Open Data Cube (ODC)

An open source geospatial data management and analysis software project. It is a global initiative to increase the value and use of satellite data by providing users with access to free and open data management technologies and analysis platforms.

At its core, ODC is a set of Python libraries and a PostgreSQL database that allows you to work with geospatial raster data.

Operational Land Imager (OLI)

The Operational Land Imager is carried by the Landsat 8 satellite. It measures in the visible, near infrared, and short wave infrared portions of the spectrum. Its images have 15-meter (49 ft.) panchromatic and 30-meter multi-spectral spatial resolutions along a 185 km (115 miles) wide swath.

Operational Land Imager 2 (OLI2)

The OLI-2 instrument is carried by the Landsat 9 satellite. It provides visible and near infrared / shortwave infrared (VNIR/SWIR) imagery consistent with previous Landsat spectral, spatial, radiometric and geometric qualities.

The OLI-2 instrument includes an optical telescope, Focal Plane Array / Focal Plane Electronics (FPA/FPE), calibration hardware, and instrument support electronics. OLI-2 provides data for nine spectral bands with a maximum ground sampling distance (GSD), both in-track and cross track, of 30 m (98 ft) for all bands except the panchromatic band, which has a 15 m (49 ft) GSD.
