Collaborative GIS Application

This application enables real-time collaboration on drawing and analyzing areas on a map. Users can draw, view, and calculate the area of polygons in real-time, switch between map layers, and view other users’ actions as they draw.

Features

• Real-time polygon drawing on a map
• Satellite and regular map layer switching
• WebSocket-based updates for real-time collaboration
• Area calculation for polygons

Tech Stack

• Backend: Golang with Gorilla WebSocket and PostgreSQL
• Frontend: Leaflet.js, HTML, JavaScript
• Database: PostgreSQL with PostGIS for spatial data storage
• Docker for containerized setup
