Building data for a resilient future

Colouring Ghana is a free, collaborative research platform that collects, visualises, and shares open spatial data on Ghana's buildings, helping communities, government, and researchers make better decisions about our built environment.

What is Colouring Ghana?

Colouring Ghana is a research-led, free public resource providing open spatial data on Ghana's buildings and natural environment, built collectively by and for academia, communities, government, industry, and the third sector.

The platform enables individuals, communities, researchers, planners, and government agencies to collaboratively capture and share information about Ghana's buildings, from basic location and land use data to structural characteristics, age, energy use, and disaster vulnerability.

All data contributed to Colouring Ghana is released as open data under the Open Database Licence (ODbL), making it freely available for research, planning, policy-making, and education. No special skills are required to contribute. Anyone with local building knowledge can help fill in the map.

The project aims to build a rich, granular, and continuously updated national database of building attribute data to support evidence-based urban planning, climate adaptation, infrastructure investment, and disaster risk reduction across Ghana.

🏛️ Host Institution

Department of Geomatic Engineering, Kwame Nkrumah University of Science and Technology (KNUST), Kumasi, Ghana.

🌍 Global Network

Colouring Ghana is one of many national platforms within the Colouring Cities Research Programme, which includes Colouring London, Colouring Dresden, Colouring Australia, and more.

📖 Open Data

All building data is free to use, share, and adapt under the Open Database Licence (ODbL). No registration required to view the data.

🔬 Research Focus

Urban resilience, climate adaptation, disaster risk reduction, sustainable development, and national spatial data infrastructure for Ghana.

What data do we collect?

The platform captures 12 categories of building attribute data, colour-coded by theme and collaboratively filled in by contributors across Ghana.

Location Geographic coordinates, address, administrative unit, and references linking each building to maps and spatial data.
Land Use Current and historical land use — residential, commercial, institutional, agricultural, industrial, mixed-use, and more.
Form & Size Building type, number of floors, footprint dimensions, total floor area, and morphological form classification.
Construction & Design Materials, structural system, roof type, cladding, architectural style, and key construction details.
Age & History Construction date, decade, any significant modifications, and historical significance or heritage listing status.
Planning & Conservation Planning designations, conservation area, listed status, ownership, building condition, and regulatory context.
Retrofit & Condition Energy retrofit works undertaken, structural condition, and maintenance status.
Energy Performance & Systems Energy rating, heating/cooling systems, renewable energy sources, and performance data for Ghana's climate zones.
Green/Water Infrastructure Trees, permeable paving, rainwater harvesting, drainage infrastructure, and natural environment context.
Urban Infrastructure Context Proximity to roads, utilities, public transport and neighbourhood connectivity.
Disaster Management Flood risk zones, fire history, structural vulnerability, and resilience features critical for Ghana's hazard landscape.
Community Community importance scores, neighbourhood character, social or cultural importance, and resident-contributed knowledge.

The colour scheme mirrors the Colouring Cities Research Programme's shared framework. Each category can be explored independently on the platform.

How can you contribute?

There are many ways to help — whether you're on the ground, at a desk, or at a university. Every data point counts.

01

Register an Account

Create a free account on the Colouring Ghana platform. Registration only requires a username and password — no personal information is required.

02

Find a Building

Use the interactive map to navigate to any building in Ghana. You can search by place name or postcode, or simply zoom into your neighbourhood.

03

Add or Verify Data

Click a building to see what data has already been captured. Fill in missing fields or verify information you know to be correct.

04

Survey Your Area

Go for a walk in your neighbourhood and note building characteristics — construction type, number of storeys, approximate age — then add them to the map.

05

Share Your Knowledge

Have archival records, local history knowledge, or professional expertise in urban planning, architecture, or engineering? Your specialised knowledge is invaluable.

06

Organise a Mapathon

Bring together students, community groups, or colleagues for a collaborative mapping session. We can provide training materials and support for group events.

Why does this matter?

Ghana's rapid urbanisation demands better building data. Without it, planning decisions are made in the dark. Colouring Ghana changes that.

🌡️

Climate Adaptation

Understanding the age, materials, and energy performance of Ghana's building stock helps identify where retrofit interventions are most needed as climate pressures intensify.

⚠️

Disaster Risk Reduction

Detailed data on building construction type, condition, and location enables better assessment of vulnerability to floods, earthquakes, and other hazards common in Ghana.

🏙️

Urban Planning

Planners, municipal authorities, and government agencies gain access to granular, up-to-date data to support infrastructure investment decisions and spatial development plans.

🎓

Academic Research

The open dataset supports research in urban studies, architecture, civil engineering, geography, environmental science, and development studies across Ghanaian universities.

🌍

National Data Infrastructure

Colouring Ghana contributes to Ghana's national spatial data infrastructure, filling critical gaps in building attribute data not captured by existing national datasets.

🤝

Community Empowerment

Citizens gain agency over the data that describes their neighbourhoods. Communities can use the platform's open data to advocate for better services and infrastructure.
