EROS Data Products
ALI data have the following levels of correction: Level 1R is radiometrically corrected with no geometric correction applied. The image data are provided in 16-bit radiance values. The data are available in Hierarchical Data Format (HDF) and is distributed on CD-ROM, DVD, and File Transfer Protocol (FTP). Level 1Gs is geometrically corrected and provided as a single 'stitched' file. The image data are provided in 16-bit radiance values. The data are available in HDF or Geographic Tagged Image-File Format (GeoTIFF) and is distributed on DVD and FTP.
Level 1Gst is terrain corrected . in HDF or GeoTIFF and is distributed on DVD, and FTP 5

Pan-- Sharpening Pan
Pan Sharpening • Pan sharpening is a process by which the resolution of multispectral thematic data is artificially increased by using intensity values from higher resolution panchromatic data. • The panchromatic intensity data may be a derived data set or an “as collected” raster. • Pan sharpening allows merging data from different sensors.
