R Documentation

Function to find elevation from latitude and longitude coordinate pairs using Google Maps API.

Description

The Google Maps API is not open-source, therefore check the licensing conditions for usage conditions (https://developers.google.com/maps/terms). Users of this function must use the elevation data to display on a Google Map.

Usage

google_elevation(
  latitude,
  longitude,
  key,
  round = NA,
  vector = TRUE,
  progress = "none"
)

Arguments

`latitude`	Numeric vector of latitude values.
`longitude`	Numeric vector of longitude values.
`key`	Google Maps API key.
`round`	Number of decimal points to round the elevation variable to. Default is no rounding.
`vector`	Should the function only return a vector of elevation? Default is `TRUE` but a data frame can be returned with `FALSE`.
`progress`	Type of progress bar to display. Default is `"none"`.

Value

Either a data frame containing latitude and longitude pairs, elevation estimate, and (horizontal) resolution of elevation estimate or a numeric vector containing only elevation estimates.
