bathyMap: Plot Bathymetry Map

In rLakeHabitat: Interpolate Bathymetry and Quantify Physical Aquatic Habitat

Plot Bathymetry Map

Description

Generate a bathymetry map from a provided DEM raster with optional contours and depth labels.

Usage

bathyMap(
  DEM,
  contours = TRUE,
  start = NULL,
  end = NULL,
  by = 5,
  breaks = NULL,
  units = "ft",
  labels = TRUE,
  textSize = 1.5,
  plotTitle = NULL
)

Arguments

DEM	SpatRaster object of a given waterbody, rasters can be transformed to SpatRaster via the rast() function in 'terra'
contours	logical indicating whether contours should included (TRUE) or not (FALSE), default = TRUE
start	numeric value describing what value contours should start at, default = 0
end	numeric value describing what value contours should end at, default = max depth
by	numeric value describing contour intervals, default = 5
breaks	optional numeric vector describing specific contours to include if contours = T, default = NULL
units	character describing units of depth measurement, default = "ft"
labels	logical indicating whether labels should be included (TRUE) or not (FALSE), default = TRUE
textSize	number describing text size of contour labels if included, default = 1.5
plotTitle	optional character string adding title to output plot

Value

ggplot object
