    dct:description """<p><font size='3'>NASADEM denotes a new 1 arc-second (30 m) global elevation
data set that is currently under development by NASA (Buckley 2015, Crippen et
al. 2016). The rationale behind NASADEM is to reprocess SRTM raw measurements
with state-of-the-art techniques in order to reduce error sources contained in
current SRTM releases. For NASADEM, auxiliary data sets such as ICESat/GLAS
laser altimetry, ASTER DEMs, GMTED2010 and national DEMs shall be together with
the Delta-Surface algorithm (Grohman et al. 2006) to fill voids in the
reprocessed SRTM data set.</font></p>

<p><font size='3'>NASADEM will be made freely available to the public. The
model release is planned for 2018. </font></p><p><font size='3'><b>Geodetic information:</b> Not yet available</font></p><p><font size='3'><b>Further notes: </b>The model has not been yet released</font></p><p style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;
