Crop geotrellis raster data

Crop returns a geographic subset of an gt_RasterLayer object as specified by another gt_RasterLayer object.

gt_crop(x, y)

# S4 method for gt_RasterLayer,Extent
gt_crop(x, y)

# S4 method for gt_RasterLayer,gt_RasterLayer
gt_crop(x, y)

Arguments

x

gt_RasterLayer object.

y

Extent or gt_RasterLayer object.

Value

gt_RasterLayer object.

Details

This function is similar to crop, except that y must be a gt_RasterLayer object and not just any Spatial object.

Examples

## Not run: ------------------------------------
# g <- gt_raster(raster::raster(matrix(c(1:6), ncol=3),
#                               crs=sp::CRS('+init=epsg:4326'),
#                               xmn=0, xmx=3, ymn=2, ymx=10))
# ext <- extent(c(0, 3, 2, 6))
# result <- gt_crop(g, ext)
