Golf Course Superintendent Using Greensight to Fine Tune Sand Topdressing Applications

I’m sure the start to the year has been busy, especially if you’re in northern climates! With a relatively light snowfall, aeration practices have begun or will be in process over the next few weeks. GreenSight headquarters has also been extremely busy! Our sales team has been meeting with existing customers and bringing new ones into the sky! Our software/development team has been busy working on new integrations such as Spectrum Technologies TDR350 moisture meter data and continuing to perfect our industry leading flight time Dreamer drone. Our flight ops team is not only continuing to fly and produce incredible imagery ready for your analysis but they are also producing waivers to get that much closer to fully autonomous missions.

The following imagery set is from a mission at the Wianno Club in Massachusetts. As you can see, Golf Course Superintendent Blaine Doherty and the turf team just completed fairway aeration. The High Res. image below shows a magnificently detailed picture of turf, sand, drain lines, and contour. While this imagery is beneficial, our drone also carries other cameras on-board will help go into heavier detail.


As meticulous as the NDVI imagery can be at identifying turf health, it can also assist in highlighting where the turf had too much, too little, or the perfect amount of sand. From the sky, it also helps point out notifications for turf stress, turf injury, or complete turf cover that may need another blow, sweep, or drag. If a turfgrass plant is completely visible to the camera, the image will bounce back a brilliant green. The level of detail in our NDVI imagery will even highlight drain lines and sweep lines. This will help validate your process or help you consider your efforts for your next fairway application. It will allow for a more calculated and precise measurement saving time and money during the next application!


The third image is from our drone’s thermal camera. This camera may be the most beneficial, especially when the drone is flown a few hours after the topdressing application has been completed. It will give insight into surface temperature when considering irrigation run times. Sand will naturally heat up quite a bit faster than turf, so this may also just mean that there is a heavier concentration of sand in these areas.


Whether you’re brand new to your property or you’ve been managing turf at the same facility for 30 years, perhaps this post may make you think about your next application. What would your topdressed turf look like from the sky?

Thank you to Blaine Doherty and the Wianno Club for allowing us to use their pictures for this release!

As always, feel free to get in touch if you have any questions.
