Description: The Perspective View Generator (PVG) is a database driven simulation that displays a three      dimensional synthetic environment from terrain information stored in a two dimensional array.      Each terrain element is identified by coordinates which index the array. Each array value      contains 32 bits of information arranged to specify the greyshade, elevation and other features      of the terrain at that position. Currently there are few areas of the world digitally mapped in the      data format accepted by the PVG. The objective of this thesis is to enable the automatic      generation of a database for use with the PVG from information available from various      sources. The project involves writing computer algorithms to synthesize data from different      sources and making modifications to the PVG functions. The source of terrain information is      aerial imagery and elevation information which is not resolved fine enough to distinguish tree      and building heights. The ability to modify the data base to include object heights allows the      PVG to show the target masking effects these objects have in a given region. The resulting      synthetic environment can be used for strike planning and as a mission tailored training tool.
