How can DHA assist your development using GIS?
Our Geographical Information System (GIS) service produces maps that help visualise data, identify patterns and support decision-making. Our planning, transport and environmental teams use it for analysis and presentation throughout their professional reports.
Environmental Statements
- Sensitive receptor plans showing local environmental designations, such as Sites of Special Scientific Interest, European sites and heritage assets
- Cumulative site assessments
- Agricultural land grade boundaries and values
Planning Reports and Local Plan Promotion
- Strategic maps of development constraints such as Green Belt, flood risk and Areas of Outstanding Natural Beauty, like our free Interactive Map
- Land ownership boundaries
- Site elevations and topography using LiDAR
- Census data analysis within a defined area
- Land promotion, site allocation and strategic data to support Local Plan consultation responses
- Custom maps and graphics for reports
Transport Assessments
- Walking, cycling and drive-time analysis showing exact travel times from a site
- Transport isochrones showing the services around a site
- Postcode mapping, for example to show where employees or members are based
- Key transport links, and proposed new links
- Public rights of way and cycle routes around a site, to demonstrate sustainability
- Heat maps showing the density of data across an area
