Abstract
This study aims to evaluate the quality of data used for GIS application through the disaster mitigation. First, we grasp the present situation of the standardization of GIS, especially the quality of data and the process of evaluating it. Next, we pick up three data, DM data of the municipality, a nation road data and a building data on the market. The accuracy of these data is tested, and numeral results about the quality of data are acquired. Finally, applying three data to some GIS applications at the same time and same condition, we find some matters caused by the difference of accuracy. And then we consider the influence of the error of data in using GIS applications for the disaster mitigation.
