Building Footprint Ubid Folio - Buildings 100k to 200k - 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本数据集为位于迈阿密-戴德县（Miami-Dade County）的多边形建筑要素类（Feature Class，FC），将采用UBID编号应用于BE305项目，为参与该项目的每一栋建筑分配唯一标识符。 UBID编号通过自定义应用程序编程接口（Application Programming Interface，API）生成，该接口根据每栋建筑结构质心导出的X、Y、XMin、YMin及XMax坐标值计算得到对应UBID。 建筑数据从现有2D建筑足迹要素类（BuildingFootprint2D）中提取，该要素类涵盖城市开发边界（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。 该要素类的地理空间数据源自ESRI于2018年采集的激光雷达（Light Detection and Ranging，LiDAR）数据。 针对2D建筑足迹要素类中的特定字段，其定义如下： - 字段Source：取值范围为{"L", "P"}，其中L代表激光雷达（LiDAR），P代表迈阿密-戴德县平面测绘建筑（MDC Planimetric） - 字段Bld_type：取值范围为{"S", "L"}，其中S代表小型建筑，L代表大型建筑
