Appendix H

D8 Comparison at 10-m Resolution of USGS and LiDAR Generated Data

Appendix Figure H1. The D8 flow algorithm applied to the USGS and LiDAR Generated 10-m DEM. Illustrates that stream channels with a catchment size of about 12-ha and greater somewhat converge between the two DEM’s with regards to D8. When catchments are less than 12-ha, differences in stream channel location are shown.

Appendix Figure H2. USGS and LiDAR Generated 10-m, D8 Comparison. Streams identified as identical if 30-m apart.

Appendix Figure H3. USGS and LiDAR Generated 10-m, D8 Comparison. Streams identified as identical if 90-ft apart.
