11 systems live · 1 shared engine Enterprise solutions

Enterprise geospatial systems, built to run.

We design, build and operate 3D WebGIS, digital-twin and spatial analytics systems for utilities, infrastructure operators, government programmes and enterprises. Every system in the portfolio below is deployed, so you can evaluate the work by opening it rather than reading about it — and the same small team that scopes your project writes it.

Why enterprises work with us

What you get that a staff-augmentation contract does not

Four things we can be held to, each of which is visible in the portfolio rather than asserted on this page.

  1. We ship running systems, not slideware

    Eleven products in this portfolio are deployed and openable by anyone you send the link to. That is the standard we are proposing to hold your project to: every claim on a status call is a URL your team can open.

  2. One engine, many domains

    Our products share one spatio-temporal engine, so the difference between them is the data model and the domain logic rather than the technology. That is why the effort of moving into your sector is mostly modelling work, not a platform rebuild.

  3. Senior engineers on the delivery path

    There is no layer between the people who scoped your work and the people writing it. Requirements, architecture and implementation stay with the same small team from kick-off to handover.

  4. Built to be handed over

    Documented schemas, migration scripts, infrastructure-as-code and reproducible deploys. If you require the option to take the system in-house after go-live, we build for that from the first sprint rather than retrofitting it.

Core technical capabilities

What we build

Three offerings, in the order a programme meets them: build the interface, model the data underneath it, and keep the data current.

Build

Interactive 3D WebGIS prototypes and dashboards

Photoreal and schematic 3D scenes, operational dashboards and analyst tools that run in the browser with no install. We can put a defensible prototype in front of a client in weeks to de-risk a bid, then harden the same codebase into the delivered system.

  • Cesium, deck.gl and MapLibre scenes over real terrain and 3D tiles
  • Operational dashboards, time scrubbers and scenario controls
  • Prototype-to-production on one codebase, not a throwaway demo
Model

Spatial database management and analysis pipelines

PostGIS schemas, ETL, tiling and scheduled analysis. Geospatial systems fail on data far more often than on rendering, so this is where we spend the effort the visuals do not advertise.

  • PostgreSQL/PostGIS schema design, indexing and migration tooling
  • ETL and tiling pipelines for vector, raster and point-cloud data
  • Reproducible scheduled analysis with monitored runs
Integrate

Remote sensing and spatial data integration

Satellite and aerial imagery, sensor feeds and third-party APIs brought onto one timeline so operators see current conditions instead of last month’s export.

  • Sentinel and Landsat ingestion, cloud masking and derived indices
  • Live feed integration: AIS, telemetry, IoT and weather
  • Fusion of disparate sources onto a single reconciled timeline
How a system gets built

The delivery path, from scope to handover

Four stages, and the same small team on all four. This is the sequence the portfolio was built through; on your programme the data model changes, the method does not.

  1. Scope

    We take the problem, the constraints and the deadline, and come back with the architecture, the data model and an effort estimate — written by the engineers who will do the work, not by a pre-sales layer.

  2. Prototype

    A running prototype on your real data, in front of your stakeholders early. It is the cheapest point at which to be wrong, and it is what de-risks the business case before the build budget is committed.

  3. Production

    The same codebase hardened rather than rewritten: schemas migrated and indexed, pipelines scheduled and monitored, performance measured instead of assumed.

  4. Handover

    Documented schemas, migration scripts, infrastructure-as-code and reproducible deploys, so your team can operate the system or take it in-house on the terms you asked for.

Operational picture

One live view of the whole estate

GEV GEV — God’s Eye View

One continuously updated operational picture of an entire site, network or portfolio, read as a single live 3D view.

Most programmes already hold the data that matters; it is simply split across a SCADA screen, a GIS file, a spreadsheet and someone’s inbox. GEV composites those layers into one scene that updates continuously rather than on export: the digital twin, the live telemetry, the sensor feeds and the asset register, resolved onto the same coordinates and the same clock.

Whole-network situational awareness in one view, rather than per-system screens

Technical stack

The infrastructure your system would land on

A technical evaluator should be able to scan this and know whether we fit your estate. If a tool you depend on is not listed, ask — this list is the stack we build on rather than a full inventory of everything the team has touched.

Electricity distribution

ClarityGrid

Watch electricity move from a transmission hub through substations, feeders and transformers to individual buildings — in photoreal 3D Lower Manhattan, with a time scrubber over the load cycle.

ClarityGrid is the clearest example of what we would build for a distribution utility or a network operator: a full radial topology modelled as a graph and rendered onto photoreal 3D Lower Manhattan, with power visibly flowing from a transmission hub down through substations, feeders and transformers to individual metered customers. Every building carries its own live consumption, aggregated upward from customer-class load shapes, and a time scrubber runs the whole network across the daily load cycle.
