Keywords: Geographic Information Systems, Mitigation Phase of Disaster Management, Geographic Data Model, Data Requirement Analysis, Interoperability.

SUMMARY

Manmade and natural disasters have been increasing day by day and cause great human and properties losses. Hazard is a dangerous fact or activity that can leads to loss of life, health effects, social and economic losses. Vulnerability is a feature of a society that makes it susceptible to the destructive outcomes of the hazardous event. The interaction of hazard and vulnerability creates the risk of disaster. Mitigation stage refers to activities such as determination of disaster hazard and risk and avoidance of damages, prevention of its effects or minimization, taking measures to compensate inevitable losses. It is an intricate issue in the whole sequence of emergency management requiring full and quick collaboration between diverse actors in diverse sectors. Geographic Information Systems (GIS) will facilitate to diminish of calamitous results of disasters and protect lives and properties with dynamic use in mitigation phase of disaster management. For effective management of disasters as a priority, data requirement analysis were accomplished for mitigation phase of disaster management after determining disaster types such as earthquake, flooding, landslide, forest and urban fire. Developing an interoperable geographic data model is a new approach for Turkey that enables using the data corporately and successfully. This model are object-oriented model and based on ISO/TC 211 Geographic Information standards. The model is fully described with Unified Modeling Language (UML) class diagram and converted to Geographic Markup Language (GML) of OGC. The model compliant with Turkey National GIS specifications can be starting point for geographic data providers in Turkey to determine disaster risk that has significance because of the increasing of natural or man-made disasters. When data sets are produced with these standards, risk map will be produced effectively and data sharing will be possible between different actors.

GIS based Accessibility Assessment for Public Services: Istanbul Case

Ozan Arif KESİK, Arif Çağdaş AYDINOGLU and Deniz SAĞLAM, Turkey

 

[abstract] [paper] [handouts]

Key words: Geographic Information System, Accessibility, Transportation, Istanbul,

SUMMARY

The concept of accessibility is significant in accessing to many functions such as works, social facilities, and accommodation in developing urban areas. Transportation facilities and land use of a city affect the daily life of all the individuals dwelling in the city. Development of effective accessibility strategies makes the life of people in cities more habitable. The fact that number of vehicle owners increases result in many problems. Some of these main problems are environmental pollution, parking lot problems, traffic jam and accidents, physical inactivity and obesity.

Accessibility to urban functions must be analyzed and planned firstly in order to have livable cities. Understanding public transportation accessibility is important to encourage shifts to reduce car and using public transportation. There are 14.160.467 people living in Istanbul (Turkey) according to 2013 data. The number of travel is considerably high and private vehicles carry out most of these travels. Access to public transportation will pave the way for the decrease in the number of private vehicles in the traffic.

In this study, Geographic Information Systems (GIS) techniques were used to assess transportation accessibility. Network analyst techniques support determining zone-based, isochronal, raster-based accessibility assessment on transportation network. 9 different metro and train lines of Istanbul that 400 million people travel annually were analyzed as the case study. Thus, approaches for the effective use and planning of transportation infrastructure were examined to reach urban functions.

Abstract— Considering the increased number of vehicles every day, parking supplies should meet parking demands on transportation infrastructure. Irregular construction and excessive population growth in urban areas required re-planning and site selection of parking places. In this study, an analysis algorithm was developed to determine location-based parking demand by using Geographic Information System (GIS) techniques. After calculating parking demand and supply balance, the location-allocation techniques of network analysis were implemented to determine the best locations of parking, depending on parking demand. These processing tools were tested for an urban area. As a result, an innovative data processing method was developed to determine the best locations of car parking.

Turkey started e-government actions to build Turkey’s National Spatial Data Infrastructure titled as “Turkey National GIS” (TUCBS or TRGIS in English) in 2004. TRGIS actions aim to enable effective use and sharing of geographic data on electronic communication network by developing standards, policies, and technologies. Consecutive actions determined current situation and general vision. However, requirements could not be determined on production, management, and sharing of geographic data. General Directorate of GIS was and to build legal and administrative structure of National GIS. Hereby, national GIS strategy and the legislation framework were determined to manage geographic information. General administrative structure was designed for National GIS committee and working groups. National GIS portal with its metadata standard is being built to share geographic information. As a result of analyzing existing applications, data requirement works, and international standards; data specifications were designed for base geo-data themes. These standards are being tested to use in GIS projects of Turkey. By taking problems and processes into account, this study examines activities for building National GIS and gives milestones supporting National GIS initiatives as an integral part of land management

