Gaaffii 1

Which of the following is an example of a discrete object with well-defined boundaries?

  1. A.Elevation
  2. B.A lake
  3. C.Air temperature
  4. D.Atmospheric pressure
Deebii fi sababa agarsiisi

Deebii: B A lake

Sababa

A discrete object has clear, definable boundaries where it begins and ends. The textbook gives a lake as an example of a discrete object within a landscape.

Gaaffii 2

How many satellites orbiting the Earth must a GPS receiver connect with to calculate a precise location?

  1. A.One or more
  2. B.Two or more
  3. C.Four or more
  4. D.Ten or more
Deebii fi sababa agarsiisi

Deebii: C Four or more

Sababa

A GPS receiver needs to connect with four or more satellites orbiting the Earth as a reference to calculate the user's location within a few meters.

Gaaffii 3

In geographic data representation, which of the following is classified as a point feature?

  1. A.A water well
  2. B.A paved highway
  3. C.A river channel
  4. D.A forest stand
Deebii fi sababa agarsiisi

Deebii: A A water well

Sababa

Point data exists when a feature is associated with a single location in space. Examples given in the textbook include water wells, telephone network towers, and weather stations.

Gaaffii 4

Which graphical tool is best designed to show how a whole total is divided into percentage categories?

  1. A.Line graph
  2. B.Bar graph
  3. C.Pie chart
  4. D.Topographic map
Deebii fi sababa agarsiisi

Deebii: C Pie chart

Sababa

A pie chart is designed to visualize how a whole is divided into various parts, representing a percentage distribution of the dataset.

Gaaffii 5

In the data lifecycle, which stage involves quality assurance (QA), quality control (QC), and merging duplicate variables?

  1. A.Data collection
  2. B.Data processing
  3. C.Data analysis
  4. D.Data dissemination
Deebii fi sababa agarsiisi

Deebii: B Data processing

Sababa

The second stage of the data lifecycle is data processing, which includes checking data quality (QA/QC), merging duplicate variables, and appending new information.

Gaaffii 6

According to the textbook, what is the main difference between data and information?

  1. A.Data is processed output, while information is raw input.
  2. B.Data consists of unprocessed facts, while information is processed data.
  3. C.Data always depends on information, while information is independent.
  4. D.Data is only stored on paper, while information is stored on computers.
Deebii fi sababa agarsiisi

Deebii: B Data consists of unprocessed facts, while information is processed data.

Sababa

Data refers to unprocessed facts or figures used as input, while information is the processed, organized result that adds meaning to the receiver.

Gaaffii 7

In a vector data model, what is the term for a vertex that starts or ends an arc (line) segment?

  1. A.Cell
  2. B.Polygon
  3. C.Node
  4. D.Pixel
Deebii fi sababa agarsiisi

Deebii: C Node

Sababa

In vector data, linear features (arcs) consist of a string of vertices terminated by a node, which is the vertex that starts or ends the line segment.

Gaaffii 8

Which of the following is an example of directly collected geographic data?

  1. A.A temperature reading taken at a local weather station
  2. B.A satellite image downloaded from the internet
  3. C.An aerial photograph taken by an airplane
  4. D.A scanned analogue map
Deebii fi sababa agarsiisi

Deebii: A A temperature reading taken at a local weather station

Sababa

Directly collected data is generated at the source of the phenomena, such as visiting a weather station to record temperature readings or counting trees on a farm.

Gaaffii 9

Which spatial data model represents geographic features using a grid-cell structure organized into rows and columns?

  1. A.Vector data model
  2. B.Raster data model
  3. C.Aspatial data model
  4. D.Polygon coordinate model
Deebii fi sababa agarsiisi

Deebii: B Raster data model

Sababa

Raster data models use a grid-cell structure where the area is divided into cells identified by rows and columns.

Gaaffii 10

Why can the element of time be safely omitted when mapping elevation on the Earth's surface for most applications?

  1. A.Elevation changes occur very slowly over hundreds or thousands of years.
  2. B.Elevation has no spatial coordinates on the Earth's surface.
  3. C.Elevation data cannot be represented in a digital GIS database.
  4. D.Elevation changes rapidly every hour like air temperature.
Deebii fi sababa agarsiisi

Deebii: A Elevation changes occur very slowly over hundreds or thousands of years.

Sababa

Processes that change land height, such as erosion and crustal movements, operate over hundreds or thousands of years. Therefore, time is slow to change and can be safely omitted for elevation representation.
