What does a "processing unit" mean?

Home > Faq > What does a "processing unit" mean?

A processing unit (formerly named "request") stands for a tile of 512*512 px, which is a recommended option for integration in web application due to best performance/size ratio.
200.000 requests per month limit therefore means that you can retrieve 200.000 tiles of 512*512px per month from our service. If you ask for smaller tiles, e.g. 256*256px, the volume of requests is proportionally larger. Similarly, if you ask for large tiles (e.g. 2000*2000 px), it is smaller. 

What does generally not count:

  • WFS requests used to retreive information about available dates in the area.
  • Requests, which result with error/warning rather than the data (e.g. requesting data over the area/time, where there are none, etc.)

Statistical API requests over long time-range can count as multiple processing units (e.g. as many as there are available scenes in the defined time range).

Multi-temporal API requests over long time-range can count as multiple processing units (e.g. as many as there are available scenes in the defined time range).

In case request take more than 3 input bands, it is counted proportionally larger - e.g. 13 bands = 13/3 = 4.33 factor
