Extraction of Heavy Snowfall Vulnerable Area for 3 Representative Facilities Using GIS and Remote Sensing Techniques

Abstract

This study is to analyze the heavy snowfall vulnerable area of snow load design criteria for greenhouse, cattle shed and building using ground measured snow depth data and Terra MODIS snow cover area(SCA). To analyze the heavy snowfall vulnerable area, Terra MODIS satellite images for 12 years(2001–2012) were used to obtain the 2014년 10월 20일 접수 Received on October 20, 2014 / 2014년 12월 4일 수정 Revised on December 4, 2014 / 2014년 12월 31일 심사완료 Accepted on December 31, 2014 * 이 논문은 2010년도 정부(미래창조과학부)의 재원으로 한국연구재단의 지원을 받아 수행된 연구임(NRF2010-0029194). 1 건국대학교 사회환경시스템공학과 Dept. of Civil & Environmental Systems Engineering, Konkuk University 2 한국수자원공사 K-water 연구원 수자원연구소 Water Resources Research Center, K-water Institute, Korea Water Resources Corporation ※ Corresponding Author E-mail : kimsj@konkuk.ac.kr Extraction of Heavy Snowfall Vulnerable Area for 3 Representative Facilities Using GIS and Remote Sensing Techniques 2 characteristics of snow depth and snow cover areas respectively. By comparing the snow load design criteria for greenhouse(cm), cattle shed(kg/m2), and building structure(kN/m2) with the snow depth distribution results by Terra MODIS satellite images, the facilities located in Jeolla-do, Chungcheong-do, and Gangwon-do areas were more vulnerable to exceed the current design criteria.
