Introduction
Learn how to create powerful gravity-based heatmaps to visualize accessibility across your entire study area.
What You'll Learn
Heatmaps show accessibility levels across an entire area, not just from specific points. In this tutorial, you'll:
- Understand gravity-based accessibility modeling
- Configure heatmap parameters
- Interpret and style heatmap results
- Compare accessibility scenarios
Why Heatmaps?
While catchment areas answer "Where can I reach from here?", heatmaps answer "How accessible is every location in my study area?"
