Lab 3
View Delicious Food Under $15 a Plate in LA County in a larger map
The evolution of web 2.0 has made geography a major aspect of the lay man’s everyday life. From the ability to use GPS to get from one place to another while simultaneously having the ability to see gas stations and food stops on the desired route. One is also able to see the exact route through geographic imaging such as images on Google maps taken by both satellite as well as street view images taken by Google’s street image vehicles. Through these imaging options one may see the exact destination before one even leaves the house.
While neogeography makes geographic systems more accessible to the general public through systems such as Google maps, one must by wary of the information supplied on the Internet. Since a great deal of information is supplied via volunteer sources, there is little to no incentive to supply information that is completely reliable. If the information has not been updated recently it may no longer be relevant. For example, construction may have altered the available routes. Faulty information may lead one to be lost.
The easy accessibility of GPS in one’s car can lead to danger as a result of split attention between the GPS device and the road. Also, false information on the GPS can be dangerous as confusion concerning discrepancies between the GPS and the reality of the road can divert attention from the dangers of the road.
