![]() LAS can be rendered in QGIS using the Point Cloud data input.Īnd after setting it up, it can be also displayed in the 3D view. PDAL project is very similar to GDAL so the command used for data transformation should seem known. To convert between LAZ and LAS formats, we can you the PDAL library and tools. LAZ is just compressed (zipped) LAS file without information loss. The format is widely used and regarded as an industry standard for lidar data. It is an open, binary format specified by the American Society for Photogrammetry and Remote Sensing (ASPRS). The LAS (LASer) format is a file format designed for the interchange and archiving of lidar point cloud data. The LAS file will later be converted to Cesium 3D tiles file structure. For your approach, we need the LAS format as input. They are usually stored in LAZ or LAS data formats in form of so-called point clouds. MapTiler is providing global terrain 3D data tiles, which can be used along with the CesiumJS library to present the maps in the 3D context. The platform allows to display and interaction with 3D geospatial data, which can be buildings, terrain data, or point clouds (e.g. It is mainly the (open source) JavaScript library, 3D data publishing portal, and a private company, which is developing the whole platform. Clicking the "Render" button will start the rendering process.Īfter the rendering is finished, you'll be taken to the vector tiles viewer in inspect mode, where you'll be able to see the properties of all the rendered features.Ĭlicking the "Continue" button will take you to the final page, where you can upload the tiles to MapTiler Cloud (if you chose GeoPackage or MBTiles as the output format) or use another service of your choice.Īnd that's it! You might also want to learn how to style your vector data in MapTiler Cloud or get some more advanced tips for generating vector data.Cesium is a platform for 3D Geospatial data and software applications designed to unleash the power of 3D data. You can also edit the metadata of the generated map there. In most cases, you'll want to leave these settings unchanged. Next, you'll be taken to the page where you can turn the tile compression on/off or change the tile size. You can also set minimal and maximal zoom levels for the final tiles. You can rename the output layer, edit key=value attributes for each feature or remove them. MapTiler Engine will automatically prepare output layers for your final tileset, with all of the attributes of your source vector data. If you're not sure which one to choose, please refer to the article that compares Folder, GeoPackage, and MBTiles formats. Next, you'll be prompted to select an output format for your tiles. The raster tiles are rendered with MapTiler Engine. However, you may want to change the coordinate system for your map or the geographical location of your data (Note: Assigning location visually functionality is not available for vector tiles). The OpenStreetMap vector tiles are made with our open-source software released at. ![]() At this point, you can proceed by clicking on the " Export" button. MapTiler Engine will automatically set the CRS and geolocation of the rendered map. If you need some sample data to test MapTiler Engine on, you can download one of the Natural Earth datasets. For the list of supported vector file formats refer to this link. Just start the application and open the file with your geodata. Rendering vector tiles with MapTiler Engine is really easy. Rendering vector tiles with MapTiler Engine You'll find a few related sources listed there. It works efficiently across all major desktop and mobile platforms, can be extended with lots of plugins. MapTiler team is the original author and the main contributor to the OpenMapTiles project, MapLibre, OSMNames, and other open-source projects. ![]() Instead it focuses on making the basic things work perfectly. The option is available since MapTiler Engine 10.0 in all editions including MapTiler Engine Free.įirst, if you want to learn more about vector tiles in general, what benefits they bring to users, why would you want to use them or what is their history, please head to the "Useful links" section at the end of this article. Leaflet is a lightweight open-source library for online maps. In this article, you'll learn all the important information about generating vector tiles using MapTiler Engine.
