INFORMATION PROCESSING DEVICE, METHOD, AND PROGRAM

According to one aspect, an information processing apparatus includes: a terrain data processing unit which performs a terrain data process of calculating a terrain coordinate group based on terrain data in which a position and a shape of an object are represented by a plurality of nodes or are represented by a plurality of nodes and a link between the nodes; and a selection processing unit which selects nodes adjacent or close to each other, indicated by the terrain coordinate group calculated by the terrain data processing unit, and selects a node suitable to calculate a width of the object from other nodes based on a positional relationship between the selected nodes and the other nodes.
