Urban Atlas Nepal brings research on urban risk down to where people live: the ward, the municipality, the district. We're starting with Kathmandu Valley.
Our first application brings hazard and live air quality to every ward of Kathmandu Valley, in plain language, at the moment someone is choosing where to live.
It's still experimental and we're refining it. Right now you can explore the ward-level flood model; earthquake hazard is paused while we improve it.
How the data is builtNot a flood simulation. Six environmental indicators are scored and weighted into one flood hazard index for every ward.
The indicators follow the weighted-overlay method common in GIS flood susceptibility research, including studies of Kathmandu Valley.
Re-weight it yourselfResearch on flood, earthquake, and air quality risk in Nepal's cities already exists, but it sits in reports, agency portals, and papers that rarely reach the people deciding where to live, build, or invest.
We bring that data together, make it comparable ward by ward, and put it where anyone can use it.
Gather
Hazard studies, government datasets, and open environmental data, wherever they already exist.
Structure
Clean it, reconcile it, and bring it down to the ward, so every place is described the same way.
Open it up
Publish it as plain-language maps anyone can read, and as open data anyone can reuse.
One live today, with more layers and applications being explored the same way.
Live now
Ward-level flood hazard and live air quality across Kathmandu Valley.
In exploration
Earthquake hazard returns once it's refined, with further layers added as data becomes available.
Built on the same atlas, one at a time.
