Presentation of the work we've done to adapt the OSM Carto style to vector tiles. We will take you through the making-of the cartography, step by step, scale by scale. Available on MapTiler Cloud (https://cloud.maptiler.com/maps/openstreetmap/), the style will be integrated into the next version of the OpenMapTiles project. We will also show you how to use this style in QGIS and how to display it on 3D maps with MapLibre.

Global dataset and a map style for hiking and biking developed from OpenStreetMap - that's MapTiler Outdoor. During development, we have to solve multiple challenges originating from a lack of international standardization in trail marking.

MapTiler Outdoor is a global dataset and a map style for hiking and biking available as a zoomable and web-compatible vector tiles, which are ready for use in OpenLayers, MapLibre, Leaflet, QGIS as well as mobile applications. After first excitement, challenges starts to appear one after another: most of them originating from a need to create a rigid set of rules for the entire world, which is full of diversity due to the variety of nature. We also faced the challenge of lacking international standardization for hiking trails, which is unique for each country (and even on this level with many exceptions and specialities - like oneways, via ferrata routes or even climbing trails). And last, but not least, we have to dig all this information from the OpenStreetMap and turn it into a map understandable for everyone. We managed to create a layer with trails and corresponding points of interest, which can be filtered on hiking or biking in the customize tool. This layer can be overlaid on top of any map. However, we created a specialized map style which combines OpenStreetMap with contour lines and hillshade and highlights things you need for moving around in the nature. The schema of MapTiler Outdoor is based on the open-source OpenMapTiles (OTM) schema and data are processed using OMT stack. MapTiler Outdoor is available via MapTiler Cloud as a service or in a form of a data package for download.

OpenMapTiles is an open-source set of tools for processing OpenStreetMap data into vector maps, which can be produced in various coordinate systems.

OpenMapTiles is an open-source set of tools for processing OpenStreetMap data into zoomable and web-compatible vector tiles, which are ready to use in OpenLayers, Mapbox GL, Leaflet, QGIS as well as mobile applications. This talk gives an overview of the OpenMapTiles tools to produce vector tiles in coordinate systems other than Mercator while keeping all the features, such as interactivity to create powerful region-specific applications. Today’s de-facto global standard is a Spherical Mercator projection because it preserves shape and angles. The entire world looks like a square, which makes it easy to work with on a computer. However, such a transformation causes several issues like distortion of sizes where places around the equator are visually smaller than those near poles. That’s why new global coordinate systems were developed. There are also many local coordinate systems with a long tradition. They perfectly fit the need to display a particular country/area in the most acceptable way. They are heavily used, especially by governments. OpenMapTiles can serve as a base map for displaying data in a different coordinate system or for view/print purposes. There is also a hosting service based on OpenMapTiles called MapTiler Cloud, which offers the same ability to be displayed in a different coordinate system than Mercator.
