Symposium on Remote Sensing for Resources Development and Environmental Management / Enschede / August 1986 831 Urban change detection and analysis using multidate remote sensed images Chen Jun, Guan Zequn, Zhan Qinming, Sun Jiabing & Lu Hueiwen Wuhan Technical University of Surveying and Mapping, China Zheng Zhixiao The Research Institute of Urban Planning and Design of Hubei Province, China ABSTRACT:: In this paper, the methods and experiments of urban change study using the remote sensing techniques are introduced. A series of Hanyan's urban change maps were compiled after the interpretation and analysis of the sequential airphotos (1955, 1965, 1977» 1981 ). On the basis of the remote sensed data and auxiliary data, the authors have made a quantitative and qualitative analysis of the change of Hanyan's urban morphology, landscape and touristic resources in the last thirty years. The implementation of the urban master planning was also examined by comparing the sequential airphotos and urban master plans. I. Urban Change Mapping Using Multidate Airphotos The airphotos are real images of land surface at the moment of photographing. A great deal of information of urban area, such as landuse, environment, popula tion density etc., could be derived from airphotos. The relevant information of urban growth and change could also be obtained using the sequential airphotos. Four year's airphotos (table 1) are used in the detection and analysis of Hanyan's urban change and a series of urban change maps was compiled on the basis of photointerpretation and analysis. It aims mainly at representing the historical process of urban expansion and the dynamic changes of each urban element. The main contents of each map are listed on table 4* sources, urban pollution sources were also inter preted with some ground surveys. Furthermore, by comparing the urban master plans (1965» 1977) and the corresponding airphotos (1977» 1981 ), two maps were made to reflect the differences between the urban master planing and the real urban expansion (1965-1977, 1977-1981 ). II. Hanyan's Urban Change Analysis The series of urban change maps as well as the sequential airphotos are used to the analysis of urban change of Hanyan, which is one of the three cities of WUHAN. Figture 1 . gives the basic philos ophy of the study. Table 1 . The airphotos used in Hanyan's urban change detection and analysis.

Since the airphotos of 1955, 1 965 and 1977 offer a different picture of what presently existing on the ground, a special method of interpretation was considered. Considering the fact that some urban landuse types remain un changed during certain years, the photos taken several years ago were interpreted by making refe rence to the current urban landuse and the topogra phic maps and other auxiliary data. By comparing the sequential airphotos and the sequential urban landuse maps (compiled after photointerpretation), the change of different urban landuse, urban mor phology and some urban elements are easily derived and are compiled into the corresponding urban change maps.

Philosophy of urban change analysis of Hanyan using sequential airphotos. 1. Change of urban morphology and landuse . It is seen from the urban change maps that Hanyan city grew very fast. The urban area of Hanyan increased 14-81 kilometer square from 1955 to 1981. The main motive force of the urban growth is the passthrough of railway from Beijing to Guangzhou and the construction of a number of large entreprises and key projects in Hanyan. The layout of the in dustrial landuse and storehouses played an important role to the scale, formation and function of the city. As indicated in table 5, the percentage of industrial landuse and storehouses to the total urban area in Hanyan was 26.95% in 1965 and 34*65% in 1981.
