In USGS-R/wrv: Wood River Valley Groundwater-Flow Model

Description

Hill shading of the Wood River Valley and surrounding area.

Format

An object of RasterLayer class. Each cell on the surface grid represents the hill shade. Geographic coordinates are in units of meters, in conformance with the North American Datum of 1983 (NAD 83), and placed in the Idaho Transverse Mercator projection (IDTM). The spatial grid is composed of 3,108 rows and 2,360 columns, and has cell sizes that are constant at 20 meters by 20 meters.

Source

Calculated from the slope and aspect of the land.surface dataset using the terrain and hillShade functions; see the appendix C. Package Dataset Creation for the R code used in this calculation.

Examples

raster::image(hill.shading, length(hill.shading), col = grey(0:255 / 255), asp = 1,
              axes = FALSE, xlab = "", ylab = "")
