏资源简介：
An ESRI Shapfile containing spatially generalized built-up areas for each decade from 1900 to 2010, and for 2015, for each core-based statistical area (CBSA, i.e., metropolitan and micropolitan statistical area) in the conterminous United States. These areas are derived from historical settlement layers from the Historical settlement data compilation for the U.S. (HISDAC-US, Leyk & Uhl 2018). See Burghardt et al. (2022) for details on the data processing. <br> Additionally, there is a CSV file (HISDAC-US_patch_statistics.csv) containing the counts of built-up property records (BUPR), and -locations (BUPL), as well as total building indoor area (BUI) and built-up area (BUA) per CBSA, year, and patch, extraced from the HISDAC-US data (Uhl & Leyk 2018, Uhl et al. 2021). This CSV can be joined to the shapefile (column uid2) by concatenating the columns msaid_year_Id. <br> Spatial coverage: all CBSAs that are covered by the HISDAC-US historical settlement layers. This dataset includes around 2,700 U.S. counties. In the remaining counties, construction year coverage in the underlying ZTRAX data (Zillow Transaction and Assessment Dataset) is low. See Uhl et al. (2021) for details. All data created by Johannes H. Uhl, University of Colorado Boulder, USA. Code available at https://github.com/johannesuhl/USRoadNetworkEvolution.

本数据集为ESRI形状文件（ESRI Shapefile），涵盖美国本土所有核心统计区域（core-based statistical area，简称CBSA，即大都会与微型都会统计区）1900年至2010年每十年的空间概化建成区，以及2015年的对应数据。上述建成区源自美国历史定居数据汇编（HISDAC-US, Leyk & Uhl 2018）的历史定居图层，数据处理细节详见Burghardt等人（2022）的研究。 此外，本数据集还附带一份CSV文件（HISDAC-US_patch_statistics.csv），其中统计了按CBSA、年份与地块划分的建成房产记录数（BUPR）、建成地块位置数（BUPL）、总建筑室内面积（BUI）以及建成区面积（BUA），数据提取自HISDAC-US数据集（Uhl & Leyk 2018, Uhl et al. 2021）。可通过拼接msaid_year_Id列，将该CSV文件与形状文件的uid2字段进行关联。 空间覆盖范围：涵盖HISDAC-US历史定居图层所包含的全部CBSA，本数据集包含约2700个美国县份。其余县份的底层ZTRAX数据（Zillow交易与评估数据集，Zillow Transaction and Assessment Dataset）的建造年份覆盖度较低。相关细节详见Uhl等人（2021）的研究。所有数据由美国科罗拉多大学博尔德分校的Johannes H. Uhl创建，代码可在https://github.com/johannesuhl/USRoadNetworkEvolution获取。 参考文献： 1. Burghardt, K., Uhl, J., Lerman, K., & Leyk, S. (2022). 1900年以来美国城乡道路网络演化. 《计算机、环境与城市系统》 2. Leyk, S., & Uhl, J. H. (2018).
