Building Footprints

This map service represents building footprints for the City of Newport News, VA. This layer is based on a combination of photo derived building polygons digitized from 2016 Aerial photography and manually updated polygons based on site and building plans. Buildings are updated periodically as required.本地图服务提供弗吉尼亚州纽波特纽斯市的建筑基底轮廓（building footprints）数据。该图层的数据融合两类来源：一类为从2016年航空影像中数字化提取的影像派生建筑多边形，另一类为依据现场勘测与建筑图纸手动修正的多边形。建筑基底轮廓数据将根据实际需求定期更新。
