Borewell Check

Ground Water Prospect Check — a native Android (Kotlin) app that auto-loads your location, queries ISRO's public Bhuvan-Bhujal (GWIS) groundwater prospects data, and gives you a farmer-friendly, decision-oriented answer.

🚫 Not affiliated with ISRO / NRSC. This is an independent community tool using publicly available government data. Always confirm with a licensed hydrogeologist before drilling a borewell.

Features

How It Works

1. Reverse-geocodes the coordinates using the GWIS searchlatlon.php API.
2. Resolves the Indian state via a bundled 34-state registry.
3. Fetches the groundwater prospects polygon via the NRSC proxy.cgi WMS GetFeatureInfo (layer gw:<STATE>_LGEOM).
4. Classifies the result (GOOD chances / MODERATE / POOR) + success probability and renders the decision banner and guidance.
