What You'll Learn
Using Blender
Blender is a community-driven, free, and open-source software for 3D modelling, animation, rendering, and more. It is a versatile 3D creation suite that can render maps with realistic lighting and textures.
To create a 3D map of Australia using Blender, you will need two images: a map of Australia and a digital elevation model (DEM) covering the area. DEM images can be downloaded from various sources on the internet, such as government open data portals.
Once you have the required images, you can follow these steps:
- Prepare the DEM data using QGIS to render 3D-looking shaded relief maps in Blender.
- In QGIS, use the "Raster > Extraction > Clip Raster by Mask Layer" function to clip the DEM to a specific area. Use a polygon of your area of interest (in this case, Australia) as the "mask layer." Ensure that the polygon and the DEM have the same projection.
- Open Blender and set up your camera by selecting it in the object collection. Set the location X, Y, and Z values to 0, and adjust the rotation and orthographic scale as needed.
- Click the "Color" circle of the image texture node and drag it to the "Height" circle of the displacement node. Repeat this step, dragging from "Displacement" of the displacement node to "Displacement" of the material output.
- With the plane selected, go to the Shader Editor and click the Options tab. Set the displacement to "Displacement and Bump."
- Render the image by clicking "Render > Render Image" or using the F12 shortcut.
- To add colour, include a colour ramp that will use the DEM to determine the colour of each pixel.
- To add more detail to the map, use the displacement method to create the 3D model.
- Finally, export your 3D map as a PNG file with a transparent background.
By following these steps, you can create a 3D map of Australia using Blender, adding colour and detail to bring your map to life.

Scaling and accuracy
One key consideration is the scale of the 3D map. Australia is the sixth-largest country globally, spanning 7,617,930 square kilometres (2,941,300 square miles). When creating a 3D map, deciding on the appropriate scale is essential. A larger scale map will allow for more detail, while a smaller scale map may require generalising certain features.
The highest point in Australia, Mount Kosciuszko, stands at 2,228 metres above sea level. When creating a 3D map, representing this elevation accurately while maintaining a manageable map size can be difficult. For example, on a 1200x1500mm map, the highest point would be represented at a minuscule 0.84mm. This scale challenge may require creative solutions, such as assembling the map in sections or utilising advanced 3D cartography techniques.
To ensure accuracy in the 3D map, precise elevation data and advanced 3D modelling techniques are necessary. Software programs like Rhino and Fusion360 offer tools specifically designed for translating images into 3D surfaces and creating height maps. These programs enable the transformation of elevation data into detailed 3D representations, ensuring an accurate portrayal of Australia's diverse landscapes, including its mountains, valleys, deserts, and coastlines.
Additionally, the use of state-of-the-art geospatial visualisation and digital terrain models can further enhance the accuracy and visual representation of the 3D map. These technologies allow for a comprehensive analysis of the country's terrain, making the map suitable for educational, professional, and personal applications.
Overall, achieving accurate scaling and representation of Australia's diverse terrain in a 3D map requires careful consideration of size, elevation data, and the utilisation of advanced 3D modelling techniques and technologies.

File formats
When creating a 3D map of Australia, there are several file formats that can be used, depending on the software and tools you are working with. Here is an overview of some commonly used file formats for 3D maps:
- PNG: This format is widely supported and allows for transparent backgrounds. It is suitable for creating print files for posters, brochures, or flyers, and can also be easily integrated into various layouts.
- Vector Formats: Vector graphics files, such as AI, EPS, and PDF, are commonly used for 2D maps and can be easily edited and scaled without loss of quality. They are ideal for creating printable maps with clean, sharp lines.
- STL: This format is commonly associated with 3D printing. It is used for storing 3D model data and can be exported from various modelling software. STL files can be further edited using 3D printing software or prepared for printing directly.
- SKP: This format is associated with SketchUp, a 3D modelling software. SKP files can include topography and 3D buildings, and they can be generated using the SketchUp application.
- OBJ: OBJ files are commonly used to represent 3D objects and are often used in conjunction with 3D modelling software like Blender. They can include terrain data and are suitable for printing.
- BLEND, PLY, FBX, X3D: These formats are associated with Blender, a popular 3D modelling software. Files in these formats can be opened in compatible software packages and used for further editing or 3D printing.
It is important to choose the right file format that is compatible with your software and intended use. Some formats may be more suitable for printing, while others may offer more flexibility in editing or visualization. Additionally, consider the availability of tools and software that can open and edit these file formats to ensure a seamless workflow.

