Orthophotos and DSMs derived from RPAS flights over the nature reserve Zwin in Flanders, Belgium



The Zwin is a nature reserve situated along the Belgian North Sea coast, northeast of Knokke, in the province of West-Flanders, Flanders, Belgium. The area is managed by the Flemish Agency for Nature and Forest and consists of a tidal marsh, coastal dunes with Ammophila arenaria, dune grasslands and/or shrub (Hippophae rhamnoides, Salix repens), and a transitional grassland zone that stretches from the inner edge of the coastal dunes into the polders.

Data were collected by the Research Institute for Nature and Forest (INBO) with a Gatewing X100 drone in 2014 and 2015 (15 flights).

The raw data were processed to Digital Surface Models and orthophotos by the Flemish Institute for Technological Research (VITO) in 2017.
