Checking crop and paddock health from the air: what SkyVector can do for your farm

You know your paddocks. You know which corner floods and which gateway turns to mud by July. What's hard is seeing the whole block at once, on the same day, in enough detail to spot the patterns you miss from the bike.

That's the job we do at SkyVector. We fly three things for Waikato farmers and growers: top-down maps, drone footage and thermal. Here's how each one helps with crop and paddock health, and where the limits are.

1. Top-down maps (RGB orthomosaics)

We fly a grid over the block with a standard colour camera and stitch hundreds of photos into one sharp, top-down map. You can zoom in on any corner and see the paddock as it was on the day we flew.

On farm, a map is good for:

  • Uneven strike or emergence. Gaps in rows, thin patches and failed areas in new crops or regrassing stand out from above.
  • Wet spots and drainage. Ponding, darker soil and lagging growth often line up with low spots or blocked drains.
  • Pugging and stock damage. Gateways, troughs and laneway edges are easy to see and size up after a wet spell.
  • Irrigation coverage. Missed strips, overlaps and dry arcs from pivots or travelling irrigators often show as colour differences.
  • Weed or pest patches. Larger patches that look different from the surrounding crop can be found quickly, so you know where to walk.
  • Layout and planning. Boundaries, tracks, races and paddock shapes in one clear picture. It's a working map for planning, not a legal survey.

The real value is repeat flights. Fly the same block at sowing, mid-season and before harvest, and you've got a simple record of how it's tracking.

2. Drone footage

Sometimes you don't need a map, you need a quick look. After a storm or flood, a short flight gives you footage of lodged maize, flattened cereal, fallen trees, washed-out tracks or slips across the whole property, often in less time than it takes to drive it. That footage is useful for planning the clean-up, briefing contractors, or as a record for your insurer or bank.

3. Thermal

A thermal camera records surface temperature, which makes it useful for anything to do with water:

  • Irrigation faults. Blocked nozzles, leaks and uneven application can show as warmer or cooler strips.
  • Wet ground and seepage. Wet soil usually reads cooler than dry soil, so wet areas can stand out, often most clearly early in the morning.
  • Water stress. Plants short of water can't cool themselves as well, so they may read warmer than their neighbours.

Thermal works best when it's flown at the right time in the right conditions, and it only sees the surface. A warm or cool patch tells you something is different, not exactly why. We'll talk through timing with you before we fly.

What about multispectral and NDVI?

You may have heard of multispectral cameras and NDVI vegetation maps. They use near-infrared light to score plant vigour across a paddock. We don't offer them at the moment, and we won't pretend otherwise. For a lot of everyday problems (wet areas, poor strike, pugging, storm damage, irrigation gaps) a good colour map and thermal will show you what you need.

What a drone doesn't replace

A drone shows you where to look. It doesn't diagnose. Nutrient problems, disease, pests and compaction can look alike from above, so you'll still want to walk the problem areas and talk to your agronomist or farm consultant. Our job is to save you time finding those areas and to give you a clear record.

When it's worth booking a flight

  • The block is too big to walk all of it properly.
  • Something's gone wrong (storm, flood, failed strike) and you need a fast picture.
  • You want a record across the season to compare.
  • An irrigation or drainage problem isn't obvious from the ground.

Book a farm flight with SkyVector

We're based in Hamilton and fly farms and growing blocks across the Waikato. Tell us what you're trying to find out and we'll recommend a map, footage, thermal or a mix, and the best time to fly it. If a flight won't help, we'll tell you straight.

For the details of each option, see crop stress mapping with thermal and colour imagery or farm mapping, which gives you a current aerial map of paddocks, drainage lines and tracks. If you need a measured model of sheds, yards or earthworks, 3D mapping and aerial survey is the better fit. You can also check where we fly in the Waikato.
