I need a simple understanding of nontopological geometry.
I am completely new in this area so please correct me if I am wrong.
As far as I understand in topological geometry the object(say a line) can be bend but in nontopological geometry object can be only be moved but can not be changed in a new shape.
I came to know about nontopological geometry while reading a documentation about afrigis mapserver. Here is a little from the documentation where I found the term nontopological which may have its source the ESRI Shapefile Technical Description (page 1).
A shapefile stores nontopological geometry and attribute information for the spatial features in a data set. The geometry for a feature is stored as a shape comprising a set of vector coordinates. Because shapefiles do not have the processing overhead of a topological data structure, they have advantages over other data sources such as faster drawing speed and edit ability
