Enrich styles and enhance styling process with OpenMapTiles / FOSS4 2022

https://talks.osgeo.org/foss4g-2022/talk/HVUKHK/

Vector tile map is now industry standard and general-purpose schema is available on OpenMapTiles project. But if the features that people focus on in your own country are different from the default schema? We developed styles to cover and highlight Japanese authentic geographic attributes such as railways, hot springs, and religious facilities with an improved OpenMapTiles schema. The styles are available on MapTiler Cloud as MIERUNE styles globally. In the process, we developed some useful tools for vector tile styling. One is a style-competing tool that makes it cartographers easy to compare two versions of styles interactively. Another is a kind of style management tool using git that visualizes diff of style.json and takes screenshots automatically. Structured approaches of planning and implementation of vector tile styling are not much shared. In this talk, we will speak about how to enrich the styles for your own country and enhance the styling process for vector tile cartographers.
