moveVis: Movement Data Visualization

#' Example simulated movement tracks
#'
#' This dataset contains a \code{Move} object, representing coordinates and acquisition times of three simulated movement tracks, covering a location nearby Lake of Constance, Germany. Individual names are made up for demonstration purposes.

#' White Stork LifeTrack tracks
#'
#' This dataset contains a \code{data.frame} object, representing coordinates and acquisition times of 15 White Storks, migrating from Lake of Constance, SW Germany, to Africa.
#' 
#' @details These objects are used by some \code{moveVis} examples and have been included for demonstrational purposes.
#' 
#' The dataset represents a subset of the LifeTrack White Stork dataset by Cheng et al. (2019) and Fiedler et al. (2019), available under the Creative Commons license "CC0 1.0 Universal Public Domain Dedication" on Movebank (doi:10.5441/001/1.ck04mn78/1).

#' Example manipulated NDVI data
