Our CMC Co., Ltd provides Concrete Services. We have to deliver orders in time. It is important to know exactly the direction, duration and the situation of the road (wide or narrow) when we deliver the concrete. We have to prepare to know all these situations. To prepare these we need maps. So we use GIS maps from DPS. Although there was a change about the routes, drivers didn’t have any problems as we had prepared about the routes. We didn’t need to talk about the routes although there were driver changes. After installing GPS devices from DPS, we exactly know whether drivers go the target places or not and whether they go other places that do not need. As we use GIS maps from DPS and can upload building locations on the map, we are able to memorize the data we’ve finished in Marketing. Therefore we got more trust from our clients.
