Abstract
Embodiments relate to navigating along a street network in a geographic information system. In an embodiment, a computer-implemented method navigates a virtual camera in a three-dimensional environment at street-level. The virtual camera defines a perspective to display the three-dimensional environment. In the method, a target location is determined in the three-dimensional environment. A path along a representation of a street in the three-dimensional environment is determined. The path is from a first position corresponding to an initial location of the virtual camera to a second position corresponding to the target location. A virtual camera is moved in the three-dimensional environment toward the target location along the path. Finally, the virtual camera is oriented to face the target location as the virtual camera moves along the path.
