EO mask for spatRaster

Create mask from Landsat QA layer or Sentinel-2 SCL terra::spatRaster objects

Usage

eo_mask.rast(r, maskSnow = FALSE, maskWater = FALSE)

Arguments

r

a spatRaster object containing a layer names "qa_pixel" (for Landsat mask) or "SCL" (for Sentinel-2 mask)

maskSnow

logical. Defines whether snow should be masked.

maskWater

logical. Defines whether water should be masked.

Value

a spatRaster mask with NA for values to be masked and 0 for other values

Details

The metadata layer from which the mask is derived should be specified in maskLyr. For now, mask derived from "qa_pixel" (for Landsat) and "SCL" (for Sentinel-2) are implemented. Clouds, cloud shadow and pixels adjacent to clouds are always masked (when these fields are specified in the masking layer). Snow and water can be masked by setting the respective parameters, by default these are not masked
