Which of the following is NOT a type of remotely sensed data commonly used for land use/land cover mapping?

  1. Optical imagery

  2. Radar imagery

  3. Thermal imagery

  4. LiDAR data


Correct Option: D
Explanation:

LiDAR data is not typically used for land use/land cover mapping, as it provides information on the elevation and structure of the Earth's surface, rather than the land cover.

What is the primary advantage of using remote sensing data for land use/land cover mapping?

  1. It provides a synoptic view of a large area.

  2. It can be used to identify land cover types that are difficult to distinguish on the ground.

  3. It can be used to monitor changes in land cover over time.

  4. All of the above.


Correct Option: D
Explanation:

Remote sensing data offers several advantages for land use/land cover mapping, including the ability to provide a synoptic view of a large area, identify land cover types that are difficult to distinguish on the ground, and monitor changes in land cover over time.

Which of the following is NOT a common GIS operation used in land use/land cover mapping?

  1. Image classification

  2. Change detection

  3. Buffer analysis

  4. Network analysis


Correct Option: D
Explanation:

Network analysis is not typically used in land use/land cover mapping, as it is primarily used for analyzing the connectivity and flow of objects in a network, such as roads or rivers.

What is the most common method used for image classification in land use/land cover mapping?

  1. Supervised classification

  2. Unsupervised classification

  3. Object-based classification

  4. Random forest classification


Correct Option: A
Explanation:

Supervised classification is the most commonly used method for image classification in land use/land cover mapping, as it involves training the classifier using a set of labeled samples.

Which of the following is NOT a common application of land use/land cover maps?

  1. Land use planning

  2. Environmental impact assessment

  3. Natural resource management

  4. Climate change modeling


Correct Option: D
Explanation:

Climate change modeling is not a common application of land use/land cover maps, as it typically requires data on other factors such as climate variables and greenhouse gas emissions.

What is the primary challenge in using remote sensing data for land use/land cover mapping in India?

  1. Lack of high-resolution satellite imagery

  2. Cloud cover

  3. Complex land use patterns

  4. All of the above


Correct Option: D
Explanation:

All of the above factors pose challenges in using remote sensing data for land use/land cover mapping in India.

Which of the following is NOT a benefit of using GIS for land use/land cover mapping?

  1. It allows for the integration of multiple data sources.

  2. It enables the analysis of spatial relationships between land cover types.

  3. It can be used to create visually appealing maps.

  4. It can be used to predict future land use changes.


Correct Option: D
Explanation:

GIS cannot be used to predict future land use changes, as it is a tool for analyzing and visualizing spatial data, not for making predictions.

What is the primary advantage of using object-based classification for land use/land cover mapping?

  1. It can handle high-resolution imagery.

  2. It can incorporate contextual information.

  3. It is less sensitive to noise and outliers.

  4. All of the above.


Correct Option: D
Explanation:

Object-based classification offers several advantages for land use/land cover mapping, including the ability to handle high-resolution imagery, incorporate contextual information, and reduce sensitivity to noise and outliers.

Which of the following is NOT a common method for change detection in land use/land cover mapping?

  1. Image differencing

  2. Post-classification comparison

  3. Vegetation indices differencing

  4. Principal component analysis


Correct Option: D
Explanation:

Principal component analysis is not typically used for change detection in land use/land cover mapping, as it is primarily used for reducing the dimensionality of a dataset.

What is the primary challenge in using GIS for land use/land cover mapping in urban areas?

  1. High density of buildings and infrastructure.

  2. Complex land use patterns.

  3. Lack of accurate and up-to-date data.

  4. All of the above.


Correct Option: D
Explanation:

All of the above factors pose challenges in using GIS for land use/land cover mapping in urban areas.

Which of the following is NOT a common data source used for land use/land cover mapping in India?

  1. Satellite imagery

  2. Census data

  3. Topographic maps

  4. Soil maps


Correct Option: D
Explanation:

Soil maps are not typically used for land use/land cover mapping, as they provide information on the physical and chemical properties of the soil, rather than the land cover.

What is the primary advantage of using random forest classification for land use/land cover mapping?

  1. It can handle large datasets.

  2. It is robust to noise and outliers.

  3. It can be used to estimate the uncertainty of classification results.

  4. All of the above.


Correct Option: D
Explanation:

Random forest classification offers several advantages for land use/land cover mapping, including the ability to handle large datasets, robustness to noise and outliers, and the ability to estimate the uncertainty of classification results.

Which of the following is NOT a common application of land use/land cover maps in India?

  1. Agricultural land use planning

  2. Forest management

  3. Water resources management

  4. Disaster management


Correct Option: D
Explanation:

Land use/land cover maps are not typically used for disaster management in India, as they do not provide information on the vulnerability of different land cover types to natural hazards.

What is the primary challenge in using GIS for land use/land cover mapping in rural areas?

  1. Lack of accurate and up-to-date data.

  2. Complex land use patterns.

  3. High density of buildings and infrastructure.

  4. All of the above.


Correct Option: A
Explanation:

The primary challenge in using GIS for land use/land cover mapping in rural areas is the lack of accurate and up-to-date data.

Which of the following is NOT a common method for accuracy assessment in land use/land cover mapping?

  1. Error matrix

  2. Kappa coefficient

  3. F1 score

  4. Receiver operating characteristic curve


Correct Option: D
Explanation:

Receiver operating characteristic curve is not typically used for accuracy assessment in land use/land cover mapping, as it is primarily used for evaluating the performance of binary classifiers.
