 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 =====
+==== 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:

       * //advanced options// - a table of available zooms with checkboxes. Each zoom level contains information about the map tiles number and estimated data size. Allows to define precisely which zooms to download and which not.\\ {{ :manual:user_guide:mapdownload3.png?nolink |}}
-===== Advanced options and confirmation =====
+==== Advanced options and confirmation ====
 The Advanced options menu offers accurate **calculation** of the final amount of map tiles which is especially useful when downloading **paid commercial maps**. Then there is an option to set the **download type**:

   * //Compressed map (TAR)// - an obsolete method preserved for users of Trekbuddy and other older systems. Useful also for further post-processing of TAR map tile archives.
 **Overwrite** - define how old tiles should be rewritten in case you download cached or supplementary maps. Set **"0"** if you want to re-load all map tiles.
-===== Paid online maps =====
+==== Paid online maps ====
 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. Besides useful information, it offers to **abort the downloading process** (and lose all already downloaded data without the possibility to restore the process) or **pause it** - then the already downloaded data is saved and the process can be **renewed** from the main download dialog box.

-===== Download limits =====
+==== Download limits ====
 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 per day 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.
