In order to represent the spatial information and their attributes, a data
model-a set of logical definitions or rules of characterizing the is
adopted.
Geological data Tabular data

The operation is similar to the point-in-polygon overlay,
with that obvious exception that a line layer is used instead of a point input
layer.
Line-in-polygon Polygon-in-polygon
Area-in-polygon Intersection
Single layer operation is also known
Vertical operation Overlay operation
Horizontal operation Spatial operation
is first time designed by Peuker.

To build a new object or objects by identifying all areas that are within a
certain specified distance of the original objects is called
