I am working with satellite imagery processing.

I'm using this service to search for some objects in the US:

https://search.descarteslabs.com

Can I export about 1k results, for example, to KML or CSV/TXT with geographic coordinates?

Or, maybe, there are other services for finding some objects on satellite imagery (area of the US) with a possibility to save/export results of this searching.

This is possible, with caveats (full disclosure, I am a Descartes Labs employee).

  • Geovisual Search is not part of the Descartes Labs Platform and any results you collect via the site are subject to the Descartes Labs website Terms of Service.

  • Geovisual Search is an index of visual similarity - not a model trained to find specific objects or patterns. For the complete methodology, see this publication.

That said - each search of the index returns 1000 results ordered by similarity within the index. This is served by a JSON API at https://search.descarteslabs.com/search?key={key}&{layer}&limit={limit} where key is a UTM DLTile identifier, layer is an identifier for the dataset indexed, and limit is the number of results to return.

If all you need is a the list of tiles returned on the left - you can get that JSON response by looking in your browser's developer console to find the request made by the API. The result will be a list of GeoJSON features, with a distance property that corresponds to the visual similarity relative to the key tile (lower is more similar). This will include 1,000 results by default:
