Statement

The study made use of the Integrated Habitat System (IHS). A suite of aerial photography (AP) was made available to the project to facilitate habitat mapping by aerial photograph interpretation (API). The aerial imagery consisted of red/green/blue (RGB) and near infra-red (NIR) photography captured in 2018, supplied in Enhanced Compression Wavelet (ECW) format at 0.1 m pixel size, and delivered as individual 10*10 km tiles, following the Ordnance Survey (OS) reference grids. Each ECW RGB and NIR tile were converted from their original data format to GeoTiff, an Open Geospatial Consortium (OGC) recognised data format. The two datasets for each corresponding datetime (i.e. the RGB and CIR datasets for the same capture date) were combined into a single four-band dataset (i.e., blue, green, red and near infra-red), for ease of analysis and interpretation. For image segmentation purposes, the four-band dataset was resampled to 0.5 m spatial resolution to reduce the required computational power and processing speed, but maintain the required precision. Polygons for the 2018 habitat map were produced by automated image segmentation. The AP, OS OpenData and manually digitised urban areas were imported into Trimble eCognition software, and processed via a multi-resolution segmentation algorithm. Image objects were exported to polygon shapefile format for each image-processing tile. Tiles were then merged together to provide a single polygon shapefile layer per OS 10 km grid. The map was then processed and formatted by JNCC according to the EMODnet Seabed Habitats Data Exchange Format v4.1 and habitat data was translated into the EUNIS habitat classification scheme in August 2023.
