Have a custom-tailored mapping software, with your private technical layers integrated with public worldmap. Link to autocad. Make every user maintain your data (like POIs, cable routes…), and keep your company knowledge of the field up-to-date and easily available.
Place dozens of connected sensor beacons on your staff and equipment. Report location, engine gauges... and set up alarms when maintenance is due or the sensor leaves a safe perimeter (geofencing).
