gt_resample: Resample geotrellis raster data

In jeffreyhanson/geotrellis: geotrellis: spatial data analysis using geotrellis

Description

This function resamples a geotrellis raster data gt_RasterLayer object to match the extent, resolution, and dimensionality of another projectRaster.

Usage

gt_resample(x, y, method)

## S4 method for signature 'gt_RasterLayer,gt_RasterLayer'
gt_resample(x, y,
  method = c("bilinear", "ngb"))

Arguments

x	gt_RasterLayer object.
y	gt_RasterLayer object with parameters that x should be resampled to.
...	not used.
method	character method used to compute values for the new gt_RasterLayer. Either 'ngb' (nearest neighbor), which is useful for categorical variables, or 'bilinear' (bilinear interpolation; the default value), which is appropriate for continuous variables.

Details

This function is similar to resample.

Value

gt_RasterLayer object.

g <- gt_raster(raster::raster(matrix(runif(9), ncol=3),
                              crs=sp::CRS('+init=epsg:4326'),
                              xmn=0, xmx=3, ymn=2, ymx=10))
template <- gt_raster(raster::raster(matrix(runif(4), ncol=2),
                              crs=sp::CRS('+init=epsg:4326'),
                              xmn=0, xmx=3, ymn=2, ymx=10))
result <- gt_resample(g, template, method='bilinear')
