Online maps

OsmAnd Online maps are an extensive addition to the already comprehensive base of OpenStreetMap data the application uses. With this plugin, you can add layers to your map with information from a different source, beginning with the satellite, or hiking routes view and ending with quite specific data like fire hydrants' locations. You can also change the main source of the map from vector maps to online tiles.

Many new useful map sources you can find in Anygis project.

Online map formats of OsmAnd:

Advantages:
  • To save traffic or storage space when offline map is not available. Usually for small areas, online tiles are more compact.
  • Display time is significantly faster, because maps are not rendered by the device.
  • It is possible to cache online maps with MapCreator or SASPlanet for the offline usage.
Main disadvantages:
  • It is reasonable to use only for small areas since the size of online tiles for a country could be more than several GB.
  • No switch between different styles of the map.
  • No additional layers available like transport or POI on the map.
  • It is not possible to rotate map with readable text (text will be rotated with the map itself, thus will not be easily readable).

How to use for Android

Not only can you use one map, you can also add up to two of the online tiles to the basic layer: open the app menu-> Configure map-> Underlay and an Overlay maps to combine three of them on the screen. For instance, you can open a basic OsmAnd offline vector maps, then add a satellite view for the overlay, and put cycling routes map underneath.

You can set the base map transparency for your layer and whether display the transparency slider on the main screen or not.

But how to view all thee maps without getting lost in the details? Simply adjust which information from the map you need and set the transparency of the layer. For example, combining Microsoft Earth map with the basic OsmAnd offline vector map can be very helpful. You can hide all the excessive data from the map and simply overlay roads over the satellite images. To set the features you would like to hide from the current map, just go to Configure map-> Hide and select buildings, polygons, boundaries or all of them together.

How to prepare raster maps

Despite the plugin being called 'Online Maps', you can use the maps without the internet, as well. You just need to save the parts of maps (often called tiles) to use them later. To do that, download a specific Map Creator tool developed by OsmAnd team.

Select the area you need to download, click on the Preload area, then set the smallest and the largest zoom levels you want to display and download the tiles.

For Android version you can copy them to your phone's osmand/tiles/*tile type* folder. You'll also need to open the Configure map-. Overlay map and choose OsmAnd online tiles.

For iOS version you can choose SQ Lite file in your phone (any messenger or dropbox), OsmAnd will suggest to add it. You'll also need to open Map-> Overlay / Underlay or Map type and choose new map source.

How to add SQ Lite file in Android and iOS version of OsmAnd you can read in Anygis project.

Online tiles can be helpful when you need just a small section of the map or a specific type of it to use in the limited area, but don't want to download the whole region. They can come in handy in endless situations.

Mobile Atlas Creator

You can also create your own map tiles using the Mobile Atlas Creator (MOBAC) software. It is a free open-source map creating tool you can use to make offline tile maps from different sources. Just download the program, then run it. In the format choosing dialogue pick OsmAnd SQ Lite or OsmAnd tile storage. SQ Lite is a single file with the selected area while tiles are separate pieces of the map gathered on your device. SQ Lite often happens to be more convenient as it is stored in one place and occupies less storage space. Select an area, then choose an 'atlas' option, press Add selection and then click Load to save your tiles. You can also pick the map source, zoom levels and other features before loading. How to add SQ Lite file in Android and iOS version of OsmAnd you can read in Anygis project.
