Maps do more than document space—they shape who is visible, prioritized, and excluded. Participatory mapping is often framed as a democratizing tool, giving communities the power to define their spaces, advocate for their needs, and counterbalance top-down spatial governance. Yet, its impact is far from straightforward. Who gets to participate? Whose knowledge is valued? Does participatory mapping shift power, or does it generate more data for existing decision-makers?
Even when participatory mapping is used to collect data more inclusively, it is only one part of the cartographic process. How data is interpreted, visualized, and shared introduces further ethical ambiguities. Who decides how community-generated data is represented, what is emphasized or omitted, and how it informs policy? Mapping is about participation and who controls the narrative that emerges from the map.
Whose Knowledge Counts?
Mapping tends to privilege “expert” data while sidelining local, Indigenous, and community knowledge. Scientific models and GIS technology often take precedence, while oral histories, cultural understandings of space, and lived experiences are treated as anecdotal.
This is especially evident in Indigenous land mapping, where governments demand scientific proof of land occupation, even though Indigenous spatial knowledge has been passed down for generations. If mapping is to serve justice, it must value multiple ways of knowing.
What Gets Mapped, What is Left Out?
Governments and institutions only map what aligns with their administrative, economic, and political priorities—land ownership records, taxable properties, formal infrastructure, and predefined risk zones. Communities that fall outside these categories—such as informal settlements, migrant populations, and unhoused groups—often remain unmapped or misrepresented. If an area is not included in official mapping systems, it is often not recognized in policy, meaning no government resources, legal protections, or climate adaptation funding.
Participatory mapping is often used to make marginalized communities visible, yet visibility is not always safe. For some groups, remaining off the map is a deliberate act of protection—a way to avoid surveillance, policing, eviction, or forced assimilation into state systems. The ethics of mapping must consider not only who is made visible but also who decides whether visibility is in their best interest. A just mapping practice requires acknowledging that exclusion from official maps is not always about being ignored—it can also be about resistance, autonomy, or survival.
Who Controls How Maps Are Used?
Even when communities contribute data, governments and institutions still decide how that data informs policy. Climate justice activists, for example, have used participatory mapping to document flood risks in underserved areas. However, if decision-makers continue to prioritize economic interests, the data may be ignored—or worse, used to justify displacement rather than protection.
True justice in mapping is not just about collecting data—it depends on whether communities have the power to act on that data and shape the policies that affect them.
Who Has the Tools to Map?
Participatory mapping assumes equal access to technology, the internet, and spatial literacy, but these resources are not evenly distributed. The communities most vulnerable to climate change, displacement, or environmental hazards often face economic barriers, infrastructural limitations, and systemic exclusion from digital tools and education. Limited access to reliable internet, a lack of familiarity with mapping technologies, and language or literacy barriers can all hinder meaningful participation. In some cases, distrust of institutional mapping efforts—stemming from histories of land dispossession, policing, or extractive research practices—also discourages engagement.
Without addressing these underlying disparities, participatory mapping risks reinforcing the same inequalities it seeks to challenge, privileging those with access to resources while leaving the most vulnerable voices unheard. If mapping is to be a tool for justice, it must be accessible and inclusive, not another barrier that reinforces privilege.
Climate justice activists and adaptation efforts have embraced participatory flood mapping to incorporate local knowledge into risk assessments. Some key projects include: FloodNet NYC, MapSwipe, Public Lab, and Ushahidi. While these tools attempt to correct biases in traditional flood maps, they also raise ethical questions, like who decides whether community data is incorporated into official policies. Do governments only accept participatory data when it aligns with existing priorities? Can these projects redistribute power, or do they simply create more data for centralized decision-makers?
Rethinking Participatory Mapping as a Justice-Oriented Practice
For participatory mapping to serve justice, it must do more than add new data to existing systems—it must challenge the structures that govern spatial knowledge.
- Challenging Dominant Ways of Seeing Space
Maps are often used to make land and communities legible for governance, investment, or control. However, justice-oriented mapping should question dominant spatial categories rather than reinforce them.
Can participatory mapping resist bureaucratic classifications rather than conform to them?
Instead of mapping climate risk as governments define it, what if communities mapped risk based on their own priorities— housing security, cultural sites, or informal economies?
- Contesting Power Over Decision-Making
Even when participatory mapping is framed as collaborative, power often remains with decision-makers.
Who controls how maps are interpreted, and whose priorities shape the response?
What mechanisms can ensure community-led mapping leads to community-led decision-making?
How can participatory mapping be embedded into long-term governance models, not just treated as a temporary research tool?
- Expanding Alternative Mapping Traditions
Justice-oriented mapping should avoid dominant cartographic methods and embrace alternative mapping traditions.
Counter-mapping movements challenge state and corporate control of spatial representation. Indigenous land reclamation mapping, for instance, resists colonial narratives by asserting traditional land occupation based on Indigenous knowledge.
Feminist & radical cartography reject rigid GIS models, using storytelling, lived experience, and embodied knowledge as valid mapping methods.
For participatory mapping to truly challenge inequality, it must prioritize local knowledge, shift decision-making power, and embrace alternative mapping traditions. Otherwise, it risks becoming just another tool for reinforcing existing power structures.
As digital mapping expands, we must ask:
Can participatory mapping be a tool for liberation, or will it remain a symbolic gesture within systems of control?
