Mountain Mapping and GIS employs Certifed Trimble trainers, who are highly experienced data collection technicians and who are also skilled teachers. In keeping with the rigorous requirements of the Trimble Certified Training program we may only offer these courses in collaboration with one of a select group of Trimble Dealers. These dealers can offer you a full range of GPS and ancillary equipment, and can arrange for a MMG trainer to teach your staff.
