Get an account:
With an account you get access to the following data:
We have access to a small amount of SkySat (.5m resolution) imagery (current and archival). Contact email@example.com to discuss your project and data availability. PlanetScope imagery are available at a 3m to 5m resolution depending on location.
Our subscription includes full access to the Orders API.
Accounts include an annual download quota of 10,000 km2. If you reach the quota, email us and we'll let you know if we can increase it. Note that certain imagery, such as Landsat, MODIS, etc. are available from the free sources listed below and we recommend using these sources instead of Planet so you don't use your quota.
