ODbL 1.0 라이선스: 상업적 사용은 허용되지만 MERIT Hydro를 기반으로 파생된 데이터는 동일한 ODbL 라이선스에 따라 공개적으로 제공되어야 합니다. 예를 들어 MERIT Hydro를 사용하여 홍수 위험 지도를 만들고 이를 기반으로 상업용 서비스를 제공하려면 OdBL 라이선스에 따라 위험 지도를 공개적으로 제공해야 합니다.
위 라이선스 약관은 MERIT Hydro를 기반으로 하는 '파생 데이터'에 적용되지만 MERIT Hydro로 생성된 '제작된 작업 / 작품'(예: 학술지 논문의 그림)에는 적용되지 않습니다. 생성된 작업이 '파생 데이터'로 간주되지 않는 경우 사용자는 아트워크의 저작권을 보유할 수 있으며 라이선스를 할당할 수 있습니다.
데이터를 다운로드하고 사용하면 사용자는 라이선스 이용약관에 동의하는 것으로 간주됩니다. 이 무료 라이선스에도 불구하고 Google은 사용자가 저자의 명시적인 서면 허가 없이 다른 웹사이트에서 원래 형식으로 데이터를 전체적으로 재배포하지 않도록 요청합니다.
MERIT Hydro의 저작권은 개발자에게 있으며, 2019년, 모든 권리 보유.
