kml_track

Generate KML from locations

Description

Function to generate a kml file from tracking data. This is a wrapper of plotKML and kml, specifically designed to generate a kml file from tracking data.

Usage

kml_track(sdata, sdata.CRS = "WGS", output = "open", type = "point", ...)

Arguments

`sdata`	A data frame containing location data of one individual, with the following column headers: "id", "DateTime", "lat", "lon". "id" is an identifier of the individual. "DateTime" is the GMT date & time of each location in class `POSIXct` or `character` with the following format "2012-06-03 01:33:46". "lat" and "lon" are the latitude and longitude of each location in decimal degrees.
`sdata.CRS`	Coordinate reference system (CRS) for the input location data. If the input data is not in WGS, the specific CRS needs to be supplied as a PROJ.4 notation or EPSG code. (e.g. "+proj=utm +zone=37 +datum=WGS84 +units=m +no_defs" or "EPSG:32637")
`output`	A string specifying whether to 'open' or 'save' the output. The output will be saved in the current working directory.
`type`	Type of the output. 'point' or 'line.
`...`	Optional arguments passed to `plotKML` and `kml`.

Value
