The A3 ground processing system was designed to take advantage of the unique characteristics of the A3 camera. Handling the entire scope of processing, from raw image download to generation of mapping products and QA reports, the A3 ground processing system features:

  • Full automation
  • Purely photogrammetric processing
  • Scalable parallel computing
  • Compliance with industry standards and formats
  • Intuitive web based user interface
  • Based on commercial-off- the-shelf (COTS) hardware
  • Extensive QA capabilities

Post-flight processing workflow includes:

  1. Download
  2. Pre-processing and flight debrief
  3. Aerial triangulation
  4. Bundle adjustment QA and geo-referencing GCP inputs (optional)
  5. Mapping Super Large Frame (SLF) export (optional)
  6. DEM/DSM Generation
  7. Orthophoto generation and QA

The A3 system is scalable and can be deployed in various configurations. Typical configuration is based on:

  • 4 Xeon based servers
  • One FC storage
  • Microsoft windows operating system

A typical hardware configuration would be capable of processing 1000 km2, in 0.14 m GSD within less than two days, and would provide block adjustment, Orthophoto, Super Large frames for stereo matching and solved oblique images.
