This thesis presents methods, techniques and tools for developing three-dimensional representations of tactical intelligence assessments. Techniques from GIScience are combined with crime mapping methods. The range of methods applied in this study provides spatio-temporal GIS analysis as well as 3D geovisualisation and GIS programming. The work presents methods to enhance digital three-dimensional city models with application specific thematic information. This information facilitates further geovisual analysis, for instance, estimations of urban risks exposure. Specific methods and workflows are developed to facilitate the integration of spatio-temporal crime scene analysis results into 3D tactical intelligence assessments. Analysis comprises hotspot identification with kernel-density-estimation techniques (KDE), LISA-based verification of KDE hotspots as well as geospatial hotspot area characterisation and repeat victimisation analysis. To visualise the findings of such extensive geospatial analysis, three-dimensional geovirtual environments are created. Workflows are developed to integrate analysis results into these environments and to combine them with additional geospatial data. The resulting 3D visualisations allow for an efficient communication of complex findings of geospatial crime scene analysis. / Diese Arbeit präsentiert Methoden, Techniken und Werkzeuge für die Entwicklung dreidi-mensionaler Lagebilder. Zu diesem Zweck werden Verfahren der Geoinformatik mit solchen der raumbezogenen Straftatenanalyse kombiniert. Das Spektrum der angewandten Methoden und Techniken umfasst raumzeitliche GIS-Analysen ebenso wie 3D Geovisualisierungen und GIS-Anwendungsprogrammierung. Um komplexe geovisuelle Analysen auf Basis virtueller 3D-Stadtmodelle zu ermöglichen, werden Datenbanken digitaler Stadtmodelle um anwendungsspezifische Fachinformationen ergänzt. Dies ermöglicht weiterführende Analysen, zum Beispiel zur räumlichen Verteilung urbaner Risiken. Weiterhin präsentiert die Arbeit Methoden und Verfahren zur Integration der Ergebnisse komplexer raumzeitlicher Straftatenanalysen in dreidimensionale Lagebilder. Die durchgeführten Analysen umfassen die Identifikation von Brennpunkten spezifischer Delikte mittels Techniken der Kerndichteschätzung, die Verifikation dieser Hotspots durch LISA-Statistiken, GIS-basierte räumliche Charakterisierungen von Brennpunkten sowie Analysen zur wiederholten Viktimisierung. Zur Visualisierung der Ergebnisse komplexer raumzeitlicher Analysen werden dreidimensionale geovirtuelle Umgebungen erzeugt. Um weitere raumbezogene Daten ergänzt, werden sämtliche Analyseergebnisse in diese Umgebungen integriert. Die resultierenden 3D-Visualisierungen erlauben eine effiziente Kommunikation der Ergebnisse komplexer raumbezogener Straftatenanalysen.

The population of Sweden is ageing as in almost every European country. Improved medical progresses and treatment options lead to a decreasing mortality at older ages, increasing life expectance and an advanced health of the elderly. Due to these improvements and the so called ‘baby- boomers’, a great number of persons born in the 1940s that will reach retirement age the coming years, their total number will increase strongly in the near future all over Sweden. To enable these elderly to live a normal, active and independent life as long as possible activities, services and special housing with improved accessibility and meeting places for elderly has to be provided. Thus, for local authorities it is essential to know the actual and favoured living conditions as well as environments of elderly. This study aims therefore to investigate the characteristic of preferred residential neighbourhoods of the elderly in the city of Norrköping. The demographic, social and crime situation was examined for the districts of the city using several methods from both Statistics and GIS. Statistical methods included classifications, indexes or indicators and bivariate correlations. A model was developed to combine demographic and social data to characterise districts. GIS was to a major extent used as a visualisation tool. Choropleth mapping and Kernel density estimations were used to illustrate distribution of elderly and crime. Preliminary global statistical tests were used to verify clustering in the crime data set. An accessibility analysis was conducted with the help of the network analyst tool. Results indicate that districts experiencing the highest total numbers and proportion of elderly are very distributed throughout the city of Norrköping. They are, with some exceptions, characterised by lower social status. Four districts of the city show considerable evidences of demographic ageing, experiencing a population pyramid formed like an urn. Beside districts where elderly constitute a bigger proportion of the population, they tend to live in districts characterised by a relatively high proportion of young adults aged between 20 and 29. Crime analyses have shown crime clusters in different parts of the city. A high proportion of elderly faces a high crime level in the districts Gamla staden, Nordantill and Hageby. However, it has been proved that only some hot spots of crime within these areas contribute to the high crime level. Districts such as Skarphagen, Såpkullen, Smedby and Linö, all (except Såpkullen) situated on the outskirts of the city, hold high or middle elderly and a low crime level. Accessibility analyses have shown that elderly aged over 80 do not live significant closer to health centres and the public transport stops compared to the age groups 20 – 65 and inhabitants aged between 65 and 79.

