What Is a Topographic Survey?

Geomorphology survey is the basic method to study geomorphology. Its task is to first determine the landform morphological characteristics, combined with a series of conditions such as material composition and structure, to determine the cause and formation process of the landform, and to provide a basis for finding groundwater, mineral resources and engineering construction. When geomorphological surveys and geological surveys are combined, survey routes can overlap. When special geomorphological surveys are conducted, a comprehensive study of the topographic maps, aerial photos, satellite photos and other data of the survey area should be conducted first, so as to have a general concept of the geology and geomorphology of the entire area, and provide a basis for determining specific survey plans and routes. ^[1]

Geomorphological surveys include geomorphological descriptions, morphological measurements, genesis, material composition, modern processes, sections, sketches, and photographs. Before carrying out a geomorphological survey, a comprehensive study of the topographic maps, aerial photos, satellite photos and other data of the survey area should be carried out in order to have a general concept of the geology and geomorphology of the entire area and provide a basis for determining the survey plan and route.
