This data set contains 21 L1-calibrated scenes from the OLI multispectral onboard the Landsat 8 NASA mission. All scenes are 7 bands (bands 1-7 from the OLI) and cropped to a standardised 4096x4096 size, stored as raw 16-bit unsigned integers, in little endian byte order and in band-sequential (BSQ) order. This data was collected over a varied range of locations around the world between 2013 and 2021 and were obtained from the Landsat 8 data repository in Google Cloud https://console.cloud.google.com/storage/browser/gcp-public-data-landsat/LC08/01?pageState=(%22StorageObjectListTable%22:(%22f%22:%22%255B%255D%22))&prefix=&forceOnObjectsSortingFiltering=false&rapt=AEjHL4Oce-7moqNK0g-5W2KKn-HKYkqfOXCTQ3ePOb3rAtTcz6OZt0TrkBXJA-CPjkXDIEyq94o6f5twpjgM_mqoYjzJcbewKXbFZsYnxXALXFVofiSO6gY. Specific dates and locations of each scene may be identified using the ID code in the scene name. These scenes compose a test set to evaluate compression algorithms for multispectral data.

METHODOLOGICAL INFORMATION 1. Description of methods used for collection-generation of data: OLI is a push-broom sensor with a four-mirror telescope and 12-bit quantization. OLI collects data for visible, near infrared, and short wave infrared spectral bands as well as a panchromatic band. 2. Methods for processing the data: The panchromatic band (8) and band 9 are discarded. No further preprocessing is done.
