1. A system ( 20 , 20 ′) to monitor drilling rig activity and to provide and manage drilling rig information, the system ( 20 , 20 ′) comprising a communication network ( 22 ), and at least one computer defining a drilling rig information management server ( 24 , 24 ′) positioned at a data center in communication with the communication network ( 22 ) to provide user access to drilling rig information, the drilling rig information management server ( 24 , 24 ′) including a processor ( 30 ) and memory ( 26 ) in communication with the processor ( 30 ), the system ( 20 , 20 ′) being characterized by: a rig information, database ( 38 , 38 ′) accessible to the processor ( 30 ) of the drilling rig information management server ( 24 , 24 ′) and including drilling rig activity data containing drilling rig location data for a plurality of drilling rigs; drilling rig information management program product stored in the memory ( 26 ) of the drilling rig information management server ( 24 , 24 ′) and including instructions that when executed by the processor ( 30 ) of the drilling rig information management server ( 24 , 24 ′) cause the server ( 24 , 24 ′) to perform the operations of: retrieving drilling rig location data from the database ( 38 , 38 ′) responsive to user selection of a geospatial location attribute, accessing digital mapping data to display a digital map associated with the user selected geospatial location attribute, and providing data to display indicia of a drilling rig location for at least one drilling rig overlaid upon and spatially oriented to at least portions of the digital map.
