Description
Summary:Dissertation submitted in partial fulfilment of the requirements for the degree of Master of Science in Geospatial TechnologiesThe quality of life in a particular city might be affected by the rate of commit- ting crimes in which citizens always like to live in a safe neighborhood. One type of crime that can have a negative impact on the society and also victim’s personal life is sex-based crimes. In this thesis, we aim at studying the spatial behavior of a sex-based crime dataset from Chicago (US). This dataset contains two types of sex-based crimes: 1) sexual assault, 2) sex offense. The dataset contains 11627 assaults and 9275 offenses in the period of [2007-2017]. Results show that Sexual Assault and Sex Offenses are distributed inhomogeneously on space, creating clusters in some zones of Chicago. Also, we noticed that there space where we found one event of Sexual Assault the probability of finding near one event of Sex Offense is really high. We also did a basic temporal analysis where we found that sex-based crimes have a higher rate during summer months and based on days of the week, sexual assault tend to be committed more during weekends.La calidad de vida en una ciudad puede verse afectada por la tasa de delitos ya que lo ciudadanos prefieren vivir en barrios donde sientan cierta seguridad. Uno de los tipos delictivos que puede ser ms gravaso, no solo para la sociedad, sino para la vida personal de la vctima, son los delitos sexuales. El propsito de esta tesis es estudiar el comportamiento espacial de los deli- tos sexuales cometidos en la ciudad de Chicago. La base de datos contiene dos tipos delictivos: 1) Asalto sexual, 2) Ofensa sexual, existiendo un total de 11627 delitos para el asalto sexual y 9275 delitos de ofensa sexual recogidos durante un periodo de 10 aos; 2007-2017.
