Boeing’s Approach-to-X (A2X) software for the Army’s CH‑47F Chinook represents a supervised-autonomy architecture that blends classical flight control systems with emerging AI-driven frameworks. It reduces pilot workload by automating tactical approaches and landings, while retaining human override authority. The system exemplifies how crew‑carrying aircraft autonomy is evolving toward hybrid architectures that integrate control laws, computer vision, and agentic reasoning models.

The A2X system is built atop Boeing’s upgraded Digital Automated Flight Control System (DAFCS). At its core, DAFCS provides deterministic stability and redundancy, ensuring that autonomous maneuvers remain within certified safety envelopes. A2X extends this by embedding supervised autonomy patterns: pilots specify parameters such as landing zone, final altitude, approach angle, and start speed, while the software executes precise control inputs to achieve the trajectory. This design reflects a human-in-the-loop supervisory control pattern, common in safety‑critical aviation systems, where autonomy handles routine precision tasks but human operators retain situational authority. 

From a software architecture perspective, A2X employs modular control laws layered over sensor fusion modules. The Chinook’s avionics integrate inertial measurement units, GPS, radar altimeters, and terrain databases. These feed into autonomy modules that resemble agentic frameworks: the system interprets pilot intent (landing zone selection) and environmental constraints (terrain, glide slope) to generate control actions. While Boeing has not disclosed specific libraries, the architecture aligns with model‑based design patterns used in aerospace, where flight dynamics are encoded as state‑space models and controllers are synthesized through formal verification.

In terms of computer vision and perception, A2X itself is primarily control‑law driven, but its integration roadmap suggests coupling with vision‑language models (VLMs) and advanced perception stacks. For example, supervised autonomy in contested environments requires real‑time obstacle detection and semantic scene understanding. Here, vision libraries such as OpenCV, TensorRT, or proprietary Boeing image pipelines could be employed to process EO/IR sensor feeds. Emerging research in vision‑language models for UAVs (e.g., UAV‑CodeAgents, ReAct‑style frameworks) demonstrates how aerial systems can jointly reason over imagery and textual mission parameters, enabling adaptive landing zone selection or anomaly triage. These agentic frameworks orchestrate specialized perception modules under the guidance of a vision‑LLM “controller,” a pattern increasingly relevant for tactical rotorcraft autonomy.

The software pattern underpinning A2X can be described as a layered autonomy stack:

• Supervised autonomy layer: interprets pilot‑set parameters and executes deterministic trajectories.
• Adaptive perception layer (future integration): computer vision and VLMs for obstacle detection, semantic overlays, and tactical awareness.
• Agentic orchestration layer: frameworks that coordinate multiple specialized models (control, vision, reasoning) to ensure robustness in dynamic environments.

This layered approach mirrors broader trends in autonomous aviation: hybrid architectures that combine rule‑based flight control with learning‑based perception and reasoning agents. The Chinook’s A2X milestone—over 150 autonomous approaches with <5 ft average position error—demonstrates the reliability of supervised autonomy. 

In academic and industry contexts, such systems are often benchmarked against agentic UAV frameworks that employ multi‑agent reasoning, vision‑grounded pixel‑pointing, and mission success metrics. Boeing’s A2X, while not yet fully agentic, represents a transitional architecture: deterministic control augmented by adaptive modules, paving the way for crew‑optional heavy‑lift aircraft where autonomy handles precision flight tasks and AI frameworks extend situational intelligence.

In sum, A2X exemplifies the fusion of classical avionics with emerging AI paradigms. Its supervised autonomy architecture reduces workload while maintaining safety, and its future trajectory points toward integration with computer vision libraries, vision‑language models, and agentic frameworks—patterns that will define the next generation of autonomous, crew‑carrying aircraft.

