 ===== How to start downloading =====
@@ Line 22: / Line 23: @@
 Keep in mind that all maps in Locus Map consist of **square tiles** of 256px or 512px per side. All downloads work with whole tiles so it is not possible to download precisely round or curved maps - all are composed of square pieces of the map.

+==== Selecting zoom levels ====
 Your download area has been defined, the next step is to choose **which zooms to download**. The zoom selection screen consists of the following parts:

 In case you download a **paid map** Locus Map displays another dialog. It summarizes your **[[manual:user_guide:locus_store:locoins|LoCoin]] credit**, the final price of the downloaded map, the number of tiles in the packet, and the price of 100 tiles. If you have enough credit for the purchase there is no other obstruction to begin downloading.

-{{ :manual:user_guide:mapdownload4.png?nolink |}}A downloading progress info-box emerges after the download is launched.

-The free map providers define **daily download limits**. Each provider has a different limit. If you add a **[[manual:advanced:customization:online_maps|custom online map]]** to Locus, we limit the download to 10000 map tiles daily in order to protect the map provider's server from overloading.

+===== Map caching =====
+Some online maps can't be downloaded, i.e. saved as a map file forever, but can be **cached**, i.e. stored into temporary memory. Temporary means that the cached map has **time-limited availability** for offline usage.
+A typical case is an **online LoMap** which can be cached for **90 days** and the base **Satellite map** which can be stored in the cache for up to **one year**. The cache timeout of each online map is displayed in its description:\\ {{ :manual:user_guide:mapdownload8.jpg?nolink |}}
+==== How to cache a map? ====
+  * **select** the map from the map manager
+  * **browse** thoroughly through the **whole area** of your interest on the map screen
+  * do so across **all zooms** you want to cache - make sure **all map tiles of the area are properly loaded**
+And that's it. When you activate the cached online map when you are offline it will display the same way as it is downloaded.
