Data product name and description

Name Description Version
Level 1C

Level 1C data products have TOA reflectance units and have been orthorectified with a moderate resolution DEM, resulting in a cartographic product with accurate geolocation.

Distribution disk files

File Name File Type Required Contents
Image File: HS*_COG.tiff GeoTIFF Yes Image data

Important notes to the user:

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