Pattern detection via the identification of such geographical clusters is a very simple and generic form of geographical analysis that has many applications in many different contexts. The emphasis is on localized clustering or patterning because this may well contain the most useful information.
[1] [2] It may fill the core of a wall which is faced with unit masonry such as brick or ashlar. Some medieval cathedral walls have outer shells of ashlar with an inner backfill of mortarless rubble and dirt.
Two adjacent vermiculated blocks showing rather different interpretations of the pattern.

Regional geography is also a certain approach to geographical study, comparable to quantitative geography or critical geography. This approach prevailed during the second half of the 19th century and the first half of the 20th century, a period when then regional geography paradigm was central within the geographical sciences.
