I’m pleased to share the completion of a recent commercial engagement by UrbanSpectra in collaboration with the Cooks River Alliance: the Cooks River Catchment Map.

The Cooks River Catchment Map is a user-friendly interactive map, designed to maximise the visibility, accessibility and accountability of improvements in the Cooks River catchment.

This easy-to-use catchment map effectively creates a 24/7 planning and reporting mechanism, increasing visibility for the public and providing information, accountability and tracking for decision makers.

The Cooks River Alliance is a partnership between organisations in the Cooks River Catchment, including Bayside Council, Canterbury-Bankstown Council, Inner West Council, Strathfield Council and Sydney Water.

The map is published at ourbackyardriver.com.au, and includes a table displaying the status of projects taking place in the catchment.

UrbanSpectra is a studio building data-driven mapping and urban analysis software for cities with a vision, founded by Jake Coppinger. UrbanSpectra brings a digital-native approach to understanding and improving cities, with great respect for direct observation and community engagement.

The Map

Drawing on examples like the Los Angeles River Revitalization program, the Cooks River Catchment Map is designed to be a tool for the public and decision makers to understand and advocate for a healthier river.

The map was built by UrbanSpectra, however editorial control of what is displayed on the map (and ongoing updates) remains under the care of the Cooks River Alliance.

The Cooks River Alliance aims to address the complex environmental problems of the Cooks River Catchment. The river runs through some of the most heavily urbanised and industrialised areas in Australia, but much of the catchment takes in popular walking trails and cycle paths, parks and facilities and significant native flora and fauna.

The map enables users to quickly see all proposed, under construction or completed projects across the entire catchment at one click. The features on the map remain an ever-improving work in progress, with continued updates and additions by the Cooks River Alliance as new projects are completed or data becomes available.

If you have feedback on the map, the Cooks River Alliance would love to hear from you – please contact them at info@cooksriver.org.au.

Community Efforts

The condition of the river has improved considerably in recent years, in large part due to persistent efforts by local community groups and stakeholders.

The map pinpoints bushcare sites under the care of the well-known Mudcrabs, a local community group caring for the Cooks River, regularly restoring bushland and removing rubbish. The map highlights bushcare sites by the Wolli Creek Preservation Society, a wholly volunteer organisation caring for the bush since the 90s (which also saved the Wolli Creek Valley from the proposed surface M5 expressway along the Wolli Valley past Turrella). The map points to the Cooks River Paddle Trail, which assists canoe and kayak enthusiasts to explore the river – and whose volunteers have removed at least 1.2 tonnes of litter.

Showcasing the information and efforts of work by local community groups is a critical function of the map, which links to these organisations and helps users learn about nearby efforts they could join.

The map also visualises the extent of the sheet steel piling along the river, which has been a significant focus of the community and was extensively discussed at the recent forum hosted by the Cooks River Catchment Community Collective in November 2025.

Council Projects

There are lots of great projects happening in the Cooks River catchment, by a number of distinct councils and organisations. Varied projects include park upgrades, new boat ramps, new footpaths, cycleways and lighting improvements. All the data on the map is also displayed in a tabular format on the about page for easy stakeholder reference.

Engineering

UrbanSpectra undertook product and software development for the map, working closely with the Cooks River Alliance through regular check-ins and a structured evaluation of potential solutions and platforms before build. CRA staff tested the map and admin tools in blitz-review sessions, and the team kept a shared feedback register to prioritise fixes before launch.

A significant challenge in the initial brief was empowering non-technical Cooks River Alliance staff to create and continuously update map layers, including the ability to import data from external sources (such as council documents) which are typically published as non-georeferenced raster images.

UrbanSpectra developed an innovative solution to enable CRA staff to georeference maps in documents using a browser-based tool without any software installation required, integrating with the existing CRA data storage to load data into the map – all without the need for any technical geospatial or GIS expertise.

A map is only useful if it is accurate and up to date. Along with existing data held by the Alliance, the Cooks River Catchment Map enables CRA staff to ingest features directly from OpenStreetMap, as well as georeferencing documents as they become available and from their own and other sources. This enables up-to-date layers from community and government map contributors, such as proposed and under-construction cycling infrastructure. The flexibility of running queries on OpenStreetMap data supports unlimited flexibility for future features and layers.

