THE MAPS OF THE FUTURE

The modern map is no longer a printed publication we struggle with on a mountain peak, but digital, data-rich and dynamic. Thanks to satellite navigation, GPS-enabled smartphones, social networking and 3D visualisation technology, maps are becoming almost unlimited in their functionality and capable of incorporating real-time updates. 5.1. For instance, tourists will be able to plan their trips by using their phones to project a 3D map onto a wall. Then they’ll be able to manipulate it remotely with their fingers, adding layers of information such as landmarks, restaurants, recommendations from friends, as well as transport links and times. As digital maps can now be linked to an almost infinite number of data sets, they’re also going to become more personalised. Cyclists or surfers, for example, will be able to add whatever information they find relevant. And soon we may not only be visualising maps. 5.2. This kind of function in a map would also be an obvious advantage for people whose sight is impaired.

Not only does geo-location help us know where we are and what there is of interest around us, it can also show us where everyone else is, and what they think is useful and interesting. 5.3. Consequently, we receive real-time alerts from fellow drivers, and hopefully enjoy a less frustrating journey. In my area, over 1,500 motorists drove 105,000 miles and posted and shared 528 road alerts in the last week alone. Of course, a system based on collecting data from users’ posts works better when more people take part, so if the number is smaller, it might not always be 100% reliable. 5.4. National emergency services spring to mind first when one thinks of the users of the more precise, dynamically-updated maps which are currently available.

While new interaction technologies are making maps richer, there is still one underlying theme uniting all maps throughout history – location. We’ll always need to know where we are.
