1. A system to generate a three-dimensional oblique aerial map view, comprising:

  • one or more processors;

    a non-transitory computer readable storage medium comprising instructions, that when executed by the one or more processors, cause the one or more processors to;

    receive distance data to points in a street-level scene and panorama images that include the street-level scene, the distance data sensed using a LIDAR scanning system and the panorama images captured using an image-capture system;

    responsive to a determination that a first scan data point in the distance data has a missing pixel value in the panorama images;

    interpolate a pixel value for the missing pixel value based at least on pixel data of the panorama images that correspond to scan data points adjacent in location to the first scan data point;

    substitute the interpolated pixel value for the missing pixel value;

    distributively process the distance data and the panorama images using distributed computing nodes, each computing node configured to process an arbitrary set of the panorama images into image tiles and the distance data into associated depth maps of specified orthographic projections;

    merge two or more partial renderings of an image tile of a same area into a single rendering of the image tile using z-buffer values of associated depth maps by retaining pixel values in the two or more partial renderings that have a highest z-buffer value of the associated depth maps, each of the two or more partial renderings of the image tiles rendered independently from different panorama images; and

    generate a three-dimensional oblique aerial viewpoint based on the image tiles.
