Abstract: This presentation will discuss the work flow and common data sources of background information that can be used to streamline the buried hazard mapping project decision process, focus the project planning effort, and optimize the results from the field effort. Case history summaries will be used to support the concepts presented. The discussion will also examine ways to supplement client supplied spatial data with information available from local, state, and national GIS repositories.
