WB Land Info Case Study

WB Land Info is a feature-rich mobile application designed to make land-related information and everyday document management more accessible for people in West Bengal. The app brings together land record services, land measurement tools, document utilities, and productivity features in a single, user-friendly interface.

The Bottleneck: Landowners, property buyers, and surveyors in West Bengal often faced friction when switching between disparate web portals and multiple tools for Khatian/Plot checks, land area calculations, document scanning, and file size reduction for online filings.

Target Audits: Researched end-user workflows across urban and rural West Bengal. Users required direct mobile access to Khatian & Plot lookups, Mouza map requests, regional unit area calculators (Katha, Bigha, Acre), and built-in utilities like OCR and target-size image compression.

Wireframing & Prototypes: Designed an intuitive dashboard organizing 9 essential modules: Khatian & Plot Search, Citizen Services Portal, Mouza Map Request, Land Classification, RS-LR Conversion, GPS Area Calculator, Document Scanner, and Daily Notebook.

Visual Design: Built a modern mobile experience with day/night modes, clear iconography, regional language support, and seamless Google AdMob integration (native, banner, and interstitial) compliant with user experience policies.

Engineering Logic: Engineered using Flutter and Dart with REST API integrations, Google Maps SDK for GPS walking/perimeter calculations, on-device OCR text extraction, image compression controls, and Google Mobile Ads SDK.

Core Engineering Challenge: Ensuring accurate GPS polygon perimeter calculations during field walks while maintaining battery efficiency, and keeping ad formats respectful of core document and calculator workflows.
