Building Footprint Ubid Folio - Buildings 200k Plus - View

It is an FC (polygon) of buildings located in Miami-Dade County that will use the UBID number for the application of the BE305 program in order to have a unique identifier for each building that participates in the program. UBID numbers were generated using a custom API, which calculated the UBID based on X, Y, XMin, YMin, XMax, and YMax values derived from the centroid of each building structure. The buildings were extracted from the existing Feature class, BuildingFootprint2D, which comprises polygon features for all buildings within and outside the Urban Development Boundary (UDB), covering approximately 938 square miles. The planimetric layer for Miami-Dade County was updated in 2024 by the Earth Sciences and Resources Institute of America (ESRI). This feature class includes features extracted from LiDAR data captured by ESRI in 2018. Definition of particular fields in the Buildings Footprint 2D feature class: Source = {"L", "P"} where L = LiDAR, P = MDC Planimetric Bld_type = {"S", "L"} where S = Small Buildings, L = Large Buildings本数据集为迈阿密-戴德县（Miami-Dade County）的多边形建筑要素类（Feature Class, FC），将采用UBID（Unique Building Identifier，建筑唯一标识符）编号为参与BE305项目的每一栋建筑分配唯一标识，以支撑该项目的应用。UBID编号通过自定义应用程序编程接口（Application Programming Interface, API）生成，该接口依据从每栋建筑结构质心提取的X、Y、XMin、YMin、XMax及YMax坐标值计算得到UBID。本次数据集的建筑要素从现有要素类BuildingFootprint2D（建筑轮廓2D要素类）中提取，该要素类包含城市开发边界（Urban Development Boundary, UDB）内外所有建筑的多边形要素，覆盖面积约938平方英里。迈阿密-戴德县的平面测绘图层于2024年由美国地球科学与资源研究所（ESRI）完成更新。该要素类包含从ESRI于2018年采集的激光雷达（Light Detection and Ranging, LiDAR）数据中提取的要素。建筑轮廓2D要素类的特定字段定义如下：Source字段取值范围为{"L", "P"}，其中L代表激光雷达（LiDAR）数据，P代表迈阿密-戴德县平面测绘数据（MDC Planimetric）；建筑类型（Bld_type）字段取值范围为{"S", "L"}，其中S代表小型建筑，L代表大型建筑。
