Miotti's diary records roughly 1,200 km² of lidar rendered and 48 agent passes over October 19, with Gemini, ChatGPT, Claude and Grok used for brainstorming, overnight tile review, literature search, report drafting and Spanish translation. The result is not a confirmed archaeological discovery; Miotti sent coordinates in a confidential annex and offered field help only under INAH authority, with field verification still requiring INAH-led work.", "body_md": "**In October 2026 Pietro Miotti published a [first-person account](https://pietromiotti.com/latest/maya-site/?ref=explainx) of using **multimodal AI agents** and **public lidar** to flag a **Maya hilltop** with plaza, pyramid, and courtyard shapes under jungle canopy—and receiving an **[INAH](https://www.inah.gob.mx/?ref=explainx)** reply that **no registered archaeological site** sat at the coordinates he reported.** The story spread on [Hacker News](https://news.ycombinator.com/item?id=50449945&ref=explainx) as a rare **non-coding** agent win: **science workflow** in **under 72 hours**.\n\nIt is **not** a confirmed archaeological discovery. It **is** a concrete template for how **general agents**, **public Earth observation data**, and **government inboxes** interact when a motivated outsider runs an experiment responsibly.\n\n## TL;DR\n\n| Step | What happened (per Miotti's diary) | \n|---|---|\n| Oct 18 | Idea after reading about Hiram Bingham; agents suggest **lidar** over Maya region | \n| Oct 19 | ~ **1,200 km²** lidar rendered;**48 agent passes** flag geometric sites | \n| Oct 19–20 | Agents check literature; one hilltop **not found** in cited archives | \n| Oct 20 | Report translated to Spanish; sent to **INAH** with confidential coordinate annex | \n| Oct 21 | INAH email: **no registered site** at reported location | \n| Status | **Not official** discovery; field verification needs INAH-led work | \n\n## Why lidar—and why agents?\n\nFrom orbit, a jungle ruin is **just trees**. [Miotti's post](https://pietromiotti.com/latest/maya-site/?ref=explainx) explains that **lidar** pulses through canopy gaps and maps **bare-earth elevation**, revealing straight edges and platforms satellites miss.\n\nHe explicitly says there was **no special classifier**: agents **looked at pictures** following a guide, like patient human surveyors at scale. That is closer to [remote labor benchmarks](https://explainx.ai/blog/remote-labor-index-fable-5-2-automation-rate-scale-cais-2026) than to a bespoke foundation model—**orchestration + vision** over **strips** already collected for environmental research (he cites NASA **G-LiHT** and reuse papers).\n\nThe hilltop he highlights shows a **levelled plaza**, an **8–12 m** pyramid mass, a **raised courtyard**, and a **flat-bottomed hollow** that might have stored water—classic **Maya civic-centre** morphology in his interpretation.\n\nAI agents flagged Maya civic centre structures in bare-earth lidar under jungle canopy\n*Image: [Pietro Miotti](https://pietromiotti.com/latest/maya-site/?ref=explainx)*\n\n## The agent stack Miotti actually used\n\nMiotti names **Gemini**, **ChatGPT**, **Claude**, and **Grok** across the diary—not one vendor bet. Tasks split naturally:\n\n- **Brainstorming** data sources and regional coverage\n- **Overnight batch review** of rendered lidar tiles\n- **Literature and archive search** for prior registrations\n- **INAH process instructions** and email addresses\n- **Report drafting** and**Spanish translation**\n- **Point-cloud sanity checks** separating canopy returns from ground\n- **Artistic reconstruction** visualization (explicitly labeled generated)\n\nThat mirrors how practitioners already mix models in [useful Claude Code agent projects](https://explainx.ai/blog/build-useful-ai-agents-claude-code-2026) and [agent skills](https://explainx.ai/blog/what-are-agent-skills-complete-guide) workflows: **specialists per subtask**, human review between **irreversible** steps.\n\n### What was not automated\n\nMiotti sent coordinates in a **confidential annex**, iterated the report when agents got details wrong, and offered **field help only under INAH authority**—required under **Mexican federal heritage law** he acknowledges. Agents did **not** loot, dig, or publish precise GPS in the public post.\n\n## INAH's reply—and what it does and does not mean\n\nINAH reply that no registered archaeological site existed at the AI-reported coordinates\n*Image: [Pietro Miotti](https://pietromiotti.com/latest/maya-site/?ref=explainx)*\n\nMiotti screenshots INAH's October 21 answer: **no registered archaeological site** at the location in his report. That is **administrative novelty**, not a peer-reviewed paper.\n\nPossibilities archaeologists routinely consider:\n\n- A **genuine unmapped** civic centre awaiting ground truthing\n- A **known feature** present in lidar catalogs Miotti's agents did not query completely\n- A **natural geomorphology** misread as platforms (less likely when multiple aligned structures appear)\n\nThe blog is transparent that interpretation after INAH's note remains **speculation**—Classic-period civic centre, elite compound, possible **aguada** reservoir.\n\n## What developers are saying on Hacker News\n\nThe [HN thread](https://news.ycombinator.com/item?id=50449945&ref=explainx) is thin but substantive. User **ks2048** ([comment](https://news.ycombinator.com/item?id=50450462&ref=explainx)) argues large lidar campaigns already catalog **nearly 100,000** structures and shares public polygon viewers, asking whether Miotti or the agents searched those indexes first.\n\nThat is the right skepticism for builders: **agent speed is useless if your retrieval step misses the national catalog**. A production pipeline would **mandate GIS cross-checks** against INAH and academic shapefiles **before** email, not only LLM literature search.\n\n## How this differs from lab archaeology ML\n\nRecent Maya lidar science includes peer-reviewed **city-scale** finds and **population estimates** Miotti cites at the bottom of his post. Those papers used **domain teams**, **years** of validation, and **institutional partnerships.