It spends much manpower and time to get the information. The improving technology of digital photogrammetry and geographic information systems can assist investigate and collect the information. The objective of this research has been to analyze the land use intensity with assistance of geographic information systems and digital photogrammetry. Digital aerial photographs have been used to collect 3-D spatial information of research area. This information has been imported into a geographic information system. Building coverage ratio and building bulk ratio of whole research area could be established thereafter. The information collected by digital photogrammetry has also been investigated and checked in situ. The results have indicated that: 1.The ratios of both building coverage ratio and building bulk ratio to the original planned record have been of 1.1~1.2. 2.The most suitable height of each floor is 3.3m when calculating the floor number of building in the research area. 3.Digital aerial photographs could be very useful when the information of land use intensity was required.
