Cartography and Geospatial Analysis Questions
Which GIS operation allows you to create a new layer representing the area that is common to two or more input layers?
-
Intersect
-
Union
-
Buffering
-
Dissolve
A
Correct answer
Explanation
The intersect operation in GIS allows you to create a new layer representing the area that is common to two or more input layers. It is commonly used to identify areas of overlap between different datasets.
Which GIS operation allows you to create a new layer representing the area that is outside of a specified area or boundary?
-
Buffering
-
Dissolve
-
Intersect
-
Difference
D
Correct answer
Explanation
The difference operation in GIS allows you to create a new layer representing the area that is outside of a specified area or boundary. It is commonly used to identify areas that are not covered by a particular dataset or to create exclusion zones.
Which of the following is NOT a common application of GIS in environmental monitoring?
-
Land use planning
-
Natural resource management
-
Pollution monitoring
-
Climate change modeling
D
Correct answer
Explanation
Climate change modeling is not typically considered a common application of GIS in environmental monitoring, as it involves complex climate models and simulations that are typically conducted using specialized software.
Which of the following is NOT a common type of GIS data?
-
Vector data
-
Raster data
-
Attribute data
-
Metadata
D
Correct answer
Explanation
Metadata is not a type of GIS data, but rather information about the data, such as its source, accuracy, and coordinate system.
Which of the following is NOT a common type of GIS analysis?
-
Buffer analysis
-
Overlay analysis
-
Network analysis
-
Time series analysis
D
Correct answer
Explanation
Time series analysis is not typically considered a common type of GIS analysis, as it involves analyzing data over time, which is typically done using specialized statistical software.
What is the term used to describe the process of creating a map using GIS software?
-
Mapping
-
Cartography
-
Visualization
-
Geospatial analysis
A
Correct answer
Explanation
Mapping is the process of creating a map using GIS software. This can involve adding layers of data, such as roads, rivers, and land use, and symbolizing the data in a way that is easy to understand.
Which of the following is not a type of geospatial data disseminated by NRSC?
-
Satellite imagery
-
Aerial photography
-
Topographic maps
-
Census data
D
Correct answer
Explanation
Census data is not a type of geospatial data disseminated by NRSC. Census data is collected by the Census of India and provides information on population, households, and other socio-economic characteristics.
What is the purpose of a treemap?
-
To display the distribution of data
-
To compare multiple datasets
-
To show the relationship between two variables
-
To identify clusters and patterns in data
D
Correct answer
Explanation
A treemap is a graphical representation of data where the individual values are represented by nested rectangles. Treemaps are useful for identifying clusters and patterns in data.
Which map projection is commonly used for navigation and is known for its ability to preserve angles and shapes?
-
Mercator Projection
-
Robinson Projection
-
Azimuthal Equidistant Projection
-
Lambert Conformal Conic Projection
A
Correct answer
Explanation
The Mercator Projection is a cylindrical projection that preserves angles and shapes, making it suitable for navigation and nautical charts.
What type of map is designed to show the distribution of a particular phenomenon across a geographic area?
-

Topographic Map
-
Road Map
-
Political Map
A
Correct answer
Explanation
A choropleth map uses colors or shades to represent the values of a quantitative variable across different geographic units.
Which of the following is a common method for representing data on a map using symbols?
-
Bar Chart
-
Pie Chart
-
Scatter Plot
-
Proportional Symbol Map
D
Correct answer
Explanation
A proportional symbol map uses symbols of varying sizes to represent the values of a quantitative variable at different locations.
What is the term for the process of transforming geographic data into a visual representation?
-
Geocoding
-
Georeferencing
-
Cartography
-
Digitizing
C
Correct answer
Explanation
Cartography is the art and science of creating maps and other visual representations of geographic data.
