Drone Flight Log Book
Drones have become indispensable in modern surveying, offering faster data collection and access to difficult terrains. However, to maintain regulatory compliance, ensure data traceability, and support project documentation, every drone operator needs a systematic flight log. This Drone Flight Log Book (PDF) is designed for professional drone pilots and survey teams. It includes: Pre-flight, in-flight, and post-flight checklists Sections for pilot and observer details Fields for mission duration, GPS lock, altitude, battery cycles, wind conditions, and fail-safes Notes for remarks and incident reporting It’s perfect for BVLOS submissions, asset mapping, volumetric studies, and government tender documentation. Whether you’re flying for aerial mapping or inspection, this logbook provides the confidence that every mission is traceable and auditable. LINK to DOWNLOAD
Faculty Training on Drone Technologies for Construction
We recently had the privilege of conducting a Faculty Development Training (FDP) at Parul University, aimed at bridging the gap between traditional teaching methods and the rapidly evolving landscape of aerial surveying, GIS, and AI-powered civil engineering solutions. 🔍 Key Focus Areas:Introduction to Aerial Intelligence – Understanding how drones and smart payloads are revolutionizing topographic surveys, infrastructure monitoring, and construction planning. AI Integration in Surveying – Showcasing real-world applications of AI for crack detection, volumetric analysis, and 3D reconstruction using NeRF (Neural Radiance Fields). Hands-on Demonstration – Live demos and post-processing workflows gave faculty members a direct experience of how modern tools can enrich both research and teaching. The session was not just about tools and technology—it was about equipping educators to guide the next generation of engineers with real-world, field-tested knowledge. We extend our thanks to the Department of Civil Engineering, Parul University for hosting us and fostering such a forward-thinking learning environment. The curiosity and participation from the faculty reaffirmed our belief: when educators are empowered, the ripple effect reaches generations of learners.
Training on Advanced Surveying to Govt. Officials
🧭 From ground control to 3D models – we trained them on it all!” Proud to be a part of a training week at WALMI, Anand, where we introduced government officers to the future of Advanced Surveying using Drone Tech. ___________________ Thanks to Trishunya Consultancy and our knowledge-sharing platform BGol Community, we could deliver real hands-on value – not just presentations. We walked participants through: Looking forward to more such impactful training!
