Data product name and description

Name	Description
Level 1C	The Level-1C product (previous refered to as Level-3A) is a high-quality, pre-processed satellite image that has undergone significant radiometric and geometric corrections. The data is provided as Top-of-Atmosphere (TOA) reflectance, which corrects for variations in sensor sensitivity and sun angle, and is orthorectified to ensure geographical accuracy.
Level 2A	The Level-2A product is similar to L1C product, but values have been converted to surface reflectance.

Important notes to the user:

The GDB support of GRUS-1 data products is read-only.
GDB uses the above file names to identify the data product type. Therefore, to preserve compatibility with GDB, the file names must not be altered when the data is copied to another location.
To load the data set, select the metadata (.json) file.
