1. A computer implemented method to detect a presence in an area of study of a ground-level object, the method comprising: gathering, in a processing device, a point cloud of three-dimensional imaging data representing the area of study from an aerial position where an intervening obstacle impedes a line of sight between the aerial position and a ground-level object; processing, in the processing device, the three-dimensional imaging data to identify elements in the point cloud having common attributes signifying that the identified elements correspond to a feature in the area of study that is at least partially obscured by the intervening obstacle; generating, in the processing device, at least one implied geometrical representation which represents data points having equivalent scalar values as calculated from the collected data; generating, in the processing device, at least one isosurface associating the elements having common attributes; selecting, in the processing device, a region of interest from the area of study; generating, in the processing device, from the imaging data gathered from the aerial position an up from underground oriented visualization model of the region of interest; and displaying, on a display module coupled to the processing device, the up from underground oriented visualization model to expose the feature in the area of study that is at least partially obscured by the intervening obstacle in the line of sight between the aerial position and the ground-level object.
