Technological Advances in Wetland Mapping

When:

March 9, 2017: 8:00AM to 9:30AM

Where:

The Plaza Diner, 27 New Paltz Plaza, New Paltz, NY 12561 map

Wetland Inventory (NWI) maps are based almost exclusively on photo interpretation at a scale seldom useful at a local level and often spatially offset from updated framework GIS data layers. Laurie’s project team has used recently-updated high resolution LiDAR and other data to improve NWI mapping. Using these new techniques, mapped wetland acreages have increased 75-140% in pilot areas. After evaluating the drainages associated with these wetlands, the extent of wetlands estimated to be “unconnected” to stream networks was also reduced by almost 80%.

At this speaker event, Featured Speaker Laurie Machung, Wetlands Program Supervisor, NYCDEP Bureau of Water Supply, Ecological Research & Assessment Current National will provide an overview of her work and consider the implications of improved mapping and connectivity assessment for wetland and stream corridor management.
