1. Spatial data describe
what geographical features are
geometry of geographical features
both location and attribute of geographical features
where geographical features are located
2. Within the context of GIS, the term "spatial data"refers to data that has:
Positional Values
Graphic Values
Decimal Values
Complex Values
3. Describe the significance of the TIGER system in the context of GIS.
The TIGER system is primarily used for satellite imagery processing.
The TIGER system focuses on raster data management exclusively.
The TIGER system is a software application for GIS visualization.
The TIGER system provides a framework for encoding geographic
data in a topologically integrated manner, which enhances spatial
analysis.
4. Describe the role of feature classes in organizing spatial data within GIS.
, Feature classes are primarily concerned with the analysis of temporal
data.
Feature classes represent the physical hardware used in GIS.
Feature classes are used to convert raster data into vector data.
Feature classes help organize spatial data by grouping similar
objects, such as roads or rivers, into a structured format.
5. What format does a Digital Elevation Model (DEM) use to represent terrain
relief?
3D format
Raster format
Vector format
Tabular format
6. What is the difference between discrete and continuous data sets?
Discrete are objects with specific locations or boundaries,
continuous represent quantities that may be measured anywhere on
earth
There is no difference
Discrete are geo-referenced while continuous are not
Discrete are 2 dimensional, continuous are 3 dimensional
7. Describe how a network in GIS topology differs from other forms of
topology.
A network in GIS topology does not involve any relationships between
nodes.
A network in GIS topology is characterized by directed relationships
between nodes, unlike other topologies that may not require
, directionality.
A network in GIS topology is the same as a raster data model.
A network in GIS topology is simpler and only includes non-directional
relationships.
8. Which of the following about network analysis is not true?
Lines must have direction
Turns have to be defined
Neither an overpass nor an underpass can be represented in a GIS
database
A network is typically topological based
9. What is the primary type of data that a raster model is designed to store?
Topological data
Continuous data
Discrete data
Vector data
10. In a GIS project, if you were to implement an object-based model, what
advantage would you expect in managing spatial data?
Improved data management through integrated spatial data and
attributes.
Limited ability to represent complex spatial relationships.
Reduced accuracy in spatial analysis.
Increased complexity in data retrieval processes.
11. Discuss the contributions of Roger Tomlinson to the field of Geographic
Information Systems.
