Low level Flights-
Riparian areas are differentially valuable for wildlife, recreation and water quality. We have helped devise a technique that we are now perfecting. Using low level aerial photography, 700 photos were taken along 47 miles of stream in one day. The following images show two photographs of the same riparian area. The top image was taken in July 2003 while the bottom image way taken in September of 2004. Along site each photograph is a spectral rendition of the photograph that can be quantified.
We have developed a quick way of quantifying these images by converting and correlating the photograph’s vegetation and land conditions into spectral attributes. Using this technique we were able to measure the change in the cover of willows, shadow, shadow on water, water, rocks and riparian vegetation.
This technique is just one of many that we have developed for the purpose of providing managers with timely, low cost and high sample size rangeland data. So these managers can with make decisions, improving there management and plans and provide information to their interested publics for outreach and/or markets.
