The Geographic Information System for Public Administration Regarding the Updating of Green Cadastre. The Case Study of Bucharest

Author(s): George Laurenţiu Merciu,Vlad Păunescu,Sabina Plăvicheanu / Language(s): English Issue: 20/2016

The purpose of this study is to highlight how the Geographic Information System provides permanent access to the updated database and green spaces cadastral map of a particular administrative unit. Green Cadastre emerged from the necessity of creating a management system for green spaces and existing tree species in different administrative units, taking into consideration that the vegetation experiences a dynamic development and structural changes that can be reflected using different GIS applications. Inventory of green spaces was twofold: quantitative (the number of specimens per species, per parcels, quantitative attributes: height, trunk diameter, tree crown) and qualitative (phytosanitary condition of trees, trees belonging to the category of protected species).The result of the study lies in creating a digital map (GIS structure) that contains the distribution of compact green spaces and that emphasizes all green spaces features.

Applications of Fractal Geometry in Morpho-Hydrographic Network of the Danube Delta Potamology

Author(s): Iulian Nichersu,Iuliana Nichersu,Marian Mierla / Language(s): English Issue: 20/2016

Fractal geometry is a tool in the analysis and interpretation in Potamology. Delta, is a typical case of alluvial river that occurs at the mouth of the great rivers loaded with a large amount of silt and opens into smooth waters, usually saline (seas and oceans) which has shallow waters and a shelf extended where tides (in most of the cases) are of low intensity and where currents coastline, with different meanings are weak, allowing the appearance, submersible or on surface of bars or a flat surface cone of dejection on which the river it spreads its waters in a web of streams, canals and lakes.A fractal is a geometric entity which, in its spatial development, is multiplying more and more on a smaller scale. An essential characteristic of fractals is that if you look with a magnifying glass, any part thereof, is reproducing at a smaller scale, the figure of the whole fractal. Fractal Analysis of the mouths of the Danube show a particular hydromorphological dynamics with specific mechanisms important for the exchange of energy and matter.The high degree of complexity of the Danube course determines the occurrence of several degrees of freedom in the course of the bed, reflected in an intense development and decreased predictability.On the other hand, the fractal dimension analysis of morphologically homogeneous sections of the course, emphasizes the geometric homogeneity of the lower Danube by similar values thereof.As engineers and scientists, we have become aware that water management involves a holistic and integrated view of a number of distinct systems that would previously have been dealt separately, and consequently there is a need for collaboration with experts from a number of other disciplines. Also we have to take into account the requirement of a range of stakeholders who have a direct interest in Danube Delta ecosystems functions. We have to note the Danube Delta water circulation (DDWCS) system deal with very complex interactions that are not immediately apparent. Simulation modeling has therefore become an important tool in order to understand the behavior under changes to various boundary conditions or internal conditions, such as parameters or even functional representations of different identified phenomena.

Consideration on Hydraulic Reabilitation of Accessible Wastewater Collectors

Author(s): Cristian Florin Scripcariu,Mihail Luca / Language(s): English Issue: 20/2016

Accessible sewer collectors in service present a high degree of aging. Rehabilitation of accessible collectors can be differentiated by size and type of wastewater transported. Accessible sewer collectors (large and circular, ovoid, bell or mixed cross section) present specific measures for rehabilitation. Rehabilitation Technology can be with or without digging ditches. Accessible collectors may be rehabilitating with inner and outer works. Hydraulic rehabilitation requires flow parameters analysis for modified geometric sections. Hydraulic rehabilitation requires the analysis of collector walls roughness and its influence on the flow velocity. Research has indicated important changes to the flow section due to silting and hydrodynamic erosion processes. The flow sections were geometric transformed from curved shapes to mixed shapes (curves and lines).The changes of geometrical cross section caused the decreasing of velocity and transported flow by about 15 ... 28%.

