Rendering vector maps is a key challenge for high-quality geographic visualization systems. In this paper, we present a novel approach to visualize vector maps over detailed terrain models in a pixel-precise way. Our method proposes a deferred line rendering technique to display vector maps directly in a screen-space shading stage over the 3D terrain visualization. Due to the absence of traditional geometric polygonal rendering, our algorithm is able to outperform conventional vector map rendering algorithms for geographic information systems, and supports advanced line anti-aliasing as well as slope distortion correction. Furthermore, our deferred line rendering enables interactively customizable advanced vector styling methods as well as a tool for interactive pixel-based editing operations.
