Assessment of heating degree-days factor (HDDF) for building-oriented climate zoning in Türkiye

ABSTRACT In this study, a novel heating degree-days factor (HDDF) is proposed to determine the optimum facade design for buildings in Türkiye as a function of both cooling degree-days (CDD) and heating degree-days (HDD) data. For this purpose, the HDDF (HDD/(HDD+CDD)) is defined as the ratio of the heating degree-days of a region to the total heating and cooling degree-days. Firstly, the HDDF values of all provinces in Türkiye are calculated by using meteorological data from 81 meteorological stations covering the period 1991–2022, and HDDF performance is evaluated. Then, the building-oriented climate zoning is realized based on the HDDF values. Moreover, historical trends of monthly and yearly average HDD, CDD, and HDDF values are revealed and yearly HDD, CDD, and HDDF maps were created using the ArcGIS program. According to the results, HDDF values in Türkiye varied between 0.4519 and 0.9998, and HDDF values between 0.9 ≤ HDDF ≤ 1 cover 46 out of 81 cities in the country and span a broad area across the country. The findings suggest that if global warming continues at the current rate, cooling energy demand in the residential sector will dramatically increase in the future, while heating energy demand will fall in Türkiye. This indicates that domestic energy consumption regulations would require modification. The building-oriented climate zoning resulting from this study is unique to Türkiye and can aid engineers, architects, and policymakers in building energy efficiency programs, studies, regulations, and standards.

Water reservoir techniques using remote sensing and GIS: a literature survey

Abstract The issue of storing flood waters caused by rains and river floods is very important to address the problems of drought. This study reviewed the latest research to address the problems of water scarcity and conservation with advanced methods. these study methodologies range from employing Geographic Information Systems Programs to handle and analyses remote sensing data to incorporating contemporary techniques to enhance morphometric analysis, where researchers employed various analytical techniques. To determine if these watersheds are appropriate for storing water, some studies have preferred Multi-Criteria Decision-Making models (MCDM), more especially the fuzzy analytical hierarchy (FAHP) Fuzzy Analytical Hierarchy Process. Others have employed techniques for hydrological analysis, such as the ArcGIS program’s Arc hydrology tools. Researchers reached a consensus regarding the fundamental parameters required for morphometric analysis in the demarcation of watersheds, notwithstanding methodological variances. Additionally, many researchers have argued the importance of using the Shuttle Radar Topography Mission Digital Elevation Model (SRTM-DEM) mission and the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER DEM) in morphometric and hydrologic studies.

Effect of Atmospheric Mixing on Spectral Reflectivity in Sentinel Images of Baghdad Province

The lowest layer of the atmosphere is called the atmospheric mixed layer, characterized by small-scale, irregular air motions defined by winds that change in speed and direction. Aerosol radiative effects impact the atmospheric boundary layer (ABL), which holds most aerosols in the lower atmosphere. Aerosol absorption and scattering both lower the quantity of solar energy that reaches the ground, which has an impact on the spectral signature of the land coverings. In this study, 51 locations in downtown Baghdad were chosen for four different types of land cover (water bodies, farms, open areas, and residential areas) for Sentinel 2 satellite imagery, and the time the pictures were taken was 8:00 am ( 22 March, 22 June, 20 September, and 22 December) 2021. Their spectral reflectance was calculated at the NIR band using a mathematical equation in the ArcGIS program for Sentinel 2 satellite images that had been processed and analyzed. Also, atmospheric boundary layer height and solar radiation values were downloaded for the same date as the satellite images and compared with the spectral reflectivity values of the land covers(agriculture area, residential area, open area, and river) and knowing the effect of the mixing layer and solar radiation on the spectral reflectance values. The highest value of spectral reflectivity, mixing layer height, and solar radiation was in June at (0.065, 1965.524629, and 897.7088) respectively. The spectral reflectivity of plants at near-infrared (NIR) was higher than the rest of the earth’s features because plants reflect near-infrared radiation and absorb the red and blue parts of the spectrum.

