An orthomosaic map is a high-resolution aerial image created by stitching together multiple drone photographs into a single geometrically corrected, survey-accurate map. Our London orthomosaic surveys provide measurable aerial data suitable for planning applications, land analysis, construction monitoring and development projects.
Our experienced survey team combines RTK drone technology with advanced photogrammetry processing to deliver precise orthomosaic maps. Every project follows a structured workflow to ensure reliable, survey-grade aerial data suitable for:
We use RTK-enabled drone systems to achieve centimetre-level positional accuracy, producing measurable aerial imagery suitable for design and planning.
Orthomosaic maps provide a clear, measurable overview of sites for architects, planners and developers.
Accurate aerial data helps identify constraints, boundaries and site features early in the project lifecycle.
Residential land, commercial developments, construction sites and large open parcels.
Supplied in GeoTIFF, CAD (DWG) and PDF formats compatible with industry software.
1. Site Review & Flight Planning
We assess site constraints, airspace restrictions and project objectives.
2.Drone Data Capture
Automated grid flights capture high-overlap aerial imagery using RTK positioning.
3. Data Processing
Images are processed using professional photogrammetry software to create a geometrically corrected orthomosaic.
4. Quality Control
We verify alignment, scale accuracy and coordinate referencing.
5. Final Deliverables
You receive a high-resolution orthomosaic map ready for planning or design use.
Answers to common questions about how our surveys are carried out, what to expect on site and how the process works.
We provide professional orthomosaic mapping and drone aerial survey services throughout Greater London and surrounding areas. Our RTK drone surveys deliver high-resolution, geo-referenced aerial maps suitable for planning, development and construction projects.
