Stormwater – Manholes

Stormwater manholes were field collected within the project area for the Storm Drain System (MS4) GIS Mapping Project for Boulder County Public Health. The data was collected with a Trimble Geo-XH 6000 with a horizontal post-processed accuracy of 2.5 cm (.98in). The data was post processed using the base stations located in and around Boulder County. The data dictionary used to collect the data was developed in collaboration with the Boulder County Public Health Project Manager. This data was collected between April and December 2017 by Anderson Consulting Engineers.本数据集的雨水检查井样本采自博尔德县公共卫生部雨水排放系统（MS4）地理信息系统（GIS）绘图项目的指定项目区域。数据采集使用天宝Geo-XH 6000设备，经事后处理后的水平定位精度可达2.5厘米（0.98英寸）。本次数据的事后处理工作依托博尔德县境内及周边的基准站完成。本次数据采集所使用的数据字典由项目团队与博尔德县公共卫生部项目负责人合作制定。该数据集由安德森咨询工程师事务所于2017年4月至12月期间完成采集。
