“UAV technology allows us to view the landscape from an elevated perspective”
It gives us information that may not just be difficult to determine from ground level but, may well be impossible.

What do we use?
• A digital camera
![Page 15: UAV's in Agriculture](https://reader034.vdocuments.net/reader034/viewer/2022042906/589ac39f1a28abcf058b58d5/html5/thumbnails/15.jpg)
Accuracy of Data
• Accuracy depends on
– Image resolution
–GPS quality and accuracy
–Camera position and time
–Ground control points
–Flight Planning

Post Production
• Raw Data
• Computing power or “Cloud”
• Finally – the end product
–Actual data we can use