\n\nMiotti's experiment is closer to **citizen acceleration**: a **naive outsider** plus **compute** plus **polite reporting**. The lesson for AI teams is **breadth**: agents are not only for **IDEs** and **Kubernetes YAML**—they chain **search, vision, translation, and bureaucratic formatting** on **public datasets** anyone can download.\n\nCompare to [Google and Janelia's fruit-fly connectome work](https://explainx.ai/blog/google-fruit-fly-brain-connectome-ai-2026): institutional science still wins on **proof**, but **individuals** can now initiate **credible tickets** in days.\n\n## Replicating the pattern (without heritage harm)\n\nIf you adapt this workflow for **other geospatial science**:\n\n1. Start from **licensed or public** lidar or satellite products with clear citation.\n2. Log **every agent pass** and keep humans on**send/no-send** for government mail.\n3. Cross-check discoveries against **authoritative registries** before claiming novelty.\n4. Withhold **precise coordinates** publicly when law or stewardship requires it.\n5. Treat model **reconstructions** as illustrations, not evidence.\n\nFor general agent security when tools browse untrusted pages, pair human review with practices from [Claude Code prompt-injection reminders](https://explainx.ai/blog/claude-code-hidden-ip-reminder-conceal-instruction-prompt-injection-november-2026) and our [agent skills production pack](https://explainx.ai/blog/addy-osmani-agent-skills-production-pack-github-trending-2026) guidance.\n\n## What people are asking\n\n| Question | Practical answer | \n|---|---|\n| Can I discover ruins with ChatGPT alone? | You still need **geospatial data** ,**QC** , and**institutional reporting** —models coordinate text, not lasers. | \n| Is Miotti an archaeologist? | He states he is **not** ; treat structure IDs as**hypotheses** . | \n| Did INAH confirm a new site? | They said **none registered** at the point—field science may still follow. | \n| Was a custom model trained? | **No** , per his account—**vision over renders** with agent labor. | \n\n## Prior science Miotti cites—and why context matters\n\nMiotti's footer links peer-reviewed **lidar archaeology** threads readers should not skip:\n\n- **Cook et al. 2013** on NASA**G-LiHT** instrumentation—the hardware lineage behind many airborne strips.\n- **Golden et al. 2016** on reusing environmental lidar for archaeology.\n- **Auld-Thomas et al. 2024** on a**Maya city** found via lidar surveys at institutional scale.\n- **Estrada-Belli et al. 2025** on**population estimates** from lowland lidar.\n- **Šprajc 2026** on possible**ancient marketplaces** detected in lidar.\n\nThose papers establish that **machines finding rectangles under trees** is not new. Miotti's twist is **agent labor at hobbyist speed**: one person coordinating **48 parallel visual reviews**, literature checks, and **bilingual bureaucracy** without a grant consortium.\n\nIf you work in **computer vision**, treat this as **human-in-the-loop at scale**, not a replacement for **INAH archaeologists** who hold excavation authority.\n\nComputer vision style review of geospatial lidar strips for structure detection\n\n## Compute, cost, and honesty about \"48 agents\"\n\nMiotti writes that **48 agents** reviewed lidar tiles overnight like **patient archaeologists**. In practice that means **dozens of parallel vision-heavy model calls** over rendered strips—not a single cheap embedding search. Budget planners should expect:\n\n- **Egress and storage** for lidar tiles if you mirror strips locally instead of streaming from agency portals.\n- **Vision token charges** if you use frontier multimodal APIs on thousands of PNGs.\n- **Human QC hours** the next morning—Miotti's diary shows he**iterated** the report when agents erred.\n\nThe story is still cheaper than chartering airborne lidar, but it is **not free compute**. Teams chasing [remote labor automation metrics](https://explainx.ai/blog/remote-labor-index-fable-5-2-automation-rate-scale-cais-2026) should log **dollars per square kilometer screened** when pitching science leads, not only romance about Bingham.\n\nWhen agents disagreed, Miotti kept **multiple model families** in the loop rather than trusting a single vendor verdict—a pattern that also shows up in enterprise eval harnesses discussed around [Bedrock AgentCore playbooks](https://explainx.ai/blog/amazon-bedrock-agentcore-evaluation-playbook-deepeval-autoeval-guide-2026).\n\n## A minimal replication recipe for other regions\n\nAdapt Miotti's pattern only where **law and licenses** allow:\n\n| Stage | Tooling | Human gate | \n|---|---|---|\n| Source data | Public lidar or satellite composites with citation | Verify license for commercial reuse | \n| Tiling | Render bare-earth RGB or hillshade tiles | Spot-check one tile manually | \n| Screening | Agent batches with a written rubric (plaza, platform, road) | Discard obvious geology | \n| Registry cross-check | Query national heritage GIS + academic shapefiles | **Mandatory** before publicity | \n| Reporting | Draft PDF in local language | Lawyer or local partner reviews send | \n| Publication | Blog without precise lootable coordinates | Wait for agency response | \n\nPair registry checks with the skepticism surfaced on Hacker News—**ks2048's** point about existing polygon maps is a **free test** your pipeline should automate on day one.\n\n## Ethics and hype guardrails\n\n- Do not treat **INAH's email** as a**Nature paper** .\n- Do not publish **lootable coordinates** to drive engagement.\n- Credit **public lidar programs** and**prior Maya lidar science** Miotti links.\n- Avoid claiming agents **replace** archaeologists—they**compress paperwork and search** , not trowels.\n\n## Related reading on explainx.ai\n\n*Timeline and images follow [Pietro Miotti's post](https://pietromiotti.com/latest/maya-site/?ref=explainx) as published; INAH's reply is shown there in Spanish.
