Sports has an important role for the health of present societies and the next generations as an element of urban design. Sports facilities have strong effects on the social life in urban areas. The facilities supply the communication between the dynamics of the cities and generate synergy in the city life of people interacting with each other for improvement in their lives. Before the construction of the sports facilities, the planners must evaluate the type and size of them in terms of the population of the whole city and, the population of neighboring settlement areas, which use the facility. Entropy can be used as a criterion for the quantitative measure of spatial information on maps. In the study, the location of the sports facilities in Istanbul are compared by using the entropy as a quantitative criterion. As a result, the success of the location selection for the sports facilities in urban areas are estimated by using the entropy as a component. Metric entropy method and applications were carried out by a case study in the city of Istanbul for defining the spatial distribution of sports facility locations with the posts of people including "sports" and sports-related keywords on social media.
体育作为城市设计的一个元素,对当代社会和下一代的健康具有重要作用。体育设施对城市地区的社会生活有很大的影响。这些设施提供了城市动态之间的交流,并在城市生活中产生协同作用,使人们相互互动,以改善他们的生活。在建设体育设施之前,规划者必须根据整个城市的人口和邻近的居住区域使用该设施的人口,对其类型和规模进行评估。熵可以作为地图空间信息定量度量的标准。本研究采用熵作为定量标准,对伊斯坦布尔体育设施的选址进行了比较。最后,以熵为分量,对城市体育设施选址的成功与否进行了评价。以伊斯坦布尔市为例,通过人们在社交媒体上发布的包含“体育”和与体育相关的关键词的帖子,对体育设施位置的空间分布进行了度量熵方法和应用。

In real estate, mass appraisal is a very important subject in the valuation of two and more properties. It can be of benefit in a number of fields including taxation, banking transactions, expropriation, etc. The base problem is which criteria to use for mass appraisal. Because the number of criteria and the criteria themselves vary according to people, regions and countries, they are uncertain. They should be optimum in order to save on time, labour and cost. The aim of this study is to reduce the criteria by determining which ones affect the plot value. A survey which was answered by a total of 2,531 participants was conducted in Turkey. Principal Component Analysis (PCA), one of the criteria analysis methods, was applied to the survey data. The number of criteria was reduced to 14 with separation and to 30 according to the results of PCA. But they decreased in the model verification when criteria data for 558 samples were collected in the Konya study area. An index of the neighbourhood and locational features of these criteria was created by using GIS. Three models were established using Multiple Regression Analysis (MRA) and the performance of the models was examined. The prediction values and the market value were integrated into the GIS to compare the spatial distributions of plot values.
在房地产行业中,批量评估是对两种或两种以上财产进行估价的一个非常重要的课题。它可以在许多领域受益,包括税收,银行交易,征用等。最基本的问题是用什么标准来进行大规模评估。由于标准的数量和标准本身因人、地区和国家而异,因此它们是不确定的。为了节省时间、人力和成本,它们应该是最优的。本研究的目的是通过确定哪些因素会影响地块价值来降低标准。一项共有2531名参与者参与的调查在土耳其进行。采用标准分析方法之一的主成分分析(PCA)对调查数据进行分析。根据主成分分析的结果,分离后的标准数减少到14个,根据主成分分析的结果减少到30个。但在Konya研究区收集了558个样本的标准数据后,模型验证的准确性有所下降。利用地理信息系统创建了这些标准的邻里和位置特征索引。采用多元回归分析(MRA)建立了三个模型,并对模型的性能进行了检验。将预测值和市场价值整合到GIS中,比较地块价值的空间分布。

