This time, I wanted to prepare data easily, so I used MapTiler DATA by MapTiler, which allows you to download map tiles (MBTiles) for a specified area.Ĭlick DOWNLOAD DATA in OpenStreetMap basemaps.Įnter any region in the search window and select it → Click DOWNLOAD. In general, map tiles (MBTiles) can be created with OpenStreetMap and proprietary data by using the following tools. Prepare " MBTiles" to store map tiles built-in SQLite for conversion of COMTiles. This article will be of some help to those who are considering introducing COMTiles! One of the reasons for PMTiles' popularity is due in part to its extensive documentation. The technology of COMTiles is excellent, but it is not yet easy to introduce because the library is not published in “npm,” and the documentation is incomplete. COMTiles are often compared to PMTiles, but I have the impression that PMTiles are becoming more popular these days. This time I examined COMTiles(Cloud Optimized Map Tiles). No pre-tiling process (vector tiles and raster tiles) is required.įor vector files, there are many formats, and they are not yet settled.Only a single file needs to be placed in storage to process requests from the front end.Only a part of a vast file can be requested.The features that personally struck me are as follows. The folder output format is suitable for small maps, or if you have your own hosting solution.I have COMTiles (Cloud Optimized Map Tiles) hosted on Amazon S3 and visualized with MapLibre GL JS □Ĭloud Optimized is a cloud-optimized format that enables a single file to process requests for massive location data that previously required a map delivery server and tile splitting process. You can also use upload the GeoPackage file to S3-like service and host it from there. For larger maps use GeoPackage and upload to MapTiler Cloud for fast and stable access. If you render smaller maps or maps for your mobile device, use GeoPackage or MBTiles, depending on your preferences or software support. The generated GeoPackage file (.gpkg) can be compliant to MBTiles format which makes it compatible with many viewers and software tools.ĭirect upload to MapTiler Cloud, Amazon S3, or Google Cloud Storage from MapTiler Engine supports GeoPackage. Apart from Mercator projection, GeoPackage supports other coordinate systems, which are often country-specific. It is also a single file, that can be easily loaded to any hosting and the upload time is short. GeoPackage is an exchange format standardized by Open Geospatial Consortium. MBTiles are also suitable for the import of maps into mobile devices. However, the response for the users of your website is a bit slower than for the Folder structures. MBTiles is a single file, that can be easily loaded to any hosting and the upload time is shorter. To load a folder on the hosting server takes longer, but the response on the website is then faster. The folder contains a structure of different tiles sorted into directories according to the zoom levels. Each option has advantages and disadvantages regarding the speed of serving tiles, the simplicity of manipulation with output, and viewing software support. This article will show you how to choose the best and most suitable output format for your maps generated by MapTiler Engine.Īfter you are done with georeferencing and one step before the rendering, it is possible to decide, whether you want to save your maps as a Folder, as an MBTiles file, or in a form of a GeoPackage.
