This paper aims to present how 3D modeling technique based on digital images demonstrates usefulness of photogrammetry and accurate 3D visualization of real object that presents regular shapes (buildings, monuments, artifacts). The 3D model of a building facade has been obtained using Agisoft Photoscan software using two photos and the accuracy of this model is less than one pixel. We can also made a 3D analysing on the model. Totally automated workflow provides the ability to process images without advanced knowledge of modeling or processing thousands of aerial or terrestrial images. The importance of this aplication reflects the accesibility of this software that can process photos captured with a resonable camera using in fact a „low-cost” photogrametric technology, the photogrammetry becoming the best alternative of standard measuring techniques.

The paper aimed to present the organization of immovable property registering process encompassed in cadastral works made in Republic of Moldova. It is based on the 828-XII / 25.12.1991 law from Moldova's land code especially on the 12th and 13th articles. The four main registering categories are divided into primary, selective, massive and current recording of immovable property followed up by the principles and objectives of the registering process. An illustration of a primary massive registration of a field acquired under the law reveals a chain of certain particularities concerning content of immovable property, manner of acquiring the property and method of organization of registering process. Acquiring the property rights under the law has its own particularities as well. Further on, the 12th article provides that a committee is gathered in order to establish the various social categories of people that are entitled to receive land as owners whereas actual ascription of property is regulated by the 13th article, both of them assuring the legal foundation on which the right of property is formed. As a conclusion, the forming of immovable property implies the materialization of the right acquired under the 12th article of the land code. Moreover, the 12th article provides a rights authentication title for the land owner issued by central and local authorities.

In our case , a company wants to offer the employees a small trip somewhere in a mountain resort where they can improve their skills of working as a team and create a closer connection between them . The company has a few options but it’s hard to make a choice for a certain destination, so someone decides to make a StoryMap which can be shown to the employees and to the people responsible for deciding the destination in order for them to choose the best option. The same method can be used for choosing an adecvate location when a company wants to expand or someone wants to open a new store. GIS can be used for any study or observation related to the location of something , having a large field of application . In our paper we will analyze a few possible mountain destinations in terms of which one has the most ski slopes, which one offers the best possibilities for accommodation and which one has the best location from a geographical point of view. There will also be a short presentation of each mountain resort containing some pictures from the resort and possibly even some live images from the ski slopes , so the people in charge of making the decision will be very well informed about each possible destination. In parallel with this StoryMap we will also locate the respective places in a 3D scene, wich will increase the understanding of the geographical location for that area.

The following paper regards the creation of the digital plan necessary for the design and trace of a construction situated in the town of Colibita, in the Bistrita-Nasaud county. Further, the paper presents the methods of tracing and the study of accuracy in regards to the transposition on terrain of the projected objective. The methods used for drawing in a plan of the projected points of a construction results combining topographic mapping elements (angles and horizontal distances) and deploys according of well defined procedures. Before starting a construction, first you should realize the preparing of terrain by topographical point of view. This fact consists of an ensemble of operations made at office for making the construction at that terrain. For drawing of the projected elements, polar coordinates method has been chosen. This is the most used method of drawing, it is used for drawing on the terrain of project points in case if exists a drawing base or a drawing network, a poligonometric network, a topographic construction network.

As the European GNSS Agency (GSA) is emphasizing its efforts in implementing EGNOS based operations in various domains, such as maritime navigation or precision farming, and as the European Commission (EC) is considering extending the EGNOS coverage to Eastern Europe, it becomes demanding to start using EGNOS at national level. A first step in such direction is decoding the transmitted messages. This paper presents a MATLAB approach of decoding different EGNOS messages types and extracting the necessary information for computing the protection levels. In order to test the decoded messages, the European Space Agency’s SBAS Teacher tool will be used for comparison

The purpose of this paper is to present the methods of solving the basic geodetic problems. Taking advantage of numerical integration, we solve the direct and inverse geodetic problems on the ellipsoid. In general, the solutions are composed of a strict solution for the sphere plus a correction to the ellipsoid determined by numerical integration. The problems in geodesy are usually reduced to two main cases: the direct problem, given a starting point and an initial heading, find the position after traveling a certain distance along the geodesic; and the inverse problem, given two points on the ellipsoid find the connecting geodesic and hence the shortest distance between them. Much of the early work on these problems was carried out by mathematicians—for example, Legendre, Bessel, and Gauss—who were also heavily involved in the practical aspects of surveying. If the Earth is treated as a sphere, the geodesics are great circles (all of which are closed) and the problems reduce to ones inspherical trigonometry. For a sphere the solutions to these problems are simple exercises in spherical trigonometry, whose solution is given by formulas for solving a spherical triangle.

