topo: Land-Surface Topography

Description

Land-surface topography and shaded relief in the vicinity of Idaho National Laboratory, eastern Idaho.

Usage

topo

Format

A RasterStack of the raster package with 2 layers. Grid cells in the "elevation" layer represent land-surface elevations in meters above the North American Vertical Datum of 1988 (NAVD 88). Grid cells in the "hillshade" layer represent shaded relief calculated from the slope and aspect of land-surface elevations. The spatial grid is composed of 900 rows and 900 columns, and has cell sizes that are constant at 100 meters by 100 meters. See projection dataset for coordinate reference system information.
