What Is Included in a Topographical Survey
A topographical survey maps the natural and built environment of a site. For London projects, expect surveys tied to Ordnance Survey National Grid with OS Datum heights.
Ground & Levels
- Spot heights and contours (0.5m or 1m interval)
- Slopes, level changes, ground composition
- Boundary markers and fence lines
- Retaining walls, embankments
Natural Features
- Trees with positions and canopy spreads (critical for TPOs and planning)
- Ponds, streams, water features
- Shrubs, vegetation boundaries
Man-Made Features
- Building outlines, roof profiles, outbuildings
- Kerbs, paths, roads, pavements
- Street furniture, lampposts, signposts
- Drainage covers, gulleys, drainage systems
- Utility markers and service entries
