Existing Structure Area

This layer contains building polygons for all addressable structures in the City (ADDRESSTBL "Y") as well as many non-addressable structures. The buildings can be linked to the "MASTER ADDRESS TABLE" table (via BIN) to yield additional information including building addresses.本图层涵盖本市所有字段ADDRESSTBL="Y"对应的可寻址建筑的建筑面状要素（building polygons），以及大量不可寻址建筑的面状要素。此类建筑可通过BIN与主地址表（MASTER ADDRESS TABLE）建立关联，进而获取包含建筑地址在内的额外信息。
