On this page I show you how to create offline maps on your Mac or PC and copy them with iTunes to Looking4Cache. L4C supports two different offline map formats:
- ‘RMaps SQLite’: This files you can create with MOBAC. It downloads the ready rendered map tiles directly form the different map servers. Because of the high trafic MOBAC causes by OpenStreetMap it gets blocked sometimes. So you may have to switch the map provider.
- mbtiles: This files you can create with TileMill. In difference to MOBAC the tiles (256×256 pixel picture of a map) will be rendered localy on your computer. It is possible to modify the style of the maps with StyleSheets. But it is also a litte bit complicated to setup a TileMill environment.
I work on the integration of vector maps. But this will take some time.
- Download the last version of MOBAC frm their homepage (you find the download on the buttom of the page): http://mobac.sourceforge.net
- Unzip the file in a directory you want (for example Desktop, Applications, Programs).
- Mac: Start the file ‘Mobile_Atlas_Creator.jar’
- Windows: Start the file ’Mobile Atlas Creator.exe’
Create a offline map
- MOBAC will ask you to name the new atlas and select a format. Enter a name ans select the format “RMaps SQLite”.
- Later you can open this dialog again with the menu ‘Atlas / New Atlas’. But don´t forget to save your atlas as a profile.
- The usage of MOBAC is quite simple. With the mousewheel you can zoom. Hold the right mouse key to move the map.
- Select a map source on the top left.
- Select a area on the map with the left mouse key pressed. The red marked area will be exported later.
- Select the zoom levels to export. Higher numbers have a larger detail.
- Click on ‘Add selection’ to add the zoom levels of the selected area to the export. You can add different selections with different zoom levels to one offline map.
- Click on ‘Create atlas’ to export the offline map.
- After the map is stored offline you can click on ‘Open atlas folder’ to jump into the directory with the map.
Starting with TileMill (download) is more complex that just download the map tiles because you have to provide map data to this program through a database.
After the installation of TileMill you have only a program with some examples. What you need to render your own maps is a database containing OSM data and a style for this data. Both you get with OSM Bright. Heres a installation guide for Mac and Ubuntu.
Note: mbtiles will be support in Looking4Cache version 1.2.
Copy the offline Map to the device
- Connect your device and open iTunes.
- Click on your device and select ‘Apps’. Scroll down to the section with apps that supports file transfer. Choose ‘L4C Pro’ here.
- Drag the newly created offline map from the Finder / Explorer in the list of files. The tansfer starts immediately.
- Note: With iTunes you can also delete maps. Don´t delete the ‘database.sqlite’.
Open the map in Looking4Cache
- Tap the map icon on the map screen. It is the second icon on the top.
- The offline map will be presented at the bottom of the list.
- Congratulations! Now you are independent form the Internet while caching.
