Geospatial data for the Vegetation Mapping Inventory Project of Wilsons Creek National Battlefield
공공데이터포털
The files linked to this reference are the geospatial data created as part of the completion of the baseline vegetation inventory project for the NPS park unit. Current format is ArcGIS file geodatabase but older formats may exist as shapefiles. Classification was based on 50 quantitative field plots, which were placed across WICR in a stratified random manner based on qualitative field observation points, consideration of biophysical setting, and viewing of air photos. Mapping was based on a combination of image object generation and heads-up digitization of air photos on-screen. Accuracy assessment points obtained during 2012 verified that the map is 81.3% accurate across all classes. GIS Database 2011 - 2012: Wilson’s Creek National Battlefield = 1,975 acres (799 hectares) Base Imagery used for mapping (acquired by MoRAP): 2007-2009, Greene County, MO, leaf-off, true color, 2 ft 2009, Greene County, MO, leaf-on, Color Infrared, 1 m 2009, Greene County, MO, leaf-on, true color, 1 m Additional Imagery acquired and viewed by MoRAP: 1941 Panchromatic Aerial Photo 1936 Panchromatic Aerial Photo Minimum Mapping Unit = 0.5 hectares (ha) Total Size = 379 Polygons Average Polygon Size = 5.21 acres (2.1 ha) Overall Thematic Accuracy = 81.3% Project Completion Date: 11/2012

Imagery data for the Vegetation Mapping Inventory Project of Wilson's Creek National Battlefield

This reference contains the imagery data used in the completion of the baseline vegetation inventory project for the NPS park unit. Orthophotos, raw imagery, and scanned aerial photos are common files held here. The mapping component was produced by identifying land cover in a three-step process: (1) image objects were generated at 1 m resolution using e-Cognition applied to stacked leaf-on and leaf-off air photos, (2) image objects were coded with land cover classes on-screen, and (3) image objects were cut and corrected via heads-up digitizing at a display scale of 1:1,500 against a back-drop of air photos. Imagery was the most recent available from the National Agriculture Imagery Program, This included 2003 to 2007 true color and color infrared imagery. Base Imagery used for mapping (acquired by MoRAP): 2007-2009, Greene County, MO, leaf-off, true color, 2 ft 2009, Greene County, MO, leaf-on, Color Infrared, 1 m 2009, Greene County, MO, leaf-on, true color, 1 m Additional Imagery acquired and viewed by MoRAP: 1941 Panchromatic Aerial Photo 1936 Panchromatic Aerial Photo
