Maps have a quiet kind of power. A line on a map can establish a boundary, guide an investment, justify a road, define a protected area, support a land claim or make a place disappear from view.
For people working in government, development or conservation, maps can feel reassuring. They make a complicated landscape look understandable. They turn territories, rivers, forests, livelihoods and routes into something that can be viewed from a screen or discussed in a meeting room.
But a map is never simply a picture of the world.
Its an argument about the world.
GIS, are so interesting to me. Used well, they can be powerful tools for communities to document their territories, identify threats, plan their own priorities and communicate with institutions that tend to listen most closely to formal evidence. Used badly, they can become another technology for turning lived lands into extractable information.
Every map includes and excludes
The first thing we should remember about maps is that they always involve choices. Someone decides which features matter, what scale to use, where a boundary begins and ends, what names appear, which time period is treated as relevant and which layers remain invisible. Those choices may be necessary, but they are not neutral.
Consider a forest. A satellite image might show tree cover, elevation, a river system and the changing edge of a road. All of that can be useful. But it may not show the seasonal route that families use to reach grazing land, the place where women gather materials, the sites connected to ceremony, the fishing grounds that cannot be disturbed, the patch of forest being restored by a local community, or the area that is intentionally left without public documentation. A map designed only from a distance can make a landscape appear empty even when it is full of relationships, responsibilities and history.
This is one of the ways that Indigenous Peoples can be made invisible. A territory may be recognized on a customary map, in oral history and in everyday practice, yet appear as vacant state land or as a generic conservation zone in an official system. Once that simplification enters a database, it can travel surprisingly far. It may shape a concession, an environmental impact assessment, a park boundary, a carbon project or a policy debate—often without the affected community being at the table.
GIS cannot fix that by itself. But it can help challenge it when it is used as part of a community-led process.
Mapping with, not mapping of
The language here matters. There is a big difference between mapping a community and mapping with a community.
The first approach often starts with an outside institution’s question: where are the resources, what are the risks, how can this area be categorized, and what information do we need for our report? The second starts with the community’s own priorities: what do we want to document, what are we trying to protect, what evidence do we need, and what should remain private?
Community-led mapping is not a single method. It can include walking and discussing a territory, drawing maps together on paper, recording place names in local languages, using GPS points, comparing historical imagery, or building digital layers in GIS. The tools should follow the purpose, not the other way around. In some cases a detailed online map will be useful. In others, a paper map kept locally, a password-protected layer or a verbal record may be more appropriate.
The most important thing is that communities should retain control over the process and the resulting information. This includes deciding who participates, which local governance structures guide decisions, what the map is intended to achieve, and who is permitted to see or use it. It also means recognizing that no community is a single voice. Women, youth, elders, people with disabilities, mobile groups and people whose livelihoods are often overlooked may have different knowledge and different priorities. A map that only reflects the views of the most powerful local actors can reproduce exclusion at a smaller scale.
Participation takes time. It cannot be compressed into a single workshop because a project plan has a deadline.
GIS can make claims legible, but it should not define reality
There is a practical reason why mapping remains important. States, companies and international organizations routinely use maps to make decisions. When a community has its own documentation of a territory, patterns of use, sources of water, cultural sites or environmental change, it can be better equipped to challenge an inaccurate map or demand to be consulted. GIS can connect local observations with legal boundaries, land registries, public infrastructure, protected-area limits and remotely sensed information. It can help turn an ignored concern into evidence that is difficult to dismiss.
For example, a community facing a proposed infrastructure project may use mapping to show that the project overlaps with farms, seasonal movement routes, water sources or sites of cultural importance. A community monitoring deforestation may compare satellite imagery with observations from people who know the area and can explain what the image cannot: whether tree loss reflects a fire, a legal harvest, an outside incursion, a restoration effort or a shift in cultivation. A group seeking better services may map the distance to clinics, schools and water points, and then use that information to make a more specific case to local authorities.
