Abstract
The article reviews complex field studies, which are fundamental research methods in the physical-geographical direction of "Sciences of the Earth and the Environment". Component-by-component field study and description of natural-territorial complexes using the “Key Areas” method along the route, compiling a landscape profile, spatio-temporal analytics on digital platforms Ventusky and EOS, creating a database - are presented based on the results of a comprehensive long study by the authors of the geosystems of the Sharyn River basin located in Almaty areas. Methodological principles and approaches are analyzed in the field period of research and in the period of cameral processing. These questions are a practical confirmation of general theoretical knowledge about the structural organization, development, functional dynamics and variability of natural-territorial complexes. Physical and geographical studies acquire great scientific and practical relevance in the context of the influence of global changes in the natural environment at the regional level. The modern applied value of field studies of natural-territorial complexes, including hard-to-reach geosystems, is analyzed, the effectiveness of which is to study the structure, dynamics and variability in time and space, using the possibilities of digital technologies, ensuring the reliability of the results.
