For linear structures and for planar structures in outcrops of low tectonic dip only the azimuth need be recorded. The orientation of the structures will be recorded, including both the azimuth and dip of planar structures that need correction. If it is excessive (greater than about 10~ each measurement must be corrected on a stereographic net. At each station it is necessary to record structural dip and strike. Thus each sample station will also be the location of a measured section, or at least some detailed notes on stratigraphy, lithology, facies, and fauna. If it is to be worth anything, paleocurrent analysis must be integrated with a full sedimentological study. Each sample station will generally consist of a cliff, quarry, stream section, road cut, etc.