The first step to be run as part of the compensation is to determine preliminary coordinates. They are determined with a precision low accuracy generally depends on the purpose and length of the sides of the network considered. Because the projection system used officially in Romania is 1970 stereographic system for processing observations is usually a two-dimensional system still will consider that this plan is the reference surface which will reduce geodetic observations. If the geodesic network of the distance measurements were made, to be reduced from the reference surface selected. After being corrected physical (generally modern tools to measure distances apply this correction automatically) distances measured to be applied, in order, the following discounts: Reducing the chord; Reduction of the reference ellipsoid surface; Reduction plan stereographic projection in 1970.This stage of preliminary processing geodetic observations and reduction in the chosen reference surface is considered performed by the user, for which the program will be introduced reduced to the reference surface observations.

The object of our study is the spherical excess and the national geodetic network for the city of Cluj-Napoca. As a proof of the earth's rotundity, many place great reliance upon what is called the "spherical excess," which has been observed on making trigonometric observations on a large scale. The angles taken between any three points on the surface of the earth by the theodolite are, strictly speaking, spherical angles, and their sum must exceed 180 degrees; and the lines bounding them are not the chords as they should be, but the tangents to the earth. This excess is inappreciable in common cases, but in the larger triangles it becomes necessary to allow for it, and to diminish each of the angles of the observed triangle by one-third of the spherical excess. In other words, the spherical excess is represented by the difference between the sum of the angles of a spherical triangle and the sum of the angles of a plane triangle. The national geodetic network and the triangulation network represent the fixed points which form the base of all leveling procedures. Considering the distance between the points and the measurements accuracy, the points that form the geodetic network are classified in five categories: first order: the points are situated between 20-60 km, average 30 km, second order: the tips of the triangles are intercalated in the points of first order at distances between 10-20 km, average 15km,third order: the points are situated inside of the triangles of the second order at distances between 5-10 km, average 7 km, forth order: the points are situated inside of the triangles of the third order at the average distance of 3 km, fifth order: the points are situated inside of the triangles of the forth order at the average distance of 1.5 km. In our project we are using the points of the third order to determine the spherical excess in the city of Cluj-Napoca.

The main objective of the project is estimating deformations of Giurgiu-Russe bridge superstructure using analytical photogrammetry. The results of the observations help us to establish what is the deformations state of the bridge, and what kind of subsides can appear over the years. There are two methods for measurement of the subsides through photogrammetry: main time base and main real space base. Measurements were realized using a terrestrial photogrammetric camera UMK 10/1318 and digital processing was achieved using the relationships of the parallax differences in every superstructure pursuit mark.

Projection of topographic elements from the topographic surface on the reference surface is a very important operation necessary because the field observations are reported at the geoid vertical by the position of the plumb line, while the calculus are performed on ellipsoid after the instrumental observation were projected on the reference ellipsoid after the normal direction to the ellipsoid. For the correction calculus of reduction on ellipsoid of geodetic observation is necessary the preliminary determination of the ,,N” geoid undulation and the deviation components of vertical line. There are several methods in which we can bring geodetic points of the topographic surface to the reference surface. Some of the methods are: the design method, the development method, the Pizzetti method, the Bruns-Helmert method.

The paper aims to identify and analyse factors that affect the precision of determination in the horizontal plane of points, located within a larger forest area in Brasov county.For this purpose 2704 point where measured using a GPS equipment. The precision of such measurements is affected by a series of factors like the forest canopy and the terrain orography. The coordinates of the points were obtained using the semi-kinematic method, Stop&Go with postprocessing, which has an average precision, acceptable in this field. The points were then grouped according to the following criteria: localization, forest formation, orography, exhibition (S-N, E-V), forest consistency (<0.7, 0.7-0.8, 0.9-1.0), tree age (21-40 years, 41-60 years, 61-80 years, 81-100 years, >100 years).The points have been processed using software AutoCAD Map 3D and specific modules of ArcGIS. Data have been processed using a statistical program, Statistica 8.0. The distributions were analysed using several statistical indicators (maximum, minimum, mean, standard error of mean, mode, frequency of mode, standard deviation, coefficient of variation).Accuracies obtained were analyzed both for each category as well as for combinations of 2, 3 and 4 factors.After analysing all the results obtained, it can be expressed the idea that, on the whole, the accuracy of determining the point coordinates in forest lands is relatively good and that there are rare cases where exaggerated values are obtained.

