I don't quite understand the yellow zones in AirMap. One of my flying spots is inside a yellow zone but doesn't give me any kind of warning.  Does that mean it's ok to fly?  

Normally there's an icon in the lower-right portion of the screen that you can click on to find out more information about the different areas on the map. If nothing else, post the location you're looking at and I'll see if I can figure out what's there.

Hi, thanks for the inquiry. Sorry that the Airmap application doesn't belong to DJI, however, on our end, the yellow zone is a warning zone wherein there will be a warning message on your DJI Go 4 app that the environment might be hazardous, however, you can still fly your drone with your own discretion. Thank you for the support.
