    • Normalized Difference Vegetation Index for Vegetated Areas of the Groundwater Discharge Area, Hiko Springs, NV

    Metadata Updated: July 6, 2024

    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 Hiko Springs groundwater discharge area. 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. Areas of channel scour within the GDA resulting from a flood event in September 2015 were delineated from a 2016 1.84-meter resolution Worldview 2 image. The NDVI was calculated from the same WorldView 2 with bare ground areas masked and calculated as "no data".
