    dct:description """Four polygon vector data sets and one related table describe land-cover in Red Rock Canyon 
National Conservation Area (RRC_NCA_p) and Coyote Springs (CS_ACEC_p), Piute-Eldorado 
Valley (PEV_ACEC_p), and Mormon Mesa (MM_ACEC_p) Areas of Critical Environmental 
Concern, Clark County, Nevada. One polygon vector data set per Area is attributed with land-
cover at the vegetation stand level (abbreviated with a stand code) and the corresponding 
alliance level of the National Vegetation Classification Standard (NVC; Federal Geographic 
Data Committee, 2008). The table (tbl_NVC) is related to each of the four polygon data sets 
and contains the NVC classification from the group to class level. DigitalGlobe's QuickBird 
multispectral satellite imagery was classified with field vegetation data (Charlet and others, 
2014) collected at the stand level using Visual Learning Systems' Feature Analyst feature 
extraction software. Non-vegetation data layers, such as roads and disturbed areas, were 
manually delineated from the QuickBird imagery. The process steps have been generalized 
to apply to all study areas. Details about processing, such as vegetation samples used for 
training input and major changes made during photo interpretation are detailed in the larger 
work. For simplicity, the process dates are listed as the final publication date. Red Rock 
Canyon National Conservation Area was processed during 2008, Coyote Springs Area of 
Critical Environmental Concern during 2011, Piute-Eldorado Valley Area of Critical 
Environmental Concern during 2012, and Mormon Mesa Area of Critical Environmental 
Concern during 2013.
