We had worked on multiple election maps before, for example the 2017 federal election in Berlin
, but due to the enormous amount of data, this one was more of a challenge. Although we had already developed a map with the same number of geometries
, this time we wanted to use more modern technologies and switch from raster-only to a combination of raster and vector tiles. This had the advantage of showing a mouse-over effect on higher zoom levels and improving the general performance of the map.
