intersect_masks: Intersect Two Masks

In rebeccalpowell/grassmapr: Predict C3/C4 Grass Distribution

Description

Intersects two masks to identify cells that meet both criteria for corresponding layers. Grid cells that satisfy both criteria are reclassified as 1, grid cells that fail at least one criteria are reclassified as 0.

Usage

intersect_masks(temp.mask, precip.mask, filename = "", ...)

Arguments

temp.mask	Raster* object. Mask of grid cells that meet minimum temperature threshold, may be result of mask_grids. Object may be single or multi-layer.
precip.mask	Raster* object. Mask of grid cells that meet minimum precipitation threshold, may be result of mask_grids. Object may be single or multi-layer.
filename	Character. Optional output root filename passed to writeRaster, default output file type is GeoTiff. If not specified, output is written to a temporary file.
...	Other arguments passed to writeRaster.

Value

RasterBrick. One output mask layer for each input layer. If filename is specified, output file format is GeoTiff with unsigned integer data type.

Examples

# Generate masks of grid cells that satisfy C4-climate criteria
C4_mask <- intersect_masks(C4_temp_mask, precip_mask)

# Generate masks of grid cells that satisfy growing-season climate criteria
GS_mask <- intersect_masks(GS_temp_mask, precip_mask)

# Plot monthly growing-season masks
plot(GS_mask)
