Figure 2. Integration of the TM and DEM data in the 1999 flood mapping study covering the four Greenville quadrangles.
Final flood map derived by combining the TM and DEM data through a logical "OR" for flooded areas. The flooded areas are shown in red and water (regular river channels, ponds, etc.) in blue. The black/white background is a TM band 7 image from September 30, 1999, and represents non-flooded areas.
