| kml_layer.STTDF {plotKML} | R Documentation |
Writes an object of class "STTDF" to a KML file with a possibility to parse attribute variables using several aesthetics arguments.
kml_layer.STTDF(obj, id.name = names(obj@data)[which(names(obj@data)== "burst")],
dtime, extrude = FALSE,
start.icon = paste(get("home_url", envir = plotKML.opts),
"3Dballyellow.png", sep = ""),
end.icon = paste(get("home_url", envir = plotKML.opts),
"golfhole.png", sep = ""),
LabelScale = 0.8 * get("LabelScale", envir = plotKML.opts), z.scale = 1,
metadata = NULL, html.table = NULL, ... )

The dateTime is defined as yyyy-mm-ddThh:mm:sszzzzzz, where T is the separator between the date and the time, and the time zone is either Z (for UTC) or zzzzzz, which represents ±hh:mm in relation to UTC. For more info on how Time Stamps work see https://developers.google.com/kml/documentation/kml_tut. If the time is measured at block support, then:
<TimeStamp><begin> </begin><end> </end></TimeStamp>
tags will be inserted. Temporal support for any spacetime class, if not specified by the user, is determined as a difference between the "time" (indicating begin time) and "endTime" slots.