The author treats the particularities of land improvements area from the perspective of management science. This article aims to define the land reclamation works, specific issues and foreshadows some solutions and approaches from a managerial point of view meant to internalize the added value and competitive advantage. In the author's opinion, capitalizing the vast managerial experience from the last decades produced significant scientific accumulations regarding management of an organization based on concepts such as those related to performance, quality and environmental protection, etc . Therefore, a modern approach in tune with these requirements, makes the difference between a building well designed, efficient, economically profitable and one that is developing without perspective and without concern for control, performance and efficiency. At the end of the article the conclusion is that a quality management applied in the field of land reclamation works is a prerequisite for success. In order to achieve a higher performance there is a severe need for management. Therefore, management is the qualified process exercising the planning, organizing, coordinating, training and control without which you can’t provide decisions, so necessary, and, also, through which organisations from land reclamation domain are fulfilling their specific missions .

Loess is a deposit of wind-blown silt that blankets large areas of the continents. It is often light brown in color, consisting predominantly of quartz, feldspars, micas, and calcium carbonate. Geographically, loess is extensive in the North American Great Plains, south-central Europe, central Asia, and central East of South America. In Europe, loess deposits are common in areas that lie between the former Alpine and the Scandinavian ice sheets and in regions to the east associated with major river systems. In Romania, loess was described by Gr Stefanescu in 1895 and the aeolian origin of the loess was stated for the first time by L. Mrazec, in 1899. Loessoid soils are very common in Romania, mainly in Dobrogea, Galati, Braila; they are found over some 19% of the area (Popescu, 1965). The aim of this paper considers the main topics of loess distribution, different hypotheses of its origin and geological characterization of these problematic soils.

Romanian earthquakes since 1940 and 1977 have produced severe damages to a significant number of RC framed buildings whose plans were characterized predominantly by irregularities like flexible diaphragms, structural discontinuities or L or H shapes, among others. These conceptual characteristics contributed in a decisive way to the damage or collapse of buildings designed and built according to old seismic codes.On the other hand, European and internationalexperience of the past strong earthquakes during last decades shows that, in many urban areas besides many old building, there is a number of modern RC buildings that do not meet the requirements of additionally improved Codes for seismic resistant design. The paper presentssome types of structural interventions on buildings and solutions for determine the dynamic building response. On basis of dynamic response recorded for buildings, a methodology for analyzing the structural behavior of this typology of buildings by adequatesoftware for 3D seismic analyzing is presented. For this purpose non-destructive and geodynamic methods were used. The non-destructive methods are based on auscultation, ultrasound and percussion with Schmidt hammer, and the geodynamic methods are based on the GEODAS equipment with Microwave software.The results proved that the mass and stiffness is not always beneficial and also emphasizes the role of geometry on dynamic response of building.

This study has as its purpose finding and presentation of the most effective ways of improving and protection of the embankments afferent to national road 17 – Tihuţa Gorge, perimeter situated in Bistriţa-Năsăud and Suceava counties. The main causes leading to the destruction of land are represented on the one hand by natural setting’s characteristics of the perimeter: uneven relief with high pitch, heavy textured soil and damp climate, and on the other hand by misuse of land and deforestation. The prerequisite for improving these downgraded lands are restoration of the vegetation and resonable use of it, prerequisite on which the choice of the improving actions and works is based on. The improving actions are: usage restrictions (grazing ban), exploitation rules, perimeter security, the installation of panels, and the improvement works are: phytoimproving measures (afforestation), soil preparation and improvement works (fertilization and amendation works), soil arrange works (draining). Afforestation is the main path to follow in downgraded land contention. The actual surface intended for afforestation from this perimeter Tihuţa-Colibiţa is 80% of downgraded lands from this perimeter.

