exportAsGDAL: Export result grid as GDAL grid map

Description

This function exports the result grid as a GDAL grid map.

Usage

exportAsGDAL(grid, shift, resolution, directory=getwd(), filename="grid.tif", drivername="GTiff")

Arguments

grid

The grid that should be exported.

shift

The geographic coordinates of the origin of the grid.

resolution

The resolution of the grid in (geographical) degree.

directory

The directory in which the file will be created.

filename

The name of the created file containing the GDAL grid map.

drivername

Determines the format of the resulting GDAL grid map. All available drivers can be shown by using the command 'gdalDrivers()'.

Details

This routine exports a grid as an GDAL grip map. The package rgdal is required.

Examples

##load data
data(dataset.all.species)
data(dataset.landwater)

##create grid parameters
dimension <- getDimension(dataset.all.species, resolution=1)
shift <- getShift(dataset.all.species)

##create landwatermask
landwatermask.nocoast <- createLandwatermask(dataset.landwater, 
						dimension, shift, resolution=1)

##estimate species richness
species.richness.weighted <- species.richness(dataset.all.species,
landwatermask.nocoast, distances=1:10, weight=0.5, dimension,
shift, resolution=1, upperbound=3000, all.species=1:20)

##export
exportAsGDAL(species.richness.weighted, shift, resolution=1, 
	    directory=getwd(), filename="species.richness.tif", drivername="GTiff")
