Abstract:
One or more systems, devices, and/or methods for organizing spatial data are disclosed. For example, a method includes receiving a location data point from a navigation device. A controller compares the distance from each of a plurality of data points to the location data point. In constructing a depthmap that associates each of the data points with the distance from the location data point, the controller assign data points within a minimum distance from the location data point into a first cell and data points greater than the minimum distance from the location data point into a second cell. The second cell is larger than the first cell and corresponds to a larger geographic area than the first cell. The depthmap may be configured to position points of interest in a panoramic or street level view image.
