현재 상용화되어 서비스되고 있는 내비게이션의 맵 데이터는 유선 인터넷을 이용하여 업데이트한다. 내비게이션을 위한 모바일 단말에서의 전국 데이터는 보통 1GB ~ 2GB의 크기를 가지며 이 데이터를 유선 인터넷을 이용하여 업데이트하는데 수십 분이 소요된다. 하지만 실제 변경된 데이터는 일부분에 해당하지만 전체 맵 데이터를 업데이트함으로써 많은 비용을 낭비하게 된다. 이에 본 연구에서는 모바일 단말에서의 부분 맵 데이터를 업데이트하기 위하여 모바일 공간 데이터베이스관리시스템 개발과 이를 이용한 내비게이션 시스템 개발에 대해서 살펴보고자 한다.
