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.

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.

Virtualising Space – New Directions for Applications of Agent-Based Modelling in Spatial Economics

Author(s): Marcin Woźniak / Language(s): English Issue: 347/2020

Due to enormous technological progress, socio‑economic science has gained new possibilities of investigating complex and not well‑known socio‑economic phenomena. One of the recent promising research approaches is agent‑based modelling (ABM) with connection to geographical (GIS) data. ABM is a bottom‑up research method concerning individuals that live and interact in the artificial environment. In this type of simulation, evolution of the whole system and macro‑level patterns results from individual behaviour of autonomous entities. Combining ABM with GIS data moves the simulation into the real geographical space. Applying this approach provides powerful possibilities of more realistic socio‑economic simulations concerning urban and spatial economics, sociology and psychology. Geosimulation also helps to answer questions about dependencies between geographical space and economic performances of modern cities. In this paper, a closer look at this topic is presented. We deal with the problem of implementation of GIS data into agent‑based modelling software. In the first step of our research procedure, we compare ABM programming platforms, then we chose three of them which provide GIS data support. In the second step, we implement OpenStreetMap GIS data for one of the districts of Poznań into these programming platforms. Finally, we compare the performance of ABM platforms regarding three major criteria: difficulty of programming, GIS data compatibility and available technical support. Our research is the first step in developing a complex socio‑economic urban system under the ABM paradigm.

Using GIS for Landslides Graphical Representation. Case Study in Cornăţel (Hârtibaciului Plateau)

Author(s): Gheorghe Roșian,Csaba Horváth / Language(s): English Issue: 1/2020

This paper it’s part of the present concern regarding the graphical representation of landslides. A very particular category of landslides is the glimee type. Of the territories in which they are frequently encountered, the Transylvanian Depression must be noted. Despite that these landslides are considered stable, since they occurred thousands of years ago, they were affected in time by various geomorphological processes. These include the recent (shallow) landslides, runoff on the slope, etc. For a correct graphical representation of both the old landslide and the current processes, which by their manifestation contribute to the genesis of new relief microforms, a GIS methodology was used. By using it, one can obtain both a graphical representation of various generations of landforms and can also make calculations allowing them to find out exactly their surface. This aspect has obvious practical connotations. As case study we used the landslide of Cornăţel, located in the south-western part of Hârtibaciului Plateau, an old glimee type landslide.
