Give an account of research framework and research design in the context of remote sensing and GIS based research.

A research framework and research design play a crucial role in structuring and guiding remote sensing and GIS-based research. These components ensure systematic data collection, analysis, and interpretation, facilitating meaningful scientific outcomes.  

### Research Framework in Remote Sensing and GIS-Based Research  

A research framework provides a conceptual structure for understanding the research process, defining objectives, and ensuring a logical sequence of activities. It integrates various components, including theoretical perspectives, methodologies, and data sources, tailored to geospatial studies.  

1. Problem Identification and Objectives  
   - The research begins with identifying a geospatial problem, such as land-use change, environmental monitoring, disaster risk assessment, or urban expansion.  
   - Clearly defined objectives guide the research direction and determine the selection of remote sensing and GIS techniques.  

2. Literature Review  
   - Examining previous studies helps in understanding existing methodologies, datasets, and technological advancements.
