Hungary is an important subject of our work at ATLO. I realized that since I have been working with Attila. It is a very fascinating topic, mostly because it has a lot of untapped potential. If we are not telling some bigger story of the country, it still has a lot of aspects that can be visualized. Here, we went to ground zero, and used the building blocks of all the projects that has to do with Hungary: the administrative polygons. A seemingly simple work, but we still hit some obstacles. Namely, the projection of the polygons in Tableau – the software in which we made the basis of the final image – was not perfect, the shapes were slightly distorted. Here, I learned that it is vital to save your geojson files in QGIS in the right projection. Some apps, like Kepler.gl doesn’t even recognize the file if it is in a “bad” projection. In this case, Hungary is shown without distortion if it is not saved in the default WGS84//EPSG:4326 projection but in HD72/EOV//EPSG:23700 instead.
