vis_dem: Visualize dem and facc files

In brry/mhmVis: Visualisation of 'mHM' Input and Output Files, Including 'netcdf' Files

Description

Visualize mHM elevation input data: dem (Digital Elevation Model) and facc (Flow Accumulation, rivers modeled from DEM)

Usage

vis_dem(dem, proj = NA, col = demPal(1.02), rivcol = rivPal(n = 150),
  rasterriv = FALSE, prop = 0.98, pch = 15, cex = c(0.14, 0.25),
  add = FALSE, legend = TRUE, title = "Elevation", quiet = FALSE,
  rivargs = NULL, ...)

Arguments

dem	List returned by read_dem or character string giving a directory (passed to read_dem).
proj	Projection passed to read_asc. DEFAULT: NA
col	DEM color palette. DEFAULT: demPal(1.02)
rivcol	River color palette. NA will be prepended if rasterriv=TRUE. DEFAULT: rivPal(n=150)
rasterriv	Logical: should river be added as raster (with vis_asc) instead of lines (with vis_river)? Useful to examine single cells exactly. DEFAULT: FALSE
prop	Proportion of non-river, see vis_river. If rasterriv=TRUE, adjust river length with the number of colors in rivcol. DEFAULT prop: 0.98
pch, cex	Point type + size for colPoints. Only used if dem$proj != NA. Can each be two values (DEM + FACC separately). DEFAULT: pch=15, cex=c(0.14, 0.25)
add	Logical: add to existing plot? DEFAULT: FALSE
legend	Logical: add colPointsLegend? DEFAULT: TRUE
title	Character string for legend title. DEFAULT: "Elevation"
quiet	Logical: should progress messages be suppressed? DEFAULT: FALSE
rivargs	List of arguments passed to vis_asc or vis_river for FACC.
...	Further arguments passed to vis_asc for DEM, like overwrite=TRUE.

Value

Invisible list dem or read_dem result
