TerraCity
Operate the city from current reality.
TerraCity converts aerial imagery, reality meshes, municipal records, market signals, and field data into a city operating model: current objects, detected change, confidence, priorities, and action packets for government teams.
Observe

Decide
Act
Observe reality. Decide with proof. Act through existing systems.
Operating Model
A city operating model, grounded in reality.
TerraCity connects observation, record, decision, and action in one spatiotemporal model. Every object carries where, when, source, confidence, lineage, owner, and workflow state.
- Physical reality
- Imagery, mesh, elevation, geometry, condition, capture date.
- Institutional record
- Parcel, permit, declared area, assessment, transaction, owner.
- Operational state
- Match, discrepancy, confidence, priority, owner, workflow.
From Observation To Action
Close the loop from change to action.
A roof surface appears in the latest capture. TerraCity links it to parcel and permit context, compares records, scores priority, and moves the finding to the right team with proof attached.
Parcel, permit, declared area, owner, and prior captures linked.
Priority from mismatch, confidence, value impact, and appeal risk.
High-confidence findings move to action; uncertain cases go to review.
- Observed
- new roof surface
- Where
- parcel, building, capture date
- Record
- declared area, permits, history
- Route
- review packet or field check
Physical Reality Layer
The current state of the city.
TerraCity starts with what exists: buildings, roofs, roads, sidewalks, trees, public space, terrain, utilities, access, and visible infrastructure. Every object keeps its source, date, lineage, confidence, and change history.

City Ontology
Model the city as objects, events, and actions.
The physical surface becomes reusable operational logic: objects, attributes, relationships, records, forecasts, confidence, lineage, actions, and change through time.
- Geometry
- footprint, roof plane, height, volume, surface, boundary.
- Time
- capture date, change event, update cadence, forecast window.
- Records
- parcel, permit, declared area, assessment, listing, sale.
Fiscal Intelligence
Close gaps between reality and records.
Connect observed change to declared records, permits, assessments, transactions, listings, and neighborhood context so fiscal teams can prioritize high-value cases with proof intact.
- Observation
- source, capture date, geometry, confidence.
- Record
- declared area, permit history, assessment, owner notice.
- Delta
- measured mismatch, comparable evidence, review priority.
- Action
- clear, inspect, notify, update, appeal packet.
Operations
One operating picture for every agency.
Planning, cadastre, finance, public works, mobility, utilities, security, civil defense, environment, maintenance, and emergency response can act from the same measured view of the physical city.
Measured Inventory
A common object model for city work.
The first product is not a map of everything. It is a trusted model of observable assets, conditions, and changes, with uncertainty routed to review before it becomes action.
Buildings, floors, roofs, additions, pools, garages, sheds.
Sidewalks, curbs, pavement, surface condition, encroachment.
Trees, canopy, vegetation, water, impervious surfaces, drainage risk.
Declared area, taxable base, valuation signals, permit mismatch.
Access constraints, critical visible infrastructure, maintenance candidates.
Source, date, confidence, model version, prediction, and review state.
Decision Logic
Make every decision defensible.
Cities cannot run on black boxes. TerraCity preserves the source, date, geometry, confidence, lineage, and record context behind each object, discrepancy, priority score, valuation signal, and routed workflow.
Measure
Register imagery, orthos, elevation, point clouds, meshes, records, and market sources.
Reconcile
Convert observations into city objects, relationships, records, events, and context.
Prioritize
Score discrepancy, value impact, degradation, urgency, and review risk with evidence intact.
Route
Move high-confidence findings into agency workflows and route uncertainty to review.
System of Systems
Activate the systems that run the city.
TerraCity should not replace the city's GIS, portals, field tools, hubs, cadastral systems, utilities, or command centers. It keeps the physical reality layer current and pushes trusted objects, decisions, and workflows into the systems already used.
Imagery, meshes, parcels, permits, assessments, transactions, sensors.
Objects, events, confidence, lineage, decisions, and workflows.
GIS, portals, field apps, notices, utility workflows, command centers.
Scale
Built for full-city decisions.
The architecture accepts full-city imagery, elevation, mesh, vector, municipal record, market, and sensor inputs. Start with one city, prove the decision workflow, then repeat across regions and countries.

TerraCity
Build the operating model for physical city reality.
A current, evidence-backed model of what exists, what changed, what matters fiscally and operationally, where risk is accumulating, and which decision or agency action should follow.
