📌 Network Analysis using QGIS | Complete Beginner-to-Intermediate Guide

In this video, we explore Network Analysis using QGIS, a powerful GIS technique used to analyze movement, connectivity, accessibility, and spatial interactions across networks such as roads, railways, rivers, pipelines, and utility systems.

🔹 What you’ll learn in this video:

What is Network Analysis in GIS?

Types of networks: directed vs undirected, weighted vs unweighted

Preparing network data in QGIS

Using Shortest Path analysis (distance & time-based)

Service Area / Isochrone analysis (accessibility mapping)

Understanding nodes, edges, topology, and impedance

Real-world applications in transport planning, urban studies, disaster management, and logistics

🔹 Tools & Plugins Used:

QGIS Network Analysis tools

Road network shapefiles

Attribute-based cost functions (distance, travel time)

🔹 Who is this video for?

Geography & GIS students

Urban planners & transport researchers

Disaster management professionals

Anyone preparing for UG/PG GIS practicals, PhD research, or competitive exams

🔹 Applications Covered:

Shortest route between two locations

Emergency response planning

Accessibility to hospitals/schools

Transport & regional development studies
