| Abstract | The study focuses on the integration of remote sensing with Geo-lnfo1mation System for land-use change analysis. The Pathum Thani province -- one of the most dynamic areas in Thailand -- was chosen as a case study. The available land-use data and socio-economic records were collected and input into GIS database. The satellite images of MSS1986, SPOT1989, TM 1990, TM1992 and SPOT1993 were analyzed within digital image processing system in conjunction with GIS, which gives satisfactory classification accuracy -- 87 % overall accuracy on SPOT date 1993 classified image. The post-classification comparisons of classified images were conducted to derive the land-use change maps. The developed land-use database was updated by converting the classified images in raster format into vector GIS. The land-use database management and statistical and spatial analysis were done to study the land-use dynamics of the study area during 23 years (1970-1993). The three most important land-use categories -- built-up areas, fruit-tree plantation and paddy land -- were analyzed together with the socio-economic factors. The univariate analysis provides the trend of paddy loss, fruit-tree plantation and built-up areas expansion over time. The multivariate analysis reveals the close relationship between road network development and expansion of built-up areas, and the relationship between irrigation density and plantation cultivation. As a result of factor analysis, the built-up expansion plays a more important role than fruit-tree expansion in socio-economfo life of the study area having more impacts on population growth, on increasing the female labour in the industrial sector and other aspects. The spatial analysis provides the u·end surfaces of the expansion of built-up areas, road network and fruit-tree plantations that help analysts understand the spatial distribution of the changes. The integrated GIS/image processing system incorporating with the statistical package applied in defining land-use dynamics in Pathum Thani case proved very effective. The applied methodology is recommended for land-use change analysis of other areas. |