In recent years, the continuously operating reference station – Turkey (CORS-TR) system has been widely used in engineering and cadastral work in Turkey due to ease of use, low cost, and national legislative requirements. In this study, long-term Network RTK (Real-time Kinematic) data were collected under 10°, 20°, 30° and 40° satellite views using a different approach from previous work. In order to evaluate the positioning performance of the system, the measurements were undertaken at different elevation angles (open, partially blocked and extremely blocked) and by considering three different correction techniques (FKP, VRS and MAC), and the results were evaluated in terms of repeatability.
近年来,由于易于使用、成本低和国家立法要求,土耳其连续运行参考站(CORS-TR)系统已广泛用于土耳其的工程和地籍工作。在本研究中,使用与先前工作不同的方法,在10°、20°、30°和40°卫星视图下收集了长期网络RTK(实时动态)数据。为了评估系统的定位性能,在不同的仰角(开放、部分阻塞和极度阻塞)下进行了测量,并考虑了三种不同的校正技术(FKP、VRS和MAC),并根据可重复性对结果进行了评估。

USER-CENTRED DESIGN AND EVALUATION OF MULTIMODAL TOURIST MAPS 以用户为中心的多式联运旅游地图设计与评价
IF 1.9 Pub Date : 2019-10-01 DOI: 10.26833/IJEG.535630

User-centred maps are designed to provide users with the geospatial information they need primarily by their interests and thus more powerful support for their geospatial decision-making. In many cases, creating this kind of maps involves designing maps at multiple modes. Tourism is one of the areas that various kinds of maps both analogue and digital are used widely. Well-designed tourist maps can contribute to increasing the attractiveness of a region and the satisfaction of visitors. In this context, although some applications are available on user-centred multimodal tourist maps for web and mobile environments, there is no comprehensive study dealing with paper maps. Therefore, this article focuses on the design and production as well as evaluation of user-centred multimodal tourist maps for the analogue environment in the case of Kyrenia (Girne) district of the Turkish Republic of Northern Cyprus. The study consists of three main stages. In the first phase, a tourist geospatial database was established for the district of Kyrenia. In the second phase, user-centred multimodal tourist maps were designed and produced for three types of tourism, considering the prominent characteristics of the district in this respect. In the third phase, user evaluations were made. For this purpose, newly designed maps (as a group) and an existing tourist map were evaluated individually and comparatively by potential users of different gender, age and education characteristics by face to face survey method. Survey results showed that the user-centred multimodal maps are more preferable than the general tourist map.
以用户为中心的地图旨在为用户提供其主要兴趣所需的地理空间信息,从而为其地理空间决策提供更有力的支持。在许多情况下,创建此类地图涉及到以多种模式设计地图。旅游业是各种模拟和数字地图广泛使用的领域之一。精心设计的旅游地图有助于提高一个地区的吸引力和游客的满意度。在这种情况下,尽管网络和移动环境中以用户为中心的多模式旅游地图上有一些应用程序,但尚未对纸质地图进行全面研究。因此,本文重点关注以用户为中心的多模式旅游地图的设计、制作以及评估,以北塞浦路斯土耳其共和国凯雷尼亚(Girne)区为例,用于模拟环境。这项研究包括三个主要阶段。在第一阶段,为基里尼亚区建立了一个旅游地理空间数据库。在第二阶段,考虑到该地区在这方面的突出特点,为三种类型的旅游设计和制作了以用户为中心的多式联运旅游地图。在第三阶段,对用户进行了评估。为此,不同性别、年龄和教育特征的潜在用户采用面对面调查方法,对新设计的地图(作为一个群体)和现有的旅游地图进行了单独和比较评估。调查结果表明,以用户为中心的多模式地图比一般旅游地图更可取。

