Bedford County Building Footprints - Open Data

The Building layer is a spatial representation of all addressable structures within Bedford County, VA, as well as many non-addressable structures. These non-addressable structures include barns, boat docks, out-buildings, storage buildings, etc. The source of this data is the combination of many intermittent updates conducted through the Virginia Base Mapping Program (VBMP). The most recent update came from Orthophotography collected from VBMP's 2022 flight year. The original dataset was based on 1992 B/W orthophotography at 200" and 400" scales. In 2009, Bedford County contracted with Sanborn Map Company, Inc. to develop planimetric data based on the 2007 photography. The dataset was once again updated in 2018 and 2022 through the VBMP. GIS Staff is in the continual process of attributing building features with the name of the structure (e.g., church name, business name, etc.). This attribute information is valuable as a Landmark feature for Dispatchers in the PSAP, to show common, well-known structures and places within the County.建筑图层（Building layer）为弗吉尼亚州贝德福德县内所有可寻址建筑，以及大量不可寻址建筑提供空间表达。此类不可寻址建筑包含谷仓、船坞、附属小屋、储物建筑等。本数据集的数据源为弗吉尼亚基础测绘项目（Virginia Base Mapping Program, VBMP）开展的多轮间歇性更新成果的整合。本次更新的最新版本源自VBMP 2022飞行年度采集的正射影像（Orthophotography）。原始数据集基于1992年拍摄的200英寸与400英寸比例尺黑白正射影像构建。2009年，贝德福德县与桑伯恩地图公司（Sanborn Map Company, Inc.）签约，基于2007年的影像制作平面要素数据。本数据集又分别于2018年与2022年通过VBMP完成更新。地理信息系统（Geographic Information System, GIS）工作人员目前仍在持续为建筑要素添加建筑名称属性字段，例如教堂名称、商业场所名称等。此类属性信息可作为地标要素，供公共安全应答点（Public Safety Answering Point, PSAP）的调度人员使用，用于展示县域内常见且广为人知的建筑与场所。
