South West Strategic Regional Coastal Monitoring Programme EMSW04 - Hartland Point to Gloucester City
This map was produced using data from the South-west Regional Coastal Monitoring Programme, commissioned by Teignbridge District Council, in this case covering the coastline between Hartland Point to Gloucester City. Through conducting a range of surveys including aerial, bathymetric, wave and tidal surveys, and ecological mapping, the programme aims to promote and implement a repeatable, standard, and cost-effective method of monitoring the coastal environment. This map is the result of the ecological mapping component of the programme, and the habitat data is presented as vector polygons using the EUNIS 2007-11 habitat classification scheme. The mapping project aimed to map the extent of all coastal and terrestrial Priority Habitats within the EMSW04 work package area covering hectares from Hartland Point, Devon to Gloucester City, Gloucestershire.

Algemene beschrijving herkomst | 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 2017/18, 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. Polygons for the 2017/18 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. The segmentation process analyses each pixel location for each specified data layer, and groups pixels of similar characteristics together to form objects, following spatial changes in land cover type. IHS habitat attribution was carried out through manual API within QGIS software. Quality assurance (QA) comprised a manual assessment of polygon attribution using the same reference material available during the API phase. The accuracy of polygon shape and transitions between habitats was also checked at this stage. Completed 10 km OS grids were submitted to the Plymouth Coastal Observatory (PCO) for review, allowing a correctional period to incorporate feedback into the final dataset, before the minimum mapping unit (MMU) was applied. The MMU describes the minimum size for features to be included into their respective habitats. The MMU process was carried out such that polygons falling below the minimum area thresholds were merged into the neighbouring polygons with which it shared the longest common boundary. The MMU process was carried out using Feature Manipulation Engine (FME) software. This map was then formatted by JNCC to meet the Data Exchange Format v4.1 required for EMODnet uploads in September 2023. |
