Description: These habitat maps are a remotely sensed product, using CASI and LIDAR data and other GIS products.
The V1, V2 indicates where a site has been analysed for the first time or any susequent repeat surveys.
Description: This habitat map is a remotely sensed product, using CASI and LIDAR data and other GIS products.
The Habitat Maps classifications were carried out on a site by site basis, with the attribute ‘Site’ containing the site name. This product is derived from CASI multispectral data gathered on the date provided in the Attribute ‘CASI_Date’ and LIDAR elevation data gathered on the date provided in the Attribute ‘LIDAR_Date’. It also uses ground truth data collected by Natural England/ Environment Agency after the CASI capture. The year of analysis and version number of product are in the attributes ‘AnalysisYr’ and ‘Version’ accordingly
This V1 feature class analysis indicates the first time a study site has been analysed. Any subsequent repeat analysis of the site will be added to V2, V3, V4 etc feature classes.
The analysis extent for each site was defined according to ancillary data and adjusted according to field notes made during the Ground Truthing Survey.
It classifies the habitats into site relevant classes, visible at the time of CASI image capture. The attribute ‘Class’ provides the classified habitat, with some polygons also containing a 2nd habitat class in the ‘2nd_Class’ attribute. As this output layer is a merged product of many years work the class name has been updated to the most suitable recent name if it fits the current naming structure, for example Sea Buckthorn has been renamed Dune Scrub - Sea Buckthorn to bring it in line with the more up to date classification structure, these changes can be seen in the 'OldClassNa' column.

This V2 feature class analysis indicates it is the second time the study site has been analysed. To identify change in habitat classes please refer to the V1 layer for the same site.
