This report documents the creation of a verified spatial dataset of England’s undesignated historic parklands. The project aimed to enhance the accuracy, completeness, and usability of an existing historic parkland dataset, which previously lacked metadata and exhibited poor spatial alignment. Using a combination of Ordnance Survey historic maps (2nd Edition and Hills Edition), high-resolution aerial imagery, and supplementary datasets such as Historic England’s Registered Parks and Gardens layer, the team systematically reviewed and revised 13,485 input polygons.
The methodology involved detailed visual and automated quality control processes, including topological and attribute checks, to ensure spatial and thematic accuracy. Key features such as shelter belts, waterbodies, lodges, and tree-lined avenues were included where identifiable. The final dataset comprises 3,777 named parklands represented by 4,517 polygons, with attributes including parkland name, area, perimeter, and administrative region. Real-time project monitoring was facilitated through ArcGIS Online, enhancing transparency and stakeholder engagement.
The report recommends future enhancements through integration of additional data sources, AI-based feature extraction, and expanded attribute fields to improve historical, ecological, and management insights.
