Setup DEM for inundation modeling

DEM_setup(
  pipes,
  other_network_layers = NULL,
  large_DEM,
  elev_units = "m",
  conversion_raster,
  res = 9.81,
  trace_upstream = F,
  trace_buffer = 1.5,
  extent_buffer = 1000,
  minimum_area = 2,
  workspace,
  overwrite = F
)

Arguments

pipes	A `sf` object denoting stormwater pipes.
large_DEM	`RasterLayer` DEM to be processed
conversion_raster	`RasterLayer` Conversion from NAVD88 to MHHW
res	Desired spatial resolution of output DEM (meters)
trace_upstream	Logical. Trace NAVD88/MHHW conversion factor upstream?
trace_buffer	Buffer distance (map units of pipes) around pipes to search for receiving waters
minimum_area	km^2. Minimum area of flooding to keep as "downstream flooding"
workspace	Path to bathtub folder
overwrite	Logical. Overwrite existing data?
other_network_layer	Vector of `sf` objects to be included in network

Value

DEM clipped to stormwater network, reprojected to projection of pipes, and values converted from NAVD88 to MHHW

Examples

# site_DEM <- bathtub::DEM_setup(
# pipes = site_pipes,
# large_DEM = NC_DEM,
# conversion_raster = NAVD88_MHHW_conv,
# res = 5,
# workspace = site_workspace
# )
