Dakota - 3D Visualization Services

High resolution GIS imagery and traditional basemap features, such as CAD drawings, topographic maps, or aerial photographs, may be combined to represent the ground surface in three dimensions, with the photographs or maps precisely placed on the topographic surface. The three-dimensional models may then incorporate lithologic information from boring logs, as well as analytical results from soil and groundwater samples. The synthesis of this information into an interactive database visualization tool allows the distribution of contaminants to be clearly shown within the hydrogeologic frame-work and can be used to demonstrate how the various media interact in the subsurface.

TarGOST/UVOST/DyeLIF/MIP/HPT data logs are typically acquired at 1 inch or less vertical resolution, which is orders of magnitude higher resolution than traditional sampling methods. Dakota`s key advantage is high accuracy in the contamination models. When visualized in 3-D, contaminants migrating in narrow seams of sand, silt, or gravel are easy to see. The high data density of LIF reveals these types of contaminant distribution features often missed by conventional methods. Dakota`s interpolation algorithms combined with the high density LIF data produce a high correlation between individual LIF data logs and the 3-D source term model.
