INFORMATION TO USERS This manuscript has been reproduced from the microfilm master. UMI films the text directly from the original or copy submitted. Thus, some thesis and dissertation copies are in typewriter face, while others may be from any type of computer printer. The quality of this reproduction is dependent upon the quality of the copy submitted. Broken or indistinct print, colored or poor quality illustrations and photographs, print bleedthrough, substandard margins, and improper alignment can adversely affect reproduction. In the unlikely event that the author did not send UMI a complete manuscript and there are missing pages, these will be noted. Also, if unauthorized copyright material had to be removed, a note will indicate the deletion. Oversize materials (e.g., maps, drawings, charts) are reproduced by sectioning the original, beginning at the upper left-hand comer and continuing from left to right in equal sections with small overlaps. Photographs included in the original manuscript have been reproduced xerographically in this copy. Higher quality 6" x 9" black and white photographic prints are available for any photographs or illustrations appearing in this copy for an additional charge. Contact UMI directly to order.

ACKNOWLEDGEMENTS I wish to express my sincerest gratitude to my major professor, Dr. Nina Lam, for her guidance, support, patience, confidence and encouragement during the entire course of my Ph.D. studies. I wish to express my appreciation to the other members of my graduate committee, Dr. Adrian, Mr. Braud, Dr. Huh, Dr. Leitner, and Dr. Liu, for their guidance and comments in the dissertation research. I would like to acknowledge Mr. Braud, in providing the Landsat TM data used in the experimental study. I would like to thank Dr. Qiu for providing suggestions and encouragement in the research. I appreciate the efforts of Mr. Bryant who reviewed the draft manuscript and made helpful editorial comments. I also thank fellow graduate students in the Computer Mapping Sciences Laboratory and Department of Geography and Anthropology for numerous fruitful conversations. In particular, Zuju Yao, Xiongping Zhang, Weiweng Feng, Ke Xiao, Jane Read, Michael Daniel, and Dennis Nicholas together with the faculty, staff, and other students, have made LSU an exciting place to conduct geographic information systems and remote sensing research. This dissertation could not have continued without the constant love, encouragement and support of my parents through the course of my education. Special thanks are due to my wife Weihong Zhu for her continual understanding and sacrificing, her hard work keeping us both on track to study together, and especially for bringing our daughter Julia into the world. ii Reproduced with permission of the copyright owner.
