  1. Adobe Photoshop

  2. Microsoft Word

  3. Google Earth

  4. ArcGIS


Correct Option: D
Explanation:

ArcGIS is a widely used software suite for creating, editing, and analyzing digital maps. It provides a comprehensive set of tools for geospatial data management, mapping, and analysis.

What is the term used to describe the process of converting analog maps into digital format?

  1. Digitizing

  2. Vectorization

  3. Rasterization

  4. Geocoding


Correct Option: A
Explanation:

Digitizing is the process of converting analog maps into digital format by tracing the features on the map using a digitizing tablet or other input device.

Which type of digital map data structure stores features as a collection of points, lines, and polygons?

  1. Raster

  2. Vector

  3. Topological

  4. TIN


Correct Option: B
Explanation:

Vector data structures store features as a collection of points, lines, and polygons. This format allows for precise representation of geographic features and enables easy editing and manipulation of the data.

What is the term used to describe the process of assigning geographic coordinates to features in a digital map?

  1. Digitizing

  2. Vectorization

  3. Rasterization

  4. Geocoding


Correct Option: D
Explanation:

Geocoding is the process of assigning geographic coordinates to features in a digital map. This allows the features to be located on the Earth's surface and enables spatial analysis and visualization.

Which type of digital map data structure stores features as a grid of cells, where each cell contains a single value?

  1. Raster

  2. Vector

  3. Topological

  4. TIN


Correct Option: A
Explanation:

Raster data structures store features as a grid of cells, where each cell contains a single value. This format is commonly used for representing continuous data, such as elevation or temperature.

What is the term used to describe the process of creating a three-dimensional representation of a landscape using digital elevation data?

  1. Digitizing

  2. Vectorization

  3. Rasterization

  4. TIN generation


Correct Option: D
Explanation:

TIN generation is the process of creating a three-dimensional representation of a landscape using digital elevation data. TIN stands for Triangulated Irregular Network, which is a data structure that represents the terrain as a series of interconnected triangles.

Which type of digital map data structure is commonly used for representing linear features, such as roads or rivers?

  1. Raster

  2. Vector

  3. Topological

  4. TIN


Correct Option: B
Explanation:

Vector data structures are commonly used for representing linear features, such as roads or rivers. This format allows for precise representation of the features and enables easy editing and manipulation of the data.

What is the term used to describe the process of converting digital map data into a printed map?

  1. Digitizing

  2. Vectorization

  3. Rasterization

  4. Cartographic output


Correct Option: D
Explanation:

Cartographic output is the process of converting digital map data into a printed map. This involves selecting the appropriate map projection, scale, and symbology, and then generating a high-quality print.

Which type of digital map data structure is commonly used for representing point features, such as cities or landmarks?

  1. Raster

  2. Vector

  3. Topological

  4. TIN


Correct Option: B
Explanation:

Vector data structures are commonly used for representing point features, such as cities or landmarks. This format allows for precise representation of the features and enables easy editing and manipulation of the data.

What is the term used to describe the process of overlaying multiple layers of digital map data to create a composite map?

  1. Digitizing

  2. Vectorization

  3. Rasterization

  4. Map overlay


Correct Option: D
Explanation:

Map overlay is the process of overlaying multiple layers of digital map data to create a composite map. This allows for the visualization and analysis of multiple datasets simultaneously.

Which type of digital map data structure is commonly used for representing topological relationships between features, such as adjacency and connectivity?

  1. Raster

  2. Vector

  3. Topological

  4. TIN


Correct Option: C
Explanation:

Topological data structures are commonly used for representing topological relationships between features, such as adjacency and connectivity. This format enables efficient spatial analysis and visualization.

What is the term used to describe the process of creating a digital map from scratch using source data, such as aerial imagery or topographic maps?

  1. Digitizing

  2. Vectorization

  3. Rasterization

  4. Map compilation


Correct Option: D
Explanation:

Map compilation is the process of creating a digital map from scratch using source data, such as aerial imagery or topographic maps. This involves selecting the appropriate data sources, georeferencing the data, and then digitizing or vectorizing the features.

Which type of digital map data structure is commonly used for representing three-dimensional features, such as buildings or mountains?

  1. Raster

  2. Vector

  3. Topological

  4. TIN


Correct Option: D
Explanation:

TIN (Triangulated Irregular Network) data structures are commonly used for representing three-dimensional features, such as buildings or mountains. This format allows for efficient storage and visualization of complex terrain.

What is the term used to describe the process of converting digital map data into a web-based format that can be accessed and viewed online?

  1. Digitizing

  2. Vectorization

  3. Rasterization

  4. Web mapping


Correct Option: D
Explanation:

Web mapping is the process of converting digital map data into a web-based format that can be accessed and viewed online. This involves creating interactive maps that can be explored and analyzed using a web browser.
