Who it's for
Flood depth and extent for site selection, route alignment and asset screening — across roads, rail, energy, logistics and industrial land.
Free, with no login: browse the 100-year layer, check individual sites, and cite the figures in a feasibility note. Corridor screening, the specific return periods design work needs, and climate scenarios are paid tiers — the free tier is a single point on the 100-year event, rate-limited.
The problem
Flood screening tends to happen late — after a site is acquired or an alignment is fixed — when the remaining options are expensive engineering rather than a different location.
Publicly available hazard mapping in India is fragmented across states and agencies, and rarely at a resolution or in a format a design office can use directly.
Linear assets make this worse. A road or a line is only as available as its most exposed kilometre, and that kilometre is easy to miss on a site-by-site check.
In practice
Each one is a real workflow — who does it, the situation, the steps, and what comes back.
Twenty candidate parcels, and flood risk is not yet part of the shortlisting criteria because checking each one is slow.
What you get: Flood screening early enough to change which land gets bought.
GET /v1/point An alignment crosses several catchments and the exposure is not uniform along it.
What you get: A segment-level view of where the alignment is exposed — 12.8% of India’s mapped road network sits in the modeled floodplain.
GET /v1/point · POST /v1/portfolio Detailed hydraulic modelling is expensive. The question is where it is actually needed.
What you get: Detailed study budget spent where it changes the design, not spread evenly.
On request — 25/50/100/500-yr The design office needs the hazard layer visible alongside survey, cadastral and alignment data.
What you get: The hazard layer in view next to your own drawings, with exposure numbers for your boundary.
GET /v1/tiles · POST /v1/exposure Plants, depots, substations and warehouses were sited over decades under different assumptions.
What you get: A ranked resilience list across the estate, from one pass.
POST /v1/portfolio How you get it

A 30 m screening layer is not a design flood level. Use it to compare options and to decide where detailed hydraulic modelling is warranted — not as the basis for a structural design. In steep terrain the modeled depth is least reliable, and we flag those states explicitly.
We publish the limits next to the numbers. A risk map that hides its own weaknesses isn’t a public good.
Design work usually needs 25-, 50- or 100-year events and sometimes 2100 climate scenarios. All are available on request.
