Dumpster container and garbage truck
Mobile app where garbage truck operators know where and if dumpster containers, spread throughout the city, are empty, half empty or full so they know if they should make the trip to pick them up.
They should be able to note this on the app on their cell phones or ipad so the rest of the operators and main office, can view the information on real-time.
Google Maps, GPS integration is also needed to see what is the truck location at any given time.
Optional features: Internal messaging.
