 c:geo supports a fully automated download and installation of offline maps from various sources.
-The c:geo map downloader can be started in two ways:
-  * From the [[.:mainmenu:livemap|map view]] by opening the map selector and tapping on ''<Download offline map>''
-  * From the [[.:mainmenu:settings|map settings]] by selecting ''Download offline map''
-==== Map downloader ====
-After opening the map downloader you can choose from what source you would like to download the map by opening the drop down menu shown on top. To learn more about the different map sources, please take a look at [[.#mapsources|this list]]
-===== Manual download and installation =====
 ==== Download sources ====
+{{anchor:mapsources}}
 First of all you need to download a compatible offline map file covering the needed geographical area. There are several services available on the internet providing frequently updated and ready-to-use map files.

 The table above does only provide some examples of map providers, there are more of them out there.
-==== Installation ====
-<WRAP center round info 100%>
-Users reported, that some (vendor) tools used to transfer files between PC and smartphone might corrupt or alter the files during transfer. Therefore we recommend to download all files directly onto your smartphone and use a good file explorer on the device to decompress/copy/move the files as described below.

-=== Map files ===
+The c:geo map downloader can be started in two ways:
+  * From the [[.:mainmenu:livemap|map view]] by opening the map selector and tapping on ''<Download offline map>''
+  * From the [[.:mainmenu:settings|map settings]] by selecting ''Download offline map''
-The downloaded offline map file needs to be stored onto your device in a folder of your choice. If the downloaded file is compressed (''*.zip'') you need to decompress it first. The correct file extension of the map file is ''*.map'' (e.g. ''germany.map'').
+==== Map downloader ====
-If you want to install several map files for usage with c:geo, you should store all of them into the same folder. As c:geo is later on configured to search for maps in a specific folder, all of them will be selectable in c:geo.
+After opening the map downloader you can choose from what source you would like to download the map by opening the drop down menu shown on top. To learn more about the different map sources, please take a look at [[offlinemaps#mapsources|this list]] or click on the heart icon shown on top right in the map downloader.
-{{:en:offlinemap_mapfile_location.jpg?direct&400|}}
+For this example we use "Mapsforge" as map source.
-For this tutorial, let us assume you stored the map file(s) to ''/sdcard/mymaps''.

-=== Themes ===
+The top level list is usually sorted by coarse geographical regions (typically: continents) and get more specific on each lower level. Click on the magnifier icon to open the desired list/region and see its contents. If you finally found the map file you want to install, simply click on the disc icon next to it to start the download process.
-If you (optionally) also downloaded a theme file for your offline map, you need to store it onto your device it in addition to the map files.
+<WRAP center round important 100%>
+Downloading a map can cause high network traffic! Make sure you use a Wifi or other non-metered network before starting the download.
+</WRAP>
-Typically the downloaded theme is compressed (''*.zip'') and needs to be extracted before it can be used by c:geo. The compressed file usually contains some folders and a lot of small files. Please make sure you keep this structure untouched when decompressing the file.
+Confirm the following dialog to start the download.
-All of the resulting folders and files need to be stored below a folder of your choice on your device.

-{{:en:offlinemap_themefile_location.jpg?direct&400|}}
+The download itself is performed in the background by the download manager of your device. When the transfer is complete, the file is copied to the c:geo map folder and set as current map automatically.
-For this tutorial, let us assume you stored the theme(s) to ''/sdcard/mythemes''.
+If the downloaded map requires a dedicated map theme (does not apply to Mapsforge) the downloader will additionally ask you, whether you also want to download and install this theme.
-==== Configuration ====
+FIXME PICTURE
-Once you finished storing the map files (and optionally themes) onto your device, you need to configure c:geo to use the correct directories for finding the maps/themes.
-You will find the corresponding settings in c:geo Menu -> Settings -> Map. A detailed description of this setting menu can be found [[.mainmenu:settings#map|here]].
-At the beginning the related settings will be empty:
-{{ :en:offlinemap_settings_empty.png?direct&400 |}}
-In this menu you need to select the directory, where you have stored the map files (and themes) in the previous step of this tutorial.
-Sticking to our example above you need to configure the following directories here:
-^ Menu item ^ Setting ^
-|Directory with offline maps|/sdcard/mymaps|
-|Map Themes Directory|/sdcard/mythemes|
-To select these folders simply tap on the related menu item. c:geo will then automatically scan your folders trying to find the map files and offer the corresponding directory to be selected. If the list already contains the correct directory you can directly select it, if your map/theme directory is not listed you have to tap the ''Choose directory'' button at the top to manually select/enter the directory.
-{{ :en:offlinemap_file_scanner.jpg?direct&400 |}}
-<WRAP center round tip 100%>
-On some devices finding the right folder might be frustrating, as the same folder is mounted under different paths at the same time, whereas the visibility of these paths might be different from app to app. A typical example is, that ''/sdcard/mymaps'' might instead be shown as ''/storage/emulated/0/mymaps'' or something like ''/storage/1234-5678/mymaps''. \\
-Due to the many different implementations depending on vendor, model, Android version and device configuration, we can't give a generic information, but you have to find the correct path on your device.
-</WRAP>
-If you select ''Choose Directory'' some file explorer (appearance differs depending on Android version and installed third-party tools) will be opened, where you can browse your folders and choose the correct directory.
-The following pictures show two different typical file explorers and visualize the steps needed to browse and select your map folder according to our example. For setting up the theme folder the steps are identical, but you need to select the themes folder instead.
-{{:en:offlinemap_chooser_cgeo_map.jpg?direct&300|}}
-{{ :en:offlinemap_chooser_locus_map.jpg?direct&300|}}
-Staying in our example the directory configuration should be shown look like this in the menu at the end:
-{{ :en:offlinemap_settings_done.jpg?direct&400 |}}
-Now you are ready to use your map files (and themes) with c:geo.
