⚙️ HYBRID LiDAR + PHOTOGRAMMETRY AERIAL SURVEY: INTERLAKEN CASE STUDY

Happy Monday, everyone! 😉

We previously touched upon our comprehensive aerial survey project in Switzerland, but only gave you a quick teaser. Seeing the massive interest in hybrid survey methods right now, we’ve decided to put that right. Here is a detailed technical breakdown, focusing strictly on engineering data, flight parameters, and accuracy verification.

🔖 Key Highlights:

✅ The Site: 60 hectares of complex terrain, dense urban layout, road and rail infrastructure, and thick vegetation.
✅ The Mission: Rapid delivery of a digital archive and high-accuracy DTM within a single flight day.

⚙️ Hardware Setup & Flight Parameters
The equipment suite was built around the DJI Matrice 300 RTK UAV, with mission planning handled via UgCS Expert software:

1️⃣ Task Separation: A TOPODRONE P61 full-frame camera (61 MP, mechanical shutter) was used for RGB data capture to generate orthomosaics. Meanwhile, a TOPODRONE 200+ LiDAR (multi-echo mode) captured the terrain beneath the dense tree canopy.
2️⃣ Flight Specs: Altitude — 120 m, forward overlap — 80%, side overlap — 60%. Ground control was established using Ground Control Points (GCPs) with dedicated targets, measured via a GNSS receiver.

🖥 Data Processing & Accuracy Verification
Field data processing was split into two distinct workflows:

⏺Photogrammetry (TPP + Agisoft Metashape): The trajectory was computed in TOPODRONE Post Processing (TPP) software. The Root Mean Square Error (RMSE) on GCPs came in at: X — 2.7 cm, Y — 1.9 cm, Z (altitude) — 2.5 cm.
⏺Laser Scanning (TPP + LiDAR360): A Smoothed Best Estimate of Trajectory (SBET) was generated using GNSS (10 Hz) and IMU (200 Hz) data. In LiDAR360, the point cloud was noise-filtered and classified into ground, buildings, roads, and vegetation. The vertical RMSE was 2.8 cm.

👌 The Verdict: The RMSE for both methods remained under 5 cm, fully meeting the stringent requirements for 1:500 scale topographic mapping. The hybrid approach allowed us to clear up photogrammetry 'blind spots' under canopy using LiDAR in just a single day, delivering flawless DTMs, DSMs, contours, and orthomosaics to the client.

🌊 TOPODRONE CONDUCTS BATHYMETRIC TRAINING FOR THE UNIVERSITY OF CYPRUS

Hello everyone from sunny Cyprus! ☀️👋

Recently, the TOPODRONE team delivered an on-site training programme for specialists from the University of Cyprus. Earlier, the university had acquired the TOPODRONE AQUAMAPPER NEXTGEN bathymetric system together with a DJI Matrice 350 RTK UAV for regular monitoring of a hydraulic structure.

Several years ago, a dam near the city of Paphos failed, leaving the reservoir out of operation for an extended period. Following the restoration of the structure and the refilling of the reservoir, specialists now plan to carry out regular monthly monitoring of the reservoir bed. To support this work, dedicated training was required.

The practical sessions were conducted directly on site. A demonstration survey was performed along four survey lines spaced 25 m apart, each approximately 200 m in length. During the training, participants practised the complete operational workflow:

✅ equipment preparation and mission planning
✅ performing UAV-based bathymetric surveys
✅ field data quality control
✅ processing survey results

Initial data processing was carried out in TOPODRONE Post Processing, followed by further processing in LIDAR360.
