Abstract
A 10-metre meshed high resolution Digital Elevation Model (DEM) has been integrated with Geographic Information Systems (GIS). High resolution DEM plays a crucial role in future GIS applications such as constructing 3D systems in Japan, but it is not sufficient for precise requirements from various applications. Also, a one-metre high resolution pansharpen image from the IKONOS satellite has been integrated with a digital map on the GIS system at the same time. IKONOS images cover 3-dimensional surfaces constructed by 10 m DEM. A precise GIS map of Kitakyushu City in Japan has been used as a digital map, which is quite accurate.
