Painting GCPs | Recommendations

Hello,

I need to paint over 200 targets for our upcoming project and I need some advice on what would be the best option to paint.

I’ve done some tests and it’s really hard to see from the intensity (or intensity gradient) view at 200ft AGL & 5 m/s speed.

I’m wondering if there’s a certain pattern and/or type of paint that would be more visible?

How we’ve done our paint was black and white checkerboard pattern.

This is how it looks from 100ft AGL at 2 m/s speed (low pass)

This is how it looks from 200ft AGL at 5 m/s speed (normal operating altitude)

This is the paint we used

How we painted

We need the paint to show up at 200ft agl 5 m/s speed as constantly doing low passes will really delay our timeframe.

Your advice will be greatly appreciated!

UgCS | 200 ft AGL with terrain follow at 5 m/s speed

Why so many control points ?

1,000+ acres and requirements from our client

we use something like this painted in a 4" thick chevron, and we get great visibility- we usually fly around 160’-200’ AGL.
