최근 SNS 시대, 모바일 혁명, IoT 활성화 등으로 인해 컴퓨터가 처리해야 할 데이터의 절대적인 양이 급증하고, 아울러 이전에는 크게 중요하지 않다고 판단하여 무심코 버렸던 거대한 양의 데이터로부터 빠른 시간 내에 가치 있는 정보를 추출할 수 있는 신기술이 출현함에 따라 빅데이터의 시대가 도래하게 되었다. 이러한 빅데이터는 모든 종류의 데이터가 포함될 수 있으며, 기본적인 문자 데이터로부터 수치/통계, 영상/이미지, 센서, 위치/공간 데이터에 이르기까지 수 많은 종류의 데이터를 포함할 수 있다. 본 고에서는 이러한 빅데이터 중에서도 데이터 자체의 다양성 및 복잡도가 매우 높고, 대용량의 볼륨을 형성하여 다양한 분야에 대한 활용 가능성이 높아 실시간 변화하는 동적 데이터의 특징을 동시에 보유하고 있는 공간 빅데이터에 대한 국내외 정책, 시장, 기술 동향에 대해 살펴보고자 한다. 끝으로, 이러한 각 동향 분석 결과를 기반으로 미래 공간 빅데이터 기술 개발의 방향성을 미리 제시해 보고자 한다.
