Aerial imagery

Aerial imagery is remarkably easy to come by these days and can be extremely useful in identifying interesting bushwalking features, potential routes and vegetation thickness. It’s easy to spot urban areas, constructed buildings and tracks and possible to determine elevation via shadows.


Aerial imagery means any images taken from an elevated position, including photography from helicopters, fixed wing aircraft or drones, right through to air balloons, parachutes and satellites.


A few free sources include:
- SIX maps NSW
- Google Maps
- Google Earth


Google Maps also gets its high-resolution images of cities from aircraft flying at 240 to 460 m, and the rest from satellites. LANDSAT satellites have been pivotal in providing accurate environmental data about the earth’s surface and in 2016 google earth has released worldwide images sourced from Landsat 8. Most of the satellite images are no more than three years old, meaning that the user can be confident that the information is reasonably accurate and current.
