Agriculture GIS for Land Measurement & Farmer Profiling
Table of Contents
Project Overview
Developed a Mobile GIS application to manage farmer profiles and accurately calculate agricultural land area using Google Maps SDK and polygon mapping via GPS coordinate tracking. Integrated the mapping application within a broader Agri-Tech ecosystem, establishing data traceability to connect land owners directly with a separate commodity marketplace platform.

My Contribution
-
Ionic Legacy Code Adjustments: Updated the Gradle configuration for legacy Ionic-based code to ensure smooth application performance. This was done to analyze the old JavaScript code and use it as a functional reference.
-
Android Native Rewrite (Fresh Start): Redeveloped the application from scratch using Android Native, transitioning all critical functionality from Ionic to achieve maximum performance and stability.
-
API Integration: Connected all backend endpoints, including integrating farmer and land data forms and their state management.
-
Land Measurement Features: Implemented geotagging and land area calculation features using the Google Maps SDK, with precise coordinates from Google Play Services.
Technical Implementation
-
Core: 100% Kotlin-based with Clean Architecture and MVVM design patterns.
-
UI/UX: Uses XML (ConstraintLayout for complex layouts and LinearLayout for simple ones), and RecyclerView optimizations to prevent performance issues.
-
Network & Asynchronous: Relies on Retrofit2 for REST API integration and Kotlin Flow for asynchronous task handling.
-
Dependency Injection: Uses Koin for its lightweight, efficient, and robust nature for application scalability.
-
Geolocation & Mapping: Calculates land polygon area using the Google Maps SDK, and records precise coordinate movements using the Fused Location Provider.
