At NC4 Vertical, we split our Orthographic products into two distinct categories. 'Orthographic' and '"True"Orthographic':
Orthographic
A non-georeferenced orthographic output is a stitched aerial image of your site. It provides a seamless, high-resolution overhead view that is ideal for planning and bidding tasks. Whilst the images will contain some basic geometric information, it is not 'tied' to any pixels.
Whilst it offers excellent clarity, and can be used for modelling and point clouds, it does not precisely align to real-world coordinates, meaning it cannot be used for precise measurements or engineering tasks.
"True" Orthographic
Our "True"(or geo-referenced) orthographic outputs looks similar but have one major difference: pixels are tied to real-world coordinates using a series of Ground Control Points and Check Points further combined with an RTK enabled imaging sensor. This makes the outputs spatially accurate, allowing you to measure distances, create 3d Models, Point Clouds, Digital Surface and Terrain Models or import to BIM softwares where you can overlay design drawings, and compare multiple captures over time with confidence.
This process of combining measured ground control and photogrammetry can give survey compliant accuracy to RICS D/E band outputs.
Our Orthographic services include:
High-Resolution 2D Orthomosaics
Our 2D orthomosaics give you a complete, top-down view of your entire site—accurate, detailed, and ready to measure.
- One Image, Total Clarity - No more scrolling through dozens of photos. See every ridge, seam, tile, and fault in a single, high-resolution map you can zoom, annotate, and share.
- Measure with Confidence - Take precise, real-world measurements—perfect for quoting repairs, planning installations, or managing contractors.
- Professional Reporting - Whether it’s for insurance, compliance, contractor negotiations or a client - a clean, accurate orthomosaic adds instant transparency to your inspection needs.
- Efficient - No need for repeat visits or site access—just share the image and collaborate from anywhere with your team.
Dense Point Clouds
Dense point clouds turn site imagery into millions of precise 3D points, building an ultra-detailed digital model of your project.
- Accuracy over Approximation – Point clouds are created from thousands or millions of data points, giving construction professionals confidence that measurements, dimensions, and alignments reflect reality, not assumptions.
- Flexibility – Point clouds can be imported into CAD and BIM software, forming the foundation for accurate design, retrofits, or extensions.
- Problem Detection – Unlike a standard 3D model, a point cloud reveals imperfections, deviations, or hidden clashes early, before they become expensive design issues.
- Documentation – They provide a defensible, timestamped digital record of a building or site — invaluable for heritage projects, refurbishments, or disputes.
3D Modelling
3D models and digital twins give you a powerful, interactive view of your area of interest—far beyond what photos alone can show.
- Spot Issues Instantly - Zoom, rotate, and inspect every detail from any angle—without stepping foot on a ladder, or MWEP. Ideal for identifying damage, wear, or potential leaks on your site.
- Measure Without Climbing - Take precise measurements directly from the model—ideal for quoting, planning repairs, or installing solar systems.
- Document Everything - Create a timestamped, shareable schedule of condition—essential for pre-lease surveys, dilapidations, insurance claims, compliance, or contractor accountability.
- Save Time & Money - No scaffolding. No repeated visits. Share the digital twin with your team, client, contractor or insurer and make decisions faster—with full clarity.
Annotated Site Reports
Our annotated inspection reports combine crystal-clear aerial imagery with notes, so you know exactly what’s happening and are empowered to make informed decisions.
- See It. Understand It. Act on It - We pinpoint defects, damage, and areas of concern, directly on the image, with clear, jargon-free notes.
- Shareable and Professional - Send the report to your contractor, insurer, or client. Everyone sees the same data, clearly explained.
- Document - Need evidence for insurance, compliance, or warranties? Our timestamped, annotated reports give you clear documentation to facilitate your needs.
Applications
Utilise our Orthographic products across a range of applications, such as;
- Scheduled reports
- Planned maintenance reports
- Pre-lease inspections & Dilapidations – Enable visual monitoring of progressive degradation
- Schedule of conditions of any elevation
- On site stockpile volume measurement
