Adjust the vertices if needed using the # Line/Polygon Edit Controls. # Description: # This Tool Script has four different modes that the geologist can use: # ADD - While viewing the reference image, place 3 points (three vertices of a # triangle) on a bedding plane by left clicking on the screen using the # provided polygon tool. # Assumptions: # The DEM is the bottom layer in the active group. The script creates # and displays a dialog to show the computed attitude values and allow # designation of overturned beds.
The script creates two # vector objects: a StrikeDipVector to store point elements with attached # attitude values in the associated point database, and an OutcropTrace # object to store outcrop traces for each point (see below). The accompanying CartoScript displays the added # points using the appropriate attitude symbols. # Version 24 March 2008 # Fixes a problem with the user-defined function to return angle to north # that is used to correct the strike azimuth # Purpose: # The purpose of this Tool Script is to give a geologist a streamlined method # for determining the Strike and Dip values from an accurate DEM raster and # overlaid arial imagery. # Strike azimuth and dip direction are automatically adjusted for the local # grid angle to north at each point. # Automatically applies raster scale value to allow scaled DEMs with values in feet or decimeters. 2007 # Requires TNTmips 2007:73 or later # Revisions: # Produces correct attitude values for DEMs with geographic coordinates by # using appropriate UTM zone coordinates for attitude computations. # Authors: # Dave Breitwisch # Randy Smith # Dan Glasser # Version Nov.
