rasterPrep: Prepares input rasters for GARP

In cghaase/GARPTools: Tools for GARP Data Prep and Model Evaluation

Description

rasterPrep The desktop version of GARP requires all input environmental layers to be of the same spatial resolution and extent and saved as an ".asc". This function resamples input rasters to the same cell size and extent of a sample raster. User can define sample raster in res.raster or define the number of cells in each row of the raster with cells. If both res.raster and cell parameters are NULL, raster with the largest cell size will be automatically defined as the sample raster. The user can also crop rasters to a mask of the study area with mask = "mask filename".

Usage

rasterPrep(
  file.path,
  res.raster = NULL,
  cells = NULL,
  mask = NULL,
  rescale = FALSE,
  output.path
)

Arguments

file.path	location of rasters to resample and crop
res.raster	optional; a raster object to resample and crop all other rasters to
cells	optional; a numeric value representing the number of cells per row to resample rasters
mask	optional; a spatial object specifying extent to crop rasters
rescale	logical; should each raster be centered on the mean and scaled by the standard deviation?
output.path	a file path specifying where the output rasters should be saved

Value

For each raster within file.path, a new ACII file, resampled to the spatial resolution of the sample raster and spatial extent of the sample raster (res.raster) or mask file, will be returned to output.path with the same name and "_resample" appended to the file name.
