Drone mapping & precision agriculture

Precision Agriculture

Q: Our farm has poor connectivity. Can you help?

Yes. Rural and remote fields often lack reliable links to move imagery and telemetry, so we design fixed-wireless coverage through our WISP practice, then build the data pipelines and dashboards that turn raw flights into decisions. See our WISP and solutions engineering services for the connectivity and software layers.

We fly your fields, turn multispectral imagery into decisions, and act on them, aerial survey to centimeter accuracy, NDVI and NDRE health maps, variable-rate prescriptions, and spray drones that put product only where the data says it belongs.

Why fly the field

See the field the crop actually feels.

A drone at 120 m sees variability the ground crew never will. We capture imagery at 70-80% overlap and process it into an orthomosaic, a digital surface model, and a point cloud, then layer multispectral bands to reveal stress before it costs yield. Red-edge (~717nm) and near-infrared (~840nm) drive vegetation indices like NDVI and NDRE, mapping vigor plant by plant. RTK and PPK positioning ties every pixel to ground truth, so the prescription that comes out is precise enough to spray or spread on.

✓Centimeter accuracy. RTK/PPK delivers ~2-3 cm horizontal, ground sample distance down to ~5-8 mm/px, fewer ground control points needed.
✓Health you can act on. NDVI and NDRE turn reflectance into zones for scouting, nitrogen, and variable-rate application.
✓Map and act together. Prescriptions flow straight to spray drones and variable-rate gear, not just a PDF report.

Capabilities

From flight line to prescription.

An end-to-end precision-ag stack, capture, process, decide, and act, with the connectivity and software to hold it together.

Aerial survey & photogrammetry

Structured flight lines at 70-80% overlap produce an orthomosaic, digital surface model, and dense point cloud. RTK/PPK ties every frame to real-world coordinates for ~2-3 cm accuracy and GSD to ~5-8 mm/px, enough for plant counts, gap analysis, and volumetrics.

Multispectral imaging

Red-edge (~717nm) and NIR (~840nm) bands drive NDVI = (NIR-Red)/(NIR+Red) and NDRE for crop-health zoning.

Variable-rate prescriptions

Health maps become VRA prescription files for seed, nutrient, and chemical, rate matched to each zone.

Spray & application drones

DJI Agras T50-class platforms execute the prescription at roughly 40-52 acres per hour and 400-450 acres per day, applying product only where the map calls for it, less drift, less waste, tighter records.

Rural connectivity

How it works

Plan, fly, process, act.

01 / PLAN

Mission design

We set altitude, overlap, and band selection to your crop and goal, and place RTK/PPK references for accuracy.

02 / FLY

Capture

Mapping drones cover ~200 ha per flight at 120 m; imagery is logged with position for tight georeferencing.

03 / PROCESS

Turn pixels into maps

Photogrammetry builds orthomosaic, DSM, and point cloud; multispectral bands become NDVI, NDRE, and zones.

04 / ACT

Prescribe & apply

Zones become VRA prescriptions, then spray drones and variable-rate gear execute them, cutting inputs ~30-50%.

Questions

Precision agriculture, answered.

What is NDVI and why does it matter?

NDVI (Normalized Difference Vegetation Index) is calculated as (NIR – Red) / (NIR + Red) from a multispectral camera. Healthy plants reflect strongly in near-infrared, so a higher NDVI means denser, more vigorous canopy. It highlights stress, gaps, and variability across a field long before the eye can see it. NDRE, which uses the red-edge band around 717nm, penetrates dense canopy and is better for mid-to-late-season nitrogen status.

How accurate is the mapping?

With RTK or PPK positioning we deliver roughly 2-3 cm horizontal accuracy and can push ground sample distance down to about 5-8 mm per pixel at low altitude. That is precise enough for plant counts, gap analysis, and volumetric measurement, and it reduces or eliminates the need for dense ground control points.

Do you spray, or just map?

Both, and they work together. Mapping drones capture multispectral imagery that becomes NDVI, NDRE, and variable-rate prescription maps. Spray drones such as the DJI Agras T50 then execute those prescriptions, covering roughly 40-52 acres per hour and 400-450 acres per day, applying product only where the data says it is needed.

How many acres can you cover in a day?

For mapping, a Mavic 3 Multispectral covers about 200 hectares per flight at 120 m altitude, so several thousand acres per day is realistic with battery swaps. For application, a T50-class spray drone runs roughly 400-450 acres per day depending on rate, refill logistics, and field layout.

Our farm has poor connectivity. Can you help?

Yes. Rural and remote fields often lack a reliable link to move imagery and telemetry, so we design fixed-wireless coverage through our WISP practice, then build the data pipelines and dashboards that turn raw flights into decisions through our solutions engineering team.
