언제 어디서나 안정된 무선 서비스 제공을 받고자하는 사용자의 요구는 증대되고 국가적으로 유한된 전파자원을 경제적이며 효율적으로 이용하고 신도시 개발과 같은 국토 개발에 따른 국민들의 전파수요에 효과적으로 대처할 수 있는 전파분석 기술이 필요하다. 본 논문에서는 다양한 형태로 취득되는 영상 및 원격탐측 자료를 처리하여 전파분석의 기본 데이터로 사용되는 3차원 공간정보를 신속하고 정확하게 구축하고 건물의 높이가 다양하고 밀집되어 있는 도심지에서 적용될 수 있는 3D Ray-Tracing을 이용하여 전파분석을 할 수 있는 시스템을 제안한다. 이에 기존의 GIS데이터의 갱신주기가 길어서 발생하는 전파분석 결과의 신뢰성 저하에 대한 문제점을 Rapid Mapping 기술을 통하여 대상지역의 변화를 신속하게 추출한 후 전파분석에 이용함으로써 전파분석의 신뢰성을 높일 수 있다.