 Zorana Ivcevic Pringle’s The Creativity Choice: The Science of Making Decisions to Turn 

Ideas into Action argues that creativity is not best understood as a rare inborn trait 

possessed by a gifted few, but as a practical, repeatable pattern of choices through which 

people transform promising ideas into work that is both original and effective. The book’s 

central claim is that creative achievement depends less on flashes of inspiration than on a 

person’s willingness to act under uncertainty, tolerate risk, and continue making decisions 

as ideas meet resistance in the real world. Pringle presents creativity as an active process 

rather than a mysterious state: people must decide what problems are worth solving, 

whether to expose unfinished work to judgment, how to respond to frustration, and when to 

revise, persist, collaborate, or pivot. Through stories drawn from artists, entrepreneurs, 

educators, designers, and organizational leaders, she shows that creative work advances 

through a series of deliberate moves that combine imagination with execution. A recurring 

theme in the book is that risk is inseparable from creativity. To produce something new, 

people must accept intellectual risk by learning unfamiliar skills, social risk by sharing 

ideas that may be misunderstood or rejected, and professional risk by pursuing paths 

whose value is not yet proven. Yet Pringle does not romanticize boldness for its own sake; 

instead, she explains how confidence for creative action can be built gradually through 

experience, observation, and support. The book emphasizes creative self-efficacy, or the 

belief that one can generate and realize worthwhile ideas, and shows how this belief grows 

when people solve small problems, see relatable models succeed, and receive 

encouragement from others. Passion, in Pringle’s account, is likewise not merely 

discovered but cultivated. People become more creative when they explore activities that 

join personal interest with developing skill, and when they remain open to unexpected 

combinations rather than confining themselves to a fixed identity. Another major 

contribution of the book is its attention to problem finding. Creative people do not simply 

answer questions handed to them; they notice overlooked tensions, gaps, and frustrations, 

then redefine problems in more generative ways. Pringle also highlights the role of emotion, 

arguing that feelings can aid creativity when individuals understand and use them 

appropriately: open, playful states may support idea generation, while more critical moods 

may help with evaluation and refinement. The book further treats creative blocks not as 

proof of inadequacy but as normal features of the process that can be addressed by 

stepping back, widening perspective, resting, seeking new stimuli, or continuing with 

small, manageable efforts. Lastly, Pringle insists that creativity is social as well as 

individual. Feedback, collaboration, conversation, and organizational climate all shape 

whether ideas survive long enough to mature. For that reason, psychologically safe 

environments—where people can question, experiment, and contribute without fear of 

humiliation—are essential to innovation. The Creativity Choice presents creativity as 

disciplined, courageous, and deeply human work: a chain of choices through which 

ordinary people can bring new and meaningful ideas into the world.

Further deliverables for Drone Video Sensing Analytics (DVSA)

Orientation and House Rules

This establishes the contract that governs the entire article. DVSA unambiguously means Drone Video Sensing Analytics — It is an acronym that refers to the software at CEJMLSubmitDVSA.docx as the authoritative primary source, with citation conventions: APA 7 for academic literature, [GH:org/repo] shorthand for GitHub repositories. DVSA is an end-to-end AI/ML pipeline that ingests drone video at scale, enriches individual frames with spatial metadata, indexes them in vector databases, and exposes the result to analysts and autonomous agents via natural-language retrieval. That pipeline description — from raw telemetry to queryable geospatial intelligence — is the unifying thread through every subsequent research direction.

Thirteen Research Themes

This article condenses the entire programme into thirteen interconnected research themes, each framed as an operational question. On ingestion, the finding is that event-driven micro-batch streaming (Kafka or Kinesis Video Streams) with idempotent writes and SHA-256/pHash deduplication is the only architecture that scales to terabytes per day without duplicating downstream embedding costs. On GPS-less localisation, the finding is that a three-stage cascade — Visual-Inertial Odometry for relative pose, Structure-from-Motion for geo-registration, and orthophoto refinement for sub-5-metre absolute accuracy — succeeds even in GPS-denied or GPS-spoofed environments. On importance sampling, the finding is that a five-filter cascade removes 65–80% of frames before embedding with less than 2% degradation in retrieval recall, making the pipeline economically viable. On vector databases and RAG, the finding is that hybrid dense-plus-sparse search over a 10-million-frame corpus achieves under 50 ms P95 latency on Qdrant, and that RAG layers ground LLM answers in actual indexed frame metadata rather than hallucinated content. On agentic retrieval, the finding is that Plan-and-Execute agents outperform ReAct on multi-hop geospatial queries, reaching 83% task-completion on three-hop benchmarks versus 71% for ReAct. On pixel-to-GPS mapping, accurate mapping is "the linchpin of any downstream geospatial query — errors here propagate through every retrieval and reasoning step." On observability, the finding is that semantic drift — measured as cosine distance between rolling embedding centroids — is the most important pipeline-health signal and should be monitored from day one. On edge vs cloud, the finding is that tiered deployment (lightweight inference on-drone, CLIP embedding on a Jetson edge node, Qdrant and LLM agents in cloud) reduces WAN bandwidth by 99.5% while keeping alert-query latency below 1.5 seconds. On security, the finding is that frame-level ACLs, AES-256 encryption, Open Policy Agent attribute-based access control, and differential privacy noise injection together satisfy both GDPR and sovereign data requirements.

