Build an initial site constraints pack covering levels, ground conditions, planning and flooding. Compare listed sources, access requirements and evidence for civil engineering site assessment data.
Desk study evidence needs walkover and survey verification before detailed civil design.

Desk study: nearest borehole records for ground conditions at a site · Preliminary geology and fault screening from 1:50 000 bedrock mapping · Identifying non-coal mining plans and parent material as site constraints
New GeoIndex v1.24.0 is in beta; professional and commercial users are advised to use the existing applications for now · Current onshore and offshore applications are due to be replaced, so the platform may change · Some data layers may be presented differently in the newer application · No warranty on quality, accuracy or completeness of the map data · 3D models are only available for London, Cardiff, Glasgow and Liverpool
planning and housing datasets (over 100) · conservation areas · listed buildings (with listed_building_grade) · brownfield land · planning applications (spec in development) · flood risk zones · Article 4 directions · green belt · scheduled monuments · SSSI · ancient woodland · heritage at risk · AONB · tree preservation zones · local planning authority boundaries
No authentication (auth: none); licence OGL-3.0 per catalogue metadata
Useful for
Use cases llm-inferred
Planning constraint check for a site or property by UPRN or coordinate (conservation area, listed building, flood risk zone, Article 4) · Brownfield land and planning application screening within an LPA boundary for site appraisal · Heritage and environmental designation baseline for a property (listed buildings, SSSI, ancient woodland, scheduled monuments) · Portfolio planning-risk screening of multiple properties via bulk CSV/GeoJSON downloads
Beta service; API may change · Planning applications spec in development; local planning authorities not required to share application data · No batch endpoint; one request per property · Absence of results does not mean no constraints; data coverage varies by area · Apply polite rate-limiting between requests
flood risk information for planning applications · printable flood map for planning · detailed flood risk data

Use cases
Screening whether a planning application needs a flood risk assessment in England · Pulling flood zone extents for a site's flood risk section of an FRA · Ordering detailed flood risk data for a drainage or flood risk baseline
National strategic screening data; a site-specific flood risk assessment may require detailed local modelling. · NaFRA2 accounts for flood defences; planning flood zones have a distinct statutory planning purpose.
Which listed sources support Civil engineering site assessment data?
Start with Defra Data Services Platform LiDAR, BGS Geoindex, planning.data.gov.uk. Build an initial site constraints pack covering levels, ground conditions, planning and flooding.
What should I check before using these sources for civil engineering site assessment data?
Desk study evidence needs walkover and survey verification before detailed civil design.
How do I inspect Defra Data Services Platform LiDAR through MCP?
Connect an MCP client to https://terramcp.earth/mcp and call get_source with slug defra-data-services-platform-lidar. Review its provenance, access requirements and limitations before contacting the upstream service. Discovery does not make every listed source directly executable through the router.
Are these sources free and independently verified?
Access and licence terms belong to each upstream provider; some products require registration or payment. Open each listing for evidence, health status and enrichment provenance. A wrapper and its underlying API can refer to the same dataset and are not independent observations.
