Catalog ID

The Catalog ID is the vendor's identifying information for the acquisition data collected by the satellite. This is sometimes referred to as the "acquisition ID." The catalog ID for the acquisition is also displayed in the properties for products derived from that acquisition. The catalog ID is used to place an order for a product.

Example Acquisition Catalog ID: 1020010007AF7100

Product ID

For a DigitalGlobe product, the "identifier" field is the product ID.

The format of the product ID is:

<catid>_<part>_<band comb (MSI, PAN, SWR)>_<soli>

Example: 10300100301DCE00_P002_MUL_055825267010.

In this example:

Component Value
catid 10300100301DCE00
part 002
band combination (MSI, PAN, SWR)
soli (sales order line item) 055825267010

S3 location

s3://bucketName/bucketPrefix/File name

The bucketName, bucketPrefix, and file name can all be found in the response body for a DigitalGlobeProduct.
