In general, we all have experience of paper travel maps or
electronic maps as found in Google
Maps™ or Google Earth™ . Unlike
paper maps, electronic maps provide the ability to display the
data you need, the way you need it.
There are three main categories of map:
- Vectorial maps are a set of points, lines or areas and can contain additional data such as road names. You can decide on the look and feel of the display.
- Raster maps as satellite views. These provide realistic views of the earth, but are often heavy and can be confusing.
- Elevation maps that provide altitude information for any place on the globe.
All three categories can be mixed together
in a single map display.
