Geographic Inquiry: Asking Questions of Where
Before ever opening software, a GIS analyst starts with a question. "Where" is not just a coordinate; it is a relationship.
- Concentration: Where is the phenomenon clustered?
- Boundary: Where does it change sharply vs. gradually?
- Uncertainty: Where is the data missing or biased?
- Verification: Where would you stand on the ground to prove it?
📖 Narrative Cartography
Analysis is only half the battle. To be a successful GIS professional, you must be able to communicate your findings. Storytelling with Maps is the art of weaving geographic data into a compelling narrative arc—complete with a hook, a conflict, and a resolution.
Maps are powerful persuasion tools because they look objective. A well-designed "StoryMap" can convince a policy maker to fund a project or ignore a problem. But a story is always a selection of facts. By choosing what to show (and what to hide) to make the narrative "cleaner," are we acting as scientists or as propagandists?
🎨 GIS as an Art: The Narrative Arc
Great maps, like great novels, have a narrative structure. You start with the Setup (Context), introduce Conflict (The Problem/Data), and end with Resolution (Call to Action). Designing this flow is an art form—using color, scale, and timing to guide the user's emotional journey through the data.
Step 1: The Context
Start by setting the scene. Where are we in the world?
Step 2: The Data
Layer on the evidence. What problem are we seeing?
Step 3: The Call to Action
What should the reader do next? How can we solve this?
🤝 Interdisciplinary GIS: Digital Humanities
Storytelling with maps has opened a new frontier in the Humanities. Historians now use "Deep Maps" to layer literature, census records, and old photographs onto a single place. Innovative Art History projects use GIS to map the social networks of Renaissance painters. This blends qualitative richness with spatial precision.
Summary of Big Ideas
- Driving Attention: Use bookmarks and pop-ups to guide the reader's eye.
- Multimedia Integration: A map is better when supported by photos, videos, and scientific text.
- Mobile-First Design: Ensure your StoryMap works on a phone as well as it does on a desktop.
- Ethical Storytelling: Always cite your data sources and avoid "lying" with maps through manipulation of scales.
