Vector Data Model

To prepare spatial data for computer processing, the

vector data model first uses points and their x-, ycoordinates

to represent spatial features as points, lines,

and areas. Then it organizes geometric objects and their

spatial relationships into digital data files that the computer

can access, interpret, and process.

Simple Features

The vector data model uses the geometric

objects of point, line, and area to represent

simple spatial features

Topology

Topology is the study of those properties of geometric

objects that remain invariant under certain transformations

such as bending or stretching.

Diagrams or graphs are used in topology for studying

the arrangements of geometric objects and the

relationships between objects.

TIGER

An early application of topology in geospatial

technology is the TIGER (Topologically Integrated

Geographic Encoding and Referencing) database

from the U.S. Census Bureau.

綜合上述:整理地圖學、G.I.S.重要名詞，令不僅止於測量與空間資訊組的學生，也能瞭解其中的知識，並發現地圖學與G.I.S乃是相輔相成的，儘管分開成為不同學科，但是仍舊可以予以整合!諸如:就讀土地管理的宸凱，瞭解其知識運用於國科會計畫…
