Calculates the Great Crested Newt (GCN) Habitat Suitability Index for up to 10 candidate ponds per run.
Now contains two tools. Remote Assessment tool automates SI1 - SI6 scoring (designed for fast pre-screening only). Full assessment requires field survey data. Supports per pond override to automated variables if field data is available. Includes road barrier detection to exclude habitats and ponds on far side of a road. Output is a polygon layer with per pond HSI scoring and traffic light symbology. Hope it helps.