The project was originally only required to investigate and evaluate options for a draft map solution and a beta version, however thanks to initial prototyping and the flexibility of the solution it has evolved into a functional production-ready map.

UrbanSpectra approached the project in an iterative manner, with early prototypes and spikes to align stakeholders amid a wide-open project brief to identify necessary functionality. UrbanSpectra assisted with branding and defining the scope of the project.

Initial prototypes leveraged familiar interfaces for the team like spreadsheets and Airtable before developing a more flexible custom backend – which takes non-technical users step-by-step through the process of georeferencing maps and adding data to the map. UrbanSpectra also delivered detailed technical and user training documentation.

From a technical perspective, Jake Coppinger led all aspects of the solution design and delivery, including:

• Product co-design and scoping with the Cooks River Alliance team
• Project management and delivery oversight, using an incremental approach with a rapidly improving deliverable and tight feedback loop.
• Full-stack software development, from the frontend design, serverless backend with authentication, hosting and ingestion of data from external sources.
• Graphic design
• Technical and user training documentation

The result is a reliable, easy-to-use (and easy-to-maintain) custom map built on industry-standard technologies, with comprehensive documentation and extensive flexibility for future feature development.

I’m pleased to share the completion of a recent commercial engagement with the Heart Foundation: the Community Walkability Map, a new interactive tool designed to help communities understand and advocate for more walkable, healthier neighbourhoods.

About the Project

The Heart Foundation has a longstanding commitment to environments that support heart health, physical activity, and healthy living. As part of this mission, they commissioned a user-friendly platform that visualises pedestrian access to everyday destinations – empowering residents, advocates, and planners alike to identify opportunities for improvement in the built environment.

The map allows users to drop a pin anywhere in Australia and visualise accessible destinations within 5, 10, 15, and 20-minute walk catchments. These walkability catchments are not based solely on distance – they account for real-world walking conditions including path connectivity, barriers such as highways, and signal timing delays.

This map is now a central feature of the Heart Foundation’s Community Walkability website, which also includes community checklists, fact sheets, planning guides, and a Supporters’ Toolkit for professionals in the built environment sector.

A Data-Driven Tool for Policy and Advocacy

A key innovation of this project is the integration of traffic signal delay-aware isochrone modelling – a methodology that highlights delays to people walking at crossings, often overlooked in conventional walking catchment calculations.

Built using open-source OpenStreetMap data, the tool translates complex urban transport data into an intuitive, map-based interface that supports both strategic communication and policy engagement.

From a technical perspective, I led all aspects of the solution design and delivery, including:

• Co-design and scoping with the Heart Foundation team
• Project management and delivery oversight, using an incremental approach with regular status updates
• Backend isochrone algorithm development, implementing signal delay estimation
• Geospatial data integration and transformation
• Serverless backend development
• Graphic design
• Frontend software engineering

The end result is a tool that blends open data, urban analytics, and visual storytelling to support healthier, more walkable communities.

Data Sources

The map’s core walkability modelling is based on OpenStreetMap (OSM) data. Where possible, users are encouraged to contribute updates to OSM or via the Mapbox contribution portal.

Additional datasets integrated under agreement with the Heart Foundation include:

• Street lighting data from Ausgrid and Citipower
• Tree canopy coverage from the NSW DPHI (CC BY 4.0)
• Traffic signal delay data from Better Intersections (ODbL licensed), supplemented with interpolation or estimated averages in data-sparse areas

Users can explore data attributions directly via the map interface and are welcome to contribute additional signal timing measurements here.

Reflections

It was a pleasure to work closely with Anna Gurnhill and the broader Heart Foundation team throughout this project. Their vision, clarity of purpose, and genuine commitment to creating healthier, more accessible communities made this a rewarding collaboration.

What’s Next?

If you have an interesting challenge in the urban analytics, planning or community consultation space and would like to collaborate – let’s chat.

You can also read more about my background, including my five years as a full-stack engineer at Atlassian, open source work and policy advocacy here. I’ll have more to share on a new commercial entity soon.

I’m looking to further explore the potential of traffic signal-aware isochrone analysis to quantify urban accessibility and support data-driven planning and placemaking initiatives.

I’m particularly interested in applying similar methodologies to cycling network analysis.

I retain ownership of the underlying IP developed in this project and am open to discussing its further application in other domains.
