#' @title _Aedes aegypti_ occurrences in Brazil in 2013
#'
#' @description A geographic dataset of known occurrences of _Aedes aegypti_

#' \item{location_type}{point or polygon location}
#' \item{polygon_admin}{admin level or polygon size; -999 for point locations}
#' \item{y}{latitudinal coordinate of point or polygon centroid}
#' \item{x}{longitudinal coordinate of point or polygon centroid}

#' Data pre-processing:
#' After acquiring data from above links, we converted any dataset
#' embedded in PDF format to CSV. Using carried functionalities in the CSV
#' file, we sorted all datasets alphabetically based on state names to make
#' later iterations more convenient. Also, we calculated the annual average
#' temperature and added to the original dataset where it was documented by
#' quarter.