Analiza digitală a reprezentării cartografice a orașului Sebeș din 1769

Author(s): Andrei Nacu / Language(s): Romanian Issue: 27/2019

In the first decades following the annexation of Transylvania to the Habsburg dominions, the Austrian military engineers produced a series of topographic plans representing the Saxon cities of Brașov, Sibiu, Mediaș, Bistrița and Sighișoara. In the case of Sebeș, the smallest urban center of the Transylvanian Saxons, the first cartographic depiction was only completed in 1769, during a general survey of the seat [administrative subdivision] of Mühlbach/Sebeș. This limited survey preceded the mapping of the entire Grand Principality of Transylvania (First Habsburg Military Survey), which took place between 1769 and 1773. The article presents the analysis of the 1769 cartographic representation of Sebeș using the open-source software Quantum GIS 3.4. After a scanned copy of the map was georeferenced and digitized, the investigation proceeded with a comprehensive description of the historical topography of Sebeș. We examined the roads, the hydrographic network, the inner city with its Medieval and Early Modern fortifications, the churches and cemeteries, the suburbs, the vineyards, gardens and orchards, as well as the mills and dams on the Sebeș river.

Topografia urbană a oraşului Brăila în lumina unor surse cartografice inedite de la sfârşitul secolului al XVIII-lea

Author(s): Mariana Şlapac / Language(s): Romanian Issue: 27/2019

The oldest published plans of the Danube city of Brăila are „The plan of the Braila fortress, as it was in 1788–1789 ...,” created by the Austrian officer Johann von Vermatti with the help of scouts, and the fortress plan for 1819, developed by the Ottoman military engineer Seyyid Ömer. Nevertheless in both cases one can notice some geometric distortions between the city and fortifications. Their proportions and dimensions appear to be much more accurate in the other two plans of Brăila, recently found by the author in the Russian State Military Historical Archive of Moscow. The first cartographic document as „The plan of the Brailov fortress ...” was drawn in 1770 by conductor Ivan Sobolev, and the second one as „The plan of the Brailov fortress with indication about the same Vorstadt ...” was taken in 1775 by engineer-captain Mark Severinchik. Both these plans record the topographic situation of the city during the stay of the Russian troops in Brăila for 1770–1774. It can be seen that the city's road network is organic, non-geometric and gradually developed in time. The direction of the streets is determined by the configuration of the Danube riverbank, transit transport arteries, and by an important attraction element which is the main building of worship with small streets leading to it. Thus, this forms a zone with a radial structure in this place. The built-up area, divided into „islands” of various forms, reaches the non aedificandi zone of the fortress.

Descoperiri în arhivele de la Moscova: planuri necunoscute ale orașului Iași

Author(s): Laurenţiu Rădvan,Mihai Anatolii Ciobanu / Language(s): Romanian Issue: 27/2019

Research into the Military-Historical Archive in Moscow has allowed the discovery of new plans for the city of Iaşi, i.e. two versions of already known plans and two unknown plans. Comparative analysis led to the re-dating of one of the plans, which had not been drawn in 1790, as previously thought, but in 1770–1771, when General Rumyantsev, in charge of the Russian army involved in the Russo-Turkish War of 1768–1774, was stationed in Iasi with five regiments. This plan includes new information about the palace of the prince, the city's fountains and aqueducts, churches, houses, streets and bridges etc. Additional useful data is provided by a new version of the 1789 plan, but mostly by two unknown plans, both made during the Russian occupation of 1828–1834. The 1828 plan is special because it is the first to apply the Lehmann method of graphic representation by hatching (slope hachures), which is why its cartographic perspective is superior to that of the previous plans. This is also the most comprehensive plan so far, giving researchers a much wider perspective on the topography of the city and its surroundings.

