Description

featuresForElevations create and save the laters of a rasterStack containing the feature data for an elevation raster

Usage

featuresForElevations(

  rasterDir,
  shapefileDir = NULL,
  USStatevec = NULL,
  CAProvincevec = NULL,
  featureDataSource = "Shapefiles",
  writeShapefiles = TRUE,
  includeAllRoads = FALSE,
  year = 2017,
  zeroBufferTowns = FALSE,
  zeroBufferWater = FALSE,
  workProj4 = "+proj=longlat +datum=WGS84 +no_defs +ellps=WGS84 +towgs84=0,0,0",
  mapbuffer = 0,
  mapmergebuffer = 0,
  sliceFeatureBuffer = 0,
  maxRasterize = 1e+05,
  polyClean = FALSE,
  polySimplify = 0,
  polyMethod = "vis",
  polyWeighting = 0.85,
  polySnapInt = 1e-04,
  silent = FALSE,
  noisy = FALSE,
  ...
)

Arguments

rasterFileSetName	vector of names of saved raster data files
rasterDir	location to load and save raster files
shapefileDir	location to load/save shapefiles
USStatevec	vector of standard 2-letter abbreviations of US states, or pre-defined regional aggregations of states for use in defining map or finding features to include in the map
CAProvincevec	vector of standard 2-letter abbreviations of Canadian provinvces states, or pre-defined regional aggregations of states for use in defining map or finding features to include in the map
featureDataSource	"Shapefiles" to load saved shapefiles, "TIGER" to fetch TIGER data for US states, "Raster" to load saved raster data from directory specified
writeShapefiles	write/overwrite shapefiles if TIGER data is used
includeAllRoads	include all roads in shapefile, not just highways
year	numeric year to use in calls for map boundaries/features
zeroBufferTowns	use zero buffer trick to repair town polygon shapefile
zeroBufferWater	use zero buffer trick to repair water polygon shapefile
workProj4	coordinte reference projection string
mapbuffer	numeric value to expand defined map
mapmergebuffer	numeric value to expand components of the map defined before merging, to eliminate gaps from minor boundary inconsistencies
sliceFeatureBuffer	numeric value to expand the extent of the area used to estrict features befire rasterization
maxRasterize	number of items for calls to rasterize
polyClean	fix topology errors
polySimplify	amount of polygon simplification, see help for rmapshaper::ms_simplify
polyMethod	simplification method either "vis" or "dp"
polyWeighting	see help for rmapshaper::ms_simplify
polySnapInt	see help for rmapshaper::ms_simplify
silent	logical, suppress most output
noisy	logical, more output to track progress
...	values passed through
