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.

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.

The purpose of this study is to compare the precision of the geodetic points determined with GNSS methods using statistical calculations. Therefore I realized a statistical analysis of the results obtained after processing the data. The analyzed points are localized in the surroundings of Braşov City, Romania, being in number of about 557, of which 541 RTK, and 16 static determined points. Depending on the area, exposure and a number of other factors the precision of the points was different. The stationary time for the RTK determined points varies from minutes to seconds, and for the points determined using the static method the stationary period was much longer, namely around two hours. The stationary period on each point as well as the area in which the points are found directly influences the precision of the geodetic points coordinates.

The analysis of this images are made using a program called ArcGIS. With the use of this program was obtained six normalized differences indexes and two combinations of spectral bands; in which it is possible to see how the area of USAMVB Campus had developed in 26 years. Satellite imagery consists of images of Earth or other planets collected by artificial satellites. Interpretation and analysis of satellite imagery is conducted using specialized remote sensing applications. Remote sensing refers to the use of aerial sensor technologies to detect and classify objects on Earth (both on the surface, and in the atmosphere and oceans) by means of propagated signals (e.g. electromagnetic radiation). Satellite imagery is also used in seismology and oceanography in deducing changes to land formation, water depth and sea bed, by color caused by earthquakes, volcanoes, and tsunamis. Because the total area of the land on Earth is so large and because resolution is relatively high, satellite databases are huge and image processing(creating useful images from the raw data) is time-consuming. Depending on the sensor used, weather conditions can affect image quality: for example, it is difficult to obtain images for areas of frequent cloud cover such as mountain-tops.

This map is realised in order to represent the northen hemisphere of the sky vault using a right azimuthal projection, equidistant on the meridians, which contains over 700 stars having the magnitude less than 5, joined in 42 constellations. To achieve this purpose it was used a scanned map in order to draw the constellations limits and the zodiacal signs while the representation of the stars was possible using their equatorial coordinates from the FK 5 catalog. Regarding the textual part of the map this project shows how to create a Microsoft Access database and the method / the steps by which it is attached to the graphical map in a dwg. format. So, it is a fact that using digital maps is more advantageous than using the analog ones, because it is possible to store a much larger amount of information.

Presently, drought can be identified and monitored using a wide range of remote sensing methods. Over the last years, drought conditions were reported in several areas located in south of the country, in Giurgiu, Teleorman, Olt and Dolj counties. This study aims at identifying the drought affected areas and the effects of the drought on vegetation, based on satellite data acquired by Landsat. Both test sites covering the counties mentioned before are of major importance for agriculture. It is estimated that the agricultural area of the Giurgiu County was of approximately 238,000 hectares in 2012. The Romanian Plain has a rich and fertile soil that is very suitable for the cultivation of grain, sunflower, and technical and medicinal plants. Dolj County is located in the most fertile region of the Oltenia Plain benefiting by favorable climatic and soil conditions. Its total arable area is about 488,000 hectares, according to 2009 statistics. The county is covered in the southern part by large sandy areas and an impressive number of lakes formed either by flooding or precipitation accumulation. Remote sensing is an important tool for drought monitoring due to its capacity to observe large geographic areas using frequent acquisitions. Moreover, remote sensing offers the possibility to study archive satellite data and therefore to make better predictions for the future. The Normalized Difference Vegetation Index (NDVI), together with information on temperature and precipitation were used for estimating the drought index. In conclusion, the early identification of drought is important for mitigation efforts, while the monitoring of the drought effects contributes to more accurate crop yield estimations.

Afterwards, the map is inserted into the ArcGis 10.1 program, georeferenced and finally digitized by using elements such as: point (fountains, elevation terrain, etc.), lines (roads, electrical network, rivers, etc.) or polyline (villages, forrests, orchards, etc.).

3D Laser Scanning, also known as terrestrial LIDAR, has been commercially available for several years, providing a detailed, reliable, and accurate solution to many surveying and measurement problems, and has become well adopted for plant and facilities applications where accurate three-dimensional detail of complex facilities is critical for efficient design and construction projects. Terrestrial laser scanners deliver a dense point-wise sampling of an object’s surface. For many applications a surface-like reconstruction is required. The most typical example is the visualization of the scanned data. 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. This paper describes typical scanning project from field-to-finish, including common surveying applications.

