Abstract
This study evaluates the completeness and positional accuracy of the OpenStreetMap (OSM) road network in four districts of Hwaseong Special City by comparing it with the official road network provided by the National Geographic Information Institute (NGII). The 2025 OSM Korea PBF data and the official road network data were transformed into the same coordinate system, and district-level analyses were conducted using total road length-based completeness, spatial distribution of missing roads, RMSE, and 5 m and 10 m buffer-based positional matching rates. The results show substantial regional variation in completeness: Dongtan District recorded 137.93%, Byeongjeom District 99.37%, Hyohaeng District 68.75%, and Manse District 56.33%. Positional accuracy was generally favorable, with RMSE values ranging from 2.02 to 4.41 m. However, the completeness value exceeding 100% in Dongtan District should be interpreted as a relative result caused by differences in road-type coverage, including footways, cycleways, and service roads in OSM. This study highlights the potential for complementary use of public road network data and OSM.

본 연구는 화성특례시 4개 권역을 대상으로 OpenStreetMap(OSM) 도로망의 완성도와 위치 정확도를 국토지리정보원 공식 도로망과 비교하여 평가하였다. 2025년 OSM Korea PBF 자료와 공식 도로망 자료를 동일 좌표계로 변환한 뒤, 총연장 기반 완성도, 누락 도로의 공간분포, RMSE 및 5m·10m 버퍼 기반 위치 일치율을 분석하였다. 분석 결과, 완성도는 동탄구 137.93%, 병점구 99.37%, 효행구 68.75%, 만세구 56.33%로 권역별 차이가 컸으며, 위치 정확도는 RMSE 2.02~4.41m로 전반적으로 양호하였다. 다만 동탄구의 100% 초과 완성도는 분석에서 이용한 OSM과 공식 도로망 간 도로 유형 포함 범위의 차이에 따른 상대적 결과로 해석할 필요가 있다. 본 연구의 결과는 공식 도로망과 사용자 참여를 통해 작성한 OSM 도로망 간의 상호 보완적 활용의 가능성을 제시한다.
