Stormwater - Pipes

Outlets 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 and is updated by County staff as needed.本次野外采集的暴雨排水口点位均位于博尔德县公共卫生部暴雨排水系统（MS4）地理信息系统绘图项目的作业区域内。数据采集使用Trimble Geo-XH 6000型GNSS接收机，其经事后差分处理后的水平定位精度可达2.5厘米（0.98英寸）。数据通过博尔德县境内及周边的基准站完成事后差分处理。本次数据采集所使用的数据字典，系与博尔德县公共卫生部项目负责人协同开发而成。该数据集于2017年4月至12月间由安德森咨询工程师公司（Anderson Consulting Engineers）采集，并由博尔德县工作人员按需更新维护。
