Light Detection and Ranging (LiDAR) for Improved Mapping of Wetland Resources and Assessment of Wetland Conservation Practices

چکیده
Relief relative to a local elevation maximum provided a strong indicator of inundation dynamics (i.e., hydroperiod), but was less useful for mapping wetland boundaries. Combining local relief and an Enhanced Topographic Wetness Index produced a map that was well suited for mapping wetland extent and hydroperiod. Wetlands mapped using aerial photographs or LiDAR-derived digital elevation models (DEMs) contained a similar amount of inundated area, but the LiDAR-derived maps contained fewer errors of omission. For this reason, it was concluded that DEM based topographic metrics produced enhanced inundation maps relative to aerial photography derived maps.

متن کاملAgricultural conservation practices and wetland ecosystem services in the wetland-rich Piedmont-Coastal Plain region
In the eastern U.S. Coastal Plain and Piedmont region, diverse inland wetlands (riverine, depressional, wet flats) have been impacted by or converted to agriculture. Farm Bill conservation practices that restore or enhance wetlands can return their ecological functions and services to the agricultural landscape. We review the extent of regional knowledge regarding the effectiveness of these con...
