Capella CSI Product Bundle File Structure

Capella's CSI product includes a five-file bundle with GeoTIFF previews, metadata, and integrity files for full user control and quick viewing.

Capella’s Colorized Sub-aperture Image (CSI) product is delivered using the same five-file bundle that is available for download for the SLC, GEO, & GEC products:

  • One cloud-optimized GeoTIFF Preview Image
    • The Preview is a smaller file size and the colorization is pre-balanced for quick viewing. This file is displayed on the Capella Console. 
  • One cloud-optimized GeoTIFF Image Data File 
    • The Image Data File is ready to be manipulated by the user in geospatial software to accentuate certain features.  
  • One STAC metadata file in JSON format
  • One extended metadata file in JSON format 
    • The extended metadata includes timing and colorization information for the sub-apertures used in the CSI product.
  • One data integrity digest file in JSON format

 

The naming convention of each file type is shown in the screenshot below:

The structures and fields of the cloud-optimized GeoTIFFs and metadata files are described in detail in Capella’s SAR Products Format Specification. The Digital Signature Digest File is also described separately.
