Hit ► START in the bottom-left corner to begin the audit playback.
Each press of start steps forward one field day, revealing where citizen audit teams recorded observations across Bengaluru—in the order they happened, from 10 JAN to 19 MAY.
You can also drag the timeline slider to jump straight to any day.
Use the colour chips in the bottom-right to toggle a valley on or off, so you can focus on the progress of the valley you're curious about:
SCORE, DAY and TEAMS at the top track overall progress as the audit plays out.
If this visualisation made you curious, it has already done its job.
Each dot represents a real-world observation collected in the field.
But how did those dots get there?
The observations were recorded using ODK (Open Data Kit), an open-source mobile application used for collecting field data.
A single observation can include:
But why record all of that together?
Bengaluru's landscape is shaped by five natural valleys that guide how rainwater flows through the city:
This visualisation contains observations collected from three of these valleys:
Why these three? What stories might they tell about Bengaluru's drainage network?
A location tells us where something happened.
A timestamp tells us when it happened.
Together, they transform a point on a map into an observation that can reveal patterns, monitor change, and help us understand how cities evolve over time.
Because I believe curiosity is one of the best ways to learn.
Most of us use geospatial technology every day without thinking about it. We navigate with maps, book cabs, track deliveries, and check the weather.
Behind those everyday experiences are ideas that are scientific, simple and beautiful.
This visualisation is an invitation to ask questions like:
Those questions are where geospatial science begins.
If this visualisation made you curious, it has done its job.
I'm exploring new ways to communicate geospatial science through interactive visualisations, open-source tools, and urban data.
If you're interested in my work, have ideas to share, or are looking for someone who works at the intersection of geospatial science, coding, and science communication, I'd be happy to connect.
