Building Footprint Ubid Folio - Buildings 20k to 30k - 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-戴德县的建筑多边形要素类（Feature Class，FC），将采用UBID编号为参与BE305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（API）生成，该接口基于每栋建筑结构质心提取的X、Y、XMin、YMin、XMax及YMax值计算得到。 所有建筑数据均从现有要素类BuildingFootprint2D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，覆盖范围约938平方英里。迈阿密-戴德县的平面制图图层于2024年由美国地球科学与资源研究所（Earth Sciences and Resources Institute of America，ESRI）完成更新，该要素类的数据源自ESRI于2018年采集的激光雷达（LiDAR）数据。 建筑足迹2D（Buildings Footprint 2D）要素类中特定字段的定义如下： 1. Source字段可选取值为{"L", "P"}，其中L代表激光雷达（LiDAR）采集数据，P代表迈阿密-戴德县平面测绘数据（MDC Planimetric）； 2. Bld_type字段可选取值为{"S", "L"}，其中S代表小型建筑（Small Buildings），L代表大型建筑（Large Buildings）
