Abstract
Embodiments render polygonal data in a geographical information systems according to a viewing perspective of a geographical information systems user. The user may define a viewing perspective. A bounding box may be determined that includes the area being viewed in the viewing perspective. A spherical coordinate to Cartesian coordinate matrix may be determined to approximately convert spherical coordinates of the polygonal data to Cartesian coordinates to be rendered by a graphics processor. The graphics processor may then render the polygonal data and bias detail towards the viewing perspective of the user.
