metadata2SLD.SpatialPixels: Writes a Styled Layer Description (*SLD*) file

In plotKML: Visualization of Spatial and Spatio-Temporal Objects in Google Earth

Description

Writes a Styled Layer Description (SLD) file, that can be attached to a spatial layer contributed to GeoServer.

Usage

metadata2SLD.SpatialPixels(obj, 
    Format_Information_Content = xmlValue(obj@xml[["//formcont"]]),
    obj.name = normalizeFilename(deparse(substitute(obj))), 
    sld.file = set.file.extension(obj.name, ".sld"),
    Citation_title = xmlValue(obj@xml[["//title"]]), 
    ColorMap_type = "intervals", opacity = 1, 
    brw.trg = 'Greys', target.var, ...)

Arguments

obj	object of class "SpatialMetadata"
Format_Information_Content	character; class of the object to be written to SLD file
obj.name	character; name of the layer
sld.file	character; name of the output file
Citation_title	character; title of the layer
ColorMap_type	character; type of the colorMap see https://docs.geoserver.org
opacity	logical; specifies the opacity
brw.trg	character; color scheme according to www.colorbrewer2.org; default to 'Greys'
target.var	character; target variable used to calculate the class-intervals
...	additional arguments
