To get a good spatial idea of the sampling one needs to locate the samples and sections.
Usually, one locates the top of the section, and then the samples are automatically located by their position in the section, as long as we sample in the section vertically.
If we are not sampling vertically in a section, that is the section is not vertical then we need to capture at least a point in the direction the section runs, in addition to the position of the top of the section.