These are not only technical exercises. They are exercises in asserting a right to be heard.
At the same time, we have to resist giving the digital map more authority than the people whose lives it represents. A mapped boundary is not automatically a settled boundary. A point marked as a cultural site is not an invitation for outsiders to visit. A land-use layer cannot capture every form of access, responsibility or shared governance. GIS can support a claim, but it should not be used to force a community’s relationship with a territory into categories that do not fit.
The map should listen as well as speak.
The risk of making sensitive knowledge visible
This is perhaps the most important caution. Better mapping is not always safer mapping. A detailed public map can expose locations that should remain confidential. It can make sacred places, medicinal resources, seasonal camps or customary routes visible to people who may seek to commercialize, control or damage them. In some contexts, maps of community members, homes or patterns of movement can create immediate security risks.
The assumption that all data should be open is particularly dangerous here. Transparency is valuable when it holds powerful actors accountable. It is not automatically valuable when it requires communities to disclose sensitive knowledge in order to prove that they belong on their own land.
Before any mapping begins, there should be a conversation about risk. What information is safe to share publicly? What is useful only for a community? What may be shared with a trusted legal adviser or government counterpart under clear conditions? Who has the right to approve a request for access? Can the community revise that decision later?
These questions are connected to Indigenous Data Sovereignty. They are also connected to Free, Prior and Informed Consent. Consent is not satisfied by asking people to participate in a mapping activity; it includes decisions about the use, storage, publication and future reuse of what is collected. Community members should understand not only what will appear on the screen in front of them, but where the data will go after the workshop is over.
Technology should build local capacity, not dependency
GIS can feel specialized and intimidating. There are licenses, devices, file formats, imagery providers and technical language that can make it seem like a tool reserved for experts. That should not be the case. With the right support, GIS can be made accessible through training that is relevant to local goals, software chosen for sustainability, materials in appropriate languages and real opportunities for young people and community members to build confidence through practice.
But capacity-building should not mean handing over a platform and hoping for the best. It means asking what infrastructure is realistic, whether internet access is reliable, who will have time to maintain the work, and what happens when a grant ends. A project that creates an impressive map but leaves no local ability to update, interpret or control it has not transferred much power.
The most durable approaches invest in people and institutions. They support local mapping teams, community protocols, data governance arrangements and links between technical skills and decision-making processes. They recognize that elders’ knowledge, youth involvement, language, customary governance and technical training all have a place. Technical expertise must serve the community authority rather than replacing it.
Mapping conservation differently
These issues are especially important in conservation. Conservation maps can identify areas of high biodiversity, designate protected areas, estimate carbon stocks and prioritize investments. Yet too often they begin from an image of nature as separate from people. This can erase the historical and ongoing roles that Indigenous Peoples and local communities play in caring for their territories.
When conservation treats a landscape as wilderness waiting to be secured, mapping can become part of exclusion. A new boundary may limit access to customary lands. A biodiversity hotspot may attract funding while the rights of its inhabitants are treated as an inconvenience. A carbon layer may become more valuable than the people who have protected the forest over generations.
There is another path. Mapping can support conservation that recognizes land rights, customary governance and local knowledge. It can document the pressures communities face from extraction, encroachment or climate change. It can help connect ecological monitoring with the livelihoods and cultural practices that make stewardship possible. It can show that a healthy territory is not an empty one.
The global biodiversity framework talks about effective and equitably governed conservation, including recognition and respect for Indigenous and traditional territories. Those words need to become real on the ground. Maps will be part of that work. The question is whether they will be used to draw people out of the landscape or to recognize the people who already belong to it.
For me, I think that GIS is a powerful language because institutions understand maps. Communities should have every opportunity to use that language when it helps them advance their priorities. But they should never be required to translate every part of their territory, knowledge and identity into a dataset in order to be believed.
The best map is not the one with the most layers. It is the one that helps a community say what needs to be said, protects what needs to be protected, and leaves the authority where it belongs.
