Wet meadow and fen mapping of Sequoia and Kings Canyon National Parks (geodatabase)

Description

The Wet Meadows and Fens Geodatabase of Sequoia and Kings Canyon National Parks (SEKI) was produced over a three month period (late February through early May 2013). The resulting products are intended to: (1) Identify and classify all target wetlands (wet meadows and fens) >0.5 hectare in the parks and provide an estimate of the proportion of each feature which is peat accumulating. Over 2300 polygons represent wetlands in three mapping classes: wet meadows, fen-meadow complexes, and fens. (2) Identify locations of fens within park boundaries. More than 600 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. Ancillary data informing mapping decisions included: the SEKI Vegetation map, 7.5-minute USGS topographic maps, the National Wetlands Inventory Wetland Layer, the SEKI Rivers and Streams Layer, and 2012 spatial data depicting known fen locations produced by the SEKI Plant Ecology program. Overall spatial accuracy of the resulting map products is equivalent to 1:24000 National Map Accuracy Standards. Overall classification accuracy was estimated to be 83% (90% CI = 78 – 89%) based on field assessments of 138 polygons. Revised mapping class and peat accumulation attributes based on accuracy assessment are included. 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. 2015.
