Offline Map Packs can improve device usability in all situations but especially so when dealing with low quality mobile data connections and when working in areas where there is no available network service. Without map packs installed your device relies on an active internet connection in order to display the areas on a map, every time you move the map it takes time and bandwidth to display it.

Maps of high detail, enabling accurate measurement at street level take up a lot of resources; Areas are split up into tiles and different tiles are created depending on the zoom level.

When you have a map pack installed the device no longer uses the internet for its primary method of display, it already has the data is needs available without an internet connection. This can save the user from frustration, improves map response and can also save money on bandwidth consumed for repeatedly accessing the map tiles.

Unfortunately map pack file sizes can be quite large in comparison to what storage is available with today’s iPhone devices; this means it may not be possible to have your whole working area available offline. You can still offset some issues by using map packs in conjunction with a live connection and the device also uses caching technology to reuse tiles it has already downloaded.

Map packs are usually provided to you on a USB storage device. There are different file types and supported map formats. For example the maps for the whole of the UK are provided at levels 1 to 16 (these files total 7.4GB). This means when offline with these map levels you can navigate the top of the UK but you can’t zoom down to street level and identify premises borders.