Ландшафтно-экологическое территориальное зонирование (на материалах Акмолинской области)

Introduction. Modern human activities in nature are subject to increasing regulation and restrictions, which should be reflected in systems for the use of natural resources, primarily in agricultural production. The problem under consideration is of particular relevance for the regions of Northern Kazakhstan, since the natural landscapes of the region have been radically changed and transformed into natural and agricultural complexes with a disturbed landscape-ecological balance.From the point of view of modern natural science, the organization of the rational use of rural areas should be solved by applying a concept based on the landscape-ecological approach. The purpose of the study. Territorial zoning of the agricultural landscape to optimize the use of agricultural land based on the landscape-ecological approach. Research methods. Cartographic materials used as the basis for the creation of diagrams and design developments, obtained on the basis of data from the virtual information system of the land cadastre of the Republic of Kazakhstan and processed using the ArcGIS program. Research results. Based on materials from the steppe zone of the Akmola region of the Republic of Kazakhstan, an analysis of landscape conditions and ecological stability of agricultural landscape systems was carried out. Analysis of territorial landscape zoning allowed us to conclude that the predominant part of the field landscapes of the steppe eons of this region is occupied by natural-territorial complexes of watershed spaces and watershed slopes, and the most common form of relief is slope surfaces. Ecological zoning of agricultural landscapes in the Akmola region revealed that the most common agricultural landscapes are characterized by weak stability and unstable agricultural landscapes. The article proposes a methodology for territorial zoning of agricultural lands on a landscape-ecological basis in the conditions of the Akmola region. It includes the following procedure: drawing up a landscape map. identification of homogeneous ecological zones; agrolandscape microzoning. As a result of research at the research object, a scheme of territorial landscape-ecological zoning for land use of agricultural formations was compiled, which is based on taking into account the paradynamic landscape structure of steppe landscapes and the degree of their anthropogenic transformation. At the same time, relatively homogeneous landscape-ecological microzones were identified, within which the elementary landscapes of the steppe catena were differentiated according to measures that stabilize the stability of the agricultural landscape. Conclusions. 1. On the territory of the Akmola region, natural landscapes have been transformed into agricultural production modifications. with a low degree of sustainability, requiring measures to maintain landscape-ecological balance. 2. The methodology for territorial zoning of steppe agricultural landscapes should be based on taking into account the paradynamic landscape structure of steppe landscapes, i.e. its catenary device. 3. Application of the results of territorial landscape-ecological zoning in design developments for the use and protection of land will allow the selection of optimal directions that ensure the sustainability of agricultural landscapes.

Cellular Phone Number Tracking System Based on ArcGIS and Google Maps

Over 4 billion individuals are projected to own a mobile device, with smartphone use continuing to rise around the world. Associated with this trend is the collection and usage of location information provided by these devices. The procedure for tracking and evaluating a mobile phone number is crucial for crime and terrorist attacks preventing concerns, especially in countries with deteriorated security conditions. The locational tracking information can enable real-time operational awareness and can save people's lives. In this aspect, the Geographic Information System (GIS) system is frequently used to provide intensive spatial information along the tracking process. This research aims to examine, follow up on, and trace a certain person's phone number inside a certain area using a combination of ArcGIS and Google Maps application software they are programs used to track and determine locations through the use of various types of coordinates, including latitude and longitude. In the ArcGIS program, there are several methods and algorithms used in various fields, including (locating people, determining tourist places, determining water and sewage networks, forecasting in the event of storms or floods, and many other areas), an example of these methods in the program is (Kriging method, Idw method, Spline method) and many other methods, each method is used for a specific purpose and field. In this research, the kriging method was used, which is a design algorithm that is used in many analysis and tracking processes and gives clear and accurate results. The process of determining locations in the maps used in the search depends on taking the longitude and latitude coordinates and downloading them to those maps. The maps that have been worked on in the research provide a set of basic concepts adopted in the process of tracking a particular person’s phone number, such as (the person’s location, the numbers connected to him, and the duration of a call to numbers in his contact list). The tracking system used is tested by creating a virtual contact list for a specific person’s phone number and making use of all the data in the contact list and applying it in the ArcGIS program, knowing that the duration of the contact list used is 9 months (from January to October 2021). The obtained results are analyzed and sorted in different ways to provide a wide model of the locational communication and movement activity of the tracked person. They showed that the system is efficient and can be applied to enhance the security in Iraq for tracking suspected people in crimes like terrorism, kidnapping, drugs, extortion … etc.

