Executive overview
Matlas is a proposed operating geography for the surface of Mars. It addresses a problem that scientific maps and coordinates do not solve alone: how people, institutions and machines might refer persistently to regions, working areas and a precise location over decades of settlement, without confusing a place with whoever owns it or the object presently occupying it. The associated book is Matlas: An Operational Map of Human Mars, by JB Bullock.
Matlas has three separable parts. MGRID supplies a stable, nested global area hierarchy. BAR (Binary Address Reference) divides each MGRID Click into Court and Cell positions and expresses their identity as exact integers and canonical machine messages. Triplet / M3B is a proposed three-word human interface layered over that numerical identity. Scientific latitude and longitude remain authoritative measurements beneath these civil operating labels; locally chosen names, roads, property systems and governmental boundaries remain independent overlays above them.
This paper describes the architecture and ratified design decisions, not a completed globally certified geodetic system, production Triplet dictionary or independently accredited normative release. MRR-1 physical-reference authentication and genuine CSPICE parity, external BAR geodetic checks, and MB3-EN1 vocabulary compilation remain outstanding.
1. The hierarchy that Matlas adds
The canonical MGRID identifier is MGRID:1:MARS. It progresses from Quad → Zand → Province → Sector → Tile → Click. Four regular latitude Belts, each partitioned into six longitude columns, and two polar Quads give 26 Quads. Twenty-four 15° longitude Zones cross 24 regular Bands, producing 576 regular Zands; 24 Zone wedges in each polar cap add 48 more. The total is 624 Zands.
Regular Zands subdivide by fixed grids, whereas the polar hierarchy varies eastward branching with latitude and the actual containing parent. It does not pretend that longitude lines are equally spaced at the poles. The approved mathematical ownership rules give exact edge destinations: longitude boundaries belong to the eastward child, nonapex latitude boundaries to the poleward child, and each pole to a unique apex lineage. The equator is assigned to the northern hemisphere. These are design rules for deterministic partitioning, not empirical land claims.
The present mathematical MGRID partition contains 193,557,552 Clicks. A Click carries a canonical zero-based global ordinal whose 28-bit representation is used by BAR. Click ordinals come from a specific recursive walk of the actual hierarchy; they are not a simple flattening of latitude and longitude or a rectangular substitute for the polar geometry. The detailed reference is the author-ratified MGRID-1-MARS.md, and the book's MGRID chapters and Appendix E explain its use and limits.
2. BAR: the machine-address layer
MGRID stops at Click. BAR subdivides each Click into 16 × 16 Courts, and each Court into 16 × 16 Cells, making 65,536 Cell positions per Click. Court and Cell row and column indices are zero-based (0–15). Rows progress equatorward to poleward, columns west to east, following the parent Click's angular geometry even near the poles.
The exact integer design is:
CourtCode = (CourtRow << 4) | CourtCol
CellCode = (CellRow << 4) | CellCol
Court36 = (Click28 << 8) | CourtCode
Cell44 = (Click28 << 16) | (CourtCode << 8) | CellCode
A fixed-width Click28, Court36 or Cell44 is an address payload, with reserved values rejected. Their compact wire representations have distinct kind tags and use 4, 5 or 6 bytes. The machine transport BAR-JSON:1 adds explicit world, MGRID version, reference realisation and wire identity: the bare tagged frame is not, by itself, a globally complete context-aware location record. Mathematical capacity is 12,684,987,727,872 Cells; that is a count of possible address positions, not surveyed assets, inhabited plots or generated word triplets.
Exact angular boundaries identify an area in the stipulated MRR-1 reference. They are not a promise of surveyed ground accuracy, terrain elevation, centimetre guidance or valid conversion from an arbitrary spacecraft coordinate system. Those require separately verified reference transformations.
3. Triplet: a proposed human interface, not the machine record
Triplet / M3B proposes a human-friendly three-token way to communicate a BAR location while keeping the numerical BAR Cell identity canonical. The conceptual structure separates lexical functions across W1, W2 and W3 and uses semantic families and safety constraints as aids to detect mistakes in spoken or transcribed addresses. A vocabulary profile, such as the proposed MB3-EN1 US-English profile, would need a release-specific word inventory, encoding/decoding rules, exclusivity, pronunciation/familiarity checks, and independent safety testing.
Those outstanding tasks are substantial. Neither the book nor this paper claims that a globally complete reversible Triplet dictionary, allocation ledger, final speech-safety proof or production decoder is already issued. A human label cannot silently redefine the underlying Cell44 identity, and unapproved candidate words must not be treated as a usable public address service.
4. How layers interoperate
A typical conceptual workflow is measured planetary position → declared Mars reference → MGRID containing Click → BAR Court/Cell identity → optional Triplet presentation. The transformation at each boundary is explicit. Existing scientific maps, IAU-recognized feature names, geological/hazard datasets, future utility plans, rights and governance overlays remain distinct. A named crater does not become an MGRID Quad; an MGRID Cell does not confer ownership; and a BAR address does not uniquely identify a movable person or object.
This distinction makes Matlas an operating layer, not a replacement for maps or settlement choices. The book proposes ten design requirements (MR1–MR10) spanning reference anchoring, total surface coverage, nesting, persistence, neutrality, overlays, operational utility, human legibility, machine determinism and openness. Those are design goals, not proof that every imaginable future use case has passed an operational trial.
5. What has been tested—and what has not
The source technical checkpoint records author ratification of MGRID hierarchy decisions I1-A–I1-C and machine decisions R1–R5. Local numerical evidence includes exact polar-branch calculations, checkpoint regression suites, and 4,601 matching Python/JavaScript local comparisons in the cited T3.2g scope. The private handoff's receiving audit also executed 26 BAR machine smoke checks successfully. These strengthen confidence in the stipulated mathematical/encoding model.
They do not establish independently verified physical Mars coordinates. Specifically, the original NAIF pck00011.tpc source bytes and their hash have not been authenticated in the handoff, a genuine N0067+ CSPICE pxform comparison remains unexecuted, and third-party gold vectors are not furnished as independent certification. Triplet lexical safety and end-to-end language allocation remain in development. The proposed MRR-1 frame realisation is consequently a technical hold, not an externally authenticated datum release.
6. Release scope, versions and provenance
Matlas can publish a detailed, inspectable architecture while separately gating engineering profiles. The MGRID/BAR mathematical definitions, candidate code, human language proposal and physical-coordinate realisation should have different version and certification records. Any future redefinition of a previously issued cell's meaning must be deliberate and versioned, never a silent correction. Local labels and future Martian administrative choices must be allowed to change without rewriting canonical geometric identities.
A prior MGRID:1:MARS v1.0 Zenodo publication is reported in the private handoff as DOI 10.5281/zenodo.22695710 (10 September 2026). Its remote record and deposited bytes have not yet been independently reconciled in this publication-preparation stage. This paper does not mint a new MGRID normative DOI or imply the earlier deposit certifies BAR, MRR-1 or Triplet.
7. Publication and rights boundary
The separately copyrighted book Matlas: An Operational Map of Human Mars and its original illustrations remain all rights reserved, despite free web reading. This informative companion's original author text is approved for CC BY 4.0 upon its separately authorized public issue. Original code, author-owned datasets and third-party assets have different file-level licence conditions and are not automatically included in this paper.
In one sentence: Matlas proposes a persistent Mars-wide geography, a precise numeric place address beneath it, and a possible human word interface above it—with explicit boundaries between mathematical definitions, physical verification and unfinished lexical implementation.
