Our services
Aerial Photogrammetry
We capture thousands of overlapping aerial images and process them into precise 2D and 3D datasets. Ideal for topographic surveys, site documentation, and as-built verification.
Orthomosaic Mapping
Generate distortion-free, georeferenced aerial maps where every pixel has real-world coordinates. Perfect for GIS integration, area measurements, and visual inspection.
LiDAR Scanning
Airborne LiDAR penetrates vegetation canopy to capture dense point clouds of the terrain below. Survey-grade accuracy, verified against ground control, for floodplain studies, forestry, and corridor mapping.
3D Terrain Modeling
Digital Surface Models (DSM) and Digital Terrain Models (DTM) for grading plans, cut/fill analysis, and site visualization. Delivered in industry-standard formats.
Volumetric Analysis
Precise stockpile measurements and earthwork calculations from drone-captured data. Track material quantities over time with repeat flyovers and change detection.
Construction Progress
Scheduled flyovers document construction milestones, verify site conditions, and compare progress against design models. Keep stakeholders aligned with visual reports.

Process, equipment, and deliverables
Process
How It Works
01. Scope — We review your site, define deliverables, and plan the flight mission.
02. Capture — FAA-certified pilots execute the survey with redundant GPS and ground control.
03. Process — Raw data is processed into your requested deliverables using industry-leading software.
04. Deliver — Final datasets delivered in your preferred format with full QA documentation.

Common Questions
FAQ
What is the process for a drone survey?
Our process has four steps: (1) Scope — we review your site, define deliverables, and plan the flight mission. (2) Capture — FAA-certified pilots execute the survey with redundant GPS and ground control. (3) Process — raw data is processed into your requested deliverables using industry-leading software. (4) Deliver — final datasets delivered in your preferred format with full QA documentation.
What equipment does Twinn Digital use for drone surveys?
We operate a DJI Matrice 350 RTK with Zenmuse L2 LiDAR sensor, DJI Mini 5 Pro for visual imaging, and an Emlid RS3 GNSS Base Station for survey-grade ground control.
What file formats are drone survey deliverables available in?
We deliver in all industry-standard formats including GeoTIFF orthomosaics, LAS/LAZ point clouds, DXF/DWG CAD files, Shapefile/GeoJSON for GIS, and PDF reports with QA metrics.
What accuracy can I expect from a drone LiDAR survey?
We process LiDAR to survey-grade accuracy using the DJI Zenmuse L2 (up to 5 returns, 240,000 points per second) with RTK positioning and ground control points. Every dataset is verified against ground control, and we provide an RMSE report so you can see the accuracy achieved on your site.
What areas does Twinn Digital serve?
Twinn Digital is based in Los Angeles and travels for projects nationwide. Closer to home, we fly regularly across Los Angeles, Orange, Riverside, San Bernardino, Ventura, and San Diego counties. We hold a blanket COA for controlled airspace across Southern California, including Class B/C/D airspace around LAX and SAN.
