Data Sources

  • Landsat 5

    Landsat 5

    Landsat 5 was a low Earth orbit satellite launched on March 1, 1984 to collect imagery of the surface of Earth. A continuation of the Landsat Program, Landsat 5 was jointly managed by the U.S. Geological Survey (USGS) and the National Aeronautics and Space Administration (NASA). After 29 years in space, Landsat 5 was officially decommissioned on June 5, 2013. The Thematic Mapper (TM) sensor of Landsat 5 has seven spectral bands at 30 m, including a thermal band at 120m. Nowadays, the exploitation of the multitemporal satellite data from Landsat 5 allows us to perform robust time series analysis, examine natural phenomena, develop accurate predictive models and many more applications.

  • Landsat 8

    Landsat 8

    Landsat 8 is an American Earth observation satellite launched on February 11, 2013. It is the eighth satellite in the Landsat program. Originally called the Landsat Data Continuity Mission (LDCM), it is a collaboration between NASA and the United States Geological Survey (USGS). Landsat 8 data are an ideal source for applications related to: agriculture, forestry, land use monitoring, mapping, hydrology, environmental monitoring etc. Landsat 8 has eight spectral bands with spatial resolutions ranging from 15 to 60 meters and with temporal resolution of 16 days.

  • Sentinel 2 (Coming Soon)

    Sentinel 2 (Coming Soon)

    The Sentinel-2 satellites are the European Space Agency mission, part of the Copernicus program. Sentinel-2 is a land monitoring constellation of two satellites that provide high resolution optical imagery data. The mission provides a global coverage of the Earth's land surface every 10 days with one satellite and every 5 days with 2 satellites, making great use of data in on-going studies. The satellites are equipped with the state-of-the-art MSI (Multispectral Imager) instrument, that offers high-resolution optical imagery, which allow accurate monitoring and mapping of different types of vegetation, soil and water cover, land use and change monitoring, natural hazards assessment, etc. Sentinel 2 has a set of 13 spectral bands spanning from the visible and near infrared to the shortwave infrared, featuring four spectral bands at 10 m, six bands at 20 m and three bands at 60 m spatial resolution.
