High resolution shrub cover of JER and CDRRC (2011)

General Information

Data Package:
Local Identifier:	knb-lter-jrn.100.3
Title:	High resolution shrub cover of JER and CDRRC (2011)
Alternate Identifier:	DOI PLACE HOLDER
Abstract:	This data package contains two raster shrub cover maps of the Jornada Experimental Range and Chihuahuan Desert Rangeland Research Center (CDRRC) created using 1m resolution National Agriculture Imagery Program (NAIP) aerial photo acquired in 2011. A one-meter resolution raster file lists cover as non-shrub, shrub, or no data available. A hectare resolution raster file contains fractional shrub cover values (0-1) calculed from the 1 meter raster. NOTE: There is currently a hole in the coverage of the hectare raster (no-data values) in the "scarplet" region in the southeastern portion of the Jornada Basin. The creators of the dataset plan to fill this missing area of coverage in a future update to the data package once suitable imagery of the area is acquired.

Methods and protocols used in the collection of this data package

Description:

We used National Agriculture Imagery Program (NAIP) aerial imagery acquired on 21 May 2011 to generate the shrub cover map. NAIP images have a 1m spatial resolution and four spectral bands (red, green, blue, and near-infrared). An unsupervised approach (Iterative Self-Organizing Data Analysis Technique) was used for image classification. Texture features were used in addition to the NAIP spectral bands. Thirty classes were initially produced by the unsupervised classification; these were then manually assigned as shrub or non-shrub. Necessary corrections of the classification (through combining and/or splitting of the original thirty classes) were done manually while referencing co-located Google Earth imagery.
