Unfortunately, FCT lacked the expertise and resources to incorporate the photos into its existing Geographic Information System (GIS), so the prints were sporadically used in qualitative visual analysis on an ad hoc, site-specific basis only. Not surprisingly, the cumbersome nature of the nearly 100 prints, as well as the varying scale, often poor print quality, and systematic distortion inherent in aerial photography (particularly from the extreme terrain differences contained in each photo), made for their difficult, imprecise, and generally ineffective use. Although manual, visual analysis of the prints revealed obvious land cover changes, they provided no possibility for accurate areal calculations or location in geographic space (Figure 3).
