* At convenient times, the fracture data should be plotted in preliminary form on either [ht tp://www.answers.com/topic/rose-diagramrose diagrams] or [facstaff.uww.edu/bhattacj/geolgy318_presentation_2.ppt pole plots (π diagrams)]. Such preliminary plotting is necessary in the field to establish trends and application to simple geological fracture models. In this way, working interpretive models can be created and altered or updated while field data are still being gathered. The observer should always examine fracture patterns in light of their relationship to their localities and to local structural configuration.

* The number and frequency or spacing of quantitative measurement stations are generally high in the early stages of study in a region and decrease in relationship to qualitative stations throughout the study.

* When dealing with outcrops containing a predominance of either contractional fractures or fractures related to [[unconformity]] surfaces,<ref name=pt06r95 /> much of the previous quantitative orientation data will be ill-defined due to their [http://www.merriam-webster.com/dictionary/isotropic isotropic] or irregular distribution in orientation. In these outcrops, matrix block size (fracture spacing in three dimensions) are very important, as are lateral distribution and lithology.
