get_earthtones: Find the color pallette of a particular place on earth

In earthtones: Derive a Color Palette from a Particular Location on Earth

Description

Earthtones downloads a satellite image from google earth, translates the image into a perceptually uniform color space, runs one of a few different clustering algorhitms on the colors in the image searching for a user supplied number of colors, and returns the resulting color palette.

Usage

get_earthtones(latitude = 50.759, longitude = -125.673, zoom = 11,
  number_of_colors = 3, method = "pam", sampleRate = 500,
  include.map = TRUE, ...)

Arguments

latitude	center of the returned satellite image
longitude	center of the returned satellite image
zoom	generally this should be between 2 and 20; higher values zoom in closer to the target lat/long; for details see get_map
number_of_colors	how many colors do you want?
method	specifies clustering method. Options are kmeans or pam (partitioning around medoids)
sampleRate	subsampling factor - bigger number = more subsampling and less computation
include.map	logical flag that determines whether to return the satelitte image with the data object; for exploring the world leave this as TRUE; if/when you settle on a color scheme and are using this within a visualization, change to FALSE and the function will return a normal R-style color palette.
...	additional arguments passed to get_map

Details

Different parts of the world have different color diversity. Zoom is also especially important. To visualize the results, simply print the resulting object.
