Looking for fast, accurate drone surveying in Utah? Ludlow Engineering's UAV crews pair FAA Part 107-certified pilots with Utah-licensed Professional Land Surveyors, so you get survey-grade aerial data — orthomosaics, digital elevation models, 3D point clouds, and volumetric measurements — at a fraction of the cost and time of ground-only surveying. We've been Utah's land surveying and civil engineering firm since 1975, and drone-based mapping is now part of nearly every large project we touch. Call (435) 623-0897 or request a quote.
A two-person ground crew might take a week to walk and shoot a 50-acre site. A drone can map the same area in about 90 minutes at far higher point density and zero risk to surveyors on active ground. Those savings show up as both lower fees and faster project delivery.
What Is Drone (UAV) Surveying?
Drone surveying — also called UAV (Unmanned Aerial Vehicle) surveying or aerial mapping — uses small unmanned aircraft equipped with high-resolution cameras, LiDAR sensors, or both to collect spatial data from above. That raw data is then processed into the deliverables your project actually needs: orthomosaic site maps, contour drawings, digital terrain and surface models, 3D point clouds, and volumetric calculations.
For Utah projects, drone surveying answers questions ground crews answer slowly: How many cubic yards are in that stockpile? What did the site look like last month versus today? Where exactly does this 200-acre parcel slope toward the wash? Done right — with FAA-certified pilots, properly placed ground control points, and a licensed PLS reviewing the deliverables — drone data is accurate enough for the vast majority of commercial mapping, topographic, and volumetric work.
What You Get From a Ludlow Drone Survey
Every UAV survey produces a defined set of deliverables — not just "some photos." Depending on the project, your package may include any combination of the following, in the file formats your team can actually open:
Orthomosaic Map
A high-resolution, geo-referenced aerial photo of the entire site, measurable in CAD, GIS, or any modern viewer — typically 1–2 cm per pixel.
Surface & Terrain Models
DSMs and DTMs (DEMs) give accurate elevation surfaces for grading design, drainage analysis, and existing-conditions documentation.
Contour Drawings
Topographic contours at the interval your engineer needs (1′, 2′, 5′), delivered as DWG, DXF, or PDF, ready for civil design.
3D Point Clouds
Dense LAS/LAZ point-cloud files for advanced analysis in Civil 3D, AutoCAD, ReCap, Bentley, or any point-cloud-capable software.
Volumetric Measurements
Cubic-yard calculations for stockpiles, cut/fill quantities, mine and quarry inventory, and earthwork verification — with documented accuracy.
3D Site Models
Textured 3D models for marketing, planning, public presentations, and stakeholder review — embeddable on the web and in slide decks.
Progress & Time-Series Maps
Repeat flights captured weekly or monthly let you track construction progress, settlement, erosion, or vegetation change over time.
Engineer-Stamped Surveys
When the project needs a sealed, legal-grade deliverable, our in-house Utah PLS surveyors review and stamp the work — the drone is just one of our tools.
Utah Industries We Serve With Drone Surveying
Drone surveying isn't right for every job, but for the ones where it fits, it changes the economics. These are the Utah industries we work in most often:

Solar, Wind & Infrastructure
Pre-construction topos for utility-scale solar, terrain data for wind siting, and aerial mapping of linear corridors including roads, pipelines, and transmission lines.
- Utility-scale solar pre-construction topo
- Wind site terrain & access-road planning
- Linear corridor mapping
- Post-construction as-builts
Drone Surveying vs. Traditional Ground Surveying
Neither method is universally better — they answer different questions, and most of our projects use both. Here's how they compare on the dimensions that matter:
| Dimension | Drone (UAV) surveying | Traditional ground surveying |
|---|---|---|
| Speed on large sites | 50–1,000+ acres per day | 5–20 acres per day |
| Typical horizontal accuracy | 1–3 cm with proper GCPs | 5 mm – 2 cm |
| Typical vertical accuracy | 3–5 cm | 5 mm – 1 cm |
| Point density | Millions of points across the whole surface | Discrete measured shots |
| Safety on active sites | Crew stays off the operating area | Crew walks the active site |
| Best for | Topo, volumetrics, progress mapping, large parcels | Legal boundary work, control, dense vegetation, ultra-precision |
| Limitations | Weather, dense canopy, restricted airspace | Time, terrain access, line-of-sight obstructions |
The right answer is usually a combination: drone surveying for the surface data, ground crews for control points and any legal boundary corners. Because we run both in-house, you get the right method for each part of the project without coordinating two firms.

