# Generating vector tiles for offline use Use following parameters to set the Vector Tiles connection: Set the parameters of the Vector Tiles connection:Īnother source of online vector tiles are Qwant maps.Right-click on Vector Tiles and select New Generic Connection.In QGIS, navigate to the Vector Tiles in the Browser panel.For example, we can add ESRI Basemap vector tile (QGIS 3.16+): They are smaller in size, have flexible styling and your maps will not be pixelated even when zoomed in. Vector tiles are a better alternative for cartographic maps as background data.

See how to work with large files in Mergin Maps Input. Browse to the folder where you want to save the MBTiles and name the file.ĭepending on the size of your study area and the zoom level, the output file can be very large. Output file (for MBTiles): click on the right side drop-down menu and select Save to file.Extent: click on the right-side drop-down menu and select Use Map Canvas Extent.Set the parameters of Generate XYZ tiles (MBTiles) tool: In Raster tools, double-click on Generate XYZ tiles (MBTiles) In the search section on the top of the Processing panel, type xyz to display relevant tools. The Processing panel will appear on the right side of QGIS window. In QGIS, select Processing > Toolbox from the main menu. To generate an offline copy of the aerial imagery from your map view extent: added the Bing aerial imagery to the QGIS project.QGIS also offers a processing algorithm (opens new window) to generate your own XYZ tiles (opens new window) for offline use. # Generating raster tiles for offline use This will ensure the fonts are readable on the high resolution screens (the majority of the recent smartphones comes with high DPI screens). When using XYZ tiles that contain labels, ensure to set the tile resolution to Standard in the connection settings. Double click on it to add it to your project and zoom to your area of interest. Now, the XYZ Tiles in the Browser panel should contain the Bing aerial imagery. Set the parameters of the XYZ connection: Right-click on XYZ Tiles and select New Connection In QGIS, navigate to the XYZ Tiles in the Browser panel To add Bing aerial imagery to your QGIS project: You can also add other sources (opens new window) of XYZ tiles to your QGIS. When adding a cartographic basemap, ensure you set the tile size correctly, so that the texts and labels are readable on mobile devices with high resolution display. QGIS comes by default with the OpenStreetMap online services for XYZ tiles (opens new window). They can be large in size and can appear pixelated when zoomed in. Raster tiles are ideal for aerial imagery or terrain visualisations. The following sections will cover two types of background maps for online and offline use in Mergin Maps Input: raster and vector tiles. It is the sole responsibility of the end user to comply with such terms and conditions.
This page simply explains how to add the data to your QGIS maps and use it in Mergin Maps. Note that you need to comply with the terms of use of the background maps and their data sources. There are several sources of online and offline background maps you can use in your QGIS project. When surveying in the field, it is essential to have appropriate background maps.
