Abstract
The present invention discloses a method, apparatus, and article of manufacture for a computer implemented geographic information system that enables viewing a map picture that is generated from vector-based data. Map pictures can be generated with vector-based data. Map pictures created with vector-based data can be viewed. Additionally, map pictures are comprised of map objects, such as states and cities. Map objects can be chosen to obtain additional information, for example, a different map picture. Additionally, areas of the map picture can be zoomed in on to view the areas with greater resolution or to obtain additional data about the areas. Furthermore, when a user requests to view a map picture, only the map data required to respond to the user'"'"'s request is downloaded to generate a map picture. As a user makes additional requests for information, additional map data is downloaded and new map pictures generated.
