===Stratigraphic applications===

For stratigraphic applications, comparisons to a set of models is also a valid interpretation approach, but in this case, very simple models do not work well. Sedimentary geology is too complex. In fact, hand-drawn models may not be valid at all. It is preferable to use independently verified field examples, such as the one shown in [[:file:dipmeters_fig7.png|Figure 7]]. In this example, the sandy sediments are made up of a sequence of interrupted, truncated, and stacked point [http://geonames.usgs.gov/apex/f?p=136:8:0::::: bars] deposited by meandering stream activity. Few complete fining-upward point bar cycles (gravels to sands to shales) are present. Instead, erosional cuts and festoon cross-bedding indicate the start of a new cycle that may or may not be interrupted before the deposition of low angle planar current bedding. (Additional characteristics of meandering streams are covered in  [[Lithofacies and environmental analysis of clastic depositional systems]].) In the general case, a catalog of field examples of dip plots from various known depositional environments is a valuable aid to stratigraphic dipmeter interpretation.
