Abstract

The data published here are derived from Pleiades images acquired by the <a href="https://dinamis.data-terra.org"&gt; Dinamis</a> system. These data are produced for the Biotamaya project.
<br>
- The DSM (Digital Surface Model) is calculated from Pleiades images acquired in stereoscopic mode. The images were acquired in 2022 (between 16 May and 15 July 2022) and are available via the <a href="https://catalogue-dinamis.data-terra.org/"&gt; Dinamis</a> catalogue. The DSMs were calculated using the <a href="https://www.poleterresolide.fr"&gt; "pôle ForM@Ter". </a> online tool DSM-OPT (Digital Surface Models from OPTical stereoscopic very-high resolution imagery).
<br>
- The DHM (Digital Height Model) calculated by subtracting the DHM from the IGN "RGE Alti" DTM at 1m spatial resolution.
<br>
In areas covered by clouds in the Pleiades images, the data is incorrect. The Mtsamboro islet was not covered by the Pleiades images (no MNS or MNH over this area).
<br>
MNH version 2 was calculated by applying a median filter (7x7 radius) to eliminate artifacts from the IGN DTM.
