Abstract :
The study of landforms is critical for understanding geomorphic processes and environmental changes. This
research integrates GPS data and high-resolution satellite imagery to analyze and monitor landform dynamics in some parts
of Southeastern Nigeria. Using advanced remote sensing techniques, precise Digital Elevation Models (DEMs) and
conducted detailed topographic analyses to identify and classify landforms were generated. The GPS data provided accurate
elevation and location information, which was essential for refining DEMs and enhancing the accuracy of landform
mapping. Change detection analysis was employed to track temporal shifts in landforms, revealing significant changes in
erosion patterns and landslide activities. Ground-Truthing efforts validated the accuracy of the remote sensing data,
demonstrating a strong correlation between field observations and the results obtained from GPS and satellite data
integration. The findings of this study offer new insights into the geomorphic processes shaping the study area and highlight
the effectiveness of combining GPS and satellite imagery for landform analysis. These results have important implications
for environmental management, hazard assessment, and future geomorphological research.
