Applied Geomatics, 2010
This paper presents the volume "Basics of Geomatics" (Springer, ISBN 978-1-4020-9013-4). The volume introduces in a systematic way the complex topics and techniques that can be assembled under Geospatial Information, namely, geodesy, cartography, photogrammetry, remote sensing, informatics, acquisition systems, global positioning systems, digital image processing, geographic information systems, decision support systems, and Web-GIS. It describes in detail and at an accessible level the state of current knowledge. As such, it will serve as a working tool not only to geoscientists and geographers but also to engineers, architects, computer scientists, urban planners, specialists in geographical information system, remote sensing, forestry, agricultural science, soil science geometry, environmental scientists, and managers. Applications can be found in security, risk management, monitoring, infomobility, geopositioning, food traceability, etc. tispectral and hyperspectral remote sensing from airplane and satellite, with images both passive optical and active microwave (radar) at different geometric, spectral, radiometric, and temporal resolutions, although there is still only limited awareness of how to use all the available potential correctly. The resulting data and information are represented in digital and numerical layers managed in Geographical Information Systems and Decision Support Systems, often based on the development of Expert Systems. Such a large amount of data must necessarily be organized, processed, handled, and used without delay for a correct representation of the territorial situation. These elements must be processed in an interdisciplinary and interoperable manner, and the discipline of geomatics (geos: Earth, matics: informatics) can satisfy such requirements. The term geomatics was created at Laval University in Canada in the early 1980s, based on the concept that the increasing potential of electronic computing was revolutionizing surveys and representation sciences and that the use of computerized design (video diagram) was compatible with the treatment of huge amounts of data. That period's revolutionary intuition was based on the geographical location of each object on our planet. Geomatics is defined as a systemic, multidisciplinary, integrated approach to selecting the instruments and the appropriate techniques for collecting, storing, integrating, modeling, analyzing, retrieving at will, transforming, displaying, and distributing spatially georeferenced data from different sources with well-defined accuracy characteristics and continuity in a digital format. Erected on the scientific framework of geodesy, it uses terrestrial, marine, airborne, and satellite-based sensors to acquire spatial and other data.

Every applied science is involved in some sort of data analysis, where the exarnination and further processing of the outcomes of observations leads to answers about some characteristics of the physical reality.
Geophysics: Principles, Applications and Emerging Technologies
2016
The rapid development of industrial and urban areas in the last decades caused a significant amount of environmental degradation with serious consequences to human life, ecosystems, natural resources, land utilization, as well as to human and natural heritage. Thus, the role of site restoration and rehabilitation projects, in the context of the Management Environmental degradation, is crucial for the modern society. Environmental Geophysics comprises a relative modern part of the Geophysics discipline, aimed at determining the physical properties of the shallow sub-surface by using non invasive high-resolution geophysical techniques. The detailed knowledge of the subsurface structure is valuable for a variety of disciplines involved in the study of the shallow earth's crust, which is directly related with human activities. In particular, Environmental Geophysics efficiently deals with technical problems arising during construction works such as karst collapse, evaporite sinkholes, landslides, mine subsidence and fault zones. Furthermore, it is involved in investigations concerning the detection of buried or abandoned waste, the location of the aquifer and part of its related properties to identify the possible presence of contaminants in the subsurface and finally, the mapping of archaeological sites. The aim of this work is to present the most familiar and robust techniques used in environmental geophysics and new methodologies of data processing and interpretation. Extensive literature research and examples from case studies are presented and analyzed. Special emphasis is given to the limitations of all applied techniques.
A Comparative Overview of Geophysical Methods
The shallow subsurface structure of the Earth is important to understand for many economic and safety reasons. The problem is usually difficult due to complexity of the earth's subsurface processes especially near the surface. A number of geophysical methods are used for this purpose using different physical characteristics of the Earth materials. A particular geophysical method illuminates part of the problem, but a reliable solution can only be found by combining results of different methods. In order to synthesize information from different geophysical methods, it is important to understand their similarities and differences. The aim of this study is to correlate the basic principles of geophysical methods side-by-side starting from fundamental equations. This study reveals that many analogies exist among these methods both in their mathematical formulation, and sometimes, in ways they are used in the geophysical applications.
Geodetic Monitoring as Support of Geodynamic Investigations–Indegen Project
Based on the previous geological and geophysical information a special network for geodynamic monitoring of the Romanian territory has been designed and achieved. The network consists of three lines crossing the major lithosphere contacts: the Tornquist-Teisseyre Zone (TTZ) separating the East European Plate from the Intra-Alpine Microplate (IaP), Peceneaga-Camena Fault, as the boundary between EEP and Moesian Microplate (MoP), and the Trans-Getica Fault (TGF) between MoP and IaP. The fourth line is crossing the Vrancea active geodynamic area located in the bending area of East Carpathians. The project INDEGEN (grant CEEX-2 MENER no. 732/2006-2008) started in 2006 with a duration of three years, managed by the Institute of Geodynamics of the Romanian Academy in co-operation with other scientific organizations: Technical University for Civil Engineering – Faculty of Geodesy, University of Bucharest, Geological Institute of Romania, and National Institute for Earth Physics.
