External Geolocation for Swath DataSwath products (called Level 1 and Level 2 by NASA) are in the original instrument geometry (not gridded). Geolocation information is needed for remapping but also understanding the product. Geolocation data can be as large or larger than some L2 products. Storing this information in each L1/L2 product increases archive volume and for users who work with multiple products, the information would be duplicated. In this talk, MODIS is used as an example –other satellite and aircraft instruments have similar issues.
