Buildings 3D

A polygon feature representing detailed building footprints providing a detailed footprint for each building in the City over 100 square feet in size. Footprints are segmented along breaks in rooftop elevations if multiple elevations exist. This data contains building base elevation, roof top elevation, and the height (the difference from roof top to base). Last updated 4/6/2026本数据集为多边形要素（polygon feature），包含该市范围内所有面积大于100平方英尺的建筑物的详细建筑基底轮廓（building footprint）。若建筑物存在多个屋顶高程，则沿屋顶高程分界处对建筑基底轮廓进行分割。本数据集包含建筑基底高程、屋顶高程以及建筑高度（即屋顶高程与基底高程的差值）。最后更新于2026年4月6日
