gt_raster: Create geotrellis raster object
In jeffreyhanson/geotrellis: geotrellis: spatial data analysis using geotrellis

Description Usage Arguments Details Value See Also Examples

This function creates a geotrellis raster object (gt_RasterLayer).

gt_raster(x, ...)

## S4 method for signature 'character'
gt_raster(x)

## S4 method for signature 'RasterLayer'
gt_raster(x)

## S4 method for signature 'ANY'
gt_raster(x, ...)

`x`	input object.
`...`	additional arguments passed to `raster` if `x` is not `character` or `raster`.

This function essentially loads x into geotrellis as as raster data using the following methods:

character objectx is treated as a file path for raster data loaded directly into the Scala interpreter.
RasterLayer-class objectx is saved to disk and loaded into the Scala interpreter.
otherwisean attempt is made to coerce x to a RasterLayer-class object and then it is saved to disk and loaded into the Scala interpreter.

gt_RasterLayer object.

raster.

# create gt_raster object using a raster
g1 <- gt_raster(raster(matrix(1:4, ncol=2)))
# create gt_raster object using a geotiff path
g2 <- gt_raster(system.file('extdata', 'test.tif', package='geotrellis'))
# create gt_raster object using default method
g3 <- gt_raster(matrix(1:4, ncol=2))
