ABSTRACT: DGT Associates has been integrating ArcGIS into it's Subsurface Utility Mapping (SUM) workflow in order to increase efficiency and quality of data collected. Accurately mapping underground facilities is most challenging due to the simple fact that they are typically not observable. The path to delivering the most accurate portrayal of the subsurface environment requires a combination of research and various field work investigation techniques. DGT's SUM team has found ArcGIS to be beneficial in all phases of the process. Georeferencing plans in ArcMap helps the team "set the stage" before commencing data collection work in the field. Often times, a wide variety of plans from multiple sources, of varying accuracies, are required on a single project. ArcMap helps keep the plans organized and identifies areas of concern. While in the field, Collector is used to survey the data and populate crucial attributes. After completion of the field collection, the resulting data can be analyzed, shared and viewed in various formats, helping us meet the needs of the end user.
