500-m Buffers around Valley Floors

A GIS raster layer consisting of concentric buffers 500 m wide around the level valley floors is provided in Idrisi (BUFFER-IDRISI.ZIP) and GeoTIFF (BUFFER-GEOTIFF.ZIP) formats. Cell values are as follows:

• 0=territory outside the survey area
• 1=level valley floors (or rivers where there was no adjacent level valley floor)
• 2=buffer 0.0-0.5 km from valley floor edge
• 3=buffer 0.5-1.0 km from valley floor edge
• 4=buffer 1.0-1.5 km from valley floor edge
• 5=buffer 1.5-2.0 km from valley floor edge
• 6=buffer 2.0-2.5 km from valley floor edge
• 7=buffer 2.5-3.0 km from valley floor edge
• 8=buffer 3.0-3.5 km from valley floor edge
• 9=buffer 3.5-4.0 km from valley floor edge
• 10=buffer 4.0-4.5 km from valley floor edge
• 11=buffer 4.5-5.0 km from valley floor edge