Australia's topography
Australia is situated on the lowest, flattest, and oldest continental landmass on Earth. The topography of Australia is largely the result of prolonged erosion by wind and water, and its shape is the product of tectonic plate movements and long-term changes in sea level. These geological forces, such as tectonic uplift and clashes between plates, occurred mainly in its early prehistory when it was part of Gondwana.
The Australian continent can be divided into four major landform regions: the Coastal Plains, the Eastern Highlands, the Central Lowlands, and the Western Plateau. The Coastal Plains are a narrow strip of flat, highly populated land along the east continental coastline of Australia from Queensland to Victoria. Much of the centre of mainland Australia is also flat, but there are numerous ranges such as the MacDonnell and Musgrave Ranges, as well as individual structures like Uluru (Ayers Rock).
The Eastern Highlands, in the southeast of the country, consist of a series of mountains in the south topped by Mount Kosciuszko, which is the highest mainland mountain in Australia at 2,228 meters above sea level. Further north, the Eastern Highlands include volcanic plugs, ash domes, and flow remnants. The Central Lowlands are also relatively flat, with some low mountainous ranges in the north and isolated uplands in the Northern Territory.
The Western Plateau, which makes up more than half of the country, is a flat area about 183 meters above sea level with low mountain ranges in the north. Tasmania, an island state, has its own distinct topography. The Midlands, in the central east, are fairly flat and used for agriculture, while the Central Highlands in the central west are the most mountainous region.

History of mapping
The history of mapping in Australia is a long and complex one, dating back thousands of years. Early maps of the continent were often based on guesses and speculation, with explorers only accidentally bumping into Australia's shores in the early 1600s. These early encounters, such as Dutch explorer Willem Janszoon's voyage to the western shore of the Cape York Peninsula in 1606, provided some of the first recorded encounters with the Australian continent and its Indigenous people. Janszoon's maps, though rudimentary, began to outline the western parts of this mysterious land.
In the late 18th century, British explorer Captain James Cook embarked on a voyage that would prove transformative for the Australian timeline. During his first voyage to Australia in 1770, Cook meticulously mapped the east coast of Australia, claiming it for Great Britain and naming it New South Wales. Cook's maps were remarkably accurate and provided a detailed depiction of the coastline, a significant improvement from the speculative maps of earlier centuries. One of his most well-known maps is the "Chart of the South Coast of New Holland," which accurately depicts the eastern coastline, including the discovery of Botany Bay and the Great Barrier Reef.
Following Cook, explorers like Burke and Wills led expeditions across the continent, with tragic results. Lacking bushcraft and unwilling to learn from the local Aboriginal people, they died in 1861, becoming tragic heroes to European settlers. In contrast, John McDouall Stuart successfully traversed central Australia from south to north in 1862, mapping out a route later followed by the Australian Overland Telegraph Line.
The completion of the telegraph line in 1872 was associated with further exploration and mapping of the Australian interior, including the Gibson Desert and the Nullarbor Plain. By the late 19th century, a majority of people in the Australian colonies were native-born, though still largely of British and Irish heritage. The push for an Australian federation within the British Empire gained momentum, with nationalists speaking of a shared "Britishness" as a basis for unity.
The modern nation of Australia came into existence on 1 January 1901 as a federation of former British colonies. However, the human history of Australia is much older, with the arrival of the first ancestors of Aboriginal Australians between 50,000 and 65,000 years ago. The artistic, musical, and spiritual traditions they established are among the longest surviving in human history. Today, maps continue to play a crucial role in understanding Australia's diverse landscapes and cultural heritage.
