It is impossible to call in the cost of map-production from the supply cost because the map produced in NGI is the public property. The aims of this research are to calculate a map manufacture cost and to assess the reasonable map prices with considering public property of map. For these aims, We have calculated the cost according to the scale and the form of paper and digital map, have determined the map supply cost, and have analyzed the situation of map supply and the map circulation market. We propose two alternatives. Firstly, supply price of map is reached the goal price after 6-years(raising ratio 30%) and Secondly, supply price of map is reached the goal price after 3-years(raising ratio 50%) because map supply price raising ratio is very much if research results are reflected after 1-year.
