Integrating Remote Sensing (RS) and Geographic Information Systems (GIS) provides a powerful workflow for analyzing Land Use/Land Cover (LULC) changes over space and time. RS supplies the essential multi-temporal imagery (e.g., from satellites), which is then classified to create LULC maps for different dates. GIS acts as the analytical platform, integrating these maps with other spatial data (like elevation or boundaries), performing change detection analysis (like post-classification comparison) to identify where and what types of changes occurred, quantifying these changes, and visualizing the results. This integration enhances accuracy by allowing the use of contextual spatial data from GIS to refine RS classifications.

However, significant challenges exist:

Addressing these requires careful methods, advanced algorithms (increasingly AI), and robust validation, but the RS-GIS combination remains the standard approach for LULC change studies.

Remote sensing and Geographic Information System (GIS) techniques can be effectively integrated to accurately analyze spatial and temporal changes in land use and land cover (LULC) by utilizing multi-temporal satellite imagery and spatial analysis tools to detect, map, and quantify changes over time. Remote sensing provides consistent and repetitive coverage of the Earth's surface, enabling the extraction of LULC information through classification algorithms and image interpretation. GIS complements this by offering robust spatial data management, visualization, and analytical capabilities, allowing for the integration of various datasets, detection of patterns, and assessment of change dynamics. Together, these technologies facilitate comprehensive monitoring, modeling, and decision-making processes for sustainable land management and environmental planning.

As far as I am concerned, from the aspects of Geographers, Integrating Remote Sensing and geographic Information systems techniques provide a powerful approach for analyzing spatial and temporal changes in land use and land cover. For more information here are details: We should consider (1)Data Acquisition (RS) it refers to both Satellite/ Aerial Imagery and Preprocessing. Let`s see each in details as follows: Satellite/ Aerial Imagery refers to use multi-temporal images like Landsat-sentinel-2, MODIS, or high-resolution data like Quick Bird, SPOT). Plus, ensure consistent spatial, spectral and temporal resolution. whereas, Preprocessing: radiometric correction, for instance, atmospheric correction using FLAASH, DOS. Geometric correction, Co-registration of multi-temporal images. Plus, Image Enhancement, such as, NDVI for vegetation analysis.

(2) Land Use/ Land cover Classification: it refers to Supervised Classification, for instance, Maximum Likelihood, random Forest, SVM. Unsupervised Classification, for instance, ISODATA, K-means. Object-Based Image Analysis, for instance, for high-resolution imagery. machine Learning or Deep Learning, for example, CNN for automated feature extraction. (You can see for more details here: LULC maps for different time periods, for instance, 2000, 2010, and 2020). (3) Change Detection Analysis:

this refers to Post-Classification Comparison, such as compare classified maps from different years to identify transitions like forest-urban. etc.

Generally, Researchers should Integrating Remote Sensing and GIS by tracking LULC changes, identify driving factors and support sustainable and management decision in advance.
