dc.descriptionAbstract: Conifer tree influence on the collection and portrayal of Digital Terrain Elevation Data (DTED) is presented. Study sites are investigated which had dense conifer canopy closure. Two separate DTED collection techniques are examined in the context of studying conifer tree influence: (1) photo source auto-correlated, and (2) photo source operator assisted (floating dot). Field surveying is the mechanism used for collecting accurate, verifiable ground elevation data subsequently compared against the elevations of corresponding DTED positions. Estimated conifer tree stand heights (at the time of DTED photo source) are compared against the difference in value between DTED and field surveyed elevations. A close relationship between stand height and difference values demonstrates the potential for conifer tree height inclusion within DTED1ground elevations. Terrain modelling impacts caused by the addition of tree heights within the DTED are addressed.-
