topoProfile: Elevation profiles of topographic paths

In topoDistance: Calculating Topographic Paths and Distances

Elevation profiles of topographic paths

Description

Plots topographic cross sections (elevation profiles) of topographic paths

Usage

topoProfile(
  DEM,
  topoPaths,
  pts = 100,
  type = "base",
  singlePlot = FALSE,
  rows = NULL,
  cols = NULL,
  limits = NULL,
  legendx = "bottomright"
)

Arguments

DEM	A RasterLayer for digital elevation model (DEM) data.
topoPaths	A SpatialLines object containing the topographic paths to be plotted.
pts	numeric (default = 100). The number of elevation points to plot along each path.
type	character (default = "base"). Type of plotting: "base" or "plotly".
singlePlot	logical (default = FALSE). If TRUE, profiles will be drawn on a single plot.
rows	numeric (optional). Number of rows for plot layout (if singlePlot = FALSE)
cols	numeric (optional). Number of columns for plot layout (if singlePlot = FALSE)
limits	numeric vector (optional). A vector with the lower and upper limits for the y-axis (elevation).
legendx	character (default = "bottomright"). Position for the legend.

Details

For the type argument, choosing "base" will use base R plotting, and choosing "plotly" will draw an interactive plot with the plotly package.

If rows, cols, or limits are not specified, the most even arrangement will be detected and used.

Value

Plot of elevation profiles

Examples

xy <- matrix(ncol = 2, byrow = TRUE,
   c(-119.5566, 37.7247,
     -119.4718, 37.7608))
YosPaths <- topoDist(Yosemite$DEM, xy, paths = TRUE)
topoProfile(Yosemite$DEM, topoPaths = YosPaths)
