To analyze the distribution and abundance of RIFA at the study site, 4. To synthesize the information to develop a risk rating system. The landscape also typically contains cleared woodlands, agricultural fields, farm ponds and road corridors. Affine transformation was consistently better than 3.0 meters. Histogram matching was employed to normalize the coloring between images.
Yellow arrows represent optimal flight path for image capture.
Blue X's indicate image principle points. Landscape Classification Landscape elements were classified by outlining, scanning and digitizing patches. Each polygon was assigned a unique identification code according to its corresponding landscape element type. Sampling protocol required that field records of landscape element were compared against the element types assigned by photo interpretation to verify accuracy of the classification. Color was used similarly for vegetation types.
