The claimed subject matter relates to a computer-implemented architecture that can generate a map. The map can be a hybrid between an orthographic projection map and street-side images, thus including useful aspects from both types of representations. For example, an orthographic projection map is very effective at presenting global relationships among the features of the map, but not effective at presenting local detail. In contrast, street-side images show excellent detail, but do not convey the global information of an orthographic projection map. The hybrid map can thus provide a richer set of information than conventional maps, and can also display objects / features of the hybrid map in multiple perspectives simultaneously on a single representation that is printable.
