An apparatus (10) is disclosed for determining, in a first speed mode of operation, speed and range of a moving object and, in a second survey mode of operation, determining direct distances to an object and automatically calculate horizontal and vertical component distances to the object. Also disclosed are a system and method for data entry and retroactive reconstruction of the relative position of features and objects, in particular with respect to scenes such as transitory occurrences, utilizing a signal transmitting and receiving speed, distance and tilt angle determining apparatus or device. In a particular embodiment, the apparatus (10) disclosed has special applicability to tactical situation use by law enforcement personnel and the system and method in the on-scene recordation and subsequent ex post facto reconstruction of crime and traffic accident scenes by law enforcement officers. The system and method may be readily and efficiently implemented in conjunction with a laser-based speed, distance and tilt angle determining device otherwise usable for vehicle speed traffic monitoring functions utilizing either triangulation (100) or baseline/offset (10) mensuration techniques.
