Multispectral Drones for Precision Agriculture, Forestry & Environmental Research

Why Multispectral Imaging Matters for Agriculture and Forestry

A standard RGB camera records only what the human eye sees. Multispectral sensors instead capture discrete, calibrated bands across the visible and near-infrared spectrum, including the red edge transition that is one of the earliest indicators of plant stress. Because chlorophyll strongly reflects near-infrared light and absorbs red light, indices such as NDVI (Normalized Difference Vegetation Index) and NDRE expose differences in vigour, nitrogen status and biomass that an RGB image simply cannot show.

For professionals, that translates into actionable outcomes: variable-rate fertilizer prescriptions, early detection of disease and pest pressure, irrigation and drainage planning, tree species classification, canopy mortality mapping, and water-quality assessment across wetlands and shorelines. The full MicaSense sensor lineup is built around radiometric calibration, so the reflectance values you measure this week are comparable to the values you measure next season.

What Multispectral Data Reveals

• Plant health and vigour through NDVI, NDRE and other vegetation indices derived from red, red edge and near-infrared bands.
• Nitrogen and nutrient status, supporting variable-rate application and reduced input waste.
• Water and moisture analysis, including stressed zones, drainage issues and surface water classification.
• Species identification and forest inventory, separating conifer from deciduous canopy and flagging mortality or disease.

The MicaSense Lineup at a Glance

Every sensor below ships with the DLS 2 downwelling light sensor with embedded GPS and a Calibrated Reflectance Panel, the two components that make MicaSense data scientifically defensible across changing light conditions. The right choice depends on whether you need thermal data, maximum spatial resolution, or the widest possible spectral coverage.

Altum-PT: Multispectral, Thermal and Panchromatic in One Payload

The MicaSense Altum-PT is the most capable single sensor in the family, combining five calibrated multispectral bands (blue 475 nm, green 560 nm, red 668 nm, red edge 717 nm, near-IR 842 nm) with a 12.4 MP panchromatic sensor and a 320 x 256 FLIR Boson radiometric thermal camera. Pan-sharpening delivers ground resolution as fine as 1.25 cm per pixel when flying at 60 m, while the thermal sensor produces roughly 17 cm thermal GSD at the same altitude. With a global shutter and capture rates up to two images per second, it suits operators who need plant health, canopy temperature and detailed mapping in a single flight. Our guide on maximizing crop yields with the Altum-PT walks through field workflows in detail.

RedEdge-P: High-Resolution Five-Band Mapping

The MicaSense RedEdge-P pairs five multispectral bands at 1.6 MP each with a 5.1 MP panchromatic band and a global shutter, producing pan-sharpened ground resolution of about 2 cm per pixel at 60 m. Capturing up to three frames per second, it is the workhorse for large-area crop scouting and forestry inventory where spatial detail and efficient coverage matter more than thermal data. It is a core option within the agriculture drones category for growers and consultants standardizing on calibrated reflectance.

RedEdge-P Dual: Ten-Band Spectral Coverage

The MicaSense RedEdge-P Dual combines two RedEdge-P imagers into a single 10-band system, layering the standard band set with additional narrow bands such as coastal blue, additional red edge and refined visible bands. That expanded coverage supports more sophisticated indices and tighter discrimination between species, crop varieties and water features, which is why it is favoured for environmental research and academic programs. See high-resolution environmental monitoring with the RedEdge-P Dual for applied examples, and Altum-PT vs. RedEdge-P Dual if you are weighing thermal capability against extra spectral bands.

RedEdge-P Triple: Maximum Spectral Resolution

The RedEdge-P Triple extends the concept further with a three-camera configuration that captures up to 15 multispectral bands, delivering the broadest spectral coverage in the MicaSense range. It is aimed at demanding research applications where the finest possible spectral discrimination is required across vegetation, soil and water targets.

Integration with DJI Enterprise Drones

MicaSense sensors are designed to fly on enterprise multirotor platforms, with integration kits and gimbal mounts that pair the payload with DJI enterprise airframes alongside the DLS 2 light sensor for in-flight irradiance correction. Proper mounting, power and triggering are essential to clean datasets, so we recommend reviewing our guide on integrating MicaSense sensors with DJI enterprise drones before your first deployment.

From Capture to Insight: The Data Pipeline

Calibrated raw imagery is only the first step. A typical pipeline begins with a calibration panel image before and after flight, followed by photogrammetric processing into radiometrically corrected reflectance orthomosaics. From there, analysts generate NDVI, NDRE and thermal layers, then translate those into prescriptions, inventory maps or monitoring reports. Our overview of processing multispectral drone data for actionable insights covers the software options and best practices, and the case study on improving fertilizer efficiency in Canadian farming shows how the workflow pays off in the field.

Choosing the Right Sensor

If you need temperature data and high-resolution mapping together, the Altum-PT is the most complete tool. If your priority is spatial detail across large agricultural or forested areas, the RedEdge-P offers the best balance of resolution and efficiency. For research that depends on fine spectral discrimination, the RedEdge-P Dual and Triple provide expanded band sets.
