The Level 1G (L1G) data product provides systematic radiometric and geometric accuracy, which is derived from data collected by the sensor and spacecraft. The scenes were rotated, aligned, and georeferenced to UTM map projection. Geometric accuracy of the systematically corrected product should be within 250 meters (1 sigma) for low-relief areas at sea level. The SLC-off product includes the original data gaps. Duplicated pixels have been replaced with null values (zero-fill); therefore the image contains alternating stripes of missing data. A scan gap mask is included with the final product.

The Tri-Decadal Global Landsat Orthorectified single scene data collection selection consists of approximately 9,600 Systematic Correction (Level 1G) images.
