2       Data Collection

2.1 Data Source

Data that I used for my project were acquired from the department of Geography at Yonsei University, Korea.   Although my originality is Korean and my primary language is Korean, I found the data acquisition process very challenging since I could not figure out who the right contact is, and I had to make all contacts only through email.  It took a lot of time and energy to find the right contact person, and through lab web page, I finally found that Dr. Kim who had and eventually provided me the data I needed.  I had to write a very long description of this project in order to acquire the data because Dr. Kim had initially refused to send any data out of the department of Geography at Yonsei University unless he understands specifically what I was planning to do.  It took me almost ten days to get his approval and access code to search the data stored at the lab database.  After acquiring the data, another difficulty that I faced was the various formats of data. Since the data were in many different formats, some I never seen before and some that are hardly used in North America, finding data conversion applications, making the conversion, and screening the data for its usability took me considerable amount of time.  After struggling with data for several days, I gathered enough data to determine the susceptibility to landslide of this particular region where disastrous landslides occur regularly every year during the raining season.