This dissertation addresses the validation of the hypothesis there is a general sense that violence and security perception influence the use of sustainable travel modes. The research characterizes the issue of security perception among University of São Paulo (Brazil) users and identifies the way the sense of security and violence occurrences are related to the travel mode choice. An online survey on security perception and the way its participants access the campus was conducted. The target relationships were explored by Decision Tree (DT) algorithms. An initial exploratory analysis revealed occurrences of violence and reports of insecurity perception were strongly correlated on streets around the campus. The time analysis of violence distribution presented the incidents concentrated at night and during the week. The study also showed that security perception variation according to gender and travel mode choice is less sensitive to security perception than to the occurrence of violence, or type of affiliation to the university. Finally, DT algorithms explored the relation of spatially treated variables (i.e. route length to the university, density of violence occurrences and insecurity reports on the route) to mode choice. The results also showed that distance to the campus was relevant to the mode choice only in routes not strongly considered unsafe. In routes of higher insecurity perception, the share of nonmotorized modes was more expressive and the largest participation of sustainable modes was on routes with high incidence of violence. Since it is counterintuitive to assume numerous walking trips are a consequence of violence, the opposite was considered as a possible explanation to those results. The present study reinforces the need for increased surveillance in regions with high participation of non-motorized modes, for preventing users from shifting to motorized modes. / Esta dissertação busca comprovar a hipótese de que a violência e a percepção de segurança influenciam o uso de modos de transporte sustentáveis. A pesquisa caracteriza a questão da percepção de segurança entre os usuários da Universidade de São Paulo (Brasil), em São Carlos, e identifica como o sentimento de segurança pessoal e a violência estão relacionados com a escolha do modo de viagem. Foi realizada uma pesquisa on-line sobre a percepção de segurança dos usuários da universidade e a forma como eles acessam o campus. As interações foram exploradas por algoritmos de Árvore de Decisão (AD). Uma análise exploratória inicial mostrou que ocorrências de violência e relatos de insegurança estavam fortemente correlacionados nos trechos de via ao redor do campus. A análise temporal da distribuição da violência apresentou os incidentes concentrados à noite e durante os dias de semana. Além disso, a pesquisa mostrou que a percepção de segurança variou de acordo com o gênero e a escolha modal é menos sensível à percepção de segurança do que a ocorrência de violência, ou vinculação com a universidade. Por fim, os algoritmos de AD foram executados para explorar a relação das variáveis tratadas espacialmente (ou seja, o comprimento da rota até o campus, além da densidade de ocorrências e relatos de insegurança na rota) com a escolha modal. O último resultado obtido na análise foi que a distância até a universidade era relevante para a escolha modal apenas em rotas onde não há numerosos relatos de insegurança. A participação dos modos não motorizados foi mais expressiva nas rotas com maior percepção de insegurança, e em rotas com alta incidência de violência. Como não é razoável supor que mais viagens a pé são uma consequência dos roubos e sim o oposto, o estudo reforça a importância de aumentar a segurança nas regiões de alta incidência de viagens não motorizadas, de forma a não incentivar a migração destes usuários para modos motorizados.