Chapters 1–4: Ingestion, Localisation, and Sampling

Chapter 1 motivates DVSA with scale figures: annual drone shipments exceeding 10 million units and enterprise fleets generating petabyte-scale video archives. The core problem is labelled the semantic gap — raw frames are binary objects with no queryable meaning. Four research questions are posed, targeting sub-$0.001 per-frame ingestion, sub-5-metre GPS-less localisation, sub-100ms P95 hybrid retrieval, and >85% agentic task-completion.

Chapter 2's ingestion finding is that batch upload is insufficient: it delivers high latency, lacks streaming enrichment, and cannot attach per-frame telemetry atomically. The selected architecture — Kafka partitioned by drone_id, with three parallel consumer groups handling provenance writing, frame extraction, and deduplication respectively — achieves 4.2 GB/minute throughput, 38-second P95 end-to-end ingest latency, and verified exactly-once semantics under chaos testing. The provenance schema stores both raw GPS (which may be null) and inferred coordinates (filled later by the localisation pipeline), ensuring a complete audit trail regardless of GPS availability. Two-stage deduplication (SHA-256 exact, then pHash Hamming-distance near-duplicate via Redis Bloom filter) achieves a 67% dedup hit rate on surveillance hover missions, directly reducing downstream GPU costs.

Chapter 3's localisation finding is that VIO alone is insufficient for 10-metre accuracy targets: drift accumulates at ~0.5% of distance travelled, reaching 10 m on a 2 km flight. Stage 2 (OpenSfM reconstruction with SuperPoint+SuperGlue feature matching, which outperforms SIFT by 34% on low-texture scenes) reduces error to 8–15 m. Stage 3 (ICP registration against georeferenced orthophotos from USGS, Mapbox, or operator-generated sources) achieves 3.2–6.1 m across all tested terrain types. Each frame is also enriched with non-coordinate metadata: altitude AGL, sun elevation, ground sample distance, weather conditions, land cover class, and administrative area.

Chapter 4's importance-sampling finding is quantitative and decisive: a five-filter cascade (exact dedup, near-dedup, scene change classification, quality scoring, object-of-interest boost) reduces frames to 20–35% of raw volume while maintaining Recall@10 of 0.93–0.97 across all tested mission profiles. The scene-change classifier is a fine-tuned MobileNetV3-Small running at 850 frame-pairs/second on an A10G GPU. Object-of-interest frames — those flagged by a YOLOv8n edge detector — bypass deduplication entirely, guaranteeing that no event-containing frame is dropped.

Chapters 5–7: Retrieval, Agents, and Spatial Reasoning

Chapter 5's vector-database finding is a four-way benchmark at 10 million vectors. FAISS achieves the lowest latency (12 ms P95) but offers no persistence or metadata filtering, making it unsuitable as a standalone production store. Qdrant, selected for production, achieves 38 ms P95 with native geospatial payload filtering pushed into the HNSW graph traversal — a critical advantage over post-retrieval Python filtering. Pinecone adds zero-ops management but exceeds $800/month at scale and lacks sovereign deployment. pgvector is adequate for development corpora below 2 million vectors. Five embedding models are benchmarked: CLIP ViT-L/14 is selected as the primary frame encoder for its joint image-text space, which enables text-query retrieval without requiring prior caption generation. The RAG pipeline — CLIP text encoding of the query, Qdrant retrieval of top-20 frames, context augmentation with spatial metadata, GPT-4o grounded answer generation — is fully documented with working Python code.

Chapter 6's agentic retrieval finding is that no single agent pattern dominates across all query complexities. Function calling achieves the best simple-query performance (98% one-hop, 3.8 s average). Plan-and-Execute achieves the best multi-hop performance (83% three-hop, but at 6.1 s). ReAct with GPT-4o sits in between; ReAct with Llama-3-70B degrades sharply on complex queries (58% three-hop). The recommended production design hybridises function calling for single-step queries with Plan-and-Execute triggered automatically when the planner detects more than two required tool calls. The agent tool suite spans eight specialised functions, from semantic frame search and object counting to heatmap generation and Visual Question Answering via GPT-4o Vision.

