Every day we hear about floods, heat waves, and climate change.

Yet most people still cannot answer a simple question:

"What is happening where I live?"

Over the past several years, I have worked on public-sector GIS projects in Japan, designing products for disaster preparedness, urban planning, environmental visualization, and citizen participation.

What surprised me most was that people were rarely asking for GIS itself. They were asking for a better way to understand their own communities.

This talk shares how these projects gradually changed my perspective as a product designer. Rather than focusing only on maps, layers, or dashboards, I will explore how open geospatial technology can help people observe environmental change, understand local context, make informed decisions, and participate in shaping the future of the places they live.

I believe the next challenge for the FOSS4G community is not only making geospatial data open—but making spatial understanding accessible to everyone.
