Credit: Youtube Channel “Statistics Canada” In this second part we tackle the most common, yet often misunderstood, join scenario in QGIS: one‑to‑many joins. These arise when a single attribute in the destination layer matches multiple features in the source table. Proper handling of this relationship is crucial for accurate data interpretation and downstream analysis. 1….
Credit: Youtube Channel “Statistics Canada” Attribute Joins in QGIS – Part 1: One‑to‑One The ability to combine attribute data from separate layers is a core feature of QGIS. An attribute join lets you enrich your geometry layer with fields that live in another table or layer, without touching the source files. In this first part we’ll…
Credit: Youtube Channel “Statistics Canada” QGIS Best Practices and Tips for Layer Management Proper layer management is the foundation of efficient, error‑free GIS workflows in QGIS. A well‑structured project not only keeps you organized but also improves performance, readability, and collaboration. The following guidelines give you a practical framework to structure, curate, and preserve your…

This post dives deeper into Rule-Based Rendering and Labeling in QGIS, two powerful tools that let you create rich, context-sensitive maps. Why…
Credit: Youtube Channel “Statistics Canada” “`html Vector Data Visualization Part 1: Symbology Styles Using QGIS Introduction Vector data visualization is central to geographic information system analysis. QGIS, as the most widely used open‑source desktop GIS, offers powerful styling options that let you turn raw attribute tables into insightful maps. This post focuses on the symbology…
Credit: Youtube Channel “Statistics Canada” Editing Fields and Attributes with QGIS Field Calculator QGIS provides a powerful, expression‑based Field Calculator that allows you to create new fields, update existing ones, and manipulate attribute data without leaving the user interface. This post covers everything you need to know to get started – from launching the tool…
Credit: Youtube Channel “Statistics Canada” When working with geographic data in QGIS, the ability to quickly isolate specific features based on their attribute values is essential for spatial analysis, map styling, and data quality checks. Attribute queries let you craft logical expressions that identify precisely the features you need, whether they belong to a particular…
Credit: Youtube Channel “Statistics Canada” Getting Started with Vector Layers in QGIS Vector layers allow you to work with geographic data represented by points, lines, or polygons. In QGIS you can create new vector layers from scratch or by importing data from a file. The following guide walks you through the most common methods for…
Credit: Youtube Channel “Statistics Canada” Discovering Vector Data and Attributes in QGIS Vector layers are the backbone of most GIS projects, representing precise geographic features with points, lines, or polygons. While the spatial aspect makes them visually powerful, the real depth of analysis lies in the attribute data that accompanies each geometry. This guide walks…