The dissertation discusses topics in environmental criminology, which is concerned with crime in relation to the environment where it occurs. The environmental approach is based upon a premise that occurrence of crime in space is neither random nor uniform. On the contrary, various types and forms of criminal activity tend to concentrate in certain places during certain times. Environmental characteristics play an important role in behaviour of individuals, hence it is possible to analyse them as one of the most important determinants of criminal behaviour. The aim of the thesis is to comprehensively introduce to the Czech and Slovak legal and criminological scholarship historical background, development and the main contemporary theoretical approaches in environmental criminology, as well as their implications and utilization in crime analysis and crime prevention. The theoretical part discusses in detail rational choice perspective, routine activity approach and crime pattern theory as an environmental meta-theory. The analytical part introduces the basics of the methods of crime mapping and geographical profiling. It also demonstrates how statistical and mapping techniques can be utilized in practice, using a set of police data concerning thefts from motor vehicles in Prague during the first...

Η παρούσα έρευνα εντάσσεται στο πλαίσιο εκπόνησης διδακτορικής διατριβής στο Εργαστήριο του Τμήματος Αρχιτεκτόνων Μηχανικών του Πανεπιστημίου Πατρών. Η χαρτογράφηση της εγκληματικότητας (Crime Mapping) είναι η διαδικασία χρήσης της τεχνολογίας των Γεωγραφικών Συστημάτων Πληροφοριών και της εφαρμογής μεθόδων και τεχνικών της Χωρικής Ανάλυσης και της Χαρτογραφίας για την μελέτη και ανάλυση εγκληματικών συμβάντων. Ένα μεγάλο σύνολο ανθρωπίνων δραστηριοτήτων αναπτύσσεται, παρατηρείται και καταγράφεται στους αστικούς χώρους. Η επίδραση που ασκεί ο χώρος στην ανθρώπινη συμπεριφορά αλλά και η επίδραση της ανθρώπινης συμπεριφοράς που ασκείται πάνω στον χώρο είναι μια σχέση αμφίδρομη και αποτελεί σημαντικό στοιχείο για το σχεδιασμό. Συνεπώς, η δομή αυτή καθ’ αυτή των πόλεων, οι ήδη διαμορφωμένοι δημόσιοι αστικοί χώροι και οι κοινωνικό-οικονομικές αλλαγές που συντελούνται, συνιστούν μια πρόκληση για τους σύγχρονους σχεδιαστές του χώρου αυτού. Η έρευνα αφορά τη μελέτη της χωρικής κατανομής εγκλημάτων ιδιοκτησίας (απόπειρες, κλοπές, διαρρήξεις, ληστείες) στον αστικό ιστό της πόλης σε σχέση με χωρικά χαρακτηριστικά και κυρίως με πολεοδομικές παραμέτρους, ενώ παράλληλα εστιάζει με τρόπο ώστε να είναι δυνατή η εφαρμογή και ενσωμάτωση πορισμάτων της εγκληματολογίας στην διαδικασία του πολεοδομικού σχεδιασμού και γενικότερα του σχεδιασμού του χώρου. Ολοκληρώνεται, με συστηματική μελέτη περίπτωσης, μέσω αναλυτικής στατιστικής ανάλυσης και ανάλυσης γεωστατιστικής σχετικών δεδομένων που αφορούν το Σχέδιο Πόλεως Πατρών και τη δημιουργία γεωσυνόλων και θεματικών χαρτών που απεικονίζουν τη χωρική κατανομή του φαινομένου. Για την ανάλυση των χαρακτηριστικών της μελέτης περίπτωσης χρησιμοποιούνται χωρικές βάσεις δεδομένων με στοιχεία που η Γενική Αστυνομική Διεύθυνση Περιφέρειας Δυτικής Ελλάδος διέθεσε για την εκπόνηση της εργασίας: 4.770 απογραφικά δελτία εγκληματικών συμβάντων (εγκλήματα ιδιοκτησίας) που αφορούν το σύνολο τεσσάρων ετών από το 2007 έως και το 2010. Η εκπόνηση της έρευνας χρηματοδοτήθηκε από το Επιχειρησιακό Πρόγραμμα Εκπαίδευση και Δια Βίου Μάθηση, Ηράκλειτος ΙΙ, Υπουργείο Παιδείας και Θρησκευμάτων, ΕΣΠΑ 2007 – 2013, Ευρωπαϊκό Κοινωνικό Ταμείο. / This thesis has been elaborated in the Laboratory of Urban and Regional Planning, Department of Architecture, University of Patras. Crime Mapping is the process of using GIS technology and the implementation of Spatial Analysis and Mapping methods for studying and analysis of criminal incidents. In recent