A graph is a way of representing connections between places. Mathematically, a graph is a collection of nodes and edges. Nodes are locations that are connected together by the edges of the graph. I need graph data for the city of Hickory, North Carolina. How can I have/buy those data ? Please provide links where I can buy for reasonable prices. I need this for my project. | |

Actually a graph is a diagram (as a series of one or more points, lines, line segments, curves, or areas) that represents the variation of a variable in comparison with that of one or more other variables. The question is what variables are you interested in? Do you want the distance between buildings? Street Intersections? What? |

Streets and intersections are good, and enough for my project. But, if there is more complete data (between buildings) for the same price, it would be great. |

I think the information you're requesting may be impossibly large. A list of the distances between each interesection and all other intersections would be huge. Hickory appears small, but I think if you included buildings the list would be impossibly huge. The best I can come up for you is this: http://www.wpcog.org/hickorygis It's not a list, but it is a zoomable map that contains a lot of info. If you need distances between certain addresses or intersections and they aren't "as the crow flies" I'd use google maps. |
