CITY INFRASTRUCTURE PLAN SUPPORTING SYSTEM

摘要

PURPOSE:To support an infrastructure plan synthetically by attaching not only the drafting function of infrastructure facility, but an infrastructure scale calculation function, an infrastructure construction expenses calculation function, and an infrastructure construction period calculation function. CONSTITUTION:A city infrastructure plan study system 1 and a data base system 2 to support the city infrastructure plan study system 1 are provided as fundamental systems. Since inputted data is held with three-dimensional coordinates, and also, a plan barometer and an original unit calculation equation required for the calculation of an infrastructure plan can be held, the calculation of the plan barometer and that of the infrastructure plan can be automatically performed based on the inputted data and the original unit calculation equation. Also, since it is provided with plural infrastructure study levels, the computation of an individual infrastructure plan and a global infrastructure plan can be performed corresponding to each infrastructure study level. In such a way, it is possible to support the infrastructure plan synthetically and also, corresponding to plan levels from that of a rough plan to that of a detail plan.
