Abstract
Seismic activity in Izvoarele - Galaţi area, identified as a “seismic swarm” has started at 23rd of September 2013 with pulses activity. More than 250 earthquakes have been produced in a month with 19 events of ML>3 and 40 with ML>2 situated close to the Negrea village. The earthquake area it is oriented NE-SW perpendicular on the main tectonic faults Peceneaga Camena (South) and Sfântu Gheorghe (North). But the events are felt with maximum amplitude on the Izvoarele village due to local conditions.
Since 4th of October 2013, Technical University of Civil Engineering by Research Centre on Space Geodesy, Photogrammetry, Remote Sensing and GIS (GEOS) has started GNSS studies on Izvoarele – Galaţi area. There are performed three observations phases in order to detect crustal movements by a GNSS network situated on that area. The paper presents results obtained after first two observations phases with site displacements of few centimeters.
Keywords: seismic swarm, earthquakes, GNSS observations, crustal movements

Abstract
Systematic cadastre is a complex work that combines technical engineering skills, legal knowledge and skills in information technology, specific to working with databases.
In the present article we have presented the practical aspects and characteristics of a systematic cadastral work, highlighting the current technical solutions.
The practical result of this work, expressed in the case study is materialized by presenting problems encountered in this type of work and addressed solutions.

The favourable influence valuation of land covered by water
Daniela Lăcătușu (married Răboj), Dumitru Onose
Received: April 2015 / Accepted: September 2015 / Published: Iune 2016
Abstract
This article emphasizes the steps required for the application an valuation methodology for land covered by water. This process is addressed to the public institution in Romania, that manages this type of land (swamp areas, artificial lakes or floodable areas). In the article are followed the rules and the legislation of Romania, and the principles presented may have large scale applicability.
Keywords: lands covered by water, CMBU (the highest and the best use), market value, valuation report

Measuring the distances wyth topographic equipment in the geodesic base of the National Institute of Metrology from Bucharest
Valentin Mihalcea, Dumitru Onose
Received: April 2015 / Accepted: September 2015 / Published: Iune 2016
Abstract
This article presents some theoretical and practical aspects of topographic devices calibration topographic. It highlights how important it is to pay attention before you start working with these devices, namely to consider introducing the atmospheric parameters for setting the EDM instrument. It is very important to monitor and take into account the environmental conditions before starting the measurements?

Qualitative Indicators Used For the Optimization of 3D Geodetic Networks

Received: April 2015 / Accepted: September 2015 / Published: Iune 2016
Abstract
Geodetic network optimization (or geodetic network design) is a notion first introduced by Erik Grafarend (b. 1939). The scope of the optimization is to improve the geodetic network configuration and the measurements plan, in order to achieve the desired accuracy for the final results, in a cost-effective way. In this paper are presented some of the qualitative indicators used for the optimization of the tridimensional geodetic networks, together with a case study which reveals the applicability of these quantities to the presented situation.
Keywords: geodetic network, optimization, measurement, redundancy, reliability

Identifying linearity/non-linearity in landscape evolution by integrating satellite-based radar interferometry and ground-based monitoring data. Study area: Bucharest
Iuliana Armas, Mihaela Gheorghe, Alexandru Calin, Paul Daniel Dumitru, Octavian Mihai Badescu
Received: April 2015 / Accepted: September 2015 / Published: Iune 2016
Abstract
This research project aims to identify landscape evolution trends in Bucharest based on high-resolution interferometric ground displacement products, using single and dual-polarimetric satellite data. The results based on multitemporal InSAR methodologies (initially applied to ERS, ENVISAT satellite data and later refined using TerraSAR-X/TanDEM-X satellite data), validated by ground-based monitoring data and conventional geological and geomorphological methods will capture the space-time evolution of the city. The understanding of these phenomena have long term theoretical and practical results in the context of climate change, offering the support to successful risk mitigation actions in urban areas. The outcome of the project will include validated interferometric-based ground displacement products in urban areas and a more effective process of interpretation of complex dynamics based on a holistic approach achieved by a multidisciplinary team of scientists and engineers.

A comparative survey on the polarimetric SAR data target decomposition techniques
Radu Tănase, Dan Răducanu, Mihai Datcu
Received: April 2015 / Accepted: September 2015 / Published: Iune 2016
Abstract
The polarimetric synthetic aperture radar (PolSAR) system emits microwaves on two orthogonal polarizations (the most often horizontal and vertical) and receives the backscattered echoes on the same two polarizations to synthesize recordings of the ground scene. The information embeded in the four resulted polarimetric channels fully describes the backscattering properties of the recorded ground objects. In order to take full advantage of this information and to extract the physical properties of the recorded targets, simple falsecolor representations of the polarimetric channels are not sufficient, so several coherent and incoherent target decomposition theorems have been proposed in the state-of-the-art literature. All these decompositions assume the fact that any scattering mechanism can be represented as the sum of some simpler, ,,canonicalˮ scattering mechanisms. The aim of this paper is to perform a comparative survey on these decomposition techniques and to provide examples using two PolSAR datasets: a Lband PALSAR image over Danube's Delta, Romania, and a C-band RadarSAT2 image over Brăila, Romania.
Keywords: polarimetric synthetic aperture radar, scattering mechanisms, coherent target decomposition, incoherent target decomposition, PALSAR, RadarSAT2.