Chapter 7's pixel-to-GPS finding is architectural: for altitudes below 500 m AGL, a flat-earth projection using camera intrinsics, drone altitude, and gimbal pitch/roll/yaw provides acceptable accuracy; above 500 m or on sloped terrain, full orthorectification against a DEM via ray-marching is required.

Chapters 8–10: Operations, Deployment, and Trust

Chapter 8's observability finding is that CPU and memory metrics are necessary but not sufficient for a semantic pipeline. The dvsa_ Prometheus metric namespace defines six purpose-built metric families: ingestion throughput and lag, localisation accuracy histograms and failure counters, embedding throughput and queue depth, retrieval latency and recall, agent task-completion rate and cost-per-query, and — most critically — semantic drift score. Drift is measured as the cosine distance between a rolling 1,000-embedding centroid and a fixed reference centroid established at index build time. A drift threshold of 0.15 triggers a Slack alert; 0.25 triggers automatic re-embedding of the affected time window. The canary query system submits ten pre-labelled queries every five minutes; if recall@10 falls below 0.85 for two consecutive intervals, Alertmanager fires. This combination means model staleness is detected within hours rather than weeks.

Chapter 9's edge-vs-cloud finding resolves a false dichotomy into a four-tier tiered architecture: lightweight INT8-quantised inference runs on-drone (YOLOv8n at 45 fps, pHash at 200+ fps, scene classifier at 60 fps); CLIP ViT-L/14 FP16 embedding runs on a Jetson AGX Orin edge node shared among five drones; Qdrant global search and LLM agent reasoning run in cloud. This tiering reduces WAN data volume from 2.5 GB/drone-hour (raw upload) to 12 MB/drone-hour (embeddings and metadata only) — a 99.5% bandwidth reduction. For time-critical alert queries, the edge-cached Qdrant instance delivers responses in 0.3–1.5 seconds versus 8–15 seconds for a cloud-only path.

Chapter 10's security finding is comprehensive but practically grounded. The threat model identifies four actors: external attackers, insiders, GPS spoofers (who corrupt the spatial index), and prompt-injection attackers who embed directives in video metadata to manipulate the agent layer. Each is mitigated concretely. AES-256-GCM at rest with customer-managed KMS keys and mTLS in transit covers the first two. VIO cross-validation with configurable discrepancy thresholds (default: 15 m) detects spoofed GPS. SQL schema allowlists and input sanitisation guard against injection. GDPR compliance is operationalised as five specific mechanisms: purpose limitation enforced at flight-plan registration, importance sampling as data minimisation, cascading deletion across provenance DB/S3/Qdrant vector, lat-lon-time frame search for data subject access requests, and automated retention-limit alerts. Differential privacy (Laplace mechanism, ε=1.0) protects aggregate analytics. Full lineage graphs track every transformation from raw frame to archived artefact, enabling compliance audits, targeted model-upgrade re-processing, and complete erasure cascades.

Chapters 11–13: Cost, Code, and Validation

Chapter 11's cost finding is its most actionable number: $0.00138 per indexed frame over a three-year, 50-drone fleet baseline, with a 3-year TCO of $371,431. The largest single cost driver is engineering labour (0.5 FTE, $225,000 over three years) — not compute or storage. Storage (S3 tiered to Glacier) costs $54,000 over three years for 750 TB of raw archive. GPU embedding is negligible ($3,942 over three years via API). LLM agent queries at 500/day cost $13,689 over three years via GPT-4o API. Sensitivity analysis reveals that the most consequential lever is eliminating edge inference: doing so adds $180,000 in WAN bandwidth costs over three years, making the $22,000 Jetson CAPEX self-liquidating within three months of fleet operation.

Chapter 12 functions as a consolidated engineering reference. It catalogues 35+ Python packages and GitHub repositories across six categories — ingestion/streaming, localisation/spatial, computer vision/embeddings, vector databases, LLM/RAG/agent frameworks, and observability/operations — each with minimum version, role, and link. Three fully annotated production-ready code examples are provided: dvsa_ingest_worker.py (Kafka consumer with exact and near-dedup, Prometheus instrumentation, and embedding queue push); dvsa_embed_worker.py (batched CLIP ViT-L/14 embedding with Qdrant upsert and throughput gauging); and dvsa_tools.py (LangChain @tool-decorated search_frames function with hybrid Qdrant query and geospatial filter construction).

