Wet meadow and fen mapping of Yosemite National Park (geodatabase)

Description

The Wet Meadows and Fens geodatabase of Yosemite National Park (YOSE) was produced over a three month period (December 2013 through February 2014). The resulting products are intended to: (1) Identify and classify all target wetlands (wet meadows and fens) >0.5 hectare in the park and provide an estimate of the proportion of each feature which is peat accumulating. Over 1600 polygons represent wetlands in three mapping classes: wet meadows, fen-meadow complexes, and fens. (2) Identify locations of fens within the park boundary. More than 500 fen points identify locations where fens are known or presumed to occur. Mapped polygons are based on photo interpretation of Natural Color and Color Infrared NAIP aerial photography from 2005, 2009, 2010, and 2012 as well as Google Earth and the ESRI World Imagery Basemap. Ancillary data informing mapping decisions included the YOSE Vegetation map, the National Wetlands Inventory Wetland Layer, the YOSE Rivers and Streams Layer, the Yosemite Contiguous Meadow Survey data, and YOSE Meadow Gridpoints. Overall spatial accuracy of the resulting map products is equivalent to 1:24000 National Map Accuracy Standards. These geospatial data are provided in Esri File Geodatabase format containing: (1) a polygon feature class depicting wet meadow and fen delineations; and (2) a point feature class indicating the locations of fens within the park boundary. Detailed metadata are provided in XML format and basic metadata are provided in PDF format. Users of these data should refer to: Pyrooz NN and Others. 2020.
