A bog or muskeg is acidic peat land (peat bog).
A moor was originally the same as a bog but has come to be associated with this soil type on hill-tops.
Classification
Classification is the procedure of identifying a set of features as belonging to a group and defining patterns. Some form of classification function is provided in every GIS.
Class - Subdivision of a phylum containing a group of related orders.

Location based Services can be classified according to various categorisations. One is by their class of application: trigger services, tracking & monitoring, location-based information and assistance services.
The classes essentially represent types or templates. The objects are concrete values corresponding to the type (template) of the class from which are instantiated.
Soil classification systems have been created to provide scientists and resource managers with a system to determine the charateristics of a soil in a particular location. Several different classification systems exist.
We can classify patterns on hyperbolic cloth. We can look for hyperbolic mirrors, hyperbolic gyration points, etc. and analyze hyperbolic cloth just as we analyzed Euclidean cloth.
