1. A computer-implemented method for generating information based on perspectives of a three-dimensional scene comprising: (6) (4)

obtaining a first two-dimensional view point representation of a first location point in the three-dimensional scene based on a sensor model representation, wherein the sensor model representation is generated using a sensor system having a perspective external to the first location point; and

determining, with a processor-based computing device, a data representation from the first two-dimensional view point representation without finding three-dimensional coordinates of the first location point, wherein the determining the data representation includes deriving from the first two-dimensional view point representation a second two-dimensional view point representation from a second perspective external to the first location point;

deriving, with the processor-based computing device, a distance measurement value between the first location point and a second location point in the three-dimensional scene; and

inserting, with the processor-based computing device, the data representation and the distance measurement value into one of the first and second two-dimensional view point representations.
