This paper experimentally attempts to evaluate a plan for information providing system for citizens by Contingent Valuation Method (CVM). Using a pilot system on GIS including many photo images, investigators illustrated the historic heritage at Gyotoku area in Ichikawa City to provide respondents with sufficient information to evaluate the plan. The finding is that respondents acquainted with GIS express greater willingness to pay than those who are new to GIS. This paper also considers some problems for application of CVM such as overestimation and the embedding problem.
