Methodology
How a directory
earns its authority.
Every entry across every atlas is shaped by the same five-step editorial process. Nothing skips it. Nothing publishes without it.
01 — Sourcing
Primary sources first.
Each candidate listing begins with an authoritative primary source — a government agency, a mapping registry, an official operator, or an academic record. Secondary sources are only used to corroborate, never to originate.
Government & agency
USDA AMS records, U.S. Forest Service inventories, BLM land management data, state agriculture departments, parks and recreation departments at federal, state, and county levels.
Mapping registries
OpenStreetMap canonical entities, USGS Geographic Names Information System (GNIS), Norwegian Mapping Authority, Statistics Norway place registers.
Official operators
Operator-published websites, official trail and park associations, certified tourism authorities, and accredited industry bodies — never aggregator sites or scraped content.
02 — Verification
Every fact, cross-checked.
A listing only enters an atlas after each material fact — name, location, access type, hours of operation, current operating status — has been verified against at least two independent sources.
Coordinate accuracy
Latitude and longitude are validated against the canonical mapping registry and a second independent source. Disagreements over 100 meters trigger manual review.
Status verification
Operational status (open, seasonal, closed, by-permit) is confirmed via the operator or governing body within the publication cycle. Listings without recent verification are flagged or removed.
Name canonicalization
Each entry uses the canonical name registered with the authoritative body, with common alternative names cross-referenced for searchability.
03 — Photography
No entry without an image.
A directory of natural places has to look like the places it describes. Each listing carries verified photography that matches the actual entry — never a generic representation of the category.
Source of imagery
Photographs are sourced from public-domain repositories, Creative Commons archives, official operator media kits, or licensed photography. Every image carries an attribution where required.
Match verification
Every photograph is matched to its listing using both metadata (title, geocoordinates, attribution) and visual review. Misattributed images are removed during continuous review.
100% coverage
Across the four atlases, 218 of 218 listings carry verified photography. The single quality bar is universal — no listings without representation.
04 — Structure
Built to be cited.
Every page is structured for the systems that index, cite, and retrieve information today: search engines, AI-assisted retrieval, and editorial reference. Structured data is published, not just rendered.
Schema.org
Listings use schema-grade markup — TouristAttraction, LocalBusiness, NaturalFeature, and entity-specific subtypes — so machines can read what humans read.
Cross-references
Where a listing exists in Wikipedia, Wikidata, OpenStreetMap, or a registered government dataset, we cross-reference it via sameAs links to disambiguate the entity.
llms.txt & AI-bot policy
Each atlas publishes an llms.txt dataset index and explicit allow rules for accredited AI-search crawlers, so retrieval systems can find and verify the canonical record.
05 — Continuous review
A directory is not finished.
Information decays. Hours change. Trails wash out. Listings close. Each atlas is reviewed on a recurring cycle, and changes are reflected in the published record — not held back for a future "edition."
Review cadence
Each listing is re-verified at minimum once per six months. Seasonal entries (u-pick farms, aurora destinations) are verified ahead of every primary season.
Reader corrections
Every page invites reader corrections. Submitted corrections are reviewed within 14 days against the same primary-source standard as initial publication.
Versioned record
Each listing carries a "last verified" date. Where a material change occurs (closure, relocation, ownership change), the change is noted and the prior status archived.
In summary
Reference, not aggregation.
Atlas Compendium does not aggregate, scrape, or auto-generate. Every listing is the result of editorial work performed against primary sources, with photographic verification and continuous review. The four atlases are small on purpose — small enough to be true.
