The Correct answer is: Only 3

Key Points

• Large-scale maps depict more detailed information about a large area, such as topographical maps:
  • This statement is incorrect.
  • Large-scale maps do not cover a large area; instead, they represent a small area with greater detail.
  • Topographical maps are detailed, but they are examples of large-scale maps covering smaller regions.
  • The term "large-scale" refers to the largeness of the ratio (e.g., 1:25,000), not the geographical extent.
• Small-scale maps depict smaller areas with great detail:
  • This statement is incorrect.
  • Small-scale maps represent larger geographical areas with less detail due to smaller representative fractions (e.g., 1:1,000,000).
  • They are used for world maps, continent maps, or country-wide maps where only general features are shown.
• A large-scale map might have a scale like 1 cm = ½ km:
  • This statement is correct.
  • This scale (1:50,000) is considered a large scale because the map shows a small area in greater detail.
  • Such scales are typical in topographical and cadastral mapping where high accuracy is important.

Additional Information

• Large-Scale Maps:
  • Cover small areas with high detail (e.g., 1:25,000, 1:50,000).
  • Useful for construction, land records, and administrative planning.
• Small-Scale Maps:
  • Cover large areas with less detail (e.g., 1:1,000,000 or more).
  • Common in atlases and wall maps to give a broad overview of continents or countries.
• Mnemonic Tip:
  • Large-scale = large detail = small area
  • Small-scale = small detail = large area

Key Points

• What-if analysis allows users to change input variables to see different possible outcomes.
• It helps in understanding the implications of varying key parameters in the decision-making process.
• This type of analysis is crucial in risk management where various scenarios need to be evaluated.
• Using GIS-based tools, what-if analysis can be conducted in a spatial context to visualize impacts on different regions.

Additional Information

• GIS (Geographic Information System):
  • A system designed to capture, store, manipulate, analyze, manage, and present spatial or geographic data.
  • It helps in visualizing data in a way that reveals relationships, patterns, and trends in the form of maps, globes, reports, and charts.
  • GIS technology is used in various fields including urban planning, environmental science, transportation, and public health.
• Risk Decision-Making Process:
  • A systematic approach to identifying, assessing, and managing risks.
  • It involves the process of determining the likelihood and consequence of events and taking appropriate actions to mitigate or capitalize on these risks.
• Sensitivity Analysis:
  • A technique used to determine how different values of an independent variable affect a particular dependent variable under a given set of assumptions.
  • This helps in understanding the robustness of an outcome in response to changes in input variables.
• Scenario Analysis:
  • A process of analyzing possible future events by considering alternative possible outcomes (scenarios).
  • It is used to make strategic decisions by evaluating the effect of different decisions under various scenarios.

The correct answer is 'Choropleth Maps'

Key Points

• Choropleth Maps:
  • Choropleth maps are specifically designed to display statistical data, such as population density, across predefined regions or areas.
  • These maps use different shades or colors to represent varying levels of a particular attribute, such as population density, within each region.
  • The intensity of the color typically indicates the magnitude of the attribute, making it easy to compare different regions at a glance.
  • Choropleth maps are commonly used in demographics, economics, and other fields to visualize data distribution across geographical areas.

Additional Information

• Flow Maps:
  • Flow maps are used to visualize movement or flow of objects, such as migration, trade routes, or traffic, rather than static data like population density.
• Isarithmic Maps:
  • Isarithmic maps, also known as contour maps, use lines to connect points of equal value. They are often used to represent continuous data, such as temperature or elevation, rather than discrete population density values.
• Dasymetric Maps:
  • Dasymetric maps are used to improve the representation of statistical data by refining spatial units based on ancillary information, but they are less commonly used for population density compared to choropleth maps.

The correct answer is 100 m.

Key Points

• The contour interval is the vertical distance or difference in elevation between contour lines on a topographical map.
• It is used to depict the terrain's elevation and the slope of the land.
• In the Survey of India (SOI) topographical maps, the standard contour interval is 100 meters.
• This interval is chosen to provide a clear and understandable representation of the terrain over larger areas and variations in elevation.
• Smaller contour intervals, such as 10 meters or 20 meters, are used in maps where more detailed elevation data is required.

Additional Information

• The choice of contour interval depends on the scale of the map and the nature of the terrain.Maps with a larger scale (showing a smaller area) may use smaller contour intervals for greater detail.
• Conversely, maps with a smaller scale (showing a larger area) may use larger contour intervals for simplicity and clarity.
• Understanding contour intervals is crucial for activities such as hiking, land surveying, and urban planning.
• The SOI topographical maps are widely used in India for various applications, including geological studies, environmental management, and infrastructure development.
