Soil Environmental Studies with Application of Space Technology Advances and Geotechnical Investigations

Abstract

An investigation of soil contamination is a very important issue in soil environmental studies. It leads to classification of all living organisms in the soil, as well as essential materials and particles that these organisms use to survive which together form the soil ecosystem. It is vital to study the soil ecosystem to understand interface and relationship of organisms existing in the soil and their impact to environment surrounding them. Soil environmental study attracts an interest of scientists as one of the main factors of human live safety aspect. It is necessary to find out the way of combining of practical analysis and interpretation of soil surface information with further classification of environmental factors. Geotechnical investigations are useful instruments in soil quality studies. They are based on the field measurements, soil, and groundwater sampling directly from studied area. The samples are then analyzed in laboratories with appropriate equipment and chemical substances to determine their mineral composition, physical and mechanical properties, and extents of pollution. Remote Sensing method and Geographical Information Systems (GIS) represent the technology where geospatial data can be represented in the graphic form integrated into the geotechnical, geological and hydrological information routinely used by geotechnical engineers. Remote Sensing and GIS make available wide forms of spatial data to be integrated, selected, and sorted with any number of physical, chemical, or any possible environmental factors accessed by geotechnical measurements. There are number of existing traditional methods for soil environmental studies. It is extremely important to use advances of technology for daily human social and public needs maintaining and satisfactions.
