In AWAPer: Catchment Area Weighted Climate Data Anywhere in Australia

Description

getDEM get Australian 9s DEM.

Usage

getDEM(
  workingFolder = getwd(),
  urlDEM = getURLs()$DEM,
  DEMfilename = "dem-9s.asc",
  keepFiles = F
)

Arguments

workingFolder	is the file path (as string) in which to download the zip file. The default is getwd().
urlDEM	URL to the folder containing the Geoscience Australia 9s DEM. The default is taken from getURLs()$DEM.
DEMfilename	is the file name for the DEM (as string). The default is 'dem-9s.asc'.
keepFiles	is a logical scalar to keep the downloaded zip file and extracted DEM ASCII file. The default is FALSE.

Details

getDEM downloads the Geoscience Australia 9 second DEM and then imports the grid.

The DEM is required for the calculation of evaportranspiration within extractCatchmentData. For details of the DEM see https://www.data.gov.au/dataset/geodata-9-second-dem-and-d8-digital-elevation-model-version-3-and-flow-direction-grid-2008

For an example of how to download the DEM see the vignette "Extract daily area weighted potential evapotranspiration (PET) and precipitation".

Value

A RasterLayer DEM for Asutralia.
