Applications of Remote Sensing in Geomorphologic Mapping: A Case Study from the Karur District, Tamil Nadu, India
J. Muralitharan | K. Palanivel [2]
Abstract: The study of landforms, or geomorphology, provides an understanding of surface and subsurface processes that carved landforms on the Earth's surface over time. Geomorphology and ancillary information on geology, soil, vegetation, and hydrology help plan development in numerous fields. Geomorphological mapping and its applications have been carried out using satellite-based geospatial technology for the last five decades. Using satellite remote sensing's synoptic and temporal capability, different landforms can be depicted. The use of remote sensing enables rapid and systematic geomorphological mapping at a low cost and allows the detection and mapping of landforms in dynamic landscapes at various scales. Geomorphological mapping is discussed in this paper, along with remote sensing mapping techniques. IRS-P6 LISS-III (23.5 m) satellite images were used as the primary data source for the mapping. Additionally, ancillary data such as geological maps, topographic maps, digital elevation models (DEMs), field data collected by GPS systems, and web portals for image visualization were employed in the mapping process. Structural hill, linear ridge, inselberg, piedmont zone, colluvial fill, rocky pediment, buried pediment, older flood plain, and younger flood plain are the major geomorphological units found in the present study area. This study's output will help the geologist, water resources managers, and administrators to plan and administrate resources sustainably.
