Panoramic imagery of a geographic area can be captured by mobile data acquisition units from a perspective at or near ground level. This imagery can be a valuable resource for refining representations of a geographic area provided, for instance, by a geographic information system, such as a mapping service or a virtual globe. For example, panoramic imagery can be used to refine or generate high resolution three-dimensional models of various landmarks, buildings, objects, terrain, etc. in a geographic information system. The panoramic imagery can also be used to provide interactive three-dimensional imagery of a geographic area from a street or ground level. The panoramic imagery can have associated camera parameters, such as an image pose, and geometry information regarding the geographic area depicted in the imagery.
Panoramic imagery can be stored in a geographic information system database. Geographic information system databases can also store aerial imagery of a geographic area. The aerial imagery can be captured, for instance, from an aircraft and can provide, for instance, an oblique perspective of the geographic area from one of various canonical viewpoints, such as north, south, east, and west canonical viewpoints. The database of aerial imagery can be associated with pose information. Additionally, the database of aerial imagery can have an associated three-dimensional geometry of the subject matter depicted in the imagery.
