Application of Geospatial Techniques for visualization and analysis to interpret Geo-Coded lmages to enhance watershed Development Outcomes.

Ministry of Rural Development · Disaster Management · Software

The satellite half is free, easy and genuinely evidential, but this is a research proposal with a missing scope table and no geo-tagged photo corpus, so you would be defining the deliverable yourself and hoping the panel reads it your way.

What it actually is

Government watershed projects build check dams, ponds and plantations, and field staff photograph them with GPS tags, but those photos are only ever filed as proof rather than analysed. The ask is a way to combine those geo-tagged photographs with satellite imagery to actually assess whether the interventions worked. The stated satellite source is the department's own SRISHTI-DRISHTI platform at 30 metre resolution.

What to build

A watershed monitoring workbench that plots geo-coded field photographs onto watershed boundaries alongside 30 m satellite rasters, derives the thematic layers the description names — land use and land cover, drainage network, vegetation status, water bodies, soil moisture — computes before-and-after change detection around each intervention site over the project period, links each geo-tagged photograph to the pixel neighbourhood it was taken in so a planner sees the ground photograph and the spectral trend together, and produces the map products the statement asks for plus a per-intervention outcome assessment a district officer can act on.

Smallest thing that wins the room

Pick a check dam site, show its geo-tagged field photograph beside the NDVI and water-extent trend for that catchment across three years, and have the improvement visible in the curve rather than asserted.

How crowded this one gets

A guess, projected from the 2025 statements — the last year where both the submission counts and the winners were published.

A normal-sized field. Your idea has to be good, not miraculous.

Why: central ministry statements sat below the average.

This is a guess, not a fact

Nobody has published 2026’s numbers yet. This is an analysed estimate from last year’s pattern, so please do not take it as the truth — check the live counter on the SIH portal before you decide anything. The range covers the middle half of likely outcomes, so one statement in two lands outside it. Entry closes at 500 ideas per statement, so no range goes past that — a statement that reaches the cap fills and shuts rather than drawing an unlimited crowd. The model reads only three things a team can see before choosing — software or hardware, the theme, and what kind of body posted it — and those explain about a quarter of the variation in last year’s field sizes (R² 0.25 on held-out statements). Trust the band more than the number, and the ordering more than either. It cannot see how good your idea is, which is the part that actually decides it.

The scores

The number is the shorthand. The line under it is the reason.
