The tools of the trade have been the same since anyone can remember. In addition to binders full of paper maps and forms, each crew would bring the GPS gear. Typically, GPS kits could cost up to $70,000 per crew. While the hardware costs were high, the customer required sub-meter accuracy and these were the trusted tools to deliver that accuracy.
Like the gear, the workflow had always been the same. Each day the crew would collect the data, and then return to the hotel where they would upload and post-process the data. Then office staff would examine the data for anomalies and corrections, dispatching crew to recapture data where needed and eventually delivering static reports to the customers. And if it ain’t broke, don’t fix it.
