Our Company distributes Tea Leaf (lahpet) and various kinds of crunchy beans. When we distribute our goods, we have some doubts; did our delivery vehicles actually reach the destination? did they really reach the target place in time? did they go any unnecessary places? Then we decided to purchase and install GPS devices from DPS. It makes me calm after we did that. The speed is very important for our delivery vehicles when we send them rural areas because our delivery vehicles are big and we want to make sure not to be dangerous. After installing the devices, we get the alarm if drivers drive over speed. As we also used GIS maps from DPS, we have got the idea of how to expand our distributions after uploading the location of our distribution shops on the maps. It is very helpful because we can make the route for our sale teams and can continuously take ground information.
