Disaster prevention GIS (geographic information systems) up to the present often use expensive commercial-use GIS engines when displaying information on a map, but there are many cases where simple map display functions alone are used and skillful use of the bountiful functions of the commercial-use GIS engines is not required, and benefits commensurate with the cost of these engines are not achieved.

To deal with this problem, there is a method of constructing a disaster prevention GIS system for a low price using a GIS engine which is open source software (OSS). JRC has developed a disaster prevention GIS system using MapServer which is an OSS GIS engine that has performed well in many situations, and its method of construction is introduced here.
