By utilising point cloud data captured during a single laser survey, a precise topographical survey can be produced — delivering an accurate digital representation of your site's terrain, features, levels and boundaries.
Topographical surveys are specified across a wide range of construction, civil engineering, planning and development projects where an accurate understanding of existing site conditions is essential before design begins. Clients use them for planning applications, drainage design, earthworks calculations, highway design and infrastructure projects. These surveys provide a reliable, detailed picture of the site that desk studies and basic site visits cannot replicate.
One of the key advantages of a laser-scanned topographical survey is the density and accuracy of the data captured. Terrain levels, existing structures, vegetation, kerb lines, drainage features, boundary positions and utility covers are all recorded in a single site visit — producing both 3D surface models and 2D CAD drawings to any required level of detail and to a national or site-specific coordinate system.
Georeferenced to Ordnance Survey
Topographical surveys can be delivered fully georeferenced to Ordnance Survey National Grid and referenced to Ordnance Datum Newlyn — providing accurate, compatible data for use alongside OS mapping.
TOPOGRAPHICAL SURVEYApplications
PLANNING APPLICATIONS
Provide accurate existing site data to support planning submissions and pre-application enquiries/
DRAINAGE DESIGN
Capture existing levels and features to inform surface water, foul and highway drainage design/
EARTHWORKS & VOLUMES
Calculate accurate cut and fill volumes for groundworks, landscaping and earthworks contracts/
HIGHWAY & INFRASTRUCTURE

UTILITIES & SERVICES MAPPING
Capture above-ground utility features including covers, poles, cabinets and apparatus positions/
A topographical survey gives designers, planners and engineers an accurate picture of what is actually on site — before a single drawing is produced
A scaled 2D plan showing all surveyed site features including structures, boundaries, vegetation, drainage, kerb lines and utility apparatus in their correct positions /
Cut-through drawings along or across the site showing ground profile, levels and gradients at specified alignments for drainage, highway and infrastructure design /
A drawing or data table showing absolute surveyed levels at regular grid intervals across the site, used for volumetric calculations, setting out and surface modelling /
