How To Draw A Geological Cross Section
Begin by choosing two points that define a cross section profile of interest.
How to draw a geological cross section. Set minimum z value to 0 as we will need space for geological interpretation. Put a strip of paper along the cross section and make a mark on your paper wherever the contour lines intersect with your paper. Now you can draw simple profile based on your section location and elevation data from dem.
Decide what the geologic cross section is going to be used for and use this to guide you in selecting the appropriate. Label these points as a and a. Draw a cross section line on your map you can also import it as shapefile in place where you would like to model the geology.
These should be selected so that a line between them will be approximately perpendicular to the strike directions of the intervening rock units. On the map locate the well or borehole positions land service elevations depth of the well and the number of geologic. Choose appropriate vertical and horizontal scales.
