Title

EUNIS ANNEX I habitat map for Bassurelle Sandbank SCI

Abstract

EUNIS ANNEX I habitat map for Bassurelle Sandbank SCI (CEND 03/13). An ArcGIS polygon shapefile of the potential extent of Annex I sandbank habitat identified at Bassurelle Sandbank SCI was created using the data collected and processed as described as follows. EUNIS class assignments from the particle size data were used in conjunction with the interpreted still images to inform the semi-automated process of map production using object-based image analysis (OBIA), implemented in the software package eCognition v8.8.1. The OBIA was used to map habitats. It was not possible to use this technique for the mapping of Annex I habitats (specifically the sandbank feature at Bassurelle Sandbank SCI). Instead, an expert driven process of slope analysis in ArcGIS 9.3.1 and 3D visual interpretation using the Fledermaus v7 software package was used to identify the potential extent of the bank feature.