Modern Methods for Spatial Urban Planning

Author(s): Ana Cornelia Badea,Gheorghe Badea / Language(s): English Issue: 27/2019

Urban planning involves functions, scales, sectors, and stages and the main functions of urban planning can generally be classified into general administration, development control, plan making, and strategic planning. Currently, the focus is on creating smart cities with increased functionality and on sustainable regional urban systems, with a positive economic impact. Both decision makers involved in urban planning, as well as local and municipal councils, can use the application of modern 3D planning methods to obtain the overall image of urban development. Traditionally, the information management process for local urban projects has been unidirectional and manual. GIS provides planners, surveyors, and engineers with the tools they need to design and map the area of interest. We highlight the workflow applied in an urban area through using, defining or creating of 3D Basemap, Zoning Types, Overlay Types, Building Types, Space Use Types, Project Status Types, according with the general urban plan, focused on the GIS instruments.

Methodology for Identification of Lakes Destined for Liquidation in the Republic of Moldova

Author(s): Vasile Grama,Ana Vlasenco,Agostino Avanzi,Tommaso Dominato / Language(s): English Issue: 27/2019

In the RM more than 6000 ponds and reservoirs have been built. The lifespan of them is usually 40-50 years. Considering that most of them were built in the years 1960-1980, many of them have an expired exploitation period and the others are at the limit of the exploitation period. Estimates show that, due to siltation the volume of reservoirs have decreased by an average of 0,50% per year. In result the ecological flow for the rivers, in special for the small rivers is critical. The purpose is to define the Criteria and a repeatable Methodology for lake liquidation and strengthening the capacities of the Moldovan Institutions to achieve a better management of the water and sanitation of the key stakeholders, improving their performance in implementing water and sanitation services in a sustainable, efficient and equitable manner. Based on the knowledge of the territory of the whole Republic of Moldova the following list of Criteria is used: lake size; safety condition; socio-economic development; ecology and environment. The methodology is mainly based expert judgment on GIS modelling involving geoprocessing of some specific parameters criterion by criterion. A Multi-Criteria Analysis is used to transform in “accumulated scores” the assessment done for each criterion in order to identified the possible lake to be liquidated.

Contribution on the Adduction Pipes Cadastre for Potable Water

Author(s): Mihail Luca,Iustina Lateș,Loredana Crengăniș / Language(s): English Issue: 27/2019

The adduction pipes are a complex of constructions and installations with the role of transporting the water from the catchment to storage tanks, pumping stations, treatment stations etc. The location of adduction pipes involves a number of problems regarding maintenance, repairs, rehabilitation and modernisation. Adduction pipes have large lengths (tens and hundreds of km) and are located on a land with different property types. The property change on the adduction pipes site in the last 100 years requires a detailed analysis of the cadastre of these objectives. The paper aims to highlight problems such as: defining the owner of the site; delimitation of the sanitary protection area and cadastral classification; the transition way of the site from private property to the property of the water-sewage operator; obtaining real estate and urban water data necessary to monitor the operational process; obtaining real estate data for drawing up the technical rehabilitation projects.

Gis application in analysis of erosion intensity in the Vlasina River Basin

Author(s): Uroš Durlević,Ana Momčilović,Vladimir Ćurić,Maja Dragojević / Language(s): English,Serbian Issue: 2/2019

This paper analyses the state of erosion intensity in the Vlasina River Basin, the right tributary of the Južna Morava River. To determine the erosion intensity (Z) and sediment production, the Gavrilović method was used, in combination with the bare-soil index (BSI), with the application of geographic information systems (GIS) and multispectral satellite imagery. An erosion coefficient of 0.31 has been identified in the territory of the Vlasina River Basin, which has an area of 1,061.72 km². The prominent vertical fragmentation of the relief, large amount of precipitation in the source parts, density of the river network (1.65 km/km2), which is above the average river network density in Serbia, as well as inadequate land exploitation, are the main reasons why it is necessary to monitor the erosion intensity in the Vlasina River Basin. The annual production of the sediment is 462,496.30 m³, while the value of specific sediment production is 435,47 m³/km²/year. This study represents the attempt to apply modern technologies to d1etermine the intensity of erosion in the Vlasina River Basin, and the results obtained could be used for more adequate management of land and water resources, sustainable planning of the forest ecosystems and environmental protection.
