A three dimensional map of a designated area that includes location data and relative height data of vantage points, points of interest, and objects, within the designated area, is received. A line-of-sight view from the vantage points to the points of interest is determined by calculating an angle, a distance, and a direction between a vantage point and a point of interest based, at least in part, on the location data and relative height data associated with the three dimensional map of the designated area. Obstructions of the line-of-sight view between the vantage points and the points of interest are determined, based on the line-of-sight view, the location data, and the relative height data, and responsive to determining that the line-of-sight view is free of obstruction, identifying each point of interest viewable from each vantage points, within the designated area.
