The vector stencils library "3D directional maps" contains 40 symbols for creating pictorial maps, street maps, locator maps, transit maps, tourist maps with points of interest (POI), road maps and route maps using the ConceptDraw PRO diagramming and vector drawing software.
"Pictorial maps are a category of maps that are also loosely called illustrated maps, panoramic maps, perspective maps, bird’s-eye view maps and Geopictorial maps amongst others. In contrast to the regular road map, Atlas or topographic cartography, pictorial maps depict a given territory with a more artistic rather than technical style. The cartography can be a sophisticated 3-D perspective landscape or a simple map graphic enlivened with illustrations of buildings, people and animals. They can feature all sorts of varied topics like historical events, legendary figures or local agricultural products and cover anything from an entire continent to a college campus. ...
Pictorial maps usually show an area as if viewed from above at an oblique angle. They are not generally drawn to scale in order to show street patterns, individual buildings, and major landscape features in perspective. While regular maps focus on the accurate rendition of distances, pictorial maps enhance landmarks and often incorporate a complex interplay of different scales into one image in order to give the viewer a more familiar sense of recognition."

The design elements library "3D directional maps" is included in the Directional Maps solution from the Maps area of ConceptDraw Solution Park.
