PowerPoint Presentation

[Audio] Welcome everyone. Today, we will walk through the end-to-end Field Operations to Data Operations (FO-DO) Drone Survey Process Flow. Drones have revolutionized how we capture spatial data across industries—from mining and infrastructure to large-scale land mapping. Over the course of this deck, we'll examine the step-by-step workflow that guarantees safety, precision, and efficiency from initial feasibility planning all the way through to final data delivery.

[Audio] "Execution quality depends on structure. Our drone survey workflow is divided into systematic phases covering pre-deployment, field execution, and post-flight processing. We begin with Feasibility & Criteria Comparison to select the right equipment and sensors. We move into Mission Planning & GCP Placement, ensuring regulatory compliance and coordinate alignment. Next comes Resource Allocation, Equipment Testing, and Team Deployment to ensure zero field downtime. On the ground, we follow strict Pre-flight, In-flight, and Post-flight Checklists. Finally, we execute On-field Data Quality Control before passing structured deliverables into Data Management.".

[Audio] "Before diving into the operational mechanics, let's address a fundamental question: Why has drone surveying become the industry standard? Traditional ground surveys are labor-intensive, time-consuming, and often hazardous. Drones transform this process in four major ways: Unmatched Speed & Coverage: Drones can map complex, multi-hectare sites up to 10 times faster than ground teams. High Accuracy & Resolution: Using RTK/PPK sensors, we achieve sub-centimeter Ground Sample Distance (GSD) and millimetric 3D models. Enhanced Worker Safety: Surveyors no longer need to physically navigate dangerous terrain like steep mine benches or unstable slopes. Cost & ROI Efficiency: Faster capture means drastically lower operational downtime and enables high-frequency progress monitoring.

[Audio] Feasibility is where every project is won or lost. We evaluate four core decision pillars before sending a crew to the field: Accuracy & Spatial Resolution: What is the required target GSD? Do we need relative or absolute spatial accuracy? Sensor & Payload Compatibility: Should we deploy high-resolution RGB photogrammetry for open terrain, or LiDAR for heavy vegetation and steep pit walls? Airspace & Site Dynamics: Checking DGCA airspace restrictions (Red, Yellow, Green zones), terrain elevation profiles, and wind limits. ROI & Turnaround Efficiency: Ensuring the operational turnaround time offers a clear advantage over conventional surveying methods.".

[Audio] "Feasibility directly shapes mission parameters based on the application. In Mining Operations, the focus is on volumetric analysis, cut/fill calculations, and bench monitoring. This demands multirotors or heavy VTOLs equipped with LiDAR or high-res RGB, paired with GCPs along stable pit ridges. In Large Scale Mapping (LSM), the goal is wide-area cadastral boundary mapping and GIS layer generation. Here, fixed-wing or long-endurance VTOL drones equipped with full-frame photogrammetric cameras cover vast swaths of land efficiently using RTK/PPK base networks.".

[Audio] Let's talk about equipment and payload selection. First, what exactly is a payload? In the context of drones, the payload is any additional equipment the aircraft carries beyond what it needs simply to fly — cameras, sensors, delivery packages, or other specialized tools. Choosing the right payload comes down to four things at this stage. One, define your mission objectives clearly — are you doing aerial photography, surveying, crop monitoring, or something else? Two, assess weight and size constraints, because exceeding the drone's rated payload capacity affects flight stability and safety. Three, consider power requirements, making sure the battery can support both flight and the payload's needs for the full mission duration. And four, evaluate compatibility — the payload has to integrate cleanly with the drone's communication and control systems..

[Audio] Continuing our payload selection checklist. Step five is reviewing data and sensor requirements — different payloads offer different resolution, accuracy, and data formats, so match the sensor to what your application actually needs. Step six is assessing environmental conditions; some payloads are built for low light, harsh weather, or specific altitudes, so choose one that can handle the conditions on site. Step seven is evaluating data transmission needs, especially if the payload streams real-time data back to a ground station. Step eight is cost — balancing advanced features against budget and overall mission cost. And step nine is regulatory compliance, making sure the payload itself is legal to fly in your region, since some payload types carry their own restrictions..

[Audio] Here's a quick reference for the different payload types we work with and where each one earns its place. Every sensor on this slide — from RGB cameras to LiDAR units — is suited to a different deliverable, so the right choice always comes back to what the client actually needs at the end: an orthomosaic, a point cloud, or a DEM..

[Audio] These are the two airframes at the core of our fleet. The Aereo ZFR is our VTOL — vertical take-off and landing — platform, built for long-endurance, wide-area coverage where a runway isn't available. The Aereo INP is our quadcopter, suited to tighter sites, pit-level detail, and situations that call for precise, low-altitude maneuvering. Choosing between them comes down to the same feasibility questions we covered earlier: site size, terrain, and the accuracy the deliverable demands..

[Audio] Mission planning is where every successful survey begins! This is the stage where you think, prepare, and assess before flying. Good planning prevents costly mistakes and keeps the operation safe! Let's break it down: 1️⃣ Define Area of Interest – Mark the exact survey boundaries and clarify objectives; 2️⃣ Site Recce and Hazards – Visit the location, identify obstacles, cables, trees, or restricted zones; 3️⃣ Zone Classification and DGCA – Check if your area falls in a green, yellow, or red zone; obtain required permissions and NOTAMs; 4️⃣ Equipment Readiness – Inspect every component — drone, batteries, SD cards, and backup systems; 5️⃣ GCP and Benchmark Planning – Plan control point placement to ensure survey accuracy! Remember — good planning on the ground saves hours in the air!".
