A geological survey is a systematic study of the geology of a specific area, typically conducted by geologists and other earth scientists. The main goal of a geological survey is to gather information about the geological features, structures, and materials present in a particular region, as well as to assess potential geological hazards and resources. This can include mapping rock formations, studying fossils, analyzing soil composition, and identifying mineral deposits. Geological surveys are important for various applications, such as land development, natural resource exploration, environmental management, and hazard mitigation.
