Retaining Walls 2017

Fugro was contracted to update the County's geodatabase, including planimetry, topography, orthophotography. Although the County covers approximately 245 square miles, the updates included approximately 301 square miles. All products extend one-half mile beyond the county boundary. Mapping was done at a scale of 1:1200, or 1" = 100'.Fugro受委托更新该县的地理数据库（geodatabase），更新内容涵盖平面测量（planimetry）、地形测量（topography）与正射影像（orthophotography）相关成果。尽管该县辖区总面积约为245平方英里，但本次更新覆盖范围约达301平方英里。所有测绘成果均超出县界向外延伸0.5英里。本次制图采用的比例尺为1:1200，即1英寸对应100英尺。
