layer.SpatialLines

Writes spatial lines to KML

Description

Writes object of class "SpatialLines*" to KML with a possibility to parse attribute variables using several aesthetics arguments.

Usage

kml_layer.SpatialLines(obj, subfolder.name = paste(class(obj)), 
  extrude = FALSE, z.scale = 1, metadata = NULL, 
  html.table = NULL, TimeSpan.begin = "", TimeSpan.end = "", ...)

Arguments

`obj`	object of class `"SpatialLines*"`
`subfolder.name`	character; optional subfolder name
`extrude`	logical; specifies whether to connect the LinearRing to the ground
`z.scale`	vertical exaggeration
`metadata`	(optional) specify the metadata object
`html.table`	optional description block (html) for each GPS point (vertices)
`TimeSpan.begin`	(optional) beginning of the referent time period
`TimeSpan.end`	(optional) end of the referent time period
`...`	additional style arguments (see `aesthetics`)

Details

Only colour and width (aesthetics) are recommended when visualizing SpatialLines* objects.
TimeSpan.begin and TimeSpan.end are optional TimeStamp vectors in the format:
yyyy-mm-ddThh:mm:sszzzzzz
Use the same time values for both TimeSpan.begin and TimeSpan.end if the measurements refer to a single moment in time. TimeSpan.begin and TimeSpan.end can be either a single value or a vector of values.

# KML plot with elevations used as 'colour' argument:
kml.file = paste0(tempdir(), "/eberg_contours.kml")
kml(eberg_contours, file.name = kml.file, 
  colour_scale = SAGA_pal[[1]], colour = Z)