Land cover/use changes specially the forest cover changes affect the local surface temperature (LST) of the earth. In this study, a combination of remote sensing and GIS techniques was used to scrutinize the interactions between LST anomalies and deforestation in Sardasht County, NW Iran. The land cover/use change layers of the study area were extracted from Landsat satellite imagery based on Binary Encoding classification and change detection technique. The radiometric correction analysis were done for each Landsat image to derive LST map layers. According to the results, a descending trend in forest cover with a total 2560 ha decline in area and an ascending trend of about 4 degrees rise in surface temperature values on both forest and non-forest areas were detected in the study area from 1984 to 2017. The temporal and spatial analysis yielded high rates of reverse temporal correlation (-0.81) between forest areas and LST anomalies while the correlation value of 0.76 was found for non-forest areas and LST. The regression analysis of the values confirmed the correlation values to be trustable at 99 percent. It was also found that the deforested areas of the study area correlates with the LST rise spatially with a very high correlation measure (0.98) with which a tangible interaction of the parameters can be inferred.
土地覆被/利用变化特别是森林覆被变化影响着地球局部地表温度。在这项研究中,利用遥感和GIS技术相结合的方法,仔细研究了伊朗西北部萨尔达什特县地表温度异常与森林砍伐之间的相互作用。基于二进制编码分类和变化检测技术,从Landsat卫星影像中提取研究区土地覆盖/利用变化层。对每个Landsat图像进行辐射校正分析,得出地表温度地图层。结果表明,1984 - 2017年,研究区森林覆盖面积呈下降趋势,总面积减少2560 ha,森林和非森林地表温量值均呈上升趋势,上升幅度约为4℃。时空分析结果表明,森林面积与地表温度异常呈高负相关(-0.81),非森林面积与地表温度异常呈高负相关(0.76)。对这些值进行回归分析,证实相关值的可信度为99%。研究区森林砍伐面积与地表温度上升的空间相关性非常高(0.98),可以推断出参数之间存在明显的相互作用。

Istanbul, being one of the oldest and crowded cities in the world bridging the Asia and Europe continents, is ranked as the 15 th populated mega city among the 75 largest metropolitans in the world as a result of the rapid population growth since the year of 1950. The stated growth caused a significant need for housing, therefore new settlements have been built in and around the city threating water resources, protected areas, and sensitive lands such as agricultural areas, forests, wetlands in the city. As a result of these adverse developments, the Bosphorus zone, which has a historical and geographical importance for Istanbul, was declared as a protected zone for stopping the threat of unplanned urbanization along the Bosphorus. The Bosphorus area were divided in to two protection zones as Back View and Front View Zones by the laws in terms of the stated protection plan. The main goal of this study is to examine the changes in settlement areas in the protected zones of Bosphorus specifically in Sariyer District. In this context, Landsat imageries dated 2005 and 2017 were used to determine the urban sprawl during 12 years in the protection zone of Bosphorus. The results of the study introduced 10% decrease in the forest and green lands from 2005 to 2017 while 8% and 11% increase in settlements and the other land use classes respectively. In order to perform more detailed analyses of this change, a detailed study was performed for Front and Back View Zones of Bosphorus in Sariyer district using 2005 and 2017 dated IKONOS satellite images. The map of Sariyer district produced in 1960 was considered as the reference data source as well as image for detecting the changes in the study area during 57 years in two periods. The results of the study outlined that the settlements in the study area increased 173% and 142% for two periods from 1960 to 2005 and from 2005 to 2017 respectively. The increase in settlement areas caused a decrease in forests and green lands in the study area. In particular, the study introduced the illegal settlement area increase in the protection zones of the Bosphorus based on the Bosphorus Law No. 2960 in Sariyer District.
伊斯坦布尔是连接亚欧大陆的世界上最古老、最拥挤的城市之一,自1950年以来,由于人口的快速增长,伊斯坦布尔在世界上75个最大的大都市中排名第15位。上述增长导致了对住房的巨大需求,因此在城市及其周围建造了新的定居点,威胁着水资源、保护区和敏感土地,如城市的农业区、森林、湿地。由于这些不利的事态发展,对伊斯坦布尔具有历史和地理重要性的博斯普鲁斯海峡地区被宣布为保护区,以阻止博斯普鲁斯河沿岸计划外城市化的威胁。根据法律规定的保护计划,博斯普鲁斯海峡地区被划分为两个保护区,即后景区和前景区。本研究的主要目的是研究博斯普鲁斯海峡保护区内定居区的变化,特别是在Sariyer区。在此背景下,2005年和2017年的陆地卫星图像被用于确定博斯普鲁斯海峡保护区12年内的城市扩张情况。研究结果表明,从2005年到2017年,森林和绿地减少了10%,而定居点和其他土地利用类别分别增加了8%和11%。为了对这一变化进行更详细的分析,使用2005年和2017年IKONOS卫星图像对Sariyer区博斯普鲁斯海峡的前景区和后景区进行了详细研究。1960年制作的Sariyer区地图被认为是参考数据源,也是检测研究区域57年来两个时期变化的图像。研究结果表明,从1960年到2005年和从2005年到2017年,研究区域的定居点在两个时期分别增加了173%和142%。定居点面积的增加导致研究区域的森林和绿地减少。特别是,该研究介绍了根据第2960号《博斯普鲁斯海峡法》在萨里耶区增加博斯普鲁斯海保护区的非法定居点面积。

