Applied research at the frontier of spatial computing
Airfree's research division advances the science and engineering of geospatial intelligence — publishing peer-reviewed work, releasing open datasets, and translating discoveries directly into production infrastructure used by governments and enterprises across the Asia-Pacific.
Research areas
Six interconnected disciplines that together define Airfree's research agenda and differentiate our platform capabilities.
Spatial AI
Developing foundation models for geospatial reasoning, integrating large language models with spatial graph structures to enable natural-language querying of complex geographic datasets and automated feature extraction at continental scale.
Digital Twins
Advancing real-time synchronisation architectures for city-scale digital twins, including physics-informed simulation layers, IoT sensor fusion pipelines, and photorealistic rendering of dynamic urban environments.
Earth Observation Analytics
Building automated change-detection and land-cover classification pipelines over multi-spectral and SAR imagery, with particular focus on bushfire recovery, coastal erosion, and agricultural monitoring across the Indo-Pacific region.
Sovereign Cloud Architectures
Designing air-gapped and sovereignty-preserving infrastructure patterns for sensitive geospatial workloads in government and critical-infrastructure contexts, covering encryption-at-rest, data residency enforcement, and federated identity.
LiDAR Processing
Creating next-generation point-cloud compression, semantic segmentation, and real-time streaming algorithms capable of handling billion-point datasets on commodity hardware, with applications in infrastructure inspection and autonomous navigation.
Satellite Image Fusion
Researching super-resolution and data-fusion techniques that combine optical, hyperspectral, and radar imagery from heterogeneous constellations into unified, analysis-ready data cubes aligned to open OGC standards.
Active research projects
Current externally funded programs conducted in partnership with government agencies and leading research universities.

Publicly released datasets
Airfree believes that foundational geospatial data should be a shared resource. We release curated, analysis-ready datasets to accelerate the broader research community.
AusUrban-LiDAR-1B
One billion classified point-cloud returns across six Australian capital cities, collected at 20 pts/m², with building, vegetation, ground, and infrastructure labels.
AgriBench-500k
Labelled field-parcel dataset covering 500,000 agricultural parcels across Queensland and New South Wales, with multi-season NDVI time series and yield ground-truth annotations.

PhD & researcher program
Airfree co-sponsors PhD candidates and hosts research interns through structured programs with our university partners. Candidates work on live research problems with direct access to production-scale data infrastructure, publication support, and a pathway to full-time employment upon graduation.
We currently offer placements in Spatial AI, Digital Twins, and Earth Observation Analytics. Stipends are competitive with ARC scholarships and are supplemented by Airfree top-up funding. Candidates retain full intellectual-property rights over their thesis contributions and are co-authors on any resulting publications.
