Discrete Spatial variables
1.5. 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 1 . 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.
1 Regionalization can be defined as: "The process of generalizing properties of a phenomenon throughout space, based on a set of
observations". This definition is common to both continuous and discrete spatial distributions.
