Locus Map developing company Asamm Software provides its own maps based on OpenStreetMap Data and rendered directly in Locus Map application via MapsForge toolbox:

• LoMaps cover the whole World in map packets covering individual states
• they are purchased and downloaded solely for offline use
• they are smaller in data size than maps downloaded from the online mode
• LoMaps can be switched into several themes: hiking/biking, skiing, town plan and road map. Each theme is based on the same map data but displays different layers and symbols according to the user's needs.

• map data - line, space and point objects
• offline addresses - beginning with LoMaps 2016/04/01- addresses can be searched for
• points of interest - can be clicked in order to display their detail, can be browsed or selectively displayed
• elevation data - necessary for terrain shading, route elevation profile rendering etc. It can be downloaded additionally after LoMaps packet download.

LoMaps can be purchased in Locus Store that is accessible by two ways:

• from the Map Manager - select Offline Maps tab in the Map Manager and tap the Add maps button in the bottom right corner - select Offline maps download
  
• from the Main Menu - select Store

When you find your desired map, select it and the map information screen appears. It contains important information about date of the map update (LoMaps are updated approx. once in two months) and its size in MB before and after unpacking. To start downloading just confirm the purchase.

Purchased maps appear in Offline maps tab of your Map Manager in folders sorted by country.

You can download your purchased LoMaps from the server as often as you like for the whole time of its availability. When your LoMap version is not available any longer, you can download the next oldest available version for free again.

Each vector (or other) map that contains themes or theme layers activates option to switch these themes. There are a few ways how to do this:

• Content panel switch - switch placed in the Content panel.

All these methods display the theme menu:

Here you can select the map theme - internal or external (custom). Some themes contain also switchable layers of specific datasets. This way you can fine tune your map content:

Names of cities, towns and villages in exotic destinations can be sometimes difficult to read for Westerners: OpenStreetMap data, therefore, contain transcription of local names in English (or sometimes also other languages). The language switch can be found in a LoMap detail screen:
Open the language menu and select language you understand. Not all names are transcribed, it depends on activity of the local OSM mapping community. The same map with English-transcribed names
