In one aspect, the present invention relates to a drilling-information-management system. The drilling-information management system includes a probe assembly disposed on a drill rod, a first computer interoperably coupled to the probe assembly via a conductor disposed in a drill rod, and a second computer in communication with the first computer. The second computer includes a barcode scanner. The drilling-information management system includes a database in communication with the second computer. Drilling-project data is transferred from the database to the second computer and calibration data is transferred from the second computer to the first computer. The first computer executes a drilling plan according to the drilling-project data.
