RTK Drone Survey & Digital Twin
WE SCAN BEFORE WE CLEAR OR DIG.
WE PROVE WHAT WE MOVE.
Survey-grade RTK drone mapping delivers ±0.5cm accuracy before, during, and after every project. Every cubic yard billed is a cubic yard verified. Every deliverable is georeferenced, timestamped, and CAD/BIM-ready.

How It Works
FROM FLIGHT TO DELIVERABLE.
48 HOURS. NOT 4 WEEKS.
Traditional survey crews take 2–4 weeks and charge $3,000–$8,000. Our RTK drone survey captures the same data in 15 minutes, processes overnight, and delivers a shareable 3D model within 48 hours.

Pre-Mobilization
PHASE 01 — BEFORE THE FIRST BUCKET
WE SCAN BEFORE WE DIG.
Most contractors show up with a machine and a gut feeling. We show up with a Mavic 3 Enterprise RTK drone that maps your site to ±0.5cm horizontal accuracy before a single bucket moves. Heritage trees get a Critical Root Zone boundary. Drainage flow lines get modeled. Rock shelves get located. Every variable that causes change orders on other jobs gets accounted for on this one.

Technical Specifications
THE SPEC SHEET.
NOT MARKETING FLUFF.
| Specification | Detail | Why It Matters |
|---|---|---|
| Horizontal Accuracy | ±0.5cm with RTK corrections | Eliminates disputed yardage. Accurate enough for civil engineering grade checks. |
| Vertical Accuracy | ±1.0cm with RTK corrections | Critical for cut/fill volumetrics and drainage flow modeling. |
| Ground Control Points | Not required (RTK positioning) | Saves 2–3 hours per site. No survey crew needed for GCP placement. |
| Flight Time per Site | 10–15 minutes automated | Minimal site disruption. Flight happens while crew mobilizes equipment. |
| Processing Time | Same-day to 24 hours | DroneDeploy cloud processing. No local hardware bottleneck. |
| Deliverable Turnaround | 48 hours from flight to report | Traditional surveys take 2–4 weeks. This changes the project timeline. |
| Output Formats | .las, .laz, GeoTIFF, .dwg, .rvt, .obj | Native import into AutoCAD, Civil 3D, Revit, Procore, and most GIS platforms. |
| Coordinate System | NAD83 / WGS84 (configurable) | Matches your engineer's datum. No coordinate translation errors. |
| Drone Operations | FAA Part 107 certified pilots | Fully legal. Fully insured. All flights comply with FAA regulations. |
| Data Hosting | DroneDeploy cloud (perpetual access) | No software installs. Shareable via browser link. Annotations persist. |
Data Ownership & Terms
YOUR DATA.
CLEARLY DEFINED.
Every ClearGround project includes clear terms on data ownership, usage rights, and liability boundaries. No ambiguity. No surprises.
Data as System of Record
In the event of a dispute regarding soil volume, rock removal, or material imported, ClearGround's RTK-verified drone data and InSite reports serve as the primary system of record for billing. This stops the "my guy said he moved more dirt" argument before it starts.
Pre-Backfill Verification
Once a utility or footing is backfilled, the SiteScape/LiDAR scan constitutes the final evidence of as-built conditions. Client has 24 hours post-scan to dispute installation quality before backfill occurs.
Intellectual Property
ClearGround retains all IP rights to raw data, flight paths, and processing methodologies. Upon final payment, client receives a non-exclusive, perpetual license to use deliverables for maintenance, repair, and marketing of the specific project site.
Liability Boundaries
Deliverables represent as-built conditions at a specific timestamp. ClearGround is not liable for site changes occurring between scheduled scans. BIM models do not supersede stamped drawings of the Engineer of Record or Architect.
Professional Standard of Care
All digital captures performed using industry-standard RTK corrections to ensure centimeter-level accuracy. All drone operations conducted by FAA Part 107 certified pilots in compliance with federal regulations.
Marketing Rights
Unless otherwise agreed in writing, ClearGround reserves the right to use anonymized site scans and time-lapse footage for marketing and portfolio purposes. Client data is never shared with identifiable details without consent.
Who This Is For
EVERY ICP.
DIFFERENT DATA.
The same technology platform, adapted to what each client actually needs from it. The data is the constant. The framing changes.
