Using Aotearoa New Zealand’s Open Data with QGIS and Blender to create two map styles

Abstract. This article explores the use of open data, QGIS, and Blender in the creation of two distinct map styles. The New Zealand government’s commitment to open data is demonstrated by the availability of extensive geographical data through the LINZ Data Service and other free providers. The first map style, Natural Basemap, uses land cover and elevation data to produce a pseudo-realistic map. Terrain shading and texture application are used to enhance visual realism. The second style, Perspective Linework, uses Blender’s Freestyle non-photorealistic rendering engine to depict topographical features such as ridgelines and creases from 3D terrain models. Both styles offer innovative approaches to visualising New Zealand’s topography, using open data and software to create visually compelling maps.