Rapid urbanization is a leading process for the global environmental problems such as climate change, massive loss of natural habitats, an increase of air, water, soil quality and social troubles. Within the scope of elimination of these effects, detecting, preserving and managing a strategically planned ecological network can provide ecological, economic, social and cultural benefits. Specially, connectivity of landscape patches in urban areas is an important factor for urban ecosystem cycle. Ecological studies under these circumstances are concentrated in urban areas and strategies are being developed to create green systems by establishing links between green areas. In this study, a method based on the graph theory has been proposed to create ecological links between important landscape patches in the Chennai City and the effects of the created system on the city has been discussed. Firstly, a comprehensive database is created for Chennai in the GIS. And then, important urban landscape patches and connectivity are detected with use of Conefor software that enhances the quality of landscape patches and ensures that landscape connectivity is sustainable. With this scope, we used integral index of connectivity (IIC) index and the probability of connectivity (PC) index that have been known to show an enhanced performance for urban habitat conservation planning and change monitoring applications. Ultimately, the resulting findings are mapped in the GIS environment, and the ecological, social and cultural impacts of the system are discussed based on international literature.
快速城市化是导致气候变化、自然栖息地大量丧失、空气、水、土壤质量增加和社会问题等全球环境问题的主要过程。在消除这些影响的范围内,发现、保护和管理一个战略性规划的生态网络可以提供生态、经济、社会和文化效益。城市景观斑块的连通性是影响城市生态系统循环的重要因素。在这种情况下的生态研究集中在城市地区,目前正在制定战略,通过在绿地之间建立联系来建立绿色系统。本研究提出了一种基于图论的方法在金奈市重要景观斑块之间建立生态联系,并讨论了所创建的系统对城市的影响。首先,在GIS中建立了金奈的综合数据库。然后,使用Conefor软件检测重要的城市景观斑块和连通性,以提高景观斑块的质量,并确保景观连通性是可持续的。在此范围内,我们使用了已知的连通性积分指数(IIC)和连通性概率指数(PC),它们在城市栖息地保护规划和变化监测应用中表现出更高的性能。最后,将结果映射到GIS环境中,并根据国际文献讨论了该系统的生态、社会和文化影响。

