In order to use Planet imagery in Collect Earth you will first need to buy a licence to access Planet imagery!
You may use the Planet Explorer for a few days free of charge when you sign in just to examine the type of imagery they have available.
Once you have your access you need to setup Collect Earth to use it.

3. Go to Collect Earth, Properties->Integrated Services, **Properties->Integrated Services**, select the "Open "***Open Planet Imagery" Imagery***" and paste the API Key ion the text field:
