    Web-GIS


  • About Sentinel Asia Web-GIS

  • Web-GIS is a web-based tool for easy browsing of satellite observation data or processed products with your own web browser, requiring only an internet connection. Sentinel Asia Secretariat launched the Web-GIS service for its Joint Project Team (JPT) members in November 2019 and continues to operate the service.
