A study on changes of slate buildings’ distribution in Korea using GIS -case study of Gang-won Province

Asbestos is classified as Group 1 carcinogen, and its use is fully banned in Korea. However, there are many slate buildings that contain asbestos, which has become a social issue. In this study, the building registers for the year 2010 and 2015 are examined to see changes in regional distribution of slate buildings in Gang-won Province. The share of slate buildings was 20.73% in 2010 and 20.77% in 2015 by the number of building, 7.46% in 2010 and 7.73% in 2015 by building area. In ratio change of slate buildings by region, Hongcheon and Hwacheon saw the biggest drop at 2.9% and 2.8% based on ratio of number while Heongseong and Cheolwon saw the biggest drop at 7.5% and 4.4% in terms of ratio of building area. These changes were visualized by using ArcGIS across cities and districts of Gang-won Province.
