GIS , ONLINE MAPS and OFFLINE MAPS

WHAT IS GIS?

A geographic information system (GIS) is a system designed to capture, store, manipulate, analyze, manage, and present all types of spatial or geographical data.

What does GIS do?

It locates:

• Assets, (water and sewer pipes)
• Areas, (land use)
• Incidents, (crime statistics)
• Characteristics (disease mortality rates)
  
• GIS is a way of organizing database records by tying them to geographically synchronized slices of the world so that “where” questions can be asked and answered.

WHY OFFLINE MAPS

There are plenty of reasons to download maps and store them on your Phone, not least the fact you won’t need an Internet connection to get around – even if your signal drops when traveling in remote locations, you’ll still be able to depend on Offline data to search for places, plan routes and navigate. 

Going offline makes things a lot cheaper

Download the maps using your Wi-Fi connection when you’re at home, and you won’t get caught out by roaming costs when you travel abroad. Going offline also means you won’t be using up your allotted data if you’re on a contract with a limited amount of data.

Faster than The Flash

It’s not just about cost, as offline mode also boasts loads of other benefits. It’s particularly fast to load, and because all the information is already stored locally on your phone, you won’t need to wait while route information or map tiles download, even when you’re panning or zooming the map. There’s no stuttering, no buffering and no chance of missing your turn while the connection catches up with your position.

No signal? No problem

Head out into the countryside, and there’s a good chance you’ll also take a hit when it comes to connectivity. And although there may be more telephone masts in the heart of a city than in the countryside, that doesn’t guarantee a good mobile reception: tall buildings can have an impact on your network connection. With the maps on your phone, however, none of these problems will matter one bit, and you’ll still be able to see exactly where you’re going wherever you are.