Posted on by Posted in cbs, English, geo-istatistik, tez

İTÜ Bilişim Enstitüsü Coğrafi Bilgi Teknolojileri Lisansüstü Programı öğrencisi İrem ERKUŞ tarafından Doç. Dr. Arif Çağdaş AYDINOĞLU danışmanlığında hazırlanan “Sosyal Medyada Kullanıcı Profillerinin Belirlenmesinde Konumsal İstatistik Tekniklerin Kullanilmasi” konulu yüksek lisans tezi tamamlanmıştır.

ABSTRACT 

Social media became hot topic after millennium. Beside communication techniques such e-mail and mobile phone, social media platforms have started to be used in various different social and working discipline, to illustrate this, Facebook for social communication, Twitter for short messages, and Flickr for photo sharing, and so on. Most social media platform has possibility to locate any social media activity spatially. Defining any activity with location or position in social media means that distribution of social media users can be analyzed spatially to determine user profiles.

The purpose of this study is to determine user profiles of social media platforms with the examples of online dating site. The data of users are integrated with in GIS environment using spatial statistics techniques.

In methodology part, spatial statistical methods were used to understand the data relationships. Firstly, the distribution of patterns is analyzed spatially to determine data outliers. Then, user profiles are analyzed by age, gender, income, educational level and occupation to examine socio-demographic relationships. Lastly, target areas are determined by using cluster analysis while relations of the data is analyzed by using regression techniques.

The applications consist of four parts. As working principles of GIS, related spatial data was captured, queried, analyzed and visualized in ArcGIS program. Data about ten thousands of users who often use this online dating site was retrieved from the MySQL database by using spatial data query. The distribution and outliers of the data were determining by using Exploratory Spatial Data Analysis (ESDA) tools which are histogram, semivariogram,voronoi map, and QQ plots. Furthermore, the population of Istanbul was examined with spatial statistical analysis based on the data of Adress based Population Registration System and social media site. The results were interpreted and showed in thematic maps, and presented results in a diverse range of visualization options such as reports, statistical graphics and tables. The third part examine the hot-spot analysis to find the clustered area of social media users by using mapping cluster toolset. The final part demonstrate the OLS and GWR regression methods to identify regression model by using spatial relationships tools. In this way, this study contributes to research about social media a new developing discipline. This gives a perspective of user profile in view of education and occupation by using spatial statistical approaches. All in all, this thesis gives an idea about social media and usable statistical techniques.

Türkiye Ulusal CBS Altyapısı Kurulması için Politika ve Standartlar

ÖZET

Türkiye, Ulusal CBS (TUCBS) olarak isimlendirilen Ulusal Konumsal Veri Altyapısı kurulması için e-devlet eylemlerine 2004 yılında başladı. TUCBS eylemleri, geliştirilen standartlar, politikalar ve teknolojiler ile elektronik iletişim ağlarında coğrafi verinin etkin kullanımı ve paylaşımını amaçlamaktadır. Devam eden eylemlerde mevcut durum ve genel vizyon belirlenmiştir. Ancak coğrafi verinin üretimi, yönetimi ve paylaşımında gereksinimler belirlenemedi.

CBS Genel Müdürlüğü, 2011 yılında kurulmuştur. Coğrafi veri standartlarının belirlenmesi ve Ulusal CBS’nin yasal ve idari yapısını oluşturmak için projelere hız verildi. Böylelikle coğrafi bilginin yönetiminde ulusal CBS stratejisi ve yasal çerçeve belirlenmiştir. Ulusal CBS komitesi ve çalışma gruplarının genel idari yapısı tasarlandı. Ulusal CBS portalı, metaveri standardıyla coğrafi bilgiyi paylaşmak için kurulmaktadır. Mevcut verinin analizi, kurumlarda uygulanan veri gereksinim analizi ve uluslararası standartların analizi sonucu; 10 temel coğrafi veri temasını temsil eden veri standartları belirlenmiştir. Bu standartların CBS projelerinde uyumlu kullanımını test edilmektedir.
