Regionalization
This unit will introduce how to delineate or define a boundary of a spatial object (non pre-existed) and assign a value (nominal, ordinal and ratio) to it or label a pre-existed spatial object Such as your farm based on point sample measurements of particular phenomena, such as soil texture and assign a value or
label, such as sandy clay loam to your farm through the process of 
regionalization. At the end of the unit, you will learn how to assign or label the spatial objects (pre-existed or non pre-existed) using
the regionalization concept. When the spatial distribution of phenomenon properties is assumed as discontinuous, it is important
to consider several situations for assigning properties to features. Most of the time properties of a phenomenon are measured
at specific locations (measurement sites). This set of data is called sample. From these point feature measurements thematic
properties should be assigned to a set of spatial features.

Learning Objectives
The following two complementary objectives will be accomplished during this unit of study:
- To derive spatial features from the spatial distribution of measured properties: This process of object construction is called regionalization in the strictest sense.
- To assign a global thematic property to each spatial object from a pre-existing set, based on sample data: This process is called thematic allocation or labelling and can be considered as part of the regionalization.