The paper presents an easy method of creating small scale maps using an open source GIS program named “Quantum GIS” or “QGIS”, as well as open data freely available on the internet. The main focus is on transforming geographic information from a given coordinate reference system to an user defined one. This paper is concerned with both the application of projections defined automatically by the software, as well as the classic method of calculating the grid nodes using the map's equations. Both raster and vector data have been included in the process of producing this map. After transforming the necessary data, a brief layout design has been created in order to give the map an adequate form for plotting. The coordinates computed using the map equations have been overlaid on the coordinates given by QGIS in order to validate the results and verify the correctness of the map. All in all, the aim of this paper is to show the power of making high quality cartographic products and manipulating geographic data with the aid of open source GIS programs, given the precision achieved using such methods.

The introduction of cadastre in Romania as a matter of national interest and community obligation, in order to guarantee property rights, real estate market development, credit guarantee, etc., is dependent upon the digitisation of the basic cadastral plan at a scale of 1/5000 all across Romania. The technologies used are varied and the work is complex, involving large expenses. Within this context, the present work aims to determine whether and to what extent this cadastral plan can be obtained through the transformation or vectorization of the existing national orthophotoplans. The methodology is based on comparing the vectorised cadastral plan with the one obtained by level surveys, considered as a reference, and applied to six units (land areas) located in two different places. Comparisation has focused on the main stages of the vectorization process, namely on easily identifying parcels (property estates) and tracking their borders, on markings positioning accuracy, on surface errors that may arise in relation to real errors, and on aspects regarding performance, including hardware and software logistics. The results are good, fully satisfactory, suitable for practice in many categories of surveying projects and particularly advantageous in terms of performance that is ensured with minimum equipment. Some difficulties arise only in special cases on site, when additional evaluations and monitoring is required.

The paper is aimed to present the facilities of using modern tools in establishing the regulation of the urban development of an industrial area from Braşov, theMarubarea which includes also the Tractorul Park. The Zonal Urban Plan creates a framework for a coherent development of a consumer service area, offices and a clean industry, by providing a series of objectives including permissions and restrictions. This plan is based on terrestrial measurements using different surveying methods, chosen so as to reproduce the land as closely as possible. The cadastral monitoring of this area and the main aim of the Zonal Urban Plan to reduce the level of pollution led to an analysis of the capacity of taking the pollutant provided by the industrial zone by each tree from the near park.The results of the pollution studies allow the issuing of limitations rules regarding the traffic from that area. Therefore the conclusions refer to the necessity of improving the air quality and also to the sustainable development and the conservation of the urban green areas from Braşov.

The paper aimed to present the importance of Geographic Information Systems within the progress of various activities in terms of improving life conditions in the urban areas and also for promoting alternative methods of transportation such as bicycling. With this purpose in view it was submitted to examination a representative area of the capital, regarding the road network and its bordering estates. Through the instrumentality of Geographic Information Systems it was given the opportunity of inventorying them while creating a specific date base able to serve as a decisional support for the local public administration authorities. Given the fact that the textual information accompanies the graphic data it was easily established the way in which the transport roads could be adjusted so that they could insure the safety of all of the traffic participants.

Quantifying the impact of environmental factors in a mining area involves a large number of monitoring points and cover a large area of land. The quality of environmental factors we deduce in several ways, like surveying or analyzing the samples in laboratory that requires many time and in many situations, unjustified high costs. This paper’s purpose is to subject to attention a method that uses the new technologies in the remote sensing field in order to obtain secure information and low costs. This technologies are using in the same time GIS systems that are particularly useful in creating, analyzing and processing geo-spatial information. Implementing this techniques I suggest that we can control and prevent the impact caused by mining activities, we can improve the exploitation techniques and the most important, we can assure the safety of the employers.

This paper has as main purpose the determination of the small water catching areas using the scientific method. This method is applied for the Voinesti water catchsituated in the west extremity of the sub-Carpathian curvature. With this method the most important parameter is the one referring to theflowing coefficient.The global flowing coefficient is determined as an weighted average of the partial flowing coefficients corresponding to the different surfaces. This depends on the type of vegetation, on the soil type, and the inclination of the ground. GIS implementation for calculating the maximum flow by using the scientific method was made with a soft that functions under Arc Desktop 9.3. The results obtained were compared utilising the reduction method.

Our project consists in studying the possibilities of increasing the degree of automation in using prisms, measuring with a Total Station, with the purpose of increasing the efficiency of measuring. Basically the project presents an automat-tripod for the prism, which will automatically verticalize the prism pole, bringing it in the correct position for measuring. The automat-tripod has 2 gravitational sensors, a microcontroller and 2 motors that extend the 2 legs of the tripod in order to realize the verticalisation of the pole. Realizing this invention would lead to minimise errors produced by incorrect position of the prism in the moment of the measurement, and also, in case of using more than one prism, a technician can manipulate more prisms on automat-tripod, which means increasing work productivity.
