§ Pillar 01 · Aqua
Survey. Cadastral truth.
Geospatial capture, GNSS processing, cadastral sheet management and parcel validation. Survey is the layer where geometry becomes evidence.
Features · grouped by pillar
Five pillars.
Five pillars.
One operating model.
Every Allodis feature lives inside one of five pillars. Each pillar is production-grade on its own. Together they form a single connected operating model for Caribbean land administration — Survey, Registry, Revenue, Identity, Platform.
✓
Geospatial capture
Ingest field GNSS submissions, total-station traverses, and remote-sensed extents directly from the surveyor's device.
GNSS · CSV · DXF✓
Parcel validation
Geometry quality, format support, topological consistency and ISO 19157 conformance — automated on every upload.
ISO 19157 · OGC SF✓
Cadastral sheets
Compose, version and publish official cadastral sheets. Track sheet status, edition number and audit lineage.
Versioned · Audited✓
Boundary reconciliation
Resolve discrepancies between historic deeds and current survey evidence with a structured reconciliation workflow.
Adjudication-ready✓
Coordinate transformations
WGS-84, regional grids, and historic Caribbean datums. Transformations are transparent, reversible and recorded.
EPSG · PROJ✓
Survey evidence trail
Every parcel update carries an audit trail back to its survey evidence — who, when, with what instrument, against what control.
Immutable · SignedGeometry● Valid
Topology● No errors
ISO 19157● Conformant

§ Pillar 02 · Violet
Registry. Title, transferred.
First registration, transfer, RRR management, adjudication and search. Registry is the layer where survey evidence becomes legal title.
✓
First registration
Structured workflow for bringing a parcel onto the title register for the first time — evidence, adjudication, decision.
Caveat · Adjudication✓
Transfer of title
Compose, validate and execute title transfers with structured decision recording and separation of duties.
Maker / Checker✓
RRR management
Rights, Restrictions and Responsibilities — mortgages, charges, easements, leases — composed against the parcel.
RRR · ISO 19152✓
Adjudication queue
Registrar work queue with case assignment, evidence tabs, structured decision recording and reason codes.
Case management✓
Certified search
Disclosure of title position with cryptographically signed evidence. Lookup by parcel, by person, by transaction.
Signed · Time-stamped✓
Separation of duties
Decisions require dual control. Submitter, reviewer and authoriser are tracked separately at every step.

§ Pillar 03 · Mango
Revenue. Leakage, closed.
Property tax, CAMA valuation, billing, payment and arrears. Revenue is the layer where every parcel event becomes a fiscal event.
✓
Property tax assessment
Annual assessment, supplementary assessments, exemptions and CIP overlays — composed against the live parcel.
Annual · Supplementary✓
CAMA valuation
Computer-Assisted Mass Appraisal with locality coefficients, property attributes and event-driven recalculation.
Mass appraisal✓
Event-driven reassessment
Boundary change, ownership change, building completion — each emits an event. Revenue cases are queued automatically.
Event-driven✓
Billing & invoicing
Generate, deliver and reconcile invoices for every taxpayer. Multi-channel: email, SMS, citizen portal, post.
Multi-channel✓
Payment processing
Caribbean bank rails, card, wallet and counter receipts — all reconciled to the parcel and the taxpayer.
Reconciled✓
Arrears management
Track aging, escalation, payment plans and recovery actions — with audit-grade evidence of every step.

§ Pillar 04 · Fuchsia
Identity. Verified once.
IDV, KYC/KYB, professional delegation, OIDC SSO and continuous monitoring. Identity is the layer where every actor is known.
✓
IDV verification
Government-grade identity verification — document, biometric, liveness — for citizens, professionals and operators.
eIDAS-grade✓
KYC / KYB
Individual and entity verification with continuous monitoring against sanctions, PEP and adverse-media sources.
Continuous✓
Professional delegation
Attorneys, surveyors, bankers and agents act on behalf of clients with explicit, time-bounded delegation.
POA · Bounded✓
OIDC SSO
Sign in with your national e-ID, professional body credentials or Allodis identity. Standards-first.
OIDC · SAML✓
ECCIRA alignment
Identity evidence configured to satisfy the September 2025 Eastern Caribbean compliance regime for CIP jurisdictions.
ECCIRA-ready✓
Audit-grade evidence
Every identity event — verification, delegation, sign-in — is recorded with evidence package and retention.

§ Pillar 05 · Lime
Platform. The foundation.
Observability, business rules, records management, feature flags and tenant provisioning. Platform is the layer that makes the other four operate.
✓
Observability
Logs, metrics and distributed traces from every pillar, every tenant — searchable in one place.
OpenTelemetry✓
Business rules engine
Jurisdiction-specific rules — fee schedules, exemptions, workflows — composed as declarative policy, not code.
Policy-as-code✓
Audit ledger
Immutable, cryptographically-signed record of every event. 7-year retention. Reason codes mandatory.
Immutable · 7yr✓
Service status
Public, real-time service health for every pillar — refreshed every 2 minutes via SignalR. Incident timelines included.
Real-time · Public✓
Tenant provisioning
One platform, many jurisdictions. Sovereign data residency, isolated billing and audit per tenant — multi-tenant by design.
Multi-tenant✓
Feature flags
Roll new capability to a single tenant, a region, or a pilot cohort. Phased rollout without code changes.

§ How they connect
One event. Five pillars in motion.
A single boundary update at the Survey desk flows automatically into the Registry, the Revenue queue, the Identity audit, and the Platform ledger. No batch jobs. No reconciliation. No paper.
§ Visual proof
Every capability, composable.
Each feature is a discrete capability, addressable through the Workspace, the Portal or the API. In production, these cards use real interface screenshots; here they are stylised mock-ups from /assets/screenshots.
● Survey

Common questions
What you can ask the platform.
And what it answers.
Do we have to adopt all five pillars at once?
+Can Allodis sit alongside an existing Trimble Landfolio deployment?
+How is the audit ledger different from a regular log?
+What does multi-tenant mean for our sovereignty?
+Is ECCIRA evidence retained for the full seven years?
+Can citizens self-serve without an Allodis account?
+What happens if the network is down?