Within the scope of elimination of these effects, detecting, preserving and managing a strategically planned ecological network can provide ecological, economic, social and cultural benefits. Specially, connectivity of landscape patches in urban areas is an important factor for urban ecosystem cycle. Ecological studies under these circumstances are concentrated in urban areas and strategies are being developed to create green systems by establishing links between green areas. In this study, a method based on the graph theory has been proposed to create ecological links between important landscape patches in the Chennai City and the effects of the created system on the city has been discussed. Firstly, a comprehensive database is created for Chennai in the GIS. And then, important urban landscape patches and connectivity are detected with use of Conefor software that enhances the quality of landscape patches and ensures that landscape connectivity is sustainable. With this scope, we used integral index of connectivity (IIC) index and the probability of connectivity (PC) index that have been known to show an enhanced performance for urban habitat conservation planning and change monitoring applications. Ultimately, the resulting findings are mapped in the GIS environment, and the ecological, social and cultural impacts of the system are discussed based on international literature.","PeriodicalId":42633,"journal":{"name":"International Journal of Engineering and Geosciences","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44086998","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are temporary or permanent physical changes depending on time in earth surface. These physical changes named as deformation. The magnitude and direction of the deformation effect must be measured and controlled. The geodetic deformation network is established to determine the deformation movements and the deformation measurements are made. Then, the point coordinates are calculated used the free network adjustment. So, the different point coordinates were obtained according to measured time. The difference of point coordinate must be test to decide as significant or insignificant. Thus, the significance test based hypothesis test can be made. In this study, deformation network was established in Toybelen village of Samsun province and the deformation measurements were made periodically. The deformation network was consist of 14 points. This deformation network measured in two periods used the global positioning system. Evaluation was made using the Topcon program and point coordinates were obtained. Differences in point coordinates received and these differences were significant tested. The program written in the matlab program was used for this test. Finally, coordinate values compared in two periods and movement points have been identified.
地球表面有暂时或永久的物理变化,这取决于时间。这些物理变化称为变形。变形效应的大小和方向必须进行测量和控制。建立大地变形网,确定变形运动,并进行变形测量。然后,利用自由网平差计算点坐标。因此,根据测量时间得到不同的点坐标。点坐标的差值必须经过检验才能判断为显著或不显著。因此可以进行基于显著性检验的假设检验。本研究在三顺省Toybelen村建立了变形网,并定期进行了变形测量。变形网由14个点组成。这个变形网是用全球定位系统在两个时期测量的。利用Topcon程序进行评价,得到点坐标。接收到的点坐标的差异和这些差异进行了显著性测试。本次测试使用的是matlab程序编写的程序。最后,确定了两个周期内比较的坐标值和运动点。

Recently, a new interest in the social science community in location and a new "spatial social science" that crosses the traditional boundaries between disciplines have emerged. In this context, we will examine the usage of Geographic Information Systems (GIS) in the analysis of human resource management in the public sector. For this research, personnel and operational data of 957 Land Registry Offices in all districts of Turkey were used. These operational data were examined using different clustering techniques. By using tools of Geographic Information Systems to analyze public services, the distribution and condition of services can be understood much better. This study shows the first step to improve them and to allow for making better-informed decisions on where, when and what kind of resources to allocate in the human resource management in the public sector.

Coordinate transformation from one datum to another is the basic problem in geodesy. Generally, the problem may be expressed by converting coordinates in a cartesian coordinate system with defined origin provided by intersection of two axes into another system using mathematical equations. To compute the transformation parameters, sufficient number of coordinates of the common points should be known in two systems. The problem involves either 2D or 3D coordinate systems. Traditionally the commonly used model for coordinate transformation is the Least Squares (LS) method refers as to Helmert Transformation. This study aims to compare the performance of the spatial distribution and quantity of the common points in LS method for coordinate transformation problems. For this purpose, a geodetic network with 25 station points, whose coordinates are commonly known in two datum are used to compute the performance of the transformation parameters under the different scenarios. To compare the cases, the sum of the absolute coordinate differences provided by subtracting the original coordinates of test points from estimated coordinates by using transformation parameters. The results showed that increasing control points one by one to estimate the transformation parameters improve the results of the estimation and reliable transformation parameters have been estimated when a homogeneously distributed 8 points are taken as common points for about 1500 km 2 .
从一个基准到另一个基准的坐标变换是大地测量学中的基本问题。一般来说,这个问题可以通过用数学方程将直角坐标系中的坐标转换成另一个坐标系来表示,直角坐标系的原点由两个轴的交点提供。为了计算变换参数,需要知道两个系统中足够数量的公共点坐标。这个问题涉及2D或3D坐标系统。传统上常用的坐标变换模型是最小二乘(LS)方法,即Helmert变换。本研究旨在比较LS方法在坐标变换问题中公共点的空间分布和数量的表现。为此,我们使用一个包含25个站点的大地测量网,这些站点的坐标通常在两个基准面中已知,来计算不同场景下变换参数的性能。为了比较两种情况,使用变换参数从估计坐标中减去测试点的原始坐标所得到的绝对坐标差的和。结果表明,在以均匀分布的8个测点为公共测点的1500 km 2范围内,逐次增加测点来估计变换参数,可以提高变换参数的估计效果,得到可靠的变换参数。
