QGIS is open-source geographic mapping software that lets do things like plot long/lat coordinates from a csv file or visualize other geographic data such as population density. It supports a vast number of map projections and can convert between them. This post will explain how to set-up a new QGIS project and use some of its basic features.
Installation
You can download the latest version of QGIS here (windows/mac/linux): Download QGIS
You’ll also need some basic map data that you can get from a variety of online sources. I recommend this one: Natural Earth » Downloads - Free vector and raster map data at 1:10m, 1:50m, and 1:110m scales
I’ll be using the following files for this tutorial:
Download these files, unzip them, and put them somewhere you can find them later.
Duplicate Geo Lines Package
One problem with the ne_10m_geographic_lines package is it puts the equator, tropics, polar circles, and international date line all together in the same shapes file.
- Make a copy of the
ne_10m_geographic_linesdirectory in your OS file system - Name one
ne_10m_equatorand the otherne_10m_tropics
- Rename both the directories and files, keeping the file extensions unchanged
Setting Up a New Project
After launching QGIS and creating a new project, you’ll have a totally blank screen.
The first thing to do is import vector data of the landmasses. From the menu choose Layer > Add Layer > New Vector Layer...
click the ... to select the file to load and navigate to ne_10m_land/ne_10m_land.shp. Default settings are fine, click OK.
The landmasses are now visible as a Mercator projection.
Add vector layers for ne_10m_equator.shp, ne_10m_tropics.shp, ne_10m_graticules_15.shp as well using default settings.
The layers are now visible in the project.
Clean-up Equator & Tropics Lines
Now we’re going to delete the extra content from the equator and tropics layers. Right-click the tropics layer and choose “Open Attribute Table”
First enable editing by clicking “Toggle editing mode”.
Now select the rows to be deleted and click “Delete selected features”. Then click the toggle editing button again to turn it back off and choose to save when prompted.
Repeat for the equator layer, deleting all the rows except for the equator one.
Make pretty
Now let’s take a minute to make things look better. The background is white by default. To change it go to Project > Properties... > General > Background Color. Set the color to #90a0c0 for a pale blue (or whatever you’d like instead).
In the Layers window on the lower-left, double click the ne_10m_land layer to bring up the properties window. Change the color to #b9c3d9.
Double-click the ne_10m_equator layer. Change the color to #ff8000, the width to 3 points, and opacity to 65%.
Double-click the ne_10m_tropics layer. Change the color to #ffd501, the width to 2 points, and opacity to 65%.
Double-click the ne_10m_graticules_15 layer. Change the color to #505050, the width to 0.5 points, and opacity to 50%.
Now it’s looking a bit more presentable.
Change Map Projection
Now to change the map projection to Azimuthal Equidistant. Click the button in the very lower-right corner of the screen to choose the CRS (Coordinate Reference System).
In the filter type 102016 and select the ESRI:102016 - North_Pole_Azimuthal_Equidistant CRS (You may have to expand Projected and Azimuthal Equidistant). Then click OK.
Now we see the AE map projection.
Plot Sun Analemma from .csv data
Next, we’ll take a .csv file with latitude/longitude data for the 2024 solar analemma and plot it on the map. Here is the file we will use:
solar_analemma_2024.csv

Download the csv file above then from the Layer menu select Layer > Add Layer > Add Delimited Text Layer... and select the csv file on your local drive.
The default values should be okay, but verify that X field is set to Longitude and Y field to Latitude, and Geometry CRS is set to EPSG:4326 - WGS 84 (note that Latitude and Longitude come from the header of the csv). Click the Add button to close the dialog.
This adds a new sun_analemma_2024 layer and you’ll see the points plotted on the map. Next let’s stylize it a bit more.
First let’s display the date next to each marker. Double-click the sun_analemma_2024 layer to bring up the properties and go to the Labels section. From the dropdown at the top change it from No Labels to Single Labels. Then from the Value field below you choose which column from the csv data you want to use for the label. Pick Date from the dropdown.
Next we want to use a gradient to colorize the markers based on the suns angular velocity. Choose Symbology from the sidebar of the properties window and change the dropdown at the top from Single Symbol to Graduated. From the Value field below choose the csv column to use to determine the color, which should be set to Long/Hour. Set the Precision to 3 and select the 2 colors of the gradient from Color Ramp. Then click the Classify button to generate the values. Click OK.
Here’s what it looks like
Create a path from points
Finally we’ll create a path layer that connects all the markers. From the Processing Toolbox sidebar on the right type into the search points to path and double-click it when it comes up.
In the window that pops up the default settings are good, so click ok.
The path is generated on a new temporary layer. It needs to be written to disk to save it in your project. Right-click the Paths layer and select Make Permanent....
In the window that comes up, for Format select GeoPackage then for File name click the ... to choose where you want to save the new file. Click the OK button.
Now you can uncheck the sun_analemma_2024 layer to hide it and only the path will be visible.
Raster Landmass
You can use raster data to make the landmasses look pretty. I recommend this one: Natural Earth. You’ll need to add it as a raster layer rather than a vector layer.