PREDIKSI KERENTANAN EROSI DAN SEDIMENTASI DAS SEMARANG TIMUR

The East Semarang watershed is an area with diverse land conditions and the majority of the upstream and downstream areas are converted into settlements. This results in an increase in the rate of erosion which erodes the land and causes sedimentation in the downstream watershed. The higher the erosion rate, the higher the sedimentation, therefore the prediction of the erosion value is important as an indicator to recommend natural resource conservation activities. The purpose of this study is to predict erosion and sedimentation rates, and to recommend good conservation methods in an effort to reduce soil erosion. Land erosion analysis was obtained from the overlay of erosion parameter layers with the help of the ArcGIS program using the USLE (Universal Soil Loss Equation) method. Not all of the eroded soil surface in the watershed will be transported to the river, but some will settle on the watershed surface due to the interaction between the flow and the watershed surface. Sediments carried by measured river flows at the outlet were analyzed using the SDR (Sediment Delivery Ratio) method. Then it can be known the amount of sediment per year in the East Semarang watershed or by the term SY (Sediment Yield). Based on the calculation of land erosion in the East Semarang watershed, as big as 816,910.81 tons/year, which resulted in a total sedimentation of 4,641.39 tons/year. Erosion hazard classifications vary from very light to very severe, with the majority of the class being very severe in the upstream region with an area of ​​7,003.55 Ha. The recommendation proposed to overcome or reduce erosion is technical conservation, namely terracing and check dam techniques.

Climate Change and Its Impact on The Expansion of The Phenomenon of Sand Dunes and Desertification of Agricultural Lands in Iraq for The Period 1984- 2022 (Governorates of Al-Qadisiyah, Al-Muthanna, and Dhi Qar)

Background: The present research aims to investigate the relationship between the phenomenon of desertification of agricultural lands and the expansion of the phenomenon of dunes in Iraqi Mesopotamia (central and southern Iraq), the phenomenon of global climate change, and the regional policies of the upstream countries neighboring Iraq. Method: The study uses, a monitoring process carried out using the data of satellite images of the Landsat series, for the period from 1984 to 2022, by ArcGIS program, with the tool of supervised classification. Results: Obviously, the danger of climate change and its effects on Iraq is shown in the results of this study, which showed that the fertile agricultural lands that were deserted constituted about 45% of the total lands until July 2022, including (16.67% of the total region) dunes or heavily decertified lands. The percentage of cultivated agricultural lands has deteriorated to 42%, a very serious decline compared to 1998 when the rate was more than 80%. Moreover, the most dangerous environmental situation right now is represented by the loss of more than half of its water bodies, as it currently (2022) constitutes only 12.47% of the study area, while it represented 26.9% of the study area in 1984. Conclusion: Based on the study results, we find out the annual precipitation rates are the climatic factor strongly affecting, the decline or expansion of the phenomenon of dunes, besides the neighboring country policies (Türkiye and Iran)

The Accessibility of Public Transportation Stops: Istanbul Case

The study emphasizes the importance of creating a sustainable public transportation system that people can use comfortably. This sustainable transportation approach aims to deliver transportation plans focused on people, society and space. Developing public transportation systems that contribute to social equality by appealing to all segments of society and reducing traffic density has become one of the main objectives of transportation plans. Ensuring the accessibility of public transportation stops is a crucial aspect of achieving this objective. In this context, the study examines the accessibility of public transportation stops in Istanbul. For the accessibility measurements of public transportation stops, the study uses the Service Areas Analysis tool in the ArcGIS program's Network Analyst extension, a geographical information system-based software program. The analysis results indicate that approximately 90% of the population can reach the stops of rubber-tyred public transportation types (one of the public transportation types in Istanbul) within a five-minute walking distance. However, the ratio of the population that can reach rail system stations and maritime transportation piers within a five-minute walking distance is only approximately 3%. Accordingly, it can be seen that the Istanbul transportation system depends heavily on the rubber-tyred public transportation system.

Monitoring Changes in the Spectral Reflectivity of Baghdad City and the Impact of the Atmospheric Elements on it using R.S and GIS

Abstract Climate change in recent years has greatly affected the distribution of ground covers. Monitoring these changes has become very easy due to the development of remote sensitivity science and the use of satellites to monitor these changes. The aim of this research is to monitor changes in the spectral reflectivity of the Baghdad governorate center for the month (March, June, September, December) of the year 2021 using remote sensing and satellite images Sentinel 2 and knowing the climate imact on them. Fifty-one samples were selected for four types of ground cover (agricultural land, water, buildings and open space) and their spectral reflectivity was calculated using satellite images. Sentinel 2, where it was processed and analyzed, and then the spectral reflectivity values were calculated using the ArcGIS program. The effect of climate on the spectral reflectivity comes through its impact on the ground covers and thus changing the spectral signature of them. The relationship between temperature, spectral reflectivity, humidity, spectral reflectivity, and knowledge of the type of the relationship between them by means of mathematical equations. The results showed that the spectral reflection of the plant at the near-infrared beam has the most change than the rest of the ground covers.
