Explanation:

Mosaicking is the process of combining multiple remotely sensed images of the same area taken at different times to create a single, seamless image.

Which GIS operation is commonly used to analyze the spatial relationships between different geospatial features?

  1. Buffering

  2. Overlay Analysis

  3. Image Classification

  4. Georeferencing


Correct Option: B
Explanation:

Overlay Analysis is a GIS operation that allows users to combine multiple geospatial layers to identify areas where they overlap or intersect.

What is the term used to describe the process of converting remotely sensed data into a format that can be used by GIS software?

  1. Georeferencing

  2. Mosaicking

  3. Warping

  4. Preprocessing


Correct Option: D
Explanation:

Preprocessing is the process of converting remotely sensed data into a format that can be used by GIS software, which may involve radiometric and geometric corrections.

Which of the following is NOT a common method for integrating GIS and Remote Sensing data for disaster management?

  1. Damage Assessment

  2. Evacuation Planning
