Alaska’s Source Group plant verification is the process of physically inventorying network elements.
This process is often used when lack adequate plant records, for one reason or another, verification can be as basic as evaluating the condition of pedestals, hand holes, and poles, or can be a thorough, in-depth review of cable sizes, counts, assignment records, circuit records, pole attachments, central office equipment, remote cabinet inventory, and customer premise equipment. 
Plant verification can also include pinpointing exact locations of network elements by using GPS technology.
This enables plant records to be integrated with other land base and utility information from local city and county governments, as well as State and Federal GIS information.
The availability of GPS coordinate information can also assist with locating network facilities during emergency response requirements, adverse weather conditions or at night.
Alaska Source has been actively using GPS and we regularly upgrade our equipment to take advantage of the latest advances in technology.
We have performed plant verification and GPS data collection throughout Alaska and its territories. 
In addition to plant verification, our GPS crews are actively involved in acquiring data for right-of-way permits, and for as-built documentation of newly placed facilities
This process all begins with evaluating the condition of pedestals, locating the facilities such as hand holes, and poles, or can be a thorough, in-depth review of cable sizes, counts, assignment records, circuit records, pole attachments, central office equipment, remote cabinet inventory, and customer premise equipment.
