Given a coordinates vector, download the elevation data from The Google Maps Elevation API [1].

elevFromGg(data = NULL, rd.frmt = "readRDS", path = NULL,
  API.Key = NULL, starts.in = 1, round.coord = 4, save.name = "data",
  wrt.frmt = "writeRDS", save.assigned.in = NULL,
  save.unassigned.in = NULL, save.temp.in = NULL)

`data`	Vector of characters. Name of the input file.
`rd.frmt`	Vector of characters. The file format to read. By default it will be read as a R object using the `'readRDS'` argument, but it can be read as plain text using the `'readTXT'` argument. See details.
`path`	Vector of characters. Path to the input file.
`API.Key`	If the user has a google's API key, it must be used here, otherwise no more than 2500 elevations could be assigned. See details.
`starts.in`	Numeric vector. Row number where should start the process.
`round.coord`	Integer. Number of digits to keep in coordinates.
`save.name`	Vector of characters. Name of the output file.
`wrt.frmt`	Vector of characters. Format to save the output file. By default it will be written as a R object using `'saveRDS'` argument, but it can be saved as plain text using `'saveTXT'` argument. See details.
`save.assigned.in`	Vector of characters. Path to the output file with the coordinates whose elevation was assigned. Output file will be called <alt.assigned>.
`save.unassigned.in`	Vector of characters. Path to the output file with the coordinates whose elevation was not assigned. Output file will be called <alt.unassigned>. See details.
`save.temp.in`	Vector of characters. Path to the temporal file as backup of the process. If the process is stopped, the user could reset it assigning the row number in `start.in` parameter and the process will start again using temporal file.

For more details about the formats to read and/or write, see readAndWrite function.

The coordinates whose elevations were not assigned could be checked with assignElevation. This function can download directly from Google Maps Elevation API[1]

The headers of the input file must follow the Darwin Core standard [2]. The user can see the guide using data('ID_DarwinCore) command.

A table data.frame class with coordinates and their respective elevation. A table with coordinates whose elevations were not assigned. A table as backup of the process.
