a) Water quality monitoring
b) Flood prediction
c) Watershed delineation
d) Irrigation scheduling
Answer: c) Watershed delineation
Explanation: GIS is used to delineate watersheds, which are essential for managing water resources effectively. It helps in understanding the flow of water and identifying areas vulnerable to pollution or erosion.
3. Urban planners use GIS primarily for:
a) Identifying suitable locations for new infrastructure
b) Traffic management
c) Environmental impact assessment
d) Urban beautification projects
Answer: a) Identifying suitable locations for new infrastructure
Explanation: GIS allows urban planners to analyze spatial data to identify suitable locations for new infrastructure projects, such as roads, schools, and parks, based on factors like population density, transportation routes, and environmental considerations.
4. In environmental planning, GIS is useful for:
a) Wildlife conservation
b) Air quality monitoring
c) Waste management
d) All of the above
Answer: d) All of the above
Explanation: GIS is a versatile tool in environmental planning, used for various purposes including wildlife conservation, air quality monitoring, and waste management. It helps planners make informed decisions by analyzing spatial data related to environmental factors.
5. Which application of remote sensing is crucial for natural resource management?
a) Crop monitoring
b) Forest mapping
c) Soil erosion detection
d) All of the above
Answer: d) All of the above
Explanation: Remote sensing is utilized in natural resource management for various purposes, including monitoring crops, mapping forests, and detecting soil erosion. It provides valuable data for assessing the health and sustainability of natural resources.
6. Location Based Services (LBS) primarily rely on which technology?
a) GPS
b) Radar
c) LiDAR
d) Sonar
Answer: a) GPS
Explanation: Location Based Services (LBS) rely on GPS (Global Positioning System) technology to determine the geographical location of a user’s device or vehicle. This enables the delivery of location-specific information or services.
7. Which of the following is NOT an application of Location Based Services (LBS)?
a) Navigation
b) Social networking
c) Weather forecasting
d) Emergency services
Answer: c) Weather forecasting
Explanation: While LBS can provide real-time weather updates based on the user’s location, weather forecasting itself is not a direct application of LBS. Navigation, social networking, and emergency services are common applications of LBS.
8. How does GIS contribute to traffic management?
a) By optimizing traffic signal timings
b) By analyzing traffic flow patterns
c) By identifying congestion hotspots
d) All of the above
Answer: d) All of the above
Explanation: GIS contributes to traffic management by optimizing traffic signal timings, analyzing traffic flow patterns, and identifying congestion hotspots. It helps authorities make data-driven decisions to improve traffic efficiency and safety.
9. Which aspect of land use analysis does remote sensing primarily focus on?
a) Land ownership
b) Vegetation cover
c) Population density
d) Infrastructure development
Answer: b) Vegetation cover
Explanation: Remote sensing is particularly useful for analyzing vegetation cover as it provides detailed imagery of land surfaces. This information is crucial for assessing land use patterns, ecosystem health, and biodiversity.
10. What makes Location Based Services (LBS) relevant in today’s society?
a) Increased smartphone usage
b) Advancements in GPS technology
c) Growing demand for personalized services
d) All of the above
Answer: d) All of the above
Explanation: Location Based Services (LBS) have become increasingly relevant due to increased smartphone usage, advancements in GPS technology, and the growing demand for personalized services tailored to users’ locations. These factors have driven the widespread adoption of LBS in various industries.
