Abstract:
Nature was and remains an eternal companion of man, but at the same time, it is also a constant enigma. Man’s connection with nature is ancestral, and the need for this connection is constantly proven. Landscape design is the field where art (human creation) and nature meet, creating a field of endless possibilities in the development of outdoor spaces, but while the artistic side of the field is constantly improved and developed, sometimes the exploration of the natural side is left behind. The present study aims to identify and analyse the types of compositional lines that can be found in natural landscapes. For this, different photos from natural parks or Romanian reserves were selected and subjected to visual analysis. In the examined scenes, vertical, horizontal, diagonal, straight or sinuous lines (the most dominant) were identified, being suggested by tree trunks or logs, water beds or streams, paths, the topography of the land or the contour of the crown. Their properties, such as thickness or repetition, can provide diversity, animate a scene, and generate visual movement or invite further exploration. This work can serve as a basis for a more thorough study of natural landscapes and is relevant to landscape architects who support the use of natural style in their work or are interested in integrative landscape design for a better understanding of natural features, as well as researchers who want to explore the aesthetics of natural landscapes.

Abstract:
This study brings a rapid method to utilize the available open-source geospatial data in assessing the pedestrian accessibility to key public services/facilities. At this stage, we are testing the method in the case of Tirana, the capital city of Albania. Yet, the method is reproducible to other metropolitan areas around the world. Open street map (OSM) data and reference layers from Albanian National authority for geospatial information (ASIG geoportal) have been used as the raw material of the study. While the geospatial visualization, refinement, and analysis rely on the usage of QGIS software and the related plugins. QNEAT is the plugin that was used to generate the isochrones which indicate the spatial coverage of a certain service referring to the existing urban transportation/circulation network. The plugin enables the definition of different distance ranges. Our results show that certain public services serve to various amounts of the building stock at a gradient of walking distances. For example, more than 25% of the existing building stock has pedestrian access to caffes and pharmacies within a walking distance of 250 m. The same services serve to almost 90% of the same building stock within 1 km walking distance. However, services like banks are accessible only by 12.6% of the existing buildings within a walking distance of 250 m, and 67% at 1 km walking distance. The accuracy of the available geospatial data resulted to be vital for the reliability of the results. We conclude by highlighting the importance and utility of GIS-based methods of urban analysis in the processes of planning new public services in the city.

Abstract:
The systematic registration of real estate on the territory of a state represents the way to the rapid development of the market economy by reducing transaction costs, securing property rights, reducing or avoiding corruption and attracting investors. This work presents the way to create a systematic cadastre sector in the form of a case study, in accordance with the systematic cadastre procedures at the level of Romania, and its impact on sustainable development. In Romania, systematic registration is realised in the Eterra electronic database starting with the year 2015, together with the establishment of the National Agency for Cadastre and Land Registration (ANCPI) program 2015-2023. Registration is carried out exclusively at the level of the administrative-territorial unit (U.A.T.), respectively commune, city, municipality or at the level of one or more cadastral sectors, depending on the contract concluded between the executor and the local municipality. The procedures and stages of carrying out systematic cadastre works are regulated by Law number 7/1996 on cadastre and real estate advertising and the Regulation of July 9, 2014, on approval, reception and registration in the cadastre records and land register, as approved by the Order ANCPI number 700/2014. The financing of the program is made from three different sources: own revenues of the ANCPI in the amount of approximately 900 million euros, non-refundable external funds (European Union) in the amount of approximately 312 million euros, allocations from the budget of the units administrative-territorial through co-financing and is done free of charge for property owners.

