There are two high-level categories of assets in any event: pre- and post-event imagery. I'll use the post-event imagery for Nepal for this walk-through.
In the folder listings for either pre- or post-event imagery, there will be an items.parquet file. Clicking the filename will bring up a webpage describing its contents, but next to the filename is a link that you can access from the command line and/or DuckDB, without Cloudflare blocking your client.
The following will download the 83 KB Parquet-formatted, post-event metadata file for the flash-flood disaster in Nepal last month.
$ wget -O nepal.post.parquet \ https://data.source.coop/planet/disasterdata/nepal-flash-flood-2026-08-26/post-event/items.parquet
There are 24 records in this file.
SELECT COUNT(*) FROM 'nepal.post.parquet';
This is an example record.
$ echo "FROM 'nepal.post.parquet' LIMIT 1" \ | ~/duckdb -json \ | jq -S .

These are the numbers of unique values for each field in the properties structure. I've excluded structures and lists.
These are the highest and lowest resolutions of the imagery captured, broken down by constellation.
The images have been published as quickly as 1.4 hours after being captured.
These are the locations of the footprints in relation to the whole of Nepal and southern China.
The imagery has been captured at different times and, in some cases, overlaps with other imagery that has already been collected.
