Methods and apparatus for a map tool displaying a three-dimensional view of a map based on a three-dimensional model of the surrounding environment. The three-dimensional map view of a map may be based on a model constructed from multiple data sets, where the multiple data sets include mapping information for an overlapping area of the map displayed in the map view. For example, one data set may include two-dimensional data including object footprints, where the object footprints may be extruded into a three-dimensional object based on data from a data set composed of three-dimensional data. In this example, the three-dimensional data may include height information that corresponds to the two-dimensional object, where the height may be obtained by correlating the location of the two-dimensional object within the three-dimensional data. |
