The Kaohsiung City Clean Information Real-time Query APP uses global satellite positioning system, wireless communication and geographic information technology to control the real-time dynamics of cleaning vehicles and the information of the cleaning points. Just a little bit easier to find the real-time route and timetable of the cleaning vehicle according to your location. There is no need to chase the garbage truck, and it is easy to take out the garbage~, the Kaohsiung City Cleaning Truck has been equipped with GPS satellite positioning equipment. With the built-in positioning function of the mobile device, users can search for garbage collection points within 100, 300, or 500 meters that are convenient to take out, and set them as "favorites". When the cleaning truck is about to arrive, the mobile phone receives the push broadcast, and then heads to the clearing point to take out the garbage easily~
