【 摘 要 】

Cross-section can be described as a two dimensional dataset where the horizontaldistances are represented on the x-axis and the depth on the y-axis. A cross-sectionis a window into the subsurface. This work presents the construction of crosssections with the help of 'Vigat 2005' - a Visual C ++ based software application.Its main purpose is to provide cross section views of geoscientific featuresand to interpret their variation within the area of study. In geological context,profile or cross section is an exposure of the ground showing depositional strata.Geological cross sections are very powerful means of conveying structural geometries.They are planar, usually vertical, graphical representations of earth sectionsshowing stratigraphical successions, age, structure, and rock types presentin the subsurface. Geological cross sections allow a better conceptualizationof the 3-D geometry of the structures. By using 'Vigat 2005', a cross sectiongraphic can be displayed by the user with a simple click of the mouse. It offersmuch easy to use functionality to facilitate the completion of desired tasks.Specific boundary conditions to represent the movement of rock block over thefault can be displayed using the graphical user interface. Relief or slope variationof the study area can also be viewed. A topographical map provides an aerial(overhead) view of a landscape. It is possible to create a more pictorial representationof the landscape by making a topographic profile of the region. A topographicprofile is a cross section showing elevations and slopes along a given line.A precise method to determine slope variations is to construct a profile orcross section through the topography. The most important advantage of 'Vigat2005' is that users do not need to digitize contours. This work focuses on thedesign and implementation of an optimized interpretive environment that havebeen built using Visual C++ tools. Strong programming capabilities of VisualC++ have been utilized, at its full extent, for the development of 'Vigat 2005'.
