Aerial Photography Project


The following picture is one of several dozen that resulted from a a pilot study of using a normal digital camera strapped to the side of a 4-seater Cessna 182, which Andrew is now learning to fly. The picture is actually made up from two overlapping shots (highlighted), and forms part of a broader mosaic (see second picture).


The photo mosaic covers an area of 2 x 5 kilometres, and was recorded during a 40 minute flight. The photos have been overlaid on a satellite image (of an area just north of the city of Salta). The red line shows the flight path, whilst the darker square are the photos. The flight path is somewhat erratic, as we were experimenting in flying a previously programmed route, plotted on a GPS.



With the support of SAMS, ASOCIANA will now use the experience gained from this pilot study to conduct an aerial survey of forests around indigenous communities near Tartagal. The idea is that the photos will give communities better access to up-to-date and detailed information on what is happening to their natural environment (in terms of advancing deforestion, lumber extraction etc...). This information in turn will enable communities to document any threats that they then will denounce to local and provincial authorities.
