Demonstration
Explore a live city model.
See how TwinGov connects geography, public data and decision intelligence in one environment: the model, a worked question with its evidence, and the document that comes out at the end.
Public model
A public demonstration model is not published yet. Rather than point you at a placeholder, we run the walkthrough live on a model built from sources relevant to your organization, which is more useful anyway. The interface below is the real product concept, drawn rather than screenshotted, on invented geometry.
What a walkthrough covers
Three artefacts, in the order a decision uses them.
The coverage view sets recognised problems against the projects that address them. An area with a documented, funded project reads differently from an area where the institution has written down a problem and nothing has been programmed against it.
- Documented project in place
- Recognised problem, no funded project
- Existing facilities
- Candidate site
The view measures whether a project exists and how far it has got. It does not judge whether the institution was right to prioritise it.
02 / A worked question
Question
What communities are more than a 15 minute walk from essential services?
Answer
Four areas fall outside every essential service catchment when access is computed over the street network. Two of them sit within 800 metres of a facility in a straight line, and are excluded by the rail corridor rather than by distance.
Evidence
- Catchments computed as walking isochrones over the connected street network.
- Two of the four areas are within straight-line range but have no crossing within the walking threshold.
- Combined resident population of the four areas is above the model median for an equivalent area.

ConfidenceModerate
The network and the service inventory are well covered. The population figure is a residential count and will understate or overstate depending on the time of day.
What the data does not cover
- Daytime population is not connected, so workers and visitors are outside this analysis.
- Informal crossings are absent from the network layer and may shorten two of the four cases in practice.
03 / What leaves the platform
Essential service access
Areas outside every 15 minute walking catchment, with the barriers that cause the exclusion.

Product interface concept throughout this page. The map geometry is invented and every figure is illustrative. TwinGov shows no data about a jurisdiction until that jurisdiction connects its own sources.
What could TwinGov reveal about your community?
Start with the data you already have. We can build an initial model from available public and institutional sources and show where TwinGov can create immediate decision value.
