Geoinformatics plays a critical role in understanding, analyzing, and managing landslides by integrating spatial data, remote sensing, and geographic information system (GIS) technologies. Landslides are complex natural phenomena influenced by geological, hydrological, and anthropogenic factors, and geoinformatics provides a comprehensive framework to study these factors systematically. Remote sensing is one of the primary tools in landslide studies. Satellite imagery and aerial photographs allow for large-scale monitoring of susceptible areas. Multispectral and hyperspectral images help identify lithological units, soil types, vegetation cover, and moisture content, all of which are crucial for assessing slope stability. High-resolution satellite data, such as from Sentinel or Landsat series, provide temporal information that enables detection of pre- and post-landslide changes.
