Disaggregate

Disaggregate a RasterLayer to create a new RasterLayer with a higher resolution (smaller cells). The values in the new RasterLayer are the same as in the larger original cells unless you specify method="bilinear", in which case values are locally interpolated (using the resample function).

Usage
# S4 method for Raster
disaggregate(x, fact=NULL, method='', filename='', ...)
Arguments
x

a Raster object

fact

integer. amount of disaggregation expressed as number of cells (horizontally and vertically). This can be a single integer or two integers c(x,y), in which case the first one is the horizontal disaggregation factor and y the vertical disaggreation factor. If a single integer value is supplied, cells are disaggregated with the same factor in x and y direction

method

Character. '' or 'bilinear'. If 'bilinear', values are locally interpolated (using the resample function

filename

Character. Output filename (optional)

...

Additional arguments as for writeRaster
