<h2>DESCRIPTION</h2>

<em>r.import.ghs</em> downloads and imports Global Human Settlement (GHS) data
representing built-up area from the
<a href="https://ghsl.jrc.ec.europa.eu/download.php?ds=bu">JRC-GHS</a> website.
Data will only be imported for the current computational region.
Three datasets are currently supported for download and import:
<ul>
  <li><a href="https://ghsl.jrc.ec.europa.eu/ghs_bu2019.php">GHS-BUILT</a>,
    built-up areas derived from Landsat data, 30m resolution</li>
  <li><a href="https://jeodpp.jrc.ec.europa.eu/ftp/jrc-opendata/GHSL/GHS_BUILT_S1NODSM_GLOBE_R2018A/GHS_BUILT_S1NODSM_GLOBE_R2018A_3857_20/V1-0/">
    GHS-BUILT-S1</a>, built-up areas derived from Sentinel-1 data, 10m resolution</li>
  <li><a href="https://ghsl.jrc.ec.europa.eu/ghs_bu_s2_2018.php">GHS-BUILT-S2</a>,
     built-up area probability map derived from Sentinel-2 data, 10m resolution</li>
</ul>