Soil erosion is one of the greatest problem in agriculture, forestry and town-planning. Due to the continuous population growth towns are in a complex process of expansion, but when town expansion meets extreme deep soil erosion phenomena, this impediment is not only economical but also a social one and that is why gullies must be studied and monitored. This study is based on finding the technical data which defines the gully located in Cluj-Napoca in the La Cariera area and giving the solutions in order to stop the erosion, stabilize the gully and forecast its future behavior. The gully studied in this article is situated in the vicinity of the city of Cluj-Napoca and it is particularly important because in 10 years the city boundaries will overpass it and so these soil erosion phenomena must be integrated in the anthropic landscape.

In order to achieve the above mentioned target, one used the grid method to set up sample surfaces of 200 m2, realized the inventory of seedlings for each sample area and carried out the following measurements: the overall height of the seedlings, their growth recorded during the 2012-2013 vegetation season and their stem base diameter. The results of the measurements were statistically processed by calculating the coefficients of variation for different characters, as well as correlations between elements, the regression equations and by calculating the coefficient of regression. After analyzing the registered data, one concluded that all elements present a high and very high variability of the characters, due to the genetic diversity of origins, therefore the future of the newly installed stand is ensured and a proper and successful selection of tree can be performed + improving all analyzed characters, highlighting the elites and increasing the value of the stand. Following the performed correlations, one noticed a direct and distinct significant link between the height of seedlings and their stem base diameter. The differences between the average growth of the two analyzed seasons are differentiated on sample groups of sample markets. After carrying out the research and analyzing the obtained results, one can conclude the success and the opportunity of restoring old stands, as well as the ecological reconstruction of the area studied.

Polyaromatic hydrocarbons (PAHs) consist of more than two unsubstituted benzene rings. They can be found in all media and some of them are cancerogenic. Polyaromatic hydrocarbons (PAHs) are formed during incomplete combustion of organic matter (i.e., coal, oil, gasoline, diesel fuel, garbage, and tobacco). Increased concentrations of air pollutants caused by domestic heating, industrial activities, traffic and atmospheric transport in the city environments have been damaging air quality. Increased concentrations of air pollutants also cause health problems. Zonguldak region has an important place in Turkey because of having large coal fields and coal production. However Catalagzı Thermal Power Plant , Eregli Steel Plant and usage of coal and wood in the region makes a potential input for PAHs in high concentrations. In first stage of the study, calibration of PAH standards were made and PAH samples were collected periodically from 5 different sample collection points. In second stage of the study collected samples will be analysed. This study will be a preliminary study for literature with measuring the concentration of dry deposition of PAHs. In addition, data obtained from the analyses will be used in preparing density map of PAH concentration and this will help us for detecting the effective source of pollutants.

In this paper we intend to make a noise monitoring, produced by bandconveyors, monitorization necessary for finding solutions to combat noise. The main sources of noise pollution are tracked excavators with rotor and bandconveyors. For the urban areas and forested areas the tracked excavators with rotor is not a source of noise pollution. They represent a source of noise just inside the career, because of the way adjacent extraction steps, which is a natural barrier against the propagation of noise. The bandconveyor T111 from the Career Rosia of Jiu, which is transporting excavated material represents a source of noise pollution for residents of the village of Rosia of Jiu due to he's close location. Exposure to noise for long-term can cause adverse effects on health.

Due to the rapid development of the industry and also the settlements along the rivers, their waters reach wastes and even toxic elements that affect water quality characteristics. Pollution from industry is done at all levels: chemically, physically and biologically, thus affecting the normal development of flora and fauna. Changing water quality is achieved by altering the pH, temperature, water turbidity, but also enriching with organic materials content, thereby reducing the amount of oxygen in water, that favors the overgrowth of algae communities, resulting in eutrophication banks. The proposed research theme enroll in scientific concerns of international and national quality control and protection of surface waters against pollution and provides a comprehensive characterization of water quality of River Galda. To better highlight the influence of industry on the river Galda, his course was divided into four sectors from its source to its mouth, each sector comprising settlements developed along the watercourse and one food industry factory, except the first sector, that includes source of the river and a portion without settlements or other pollution sources. This section, first sector, provides information on the quality of river Galda water without the influence of anthropogenically induced pollution and is used as a reference section. To establish the water quality were used physical analyzes, chemical evaluation was done by determining the main parameters of the oxygen regime, parameters concerning nutrients and main ions existing in water. Evaluation of water quality in terms of biological and microbiological study was carried out by community diatoms in Phytobenthos and establishing ecological status of water on saprobic system, and the micro-biologically analyzed colonies of coliform bacteria , E. coli, Enterococci and NTG. As a result of analyzes was performed in framing quality classes stipulated in legislation of each sector analyzed and also established the ecological status of water in each sector, thus achieving a comprehensive evaluation of river water quality Galda, and evolution pollution from the source to the mouth, according to the sources of pollution.