Abstract:
The continuous development and the rapid economic growth of Timisoara municipality (western Romania) have contributed to the increase in transport needs. The number of motor vehicles registered by natural persons (125195), and the number of motor vehicles registered by legal entities (35303), results in one motor vehicle per two persons. To these figures are added the commuters, students and tourists who come by car to the city. Thus, the main cause of road traffic is the increasing number of vehicles, day by day. In order to maximize road capacity and speed up the pedestrians’ flow, traffic lights are used at approximately every intersection. As such, the proper use of traffic signals can lead to more efficient traffic management. Due to the evolution in time, technology comes to aid precisely to solve such problems and especially to streamline road traffic issues. Thus, the article presents the workflow that includes identifying the elements of a traffic light intersection, measuring, and processing them, in order to realize a layout plan that can be introduced into a GIS system to manage traffic lights in an intelligent manner. Using GIS (Geographical Information System) technology, the problem of road traffic can be solved appropriately and efficiently. Based on the main characteristics of urban traffic and the efficient, appropriate use of traffic lights, approaching, and treating the information according to the area, its spatial and geographical location through coordinates, GIS technology can be used to solve problems given by the zonal agglomeration of heavy traffic centres, or areas with peak hours. The fluidization of the traffic can ensure better circulation and aeration of the crowded areas and the avoidance of the congestion of some central arteries, especially during rush hours.

Abstract:
Data fusion and analysis of maps and remote sensing data collected from different spatial perspectives (ground, air, and space) at different times from the early 20th century to the present using different sensors were used to answer questions about glacier behavior and rapidly changing landscapes of Alaska’s southern Kenai Mountains. Expeditions to three fiords of the southern Kenai Mountains were conducted during the summers of 2004, 2005, 2006, and 2021. Each expedition used repeat photography to document glacier behavior and change, and landscape evolution at six Kenai Mountains glaciers, most located within Kenai Fjords National Park. Bear Glacier, Aialik Glacier, Pedersen Glacier, Holgate Glacier, Little Holgate Glacier, and Northwestern Glacier were studied and at a minimum, their terminus positions were determined for the following dates: 1909, 1950, 1961, 1973, 1990, 2004-2006, and 2021. Each glacier displayed unique asynchronous behavior. Since 1909, all displayed long-term terminus retreat. However, the timing for each glacier was unique. In 2021, Holgate Glacier was advancing, while the other five glaciers were retreating.

Abstract:
Eurasian Black Vulture (EBV) and Eurasian Griffon Vulture (EGV), while residents elsewhere, winter in Uttar Pradesh, India. Knowledge of the habitat and regulating factors is obligatory for protection and better management of these vultures. Therefore, different types of habitats were mapped using eight species distribution models. Presence records from field survey, published data and citizen science, and 23 bioenvironmental raster layers were the model inputs. Eighteen models were developed whose strength varied greatly. As per the performance indicators, GBM and GLM were found to be superior models for EGV. For EBV all models were acceptable. MARS, with good model strength, was rejected on the grounds of field verification. However, the Ensemble model, overall, was found the best. As per this model, good habitat was restricted mostly in the Tarai ecozone. The top two vital variables were NDVI, and bio13 for both the vultures. The most vital temperature variable for EGV was bio08 while bio09 for EBV. Tarai ecozone showed the largest expanse of suitable area for both the vultures followed by Vindhyan-Bundelkhand, Gangetic plains and Semi-arid ecozones. Among the two, EBV (49000 km2) had more suitable area than EGV (37000 km2). Agricultural areas were found to be largely unsuitable. As per land cover, good habitat was mostly confined in forests. For better management of these wintering vultures which need only roosting and foraging, it is proposed that destruction of forested habitat and decrease in foraging materials needed immediate attention and control.

Abstract:
The use of remote sensing indices in order to obtain information for vegetation distributions, heath and patterns is a popular practice with applicability at different scales of detail. The present article presents an example of using the Normalized Difference Vegetation Index (NDVI) and Change Detection method to identify the spatio temporal evolution of forest area in Târgu Lăpuș city, northern Transylvania, Romania. NDVI method is applied at different NDVI threshold values such as 0.1, 0.15, 0.3, 0.45 and 0.6. For the analyzed area, an area of 1.56 km2 with forest gain and 3.59 km2 with forest loss was identified. The advantage of using this method is the large time gap for which it can be done, in our situation being an analysis for the period 1983-2020 so that we can identify the trend of evolution of areas occupied by forests in a city where spatially built it often extends uncontrollably, affecting the degree of compactness of the forests and implicitly their protection functions.
