Platform Architecture
The technology stack powering spatial intelligence at scale
Five integrated technology pillars — geospatial, AI, earth observation, cloud, and sovereign security — delivered as a unified platform for governments and enterprises.
Five Pillars
Integrated by design. Deployable independently.
Each pillar is a production-grade product discipline. Together they form the Airfree Platform — the only end-to-end spatial intelligence stack built for national-scale operations.
Geospatial Intelligence
Enterprise GIS, cadastral systems, and spatial analytics built on open standards. From sub-metre survey accuracy to continental-scale land administration.
Learn moreArtificial Intelligence
Spatial foundation models, change-detection pipelines, and AI-assisted feature extraction purpose-built for geospatial workloads.
Learn moreEarth Observation
Multi-source EO ingestion — optical, SAR, LiDAR, hyperspectral — with automated pre-processing, analysis-ready data cubes, and STAC cataloguing.
Learn moreCloud Platform
Kubernetes-native, multi-region geospatial cloud infrastructure with auto-scaling tile services, streaming pipelines, and bare-metal options for data-sovereign deployments.
Learn moreSovereign Security
Zero-trust architecture, cryptographic data lineage, and nationally-compliant key management — engineered for government and defence-grade classification requirements.

From raw data to actionable insight
The Airfree Platform processes data across five ordered layers. Every layer exposes standard interfaces, enabling customers to connect at any depth — from raw data ingestion to finished visualisation.
Data Ingestion
Satellite feeds, sensor networks, survey instruments, third-party APIs, and batch uploads. Supports real-time streaming (Kafka) and scheduled ETL at petabyte scale.
Processing
Distributed raster and vector compute on Dask and Spark. Automated QA, orthorectification, tiling, and point-cloud classification run in parallel across GPU clusters.
Analysis
AI inference pipelines, spatial statistics, change detection, and hydrological modelling. All analytical outputs are versioned and cryptographically signed.
Delivery
OGC-compliant services (WMS, WFS, WCS, WMTS), REST and GraphQL APIs, webhook event streams, and secure file download — all behind role-based access control.
Visualisation
Web clients (Airfree Maps), 3D digital twin environments powered by Cesium, QGIS plug-ins, and embeddable SDK components for third-party portals.
Platform Performance
Numbers that define enterprise-grade
The engineering targets and design specifications the platform is built to — the performance envelope behind every government and enterprise deployment.
Satellite imagery the multi-source EO pipeline is engineered to process per hour
Achievable relative accuracy in cadastral surveys with GNSS-assisted adjustment
Target median tile-service response time under sustained load
Uptime SLA across Airfree Cloud production regions
Cadastral parcel datasets the Airfree LandX platform is built to manage
Standards & Interoperability
Built on open standards. Engineered for enterprise.
Every Airfree service is designed for standards compliance from day one. Customers integrate using formats they already know, with no vendor lock-in at the data layer.
Airfree actively participates in OGC working groups and contributes open-source tooling that advances interoperability across the geospatial industry.

Open Source
We build in the open where it matters
Airfree contributes foundational tooling back to the geospatial open-source ecosystem. These projects are used in production by organisations outside Airfree and are maintained by our engineering teams.
High-performance STAC API server with PostGIS backend and RBAC extensions.
CLI and library for converting arbitrary rasters to Cloud-Optimised GeoTIFFs at scale.
Utilities for converting and partitioning vector datasets to GeoParquet format.
Kubernetes operator for declarative management of distributed tile-cache clusters.
QGIS plug-in exposing Airfree GIS services, authentication, and data catalogs.
Open framework for cryptographic provenance tracking of geospatial datasets.
Integration Ecosystem
Connect to everything. Own your data.
Airfree exposes every capability through well-documented APIs. Whether you are building a custom portal, automating a field workflow, or integrating with enterprise GIS infrastructure, the tools are there.
REST & GraphQL APIs
Fully versioned, OpenAPI 3.1-documented REST endpoints and a unified GraphQL schema covering all platform resources. OAuth 2.0 and API-key authentication.
Webhooks & Streams
Real-time event delivery via signed webhooks and Kafka-compatible streams. Subscribe to dataset updates, processing completions, sensor alerts, and permission changes.
SDKs & Plug-ins
TypeScript, Python, and Java SDKs. Native QGIS and ArcGIS Pro plug-ins. Embeddable web map components for third-party portals — all open-licensed.
