I would like to download Planet 3-month mosiacs using the RestFUL API, but I'm not sure what to specify for the item_type. The documentation here https://developers.planet.com/docs/api/items-assets/#assets lists a bunch of item types but they seem to be individual tiles.

Is it possible to use Planet's API to download 3 month mosaics, and if so, how?

  • By the way, I see a very similar question posted here with no response: gis.stackexchange.com/questions/300156/…, Planet suggests that user support be posted on this stackexchange with the tag [planet] which is why I'm posting this question.

FYI for anyone else who might run across this in the future. I directly contacted someone at Planet and they reported what I was experiencing was a bug. They also promptly fixed it and the following query format now works:

curl -L -H "Authorization: api-key [redacted]" https://api.planet.com/basemaps/v1/mosaics

If you want to download basemaps, you can use the Basemaps API: https://developers.planet.com/docs/api/reference/#tag/Basemaps-and-Mosaics

  • So I did that, like this: curl -L -H "Authorization: api-key [redacted]" https://api.planet.com/basemaps/v1/mosaics and I get back an empty list of mosaics. Does this mean my API key does not have access to Planet mosacis?

  • Yes, that's right. This is a "contact sales" moment, but there's also a limited trial: planet.com/basemaps-trial Apr 17, 2019 at 19:13
  • Thanks @patrick-armstrong, I did contact sales and they reported what I was experiencing was a bug which they promptly fixed.
