Airfree
Earth Observation

Satellite intelligence at planetary scale

From a single field to a nation, our earth observation pipelines transform raw satellite data into decision-ready spatial intelligence — continuously, automatically, at any scale.

Access EO analytics

Sensor types

Every wavelength, every weather condition

Airfree ingests data from all major satellite sensor modalities — combining their strengths to fill each other's blind spots.

Optical Multispectral

RGB, NIR, SWIR bands from Sentinel-2, Landsat, and PlanetScope. 10 m resolution, 5-day global revisit.

Synthetic Aperture Radar

All-weather, day-and-night imaging from Sentinel-1. Penetrates cloud cover — essential for tropical and polar monitoring.

Hyperspectral

100+ narrow spectral bands for fine material classification: geology, crop species, mineral mapping, water quality.

Thermal Infrared

Surface temperature mapping for urban heat islands, industrial emission monitoring, and active fire detection.

GNSS Reflectometry

Soil moisture retrieval, flood extent estimation, and sea-ice mapping using reflected GPS signals from spaceborne receivers.

Processing pipeline

From raw data to actionable insight

01

Acquisition

Satellite tasking requests and archive search across commercial and open-access constellation APIs.

02

Atmospheric Correction

Top-of-atmosphere to surface reflectance conversion using Sen2Cor, LaSRC, and custom aerosol models.

03

Orthorectification

Geometric correction to terrain using high-resolution DEMs, sub-pixel registration accuracy.

04

Analysis-Ready Data

Standardised Cloud-Optimised GeoTIFF and STAC catalogue output — ready for immediate analysis.

05

AI Classification

Automated feature extraction using Airfree spatial AI models: land cover, change detection, object identification.

06

Insight Delivery

Results delivered via REST API, interactive dashboard, automated alert, or bulk export.

Spectral indices

Standard products, ready to use

Pre-computed spectral indices are available for every scene in the archive — no custom processing required.

NDVI
Normalised Difference Vegetation Index
Crop health, biomass, forest cover
NDWI
Normalised Difference Water Index
Surface water extent, flood mapping
NBR
Normalised Burn Ratio
Fire severity, post-fire rehabilitation
SAR Coherence
Interferometric Coherence
Ground stability, subsidence detection
BSI
Bare Soil Index
Agricultural bare soil, erosion risk
NDBI
Normalised Difference Built-up Index
Urban expansion, impervious surface

Archive depth

Multi-decade time series — change detection from 1984 to present

The full Landsat and Sentinel archives, pre-processed to analysis-ready data, mean you can query land cover change across four decades for any point on Earth.

40+
years of archive
