JestProject Overview
A focused utility application for converting mapping coordinates between DMS (Degrees, Minutes, Seconds) and Decimal Degrees formats.
The Problem
Manual conversion between Degrees, Minutes, Seconds (DMS) and Decimal Degrees (DD) is mathematically tedious and highly prone to human error. For developers and geographers, the lack of a simple, integrated tool that can both calculate these values and instantly visualize them on a map creates a significant bottleneck in spatial data workflows.
The Solution
I built a React-based utility that automates the conversion logic with real-time feedback. The tool allows users to input coordinates in either format or simply click on an interactive map to generate data points instantly. By integrating mapping libraries with a responsive Tailwind CSS interface, I created a seamless bridge between raw mathematical data and spatial visualization.
The Impact & Learning
This project served as a deep dive into Test-Driven Development (TDD). Given that coordinate precision is critical, I used Jest to implement a robust testing suite for the conversion algorithms, ensuring mathematical accuracy across edge cases. I also learned to manage complex state synchronized with interactive map components, resulting in a high-utility, reliable tool for geographic data management.
