초록

지난 2012년부터 도로명주소가 본격 시행 및 활용되고 있지만, 아직도 상당 부분에서는 기존의 지번주소가 많이 통용되고 있다. 이는 일반인들의 공간 인식체계와 도로명주소의 공간 구조화 방식의 간극으로 인한 문제이다. 따라서 도로명주소 기반의 공간 인식 체계가 자리잡기 위해서는 생활 속에서 활용되는 각종 공간정보들이 도로명에 의하여 주소정보를 부여받을 수 있어야 한다. 본 연구는 공간 인식 과정이 가장 중요하게 나타나는 길찾기 과정에서의 도로명주소 체계의 연계를 목적으로, 이를 위하여 필요한 공간데이터의 기하학적 매칭 방법론을 설계 및 구현하였다. 도로명주소 기본도의 도로구간 레이어와 보행자용 도로 네트워크에 대하여, 개별 도로 객체를 중심으로 네트워크 이웃을 생성하였다. 그 다음, 생성된 이웃 집합 간의 기하학적 유사도 비교를 통하여, 네트워크 데이터의 각 객체에 매칭되는 도로구간을 탐색하였다. 매칭 성능은 F0.5 값을 기준으로 0.936의 결과를 얻었으며, 유사도 값을 기준으로 10% 수동 검사를 수행한 결과 이 값을 0.978까지 향상시킬 수 있었다. 이렇게 생성된 매칭 대응관계를 이용하여, 보행자용 도로 네트워크 데이터에 도로명 정보를 부여하였다. 이러한 방법론을 통하여, 도로명주소를 기반으로 한 길찾기 서비스 제공 및 공간 인식체계 정착에 도움을 줄 수 있다.

The road name address system has been in effect in Korea since 2012. However, the existing address system is still being used in many fields because of the difference between the spatial awareness of people and the road name address system. For the spatial awareness based on the road name address system, various spatial datasets in daily life should be referenced by the road names. The goal of this paper is to link the road name address system with the wayfinding process, which is closely related to the spatial awareness. To achieve our goal, we designed and implemented a geometric matching method for spatial data sets. This method generates network neighborhoods from road objects in the 'road name address map' and the 'pedestrian network data'. Then it computes the geometric similarities between the neighborhoods to identify corresponding road name for each object in the network data. The performance by F0.5 was assessed at 0.936 and it was improved to 0.978 by the manual check for 10% of the test data selected by the similarity. By help of our method, the road name address system can be utilized in the wayfinding services, and further in the spatial awareness of people.
