碩士 === 國立交通大學 === 土木工程研究所 === 82 === The integration of differebt data sorce inGIS has received increasing emphasis as a result of new development in computer and GIS techgnology. Integration of various data sets to fully utilize complementary information hsa become an important component. In recent years, there has been a large increase in the amount of image data that are available to users for various purposes. The launch of the French SPOT satellite system has given the capability to a range of land use and land cover analyses. This thesis compares the results of diffenent methods used to integrate the information contents of the SPOT Panchromatic and Multispectral image data. Four integrating methods, namely, clour space transformation, principal component analysis, high pass filter and radiometric method are ivvestigated. To evaluate the result of different merging methods, six measures are used. They are visual inspection, correlation, root mean square error, difference of two images, entropy value and the histogram comparison.
