Displaying Geographic Data on an Image Taken at an Oblique Angle

Systems and methods for displaying geographic data on an image taken at an oblique angle are presented. In order to efficiently allow a user computer to map geographic data on an image taken at an oblique angle, an online source, such as an online image source, provides metadata in conjunction with the image. The metadata includes a projection matrix, approximate elevations information, and a depth bitmap. Upon receipt of the image and metadata, and in displaying the geographic data on the image, an approximate elevation for a given coordinate pair (latitude and longitude) is determined according to the approximate elevations information and a determination as to whether the particular element of geographic data is occluded is determined according to a corresponding depth value in the depth bitmap of the metadata.
