Normalized Difference Vegetation Index Corresponding to Vegetated Areas in the Combined Groundwater Discharge Area and Area of Critical Environmental Concern, Stump Spring, NV

This dataset, created in support of USGS Scientific Investigations Report 2020-5075, Estimates of Groundwater Discharge by Evapotranspiration, Stump Spring and Hiko Springs, Clark County, Nevada, 2016-18, represents a Normalized Difference Vegetation Index calculated for vegetated areas in the Stump Spring groundwater discharge area (GDA) and Area of Critical Environmental Concern (ACEC). Vegetated areas within the GDA are composed of phreatophytic shrubs interspersed with xeric vegetation and bare soil. The GDA was delineated by visual interpretation of 1-meter National Agriculture Imagery Program (NAIP) aerial imagery acquired in May of 2015. The NDVI was calculated from a June 2017 WorldView 2 image resampled to 1-meter cell size and masked to remove bare ground areas identified from a supervised classification based on the same 2015 NAIP image used to define the GDA.