years, the rapid evolution of GIS technology and the availability of digital spatial data have strengthened the significant role of spatial analysis and GIS in crime analysis. A great deal of human activity is developed, observed and recorded in urban areas. The human impact is implemented on the urban areas as well as the urban areas have an impact on human behavior, setting a correlation that is an important design/planning characteristic. Consequently, the structure of modern cities, the existing urban public spaces along with the socioeconomic changes that happen constitute a challenge for contemporary designers and planners. The research is based on the study of spatial criminal distribution of property crimes (attempts, thefts, burglaries, robberies) in the urban web of a city, in terms of spatial characteristics and urban planning parameters while it focuses on criminology findings so as they can be incorporated and applied in urban planning in order to design and identify strategic orientations and create safer urban areas. It concludes with a systematic case study through an analytical statistical and geostatistical analysis of relevant data concerning the Master Plan of city of Patras and the development of geosets and thematic maps depicting the spatial distribution of the phenomenon. For that purpose, the Central Police Department of Patras offered to the university Laboratory all census forms of criminal acts and events (property crimes): 4.770 reports that took place at the city of Patras (Greece) during the years 2007 – 2010. This research has been co-financed by the European Union (European Social Fund – ESF) and Greek national funds through the Operational Program “Education and Lifelong Learning” of the National Strategic Reference Framework (NSRF) - Research Funding Program: Heracleitus II.

Indiana University-Purdue University Indianapolis (IUPUI) / Law enforcement agencies across the U.S. use maps of crime to inform their practice and make efforts to reduce crime. Hotspot maps using historic crime data can show practitioners concentrated areas of criminal offenses and the types of offenses that have occurred; however, not all of these hotspot crime mapping techniques produce the same results. This study compares three hotspot crime mapping techniques and four crime types using the Predictive Accuracy Index (PAI) to measure the predictive accuracy of these mapping techniques in Marion County, Indiana. Results show that the grid hotspot mapping technique and crimes of robbery are most predictive. Understanding the most effective crime mapping technique will allow law enforcement to better predict and therefore prevent crimes.

The study investigated the application of the crime threat analysis process at station level within the Nelson Mandela Metro City area with the objective of determining inhibiting factors (constraints) and best practices. Qualitative research methodology was applied and interviews were conducted with crime analysts and specialised investigators/intelligence analysts. The research design can be best described as descriptive and explorative in nature. The crime threat analysis process embroils the application of various crime analysis techniques and the outcomes thereof intends to have a dual purpose of generating operational crime management information in assisting crime prevention initiatives and crime detection efforts, mainly focussing on the criminal activities of group offenders (organised crime related), repeat offenders and serial offenders. During the study it became evident that crime analysts understand and thus apply the crime threat analysis process indifferently, which impeded on the relevancy and the utilisation thereof as an effective crime management tool. / Criminology / M.Tech.
