TerraNexa Maps is the geospatial division of THEAIPLUSPLUS LTD — not a subcontractor and not a separate company. We build and operate 3D WebGIS, digital twins, spatial data pipelines and spatio-temporal analytics systems for utilities, infrastructure operators, transport authorities and government programmes.
TerraNexa Maps (TerraNexa Intelligence) is the geospatial division of THEAIPLUSPLUS LTD, a company registered in England and Wales with company number 17397374.
Contracts, invoices and accountability sit with THEAIPLUSPLUS LTD, registered in England and Wales with company number 17397374 and registered office at 82a, James Carter Road, Mildenhall, United Kingdom, IP28 7DE. The team named in a bid is the team that delivers it.

The answer a pre-qualification questionnaire is looking for.
This is the same entity that signs and delivers our AI and software engineering work, so a bidder questionnaire that asks for group structure, ultimate parent or company registration number has one consistent answer.
Every capability below is in production somewhere in the portfolio further down this page.
Photoreal and schematic 3D scenes in the browser over real terrain, 3D tiles and live feeds. Cesium, deck.gl and MapLibre, with the interaction model built for operators rather than for demos.
PostgreSQL/PostGIS schema design, indexing and zero-downtime migrations; ETL and tiling for vector, raster and point-cloud data; reproducible scheduled analysis with monitored runs.
Sentinel and Landsat ingestion, cloud masking, band maths and derived indices; SAR where optical will not do; change detection over time-series stacks.
AIS, SCADA, IoT, telemetry and numerical weather feeds resolved onto one reconciled timeline and coordinate frame, so different sources can be reasoned about together.
Constrained-flow and graph models over networks — distribution grids, corridors, pipelines, transit lines — simulated forward with time as a first-class dimension.
Decision surfaces for control rooms and analysts: measured state, forecast state, exceptions, and a drill-down path from a network-wide view to a single asset.
Fusing legacy asset registers, spreadsheets and third-party APIs into one authoritative spatial model — usually the largest and least glamorous part of a real programme.
Containerised deployment, infrastructure-as-code, documentation and schema handover. Built to be operated by your team, not to keep you dependent on ours.
Not screenshots of past work — running deployments your technical evaluator can open right now. Each one is a different sector on the same spatio-temporal engine, which is why entering a new domain is modelling work rather than a platform rebuild.
Substation-to-home power flow across a complete radial distribution network over photoreal 3D Lower Manhattan, animating the daily load cycle with live consumption per building.
73 links · 55 customers
Live AIS vessel flows through the nine choke points that carry world trade, simulating corridor closure across a 72-hour horizon and pricing the reroute per vessel.
9 choke points · 72h horizon
Predictive cross-border cold chain monitoring across nine jurisdictions on a 48-hour horizon, scoring excursion risk before the shipment is lost rather than after.
9 jurisdictions · 48h horizon
A spatial index of 5G congestion built from subscriber demand and cell geometry, exposing where capacity is failing and where a new site would actually pay back.
National cell grid
Trajectory conflict detection in four dimensions — three of space and one of time — showing where separation is lost and how much of it a schedule change would recover.
4D separation model
Multi-modal transit network optimisation: where the network fails under load, and which service or frequency change buys the greatest reduction in journey time.
Multi-modal network
Propagates a climate event through an interdependent supply network to show which second- and third-order nodes fail, and when — the cascade, not just the flood.
Continental cascade
Satellite-derived crop stress and yield signal by region, from vegetation indices over time-series imagery rather than sampled ground observations.
Regional stress index
Hydraulic modelling of a national water distribution grid with leakage localisation — where the network is losing water, and which intervention recovers the most of it.
National grid model
Wholesale power market congestion by pricing node — where the grid constraint sits, what it costs, and how it moves across the trading day.
Nodal congestion map
Historical revenue backtesting for grid-scale battery storage against real ERCOT market data, showing what a given dispatch strategy would have earned, hour by hour.
Historical dispatch
Each system is a deployment of the same spatio-temporal engine with a different domain model: network topology, time-series model and decision surface. That is the architecture claim on this page, and the portfolio is the evidence for it.
The models a prime contractor or programme owner usually needs.
You hold the contract and the geospatial scope needs an execution team. We take the WebGIS, spatial database and pipeline modules against your specification, schedule and acceptance criteria, and report into your programme structure.
We join the bid as the technical partner and stay through execution: the method statement, the architecture, and the effort estimates that survive a clarification meeting — then the delivery of what we helped specify.
You are the utility, authority or operator and you need the system built. We scope, build, deploy and hand over, with your team involved from the first week so the handover is a formality rather than a project.
The same stack the eleven systems above are running on today.
Answered here so they do not become an email thread.
The questions evaluators ask first.
No. TerraNexa Maps is the geospatial division of THEAIPLUSPLUS LTD and trades under that name. It is not a separate legal entity and not a subcontractor, so there is one registered company behind the geospatial work: THEAIPLUSPLUS LTD, company number 17397374, registered in England and Wales.
Both are THEAIPLUSPLUS LTD, the registered company. The geospatial division works under that single contract, so there is one point of accountability for delivery rather than an agreement subcontracted onward.
THEAIPLUSPLUS LTD is registered in England and Wales with company number 17397374, registered office at 82a, James Carter Road, Mildenhall, United Kingdom, IP28 7DE. Both are published on this page, in the footer of every page of this site, and on every page of TerraNexa Maps.
They are real deployments, live at their own URLs, and you can open each one from this page. They are in-house products rather than client operations, and we say so — but the software, the spatial models and the interfaces are production work you can evaluate directly.
Yes. On subcontracted work packages we deliver under your client-facing brand or white-label where required, and report into your programme structure on your cadence.
You get source, database schemas, infrastructure-as-code and documentation, plus a supported transition period. Systems can be deployed on your infrastructure, including private or on-premises environments, so the platform does not have to live with us.
Yes, and that is unusual. The geospatial division sits inside an AI and software engineering company, so forecasting, computer vision over imagery, document extraction and agentic workflow automation can be delivered under the same contract as the GIS platform — THEAIPLUSPLUS LTD is the single counterparty for both.
Send the scope, the tender reference or just the problem. We will tell you honestly whether we are the right technical partner, and what we would need from you to price a work package.