Our Drone Surveying Process
Project scoping & quote
You tell us the site, the deliverables you need, and the accuracy required. We respond with a fixed-fee quote, a timeline, and any FAA airspace considerations.
Flight planning & permits
We file required FAA notifications, plan altitude and overlap, and design the ground control point layout for your accuracy target.
Field work — GCPs and flight
The ground crew sets and surveys the control points; pilots fly the planned mission, capturing imagery and (when specified) LiDAR.
Data processing
Imagery is processed with industry-standard photogrammetry software; point clouds are filtered, classified, and geo-referenced.
PLS review & delivery
A licensed Utah Professional Land Surveyor reviews the deliverables before they leave our office. You receive files in CAD, GIS, PDF, and/or LAS.
Drone Surveying Pricing in Utah

Drone Surveying FAQ
How accurate is drone surveying compared to ground surveying?
With properly placed ground control points, drone surveying typically achieves 1–3 cm horizontal and 3–5 cm vertical accuracy. Traditional ground surveying can reach sub-centimeter accuracy when needed. For topographic mapping, volumetrics, and progress documentation, drone accuracy is more than sufficient; for legal boundary monumentation and high-precision control, ground methods are still preferred. Most of our projects use both.
How much does a drone survey cost in Utah?
Small site topos start around $1,500–$3,500. Mid-size sites (10–50 acres) typically run $3,000–$7,500. Large sites and recurring monthly flights are quoted on size, deliverables, and frequency. See the pricing table above. Every quote is fixed-fee with deliverables defined in writing.
What deliverables do I get from a drone survey?
Depending on the project: orthomosaic maps, digital terrain and surface models, contour drawings, 3D point clouds (LAS/LAZ), textured 3D models, volumetric reports, and time-series progress comparisons. Files are delivered in the formats your team uses — CAD, GIS, PDF, LAS — not in a vendor-locked viewer.
Can a drone survey replace a boundary survey?
No. Legal boundary corners require physical monumentation by a licensed Professional Land Surveyor on the ground. A drone survey produces excellent topographic and visual data, but it cannot set or verify legal corners on its own. We routinely combine the two: drone for the surface, ground crew for the corners — all sealed by our in-house PLS.
How fast can you fly a drone survey?
Field time is usually one day for sites under 500 acres. The bigger driver of the overall timeline is data processing and PLS review — typical end-to-end delivery is 2–3 weeks from contract signing. Rush turnaround is available for time-sensitive projects.
Do you have FAA-certified pilots?
Yes. All Ludlow drone pilots hold an active FAA Part 107 Remote Pilot Certificate. We file required airspace notifications and waivers, and we maintain insurance appropriate to commercial UAV operations.
Can drones map under trees or vegetation?
Photogrammetry-based drone surveys cannot see through tree canopy — only the top of the canopy is captured. Where bare-earth elevation under vegetation matters, we use LiDAR-equipped drones, which can penetrate light to moderate canopy. For dense forest, traditional ground surveying remains the most reliable option.
Do you serve clients outside central Utah?
Yes. We mobilize drone crews statewide. Travel may be reflected in the quote for distant locations, but we don't decline projects based on distance — recent mobilizations have included Salt Lake County to the north, Iron and Washington counties to the south, and eastern Utah's Carbon and Wasatch counties.
