raster (version 1.9-44)

KML: Write a KML or KMZ file

Description

Export raster data to a KML file and an accompanying PNG image file. Multi-layer objects can be used to create an animation. The function attempts to combine these into a single (and hence more convenient) KMZ file (a zip file containing the KML and PNG files).

Usage

KML(x, ...)

Arguments

x

Raster* object

...

Additional arguments (see Details)

Value

• None. Used for the side-effect files written to disk.

Details

You can use the following additional argumetns: rll{ filename output filename time character vector with time lables for multilayer objects. The lenght of this vector should be nlayers(x) to indicate "when" or nlayers(x)+1 to indicate "begin-end" col color scheme to be used (see image maxpixels maximum number of pixels. If ncell(raster) > maxpixels, sampleRegular is used to reduce the number of pixels zip If there is no zip program on your path (on windows), you can supply the full path to a zip.exe here, in order to make a KMZ file ... Additional arguments that can be passed to image }
