The new ALI product represents an effort to increase the quality and usability of the current ALI data products available from EO-1. The previously available ALI image product was limited to radiometrically corrected (Level 1R) data with no geometric correction or georeferencing applied. The Level 1R image was provided in four separate files, or "strips," each of which corresponded to one of the sensor's four individual sensor chip assemblies. Each band within the new Level 1Gs product will be geometrically corrected and assemblies will be stitched together to provide a single mosaicked image file.

ALI is a 30-meter multispectral sensor with spectral band ranges and spatial resolutions very similar to the Landsat 7 Mapper Plus (ETM+). The L1Gs ALI product will include nine 30-meter bands in the VNIR and SWIR ranges and a 10-meter panchromatic band.
