terra (version 1.6-17)

disagg: Disaggregate raster cells or vector geometries

Description

SpatRaster: Create a SpatRaster with a higher resolution (smaller cells). The values in the new SpatRaster are the same as in the larger original cells.

SpatVector: Separate multi-objects (points, lines, polygons) into single objects.

Usage

# S4 method for SpatRaster
disagg(x, fact, method="near", filename="", ...)
# S4 method for SpatVector
disagg(x)

Value

SpatRaster

Arguments

x

SpatRaster or SpatVector

fact

positive integer. Aggregation factor expressed as number of cells in each direction (horizontally and vertically). Or two integers (horizontal and vertical aggregation factor) or three integers (when also aggregating over layers)

method

character. Either "near" for nearest or "bilinear" for bilinear interpolation

filename

character. Output filename

...

additional arguments for writing files as in writeRaster

Examples

r <- rast(ncols=10, nrows=10)
rd <- disagg(r, fact=c(10, 2))
ncol(rd)
nrow(rd)
values(r) <- 1:ncell(r)
rd <- disagg(r, fact=c(4, 2))
