Geodesic tasks of global monitoring

Abstract

The rapidly developing anthropogenic impact on the environment generates a need for a monitoring system based on aerospace methods of Earth observation. The foundation of monitoring feasibility study is cartographic materials based on aerospace information as well as traditional geodetic methods. One of the main elements of any sectoral and global monitoring system is the definition of the list of objects, with allocation of qualitative and quantitative characteristics. In the context of global monitoring, this process is performed more appropriately on the basis of remote sensing materials. In this case structural analysis of aerospace monitoring information support becomes very important. Detailed elaboration of monitoring object interpretation features allows increasing information content of cartographic materials. When interpreting boundaries of monitoring objects, the most important are plan outlines and internal structure of the researched object. Effective investigation of environmental monitoring problems on a global scale is based on integrated use of aerospace, topographic and geodetic methodology. The author's concept of classification of cartographic support for global monitoring expands the research tools for the assessment of global processes of change in the Earth's surface. The use of predictive cartographic materials in the step-by-step monitoring of global exogenous processes is the most effective tool for fixing changes in landforms.