The aim of the research is to create an complete, annotative (scalable), cross-platform library that can be imported and used in the most common CAD softwares (AutoCAD and it's variants, ArcMap, Corel Draw etc.). Currently, inserting the conventional map signs and symbols at scale in a CAD environment presents a problem to the average surveyor. There is no annotative complete library of these symbols present in any software, him having to resort to custom made librarys of incomplete list of the signs, markers and linetypes, third-party applications that are often incompatible to his CAD software of choice, or don't meet the specified requirement. In the cross-platform library were incorporate the following attributes to all the conventional signs used in different land survey domains: uniqueness (most important attribute), permanence, simplicity, ease of maintenance, flexibility and reference to geographic location. The content and format of the final product may be carried out in a variety of ways, depending on the scope and magnitude of the mapping projects (surveying, cartography, photogrammetry, landscape design, forestry planning etc). Regardless, the cross-platform library suits to how the mapping function is performed, specifically assigned to project plan development to serve as the organization’s blueprint.

The paper aims to present the generalities and areas of use of laser scanning and its use. Laser scanning technology is among the latest methods of collecting geodata. Is applicable especially in areas which use high precision 3D data. In brief, laser scanning principle is the following: sending a laser beam to measure the distance from the source to the surface or object searched. At the same time, is recorded the direction. By evaluating parameters are obtained information about a specific object on the surface. The laser can be set statically on the ground (terrestrial laser scanning) or a plane or helicopter (aerial laser scanning). For special applications, laser scanners may be located in a vehicle. The main product of laser scanning is a set of 3D coordinates of the points reflected called "point cloud", and with these automatic, semi-automatic and manual procedures, these points are classified by further processing.

There exists a very large amount of damaged buildings in Cultural Heritage in the old Centre of Bucharest. Common damages are related with structural deformations (lack of verticality, crashes, e.g.) and the degradation of the support (deteriorated materials, e.g.). Dense information is needed for both of them. Non-intrusive methods based in laser scans provide a 3d support with dense information with a low human cost. Terrestrial laser scanners deliver a dense pointwise sampling of an object’s surface. In many respects, laser scanning follows the same general surveying process as other instruments: data is collected in the field, adjusted to the appropriate coordinate system, and relevant features can be extracted to produce deliverables ranging from topographic maps, coordinate values, 2D or 3D CAD drawings etc.

The study conducted in this paper regards the comparative analysis of arc-to-chord correction between the Gauss-Kruger projected system and the Stereographic 1970 projected system. The correction is due to the fact that the measured direction between two points is actually a curved line, on the surface on a body such as an ellipsoid, that passes through these points. When projected onto a plane, the geodetic direction looks like an arc not a straight line. The angle that we compute from field notes is defined by the difference between two measured directions. Thus, the computed angle differs from the plane angle that we have to use when working with the State Plane Coordinate System. On the basis of the simple relation between spherical excess and arc to chord correction, formulas to compute the arc to chord correction for different map projections can be derived. In essence, research team aims to highlight the arc-to-chord differences obtained comparing the two projected system taken in consideration.

This paper presents the workflow for creating a virtual campus for the University of Agronomic Sciences and Veterinary Medicine of Bucharest from 2D GIS data. Basically, it follows the data integration based on ESRI templates and software specialised in 3D modelling. Over the years, GIS has evolved from a complex system for maintaining and analysing spatial and thematic information on spatial objects to digital representations of the Earth’s surface and related objects belonging to urban areas. Thus, the most common use of 3D geovisualisation today, is within public planning, architecture, environmental monitoring and landscape planning.
