3D visualization involves the use of geospatial data to create a realistic and interactive 3D representation of the Earth's surface, allowing users to explore and analyze the data in a more immersive way.

Multiple choice

Which of the following is NOT a common type of geospatial data used in Indian Geography applications?

  1. Satellite imagery

  2. LiDAR data

  3. Census data

  4. Hydrographic data
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

While census data is important for demographic studies, it is not typically considered geospatial data as it does not have a specific location associated with each data point.

Multiple choice

What is GIS?

  1. A system for capturing, storing, analyzing, and displaying geographic data

  2. A type of computer software used for creating maps

  3. A method for collecting and organizing data about the Earth's surface

  4. A tool for teaching geography in schools

Multiple choice

Which of the following is not a common type of land use planning tool?

  1. Zoning

  2. Comprehensive plan

  3. Subdivision regulations

  4. Building codes
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Building codes are not typically considered a land use planning tool, as they primarily focus on regulating the construction and safety of buildings rather than the overall use and development of land.
