#' VMS DB View Track Data GUI
#'
#' The \code{gui_vms_view_track} function implements the graphical user interface for the
#'  VMS DB routine to view vessel and track data with the Google Maps capabilities.
#'
#' This function, with a VMS database,
#'  plots vessel and track data on Hybrid Satellite images from Google Maps.
#'
#' @param vms_db_name The path of a VMS DataBase
#'
#' @return This function does not return a value.
#'
#' @usage gui_vms_viz_adv(vms_db_name = "")
#'
#'
#' @seealso \code{\link{gui_vms_view_ping}} \code{\link{gui_vms_view_track}} \code{\link{gui_vms_view_intrp}}
