11. Cover the site with overlapping images and use software to stitch them together into a single photomap and georegister it to Google Earth imagery of the property
12. Tag the individual photos with GPS data to georeference them for viewing on Google Maps, Google Earth, or others
13. Develop methods to use the photomaps for work planning, tracking progress and communicating results to encourage participation in the initiative. Document the approach and techniques

15. GPS unit with tracking and logging capability (optional, where needed)
17. Balloon or kite with enough lift capability to carry the camera, GPS unit, housing and sufficient tether line to reach height of interest for the photographs
18. A safe area to test the system and process and a safe approach to use the process in the field
