No Products in the Cart
Both the MicaSense Altum-PT and the RedEdge-P Dual are research-grade multispectral payloads, but they solve different problems. The Altum-PT adds a calibrated thermal sensor to five spectral bands plus a high-resolution panchromatic band; the RedEdge-P Dual drops thermal entirely and instead doubles the spectral information to ten bands. The right choice comes down to one question: does your work need temperature data, or finer spectral discrimination?
Two sensors, two design philosophies
MicaSense built both of these cameras for serious data collection, and both pan-sharpen their multispectral output using a dedicated high-resolution panchromatic band. Where they diverge is the trade-off at the heart of this comparison: the Altum-PT spends its extra payload budget on a radiometric thermal sensor, while the RedEdge-P Dual spends it on five additional spectral bands. You cannot have both in a single camera, so understanding what each gives up clarifies the decision quickly.
Altum-PT: thermal plus multispectral plus panchromatic
The Altum-PT captures five calibrated multispectral bands centred at Blue (475 nm), Green (560 nm), Red (668 nm), Red Edge (717 nm) and Near-IR (842 nm). Alongside these it runs a 12.4 MP panchromatic band and a FLIR Boson radiometric thermal sensor at 320 x 256 pixels. With a global shutter, it captures at up to two frames per second.
The headline capability is co-aligned thermal and spectral data from a single flight. At 60 m altitude the panchromatic band delivers pan-sharpened multispectral output at roughly 1.25 cm per pixel, while the thermal sensor resolves about 17 cm per pixel. That pairing lets researchers correlate canopy temperature, water stress and evapotranspiration with vegetation indices in one dataset, with no need to fly a separate thermal mission.
- 5 multispectral bands plus panchromatic and radiometric thermal
- Thermal sensor: FLIR Boson, 320 x 256, ~17 cm GSD at 60 m
- Panchromatic: 12.4 MP, ~1.25 cm pan-sharpened GSD at 60 m
- Capture: up to 2 fps, global shutter
- Ships with the DLS 2 downwelling light sensor and a calibrated reflectance panel; NDAA compliant
For applied work that hinges on temperature, the Altum-PT is the obvious tool. Our guide on maximizing crop yields with the Altum-PT walks through how the thermal band surfaces irrigation problems that spectral data alone would miss.
RedEdge-P Dual: ten bands, no thermal
The RedEdge-P Dual is a dual-imager system that combines two synchronised cameras to deliver ten multispectral bands, each at 1.6 MP, sharpened by a 5.1 MP (2464 x 2056) panchromatic sensor. There is no thermal band on this payload.
Those ten bands add Coastal Blue (444 nm), Green (531 nm), Red (650 nm), Red Edge (705 nm) and Near-IR (740 nm) on top of the five-band set the Altum-PT carries. The extra bands sit precisely where many vegetation and water-quality indices are most sensitive, giving the Dual far finer spectral discrimination for classification, species mapping and chlorophyll or pigment analysis. Pan-sharpening lets it reach roughly 2 cm per pixel, and it captures at up to three frames per second across a 50-degree horizontal field of view.
- 10 multispectral bands at 1.6 MP each, no thermal
- Panchromatic: 5.1 MP (2464 x 2056)
- GSD: ~2 cm per pixel pan-sharpened
- Capture: up to 3 fps; 50 deg x 38 deg field of view
When the research question is about subtle spectral differences rather than temperature, that band density is decisive. Our write-up on high-resolution environmental monitoring with the RedEdge-P Dual shows where the additional bands earn their keep.
Side-by-side comparison
| Specification | Altum-PT | RedEdge-P Dual |
|---|---|---|

| Thermal band | Yes (320 x 256 radiometric) | No |
| Panchromatic | 12.4 MP | 5.1 MP |
| Pan-sharpened multispectral GSD | ~1.25 cm at 60 m | ~2 cm |
| Thermal GSD at 60 m | ~17 cm | N/A |
| Capture rate | Up to 2 fps | Up to 3 fps |
Which sensor fits which research
Choose the Altum-PT when temperature is part of your measurement: crop water stress and irrigation scheduling, evapotranspiration modelling, plant phenotyping that tracks canopy temperature, building-envelope or solar inspection alongside vegetation indices, and wildlife or thermal-anomaly survey work. The thermal band is the differentiator, and the high-resolution panchromatic sharpening keeps the spectral output competitive.
Choose the RedEdge-P Dual when spectral detail drives your analysis: detailed land-cover and species classification, invasive-species detection, water-quality and chlorophyll mapping, soil and mineral studies, and any machine-learning pipeline that benefits from richer input features. The five extra bands give you discrimination that no amount of thermal data can replace.
Both sensors integrate cleanly with DJI Enterprise airframes and other platforms; see our guide on integrating MicaSense sensors with DJI Enterprise drones, and review processing multispectral drone data to confirm your software stack supports the band set you intend to collect. For the wider lineup and the broader context, our precision agriculture and forestry pillar guide and the full MicaSense collection are good starting points. If you are weighing the two for a specific program, our team can help you scope the right payload and platform before you commit.