Chapter 13 validates the entire pipeline through three real-world case studies and ten implementation lessons. The power line survey case study (12 DJI Matrice 350 RTK drones, 800 km of transmission lines) reduced analysis time from three weeks to four hours, saving an estimated $280,000 per survey cycle. The GPS-denied mountain rescue case study (4 fixed-wing UAVs, 40 km² alpine search area) located missing hikers 2.5 hours into the search — a 59% reduction from the 6.1-hour historical average — using VINS-Mono VIO, OpenSfM reconstruction, and a semantic colour-and-terrain query. The multi-season agricultural survey case study (8 multispectral drones, 2,400 ha) used cross-collection spatial joins and a CLIP-proxy NDVI metric to identify the highest-stress field with agronomist-confirmed accuracy, reducing the intervention area from 2,400 ha to 180 ha. The lessons distilled from across all deployments are prescriptive: provenance must be attached atomically at ingest; semantic drift must be monitored from day one; orthophotos must be refreshed quarterly; ReAct must not be used alone for multi-hop queries; embeddings must carry model-version metadata; and GPS telemetry must never be assumed trustworthy.

Conclusion:

The DVSA deliverable constitutes a complete, reproducible, and empirically validated specification for production-grade drone video intelligence at scale — from the first byte off a drone sensor to a natural-language answer grounded in georeferenced frame metadata.

 AI safety and security are primary concerns for the emerging GenAI applications. Organizations treat the defense-in-depth approach as the preferred path to stronger security for AI solutions. They also engage in feedback from security researchers via programs like AI Red Teaming and Bug Bounty program to make a positive impact to their customers. The following section outlines some of the other best practices that are merely advisory and not a mandate in any way.

As these GenAI applications become popular as productivity tools, the speed of AI releases and adoption acceleration must be matched with improvements to existing SecOps techniques. The security-first processes to detect and respond to AI risks and threats effectively include visibility, zero critical risks, democratization, and prevention techniques. Out of these the risks refer to data poisoning that alters training data to make predictions erroneous, model theft where proprietary AI models suffer from copyright infringement, adversarial attacks by crafting inputs that make model hallucinate, model inversion attacks by sending queries that cause data exfiltration and supply chain vulnerabilities for exploiting weaknesses in the supply chain.

The best practices leverage the new SecOps techniques and mitigate the risks with:

Achieving full visibility by removing shadow AI which refers to both unauthorized and unaccounted for AI. AI bill-of-materials will help here as much as setting up relevant networking to ensure access for only allow-listed GenAI providers and software. Employees must also be trained with a security-first mindset.

Protecting both the training and inference data by discovering and classifying the data according to its security criticality, encrypting data at rest and in transit, performing sanitizations or masking sensitive information, configuring data loss prevention policies, and generating a full purview of the data including origin and lineage.

Securing access to GenAI models by setting up authentication and rate limiting for API usage, restricting access to model weights, and allowing only required users to kickstart model training and deployment pipelines.

Using LLM-built-in guardrails such as content filtering to automatically removing or flagging inappropriate or harmful content, abuse detection mechanisms to uncover and mitigate general model misuse, and temperature settings to change AI output randomness to the desired predictability.

Detecting and removing AI risks and attack paths by continuously scanning for and identifying vulnerabilities in AI models, verifying all systems and components that have the most recent patches to close known vulnerabilities, scanning for malicious models, assessing for AI misconfigurations, effective permissions, network resources, exposed secrets, and sensitive data to detect attack paths, regularly auditing access controls to guarantee authorizations and least-privilege principles, and providing context around AI risks so that we can proactively remove attack paths to models via remediation guidance.

Monitoring against anomalies by using detection and analytics at both input and output, detecting suspicious behavior in pipelines, keeping track of unexpected spikes in latency and other system metrics, and supporting regular security audits and assessments.

Setting up incident response by including processes for isolation, backup, traffic control, and rollback, integrating with SecOps tools, and availability of an AI focused incident response plan.

In this way, existing SecOps practices that leverage well-known STRIDE threat modeling and Assets, Activity Matrix and Actions chart with enhancements and techniques specific to GenAI.

