Question
Topology is:
The surficial features of the earth
The attributes of features on a map
The study of mountains
The spatial relationship between features on a map
The process of graphically representing points
Match the topological characteristic to the most appropriate answer
adjacency
connectivity
planar topology
polygon topology
Choices are: right & left sides, line network, non-overlapping polygons, inclusions and connected polygons
Select the following statements that are true about a GIS database:
Different types of thematic data can be combined in one layer of a GIS database.
Thematic layers organize spatial and attribute data
Data from different thematic layers are combined through analysis
Real world data is represented as separate thematic layers
Which of the following is true about a line feature?
A line feature is made of line segments (arcs).
The shape of a line is defined by arcs connected by vertices.
A line connects two end points (nodes).
All of these statements
Linear features must connect back to their starting node.
Explanation / Answer
1 answer: The spatial relationship between features on a map
Explanation: Topology is used in the context of a digital representation of spatial data in two dimensions, pertains to the relationships among feature geometry objects such as points, lines and polygons on maps. The temporal relationships between units, structures and events within a geological model can also be considered as part of its topology.

2 answer: adjacency = Left-right topology
connectivity = line network
planar topology = non-overlapping polygons
polygon topology = inclusions and connected polygons
3 answer: Different types of thematic data can be combined in one layer of a GIS database.
Thematic layers organize spatial and attribute data
Data from different thematic layers are combined through analysis
Real world data is represented as separate thematic layers
all the above statments are true about the GIS database. In Arc GIS differet thematic layes are used to represent the different real world features like roads, areas. point features. and different thematic layes are used in GIS for for seperate real world data so it could be easy to undestand and easy handle.
4 answer: A line feature is made of line segments (arcs).
The shape of a line is defined by arcs connected by vertices.
A line connects two end points (nodes).
all the above statement is correct about the line feature. Line feature is udes to represent the road networks in the maps. which is composed of nods and arc which we called as vertics. The has tow nodes start nods and end nod but it is not compulsory that the linear feature must be connected to it's start point.
