![]() There is an error in the console that "Uncaught ReferenceError: g is not defined", which is not so much helpful to debug the issue. I can see the request for map data is 200 OK, and the JSON data for the map returned is correct. The network tab seems fine - no CORS issue or failed requests. However, when I build and publish the site, the map is not getting rendered. I have got the API keys for both, and it gets rendered properly in localhost environment. What is the technology behind and how can you adapt it already today? Raster tiles, vector tiles, and what is the difference Raster tiles description Vector tiles are becoming a new trend and are most likely the future of map publishing.I am working on a react application which have two maps (one leaflet+esri map and the other is maptiler). Traditionally, web maps were based on raster tiles technology. It was a set of squared images placed next to each other, each with a fixed geographical area and scale. The rest was delivered to your browser when you changed the position or zoom.Ī more detailed guide about raster tiles can be found in this document.Ī map divided into raster tiles Vector tiles description Together they were creating the whole world, but only tiles you were actually browsing were shown. Vector tiles, which were introduced later, also deliver data that are divided into roughly squared tiles. But instead of raster images, there are pre-generated vector data that are present on the requested area. ![]() Map elements that overflow current tile are cut with a specific offset, which is essential when connecting tiles together. Vector tiles are rendered on the client side. A map style defines the look of all elements in tiles. The style says what map element should be rendered, which color, which font should be used for a label, and which language this label should be rendered. It gives more opportunities to change the map on the fly with minimum effort. Vector tiles are transferred over the web in the form of packed geographic data in vector format split into squared tiles.īecause of this flexibility and the possibility to render raster tiles from pre-generated vector tiles on request if needed, most of the big players in the mapping industry have already switched.