 The current phase of the AI agent economy is defined by a tension between undeniable productivity gains and uneven monetization, a pattern made clear in recent industry reviews. Across tens of thousands of surveyed users, the strongest signal is that AI is already expanding the amount and type of work individuals can complete. Users report “substantially more productive” outcomes, with 48 percent citing expanded scope of work and 40 percent citing faster execution . These gains are real, measurable, and broadly distributed, yet they do not automatically translate into durable revenue for the companies building these systems. The market is now shifting from hype-driven visibility to a more sober evaluation of where AI actually changes operating leverage.

Commercial traction is emerging most clearly in enterprise environments where workflows are frequent, outcomes are quantifiable, and cost structures are well understood. Customer support illustrates this dynamic: organizations with high ticket volumes and predictable service metrics can immediately measure the impact of automation on cost per interaction. Even modest deflection rates of 20 to 50 percent materially improve margins at scale, making support automation one of the earliest reliable revenue categories. Similar logic applies to sales and revenue operations, where AI agents that automate CRM updates, summarize calls, or draft follow‑ups increase productive selling hours without increasing headcount. In engineering and internal operations, the value proposition is even more direct because skilled labor is expensive and capacity constrained. Tools that reduce debugging time or accelerate documentation by even 20 to 40 percent can outperform many back‑office use cases despite smaller user counts.

The reviews emphasize that Southeast Asia’s SME landscape may represent an underappreciated opportunity. Small and medium enterprises in the region often operate with lean teams and fragmented systems, making AI agents for invoicing, scheduling, multilingual messaging, and collections immediately valuable. These are environments where owner‑level productivity gains translate directly into willingness to pay. The broader pattern is consistent: enterprises pay for AI when it improves labor efficiency, shortens cycles, or generates measurable operating returns.

At the same time, the labor implications are complex. Productivity gains do not necessarily reduce anxiety about job security. The survey shows that roughly one‑fifth of respondents fear displacement, with early‑career workers expressing the highest concern. One article cites that “users who reported the largest speed gains… were also among the most concerned about job loss” . This creates a two‑speed labor market in which junior and repetitive tasks are automated first, potentially compressing the traditional pipeline through which future managers and specialists develop. The next phase of value creation may therefore come not from replacing workers but from enabling one skilled employee to manage the output of multiple AI systems.

Where hype outpaces revenue, the pattern is equally clear. Consumer‑facing general agents attract attention and experimentation, but retention is inconsistent and pricing power is weak. As foundation models improve, standalone wrappers with limited differentiation face increasing pressure. Products with high inference costs but low willingness to pay may show strong usage while generating weak margins. The market increasingly rewards repeat usage, clear ROI, and defensible workflow integration rather than viral adoption.

From an investor perspective, the next winners may appear less glamorous but more economically durable. Metrics such as fast payback periods, high usage frequency, low churn, expansion revenue, proprietary data loops, and strong margins are the most reliable signals of long‑term value. Products embedded deeply into CRM, ERP, ticketing, finance, or operational systems create switching costs that general assistants cannot match. Vertical AI in healthcare administration, legal review, finance operations, logistics, and industrial workflows may therefore outperform broader consumer‑oriented tools.

This reinforces that the majority of AI’s current surplus accrues to individuals rather than institutions. Around 70 percent of respondents say the primary beneficiary of AI productivity is “me,” while only about 10 percent point to employers or clients . This suggests that adoption is still user‑led rather than enterprise‑captured. Historically, technologies such as search, social platforms, and cloud software followed similar trajectories: utility emerged first, monetization matured later. The next stage of the AI agent economy will depend on converting personal productivity gains into enterprise budgets through workflow integration, measurable outcomes, and recurring value.

 Drone Survey Area reconstitution:

Problem statement:

Aerial drone images extracted from a drone video are sufficient to reconstitute the survey area with image selection to create a mosaic that fully covers the survey area. This method does away with the knowledge of flight path of the drone. Write a python implementation that places selections from the input on the tiles in a grid to increase the likelihood of match with the overall survey area.

Solution:

The following is a visual survey approximation, not a georeferenced orthomosaic. Without GPS/EXIF or camera poses from the previous example, the script cannot know the true ground positions, so the grid is an informed montage rather than a mathematically correct map.

Usage:
