Planet’s data API provides metadata in regards to image quality. This falls into two categories: standard and test. The vast majority of published imagery falls into the “standard” category, meaning that it’s passed all Planet’s image quality metrics in the processing pipeline.
The remaining published imagery falls into the “test” category. The majority test of quality images are categorized this way due to lack of ground lock. For most use cases we recommend using standard quality imagery.
You can find whether an image is standard or test quality within the scene metadata in Explorer.
