초록

우리나라에서는 2006년부터 항공사진 촬영방식에 디지털 카메라를 도입한 이후 항공사진 촬영과 관련한 기술 패러다임이 아날로그 방식에서 디지털 방식으로 전환되고 있다. 그러나 현재 항공사진 촬영과 수치지도 제작에 대한 표준품셈은 아날로그 기반의 품셈과 디지털 기반 품셈이 혼재되어 활용되고 있다. 항공사진촬영과 관련한 품셈의 개정항목 중에서 월별천후표는 비행기의 운항일수 계산과 밀접한 관련이 있다. 현재의 월별천후표는 1999년부터 2007년 동안의 전운량 관측 자료를 이용하여 계산한 결과를 사용하고 있다. 본 연구에서는 2009년부터 2018년 동안의 전운량 관측 자료를 이용하여 월별천후표의 계산을 연구하였다. 결과적으로 29개의 동일한 지점에 대하여 신규 산출한 평균 쾌청일수는 기존의 50일에서 6일이 감소한 44일로 분석되었다. 최대 쾌청일수 감소는 진주에서 23일로 나타났으며, 최대 쾌청일이 감소한 달은 2월로 나타났다.

Since the introduction of digital cameras in an aerial-photogrammetry field on 2006, the technological paradigm related to the photogrammetry has been shifting from the analog types to digital types. However, current construction standard cost for the aerial-photogrammetry and the digital mapping are being mixed with analog-based concepts and digital-based methods. In the current standard cost, the monthly weather table is closely related to the calculation of the number of flying days in a taking of aerial photograph. The current monthly weather table uses the results calculated from the observation data of total cloud amount from 1999 to 2007. In this study, the monthly weather table was calculated using the total cloud data during ten years from 2009 to 2018. As a result, the newly calculated number of clear days for 29 stations was analyzed as 44 days decreased by 6 days. The maximum number of clear days decreased in Jinju as 23 days, and the highest decreased clearing days was February.
