Abstract

Systems and methods for managing underground assets are disclosed. One or more computing devices may be used to receive a request for clearance to excavate including a location identifier, resolve a location based on the location identifier, and retrieve asset data corresponding to the location from an asset location database. The asset location database can include location data regarding the positions of a plurality of assets associated with a plurality of different asset owners and may be maintained by one or more updates regarding the positions of assets from computing devices associated with the different asset owners. The systems and methods can include determining if one or more assets are buried proximate the location based on the retrieved data and transmitting data related to the determination of assets buried proximate the location.
