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. |

1. A method for determining a viewable point of interest from a vantage point, the method comprising:
receiving, by one or more processors, a three dimensional map of a designated area, that includes location data and relative height data of one or more vantage points, one or more points of interest, and one or more objects, within the designated area, wherein each height of the one or more vantage points, the one or more points of interest, and the one or more objects, is relative to heights of other one or more vantage points, one or more points of interest, and one or more objects, within the designated area; determining, by one or more processors, a line-of-sight view from the one or more vantage points to the one or more points of interest within the designated area, 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; determining, by one or more processors, whether the line-of-sight view between the one or more vantage points and the one or more points of interest are obstructed, based on the line-of-sight view, the location data, and the relative height data, of the one or more vantage points, the one or more points of interest, and the objects, within the designated area; and responsive to determining that the line-of-sight view is free of obstruction, one or more processors identifying each of the one or more points of interest that are viewable from each of the one or more vantage points, within the designated area. |
