GPS accuracy Several factors have an impact on the deviation between your real position and the one given by the GPS device. For example, signal delay in the ionosphere or reflecting objects near the GPS device have a different and varying impact on how accurately the GPS device can calculate your position. Map Asus GO works with digital maps which are not simply the computerised versions of traditional paper maps. Similarly to the paper road maps, the 2D mode of digital maps show you streets and roads. In 3D mode, you can also see the height differences, for example valleys and mountains, or buildings. Digital maps, however, differ from paper maps in that you can use them interactively: you can zoom in and out (increase or decrease the scale), you can tilt them up and down, turn them left and right. In GPS-supported navigation, digital maps facilitate route planning. Route Can contain one or more via points. The last via point is the destination and the route is cut into different legs (from one via point to another). Scheme Asus GO comes with different colour schemes for the map for the daylight or night use. Schemes are custom graphic settings for the map and they can have different colours for streets, blocks or surface waters in 2D and 3D modes, and they display shades or shadows in different ways in 3D mode. 69
