In nevilamos/FAMEFMR: Functions For DELWP FAME Fire Analysis

Creates an output list containing vectors of input rasters, definintion ouf an empty output raster (by extent and resoloution) cropped to the clipPolygon provided also gets indices of cells in raster of same extent as crop to the shape provided from input and output

Description

Creates an output list containing vectors of input rasters, definintion ouf an empty output raster (by extent and resoloution) cropped to the clipPolygon provided also gets indices of cells in raster of same extent as crop to the shape provided from input and output

Usage

cropToOutput(
  REG_NO = 7,
  myRasterRes = RasterRes,
  PUBLIC_LAND_ONLY,
  myPoly = clipPoly,
  generalRasterDir = "./InputGeneralRasters"
)

Arguments

REG_NO	integer DELWP fire region number 1:6 ,99 for Statewide analysis, or 7 for ad hoc boundary polygon default =7 (see look up table REG_LUT for values)
myRasterRes	numeric raster resolution of the analysis in metres ( usually set in settings file or shiny app)
PUBLIC_LAND_ONLY	Logical TRUE/FALSE
myPoly	path of polygon file LF_REGIONs (default) or ad hoc polygon - used in conjunction with REG_NO to crop the and output rasters.
generalRasterDir	relative path to directory containing rasters of DELWP FIRE_REG, DELWP REGION, EFG, PUBLIC LAND (PLM_GEN)

Value

A list containing:

• Raster raster cropped to extent of area of interest,

• inCells integer vector cell numbers of cells in the inputRaster(s) that correspond to myPoly

• outCells integer vector cell numbers of cells in the outputRaster(s) that correspond to the inputRaster

• rasterDef an expression defining an empty raster with the correct extent for the outputRaster

• EFG integer vector EFG values for cells within clipped area

• RGN integer vector Fire Region numbers for cells within clipped area

• DELWP integer vector DELWP Region numbers for cells within clipped area

• PLM logical for cells within clipped area
