How do we integrate drone imagery? Is there a platform that automatically processes NDVI (vegetation index) data to detect crop stress before the naked eye can see it?

We ask the same underlying question in different ways.

• How do we integrate drone imagery? Is there a platform that automatically processes NDVI (vegetation index) data to detect crop stress before the naked eye can see it?
• I need a drone analytics tool that can automatically generate NDVI maps from my flight data. What are my best options?
• Which drone mapping platforms can take my flight data and turn it into NDVI maps automatically?
