Introduction 

This section explains how to create different types of maps, such as choropleths, heatmaps or thematic maps.

Tutorial(s) 

Maps  

• Create a map of Japan with standard map elements like map inset, grids, north arrow, scale bar and labels   Ujaval Gandhi: “Making a Map (QGIS3)”/”Een kaart maken (QGIS3)”  Language(s): English, Dutch   Chapters: overview of the task, get the data, procedure   EN: https://www.qgistutorials.com/en/docs/3/making_a_map.html   NL: https://www.qgistutorials.com/nl/docs/3/making_a_map.html  

• Styling data and creating maps: data styling, layer rending, blending modes, SVG marker, exporting, item properties panel, change font and legend, pdf export  Erik Meerburg (3D geoinformation research group): “Urbanism GIS Course 3: Styling data and creating maps”  Language(s): English  Time: 10m 31s  https://www.youtube.com/watch?v=L-TZbf__6yY  

QTiles  

Qtiles generates raster tiles from QGIS projects. 

• Create tiles from the global Natural Earth raster  Ujaval Gandhi: “Creating Basemaps with QTiles (QGIS3)”/”Basiskaarten maken met QTiles (QGIS3)”  Language(s): English, Dutch   Time: 12m 44s  Chapters: overview of the task, get the data, procedure   EN: https://www.qgistutorials.com/en/docs/creating_basemaps_with_qtiles.html   NL: https://www.qgistutorials.com/nl/docs/creating_basemaps_with_qtiles.html 

Choropleths  

Choropleths are statistical thematic maps that represent spatial variations of a quantity. 

• Difference between WMS and WFS and create choropleths   Mariëlle Geers-Plasmans (Geojuffie): “Choropleet voor beginners”  Language(s): Dutch  Time: 12m 44s  https://www.youtube.com/watch?v=6pT3aSGWnfA    

• Create bivariate choropleths   Mariëlle Geers-Plasmans (Geojuffie): “Bivariate choropleet”  Language(s): Dutch  Time: 13m 10s  https://www.youtube.com/watch?v=lR2vpwrwE00 

• Simple calculations with the Field Calculator and style a choropleth map   Hans van der Kwast: “Create a Choropleth Map in QGIS”  Language(s): English  Time: 11m 15s  Chapters: introduction (start-0:35), download open data (0:35-2:10), filter (2:10-2:40), GeoPackage (2:40-3:10), save project (3:10-3:30), calculate people per household (3:30-4:40), neutral color ramp (4:40-5:30), labels (5:30-7:00), print layout (7:00-7:40), add title (7:40-8:20), edit legend (8:20-9:20), add text (9:20-10:20), export (10:20-end)  https://www.youtube.com/watch?v=4Ay2tLGXhds 

Heatmaps 

Heatmaps are 2D graphical representations of data in which values are depicted by colors. 

• Create a heatmap to visualise regions with high density of crime   Ujaval Gandhi: “Creating Heatmaps (QGIS3)”/”Heatmaps maken (QGIS3)”  Language(s): English, Dutch   Chapters: overview of the task, get the data, procedure   EN: https://www.qgistutorials.com/en/docs/3/creating_heatmaps.html   NL: https://www.qgistutorials.com/nl/docs/3/creating_heatmaps.html  

• Create heatmaps and cluster points    Erik Meerburg (3D geoinformation research group): “Urbanism GIS Course 14: Heatmaps and clustering”  Language(s): English  Time: 12m 32s  Chapters: introduction (start-1:16), heatmaps (1:16-7:00), clustering (7:00-end)  https://www.youtube.com/watch?v=-Ocz2u90Sgg  

Hex maps 

Hex map are made of a hexagonal grid with QGIS. 

• Create a hex map   Erik Meerburg (3D geoinformation research group): “Urbanism GIS Course 15: Density using hex maps”  Language(s): English  Time: 7m 12s  Chapters: create a grid (start-0:21), using a hex grid (0:27-1:29), density map (1:29-end)  https://www.youtube.com/watch?v=ejCK2LbEhdA 

Thematic maps  

The following links show how to create a thematic map with QGIS. 

• Create a thematic map of the global population change between year 2000 and 2010   Ujaval Gandhi: “Basic Raster Styling and Analysis (QGIS3)”/”Basis opmaken en analyses van rasters (QGIS3)”  Language(s): English, Dutch   Chapters: overview of the task, get the data, procedure  EN: https://www.qgistutorials.com/en/docs/3/raster_styling_and_analysis.html  NL: https://www.qgistutorials.com/nl/docs/3/raster_styling_and_analysis.html  

Cartogram 

A cartogram shows the geometry of regions in a distorted way, which is based on the information of an alternate variable. 

• Create cartograms using the scale() function   Hans van der Kwast: “Create a Cartogram in QGIS 3.24 using the Scale Function and the Geometry Generator”  Language(s): English  Time: 12m 35s  https://www.youtube.com/watch?v=qxKD6wcFUcE  

> QGIS Installation

Do you still need to install QGIS? The QGIS installation and update section explains how to install QGIS on Windows and macOS.
