What We Inspect & Capture
From estate masterplanning and boundary validation to civil infrastructure and drainage topography, EntireFM delivers survey-grade aerial geospatial outputs. Utilizing RTK/PPK GNSS positioning and ground control points (GCPs), we provide millimeter-calibrated data ready for CAD, GIS, and engineering workflows.
High-Resolution 2D Orthomosaics
Georeferenced, distortion-free composite aerial maps with sub-centimetre ground sampling distance (GSD).
Digital Surface & Elevation Models
DSM and DTM elevation rasters for drainage slope profiling, flood risk modeling, and terrain analysis.
CAD & GIS Vector Integration
Export directly to DXF, DWG, SHP, GeoJSON, and LandXML for civil engineers, architects, and estate planners.
Boundary & Estate As-Built Records
Verified spatial documentation of site layouts, access roads, boundary fencing, and utility corridors.
Typical Facilities Management Applications
Real-world operational use cases where aerial drone surveys deliver maximum safety and commercial efficiency.
Estate Masterplanning & As-Builts
Millimetre-accurate topographic baselines for estate extensions and boundary validation.
Civil Drainage & Slope Profiling
Digital elevation models identifying terrain runoff slopes and flood catchment areas.
Construction Site Layouts
Pre-construction topographic surveys calibrated with RTK positioning for CAD drafting.
Infrastructure Asset Mapping
Spatial recording of private access roads, parking bays, lighting columns, and substations.
What We Look For
Common structural defects, waterproofing failures, and performance anomalies isolated during survey analysis.
Boundary Encroachment Anomaly
Visual Indicator: Discrepancy between Land Registry vector plans and physical fencing
Drainage Slope Ponding Hazard
Visual Indicator: Adverse ground fall directing stormwater runoff towards building foundations
Road Surface & Pavement Degradation
Visual Indicator: Georeferenced pothole mapping and kerb misalignment across estate yards

What You Receive
Structured, georeferenced survey deliverables formatted for property managers, structural engineers, and CAFM databases.
2D Georeferenced Orthomosaic
High-resolution composite orthophoto aligned with British National Grid (OSGB36).
Digital Elevation Model (DEM/DTM)
Topographic ground height models with 0.25m / 0.5m contour layers in DXF/DWG.
CAD / GIS Vector Integration

What happens if we
find a problem?
Surveying data is only as valuable as the estate decisions it enables. EntireFM combines aerial mapping with civil maintenance, estate grounds care, and drainage engineering to rectify surface defects, resolve boundary issues, and maintain civil infrastructure.
One Accountable Partner: We move seamlessly from inspection to investigation, quotation, specialist access, physical repair, and CAFM verification.

Frequently Asked Questions
Frequently Asked Questions
Common inquiries regarding contract scopes, SLAs, compliance audits, and onboarding.
Positional accuracy depends on survey methodology, equipment, and site conditions. When utilizing on-board Real-Time Kinematic (RTK) positioning integrated with surveyed Ground Control Points (GCPs), horizontal and vertical accuracies of 10–25mm are achievable. For non-geodetic planning and visual mapping, standard GNSS provides 1–2m absolute spatial alignment.
