  1. 1. Fractal or Scaling Analysis of Natural Cities Extracted from Open Geographic Data Sources

    University essay from Högskolan i Gävle/Avdelningen för Industriell utveckling, IT och Samhällsbyggnad

    Author : KUAN-YU HUANG; [2015]
    Keywords : Open geographic data; box counting fractal dimension; head tail breaks classification; lacunarity; natural cities;

    Abstract : A city consists of many elements such as humans, buildings, and roads. The complexity of cities is difficult to measure using Euclidean geometry. In this study, we use fractal geometry (scaling analysis) to measure the complexity of urban areas. We observe urban development from different perspectives using the bottom-up approach. READ MORE

  3. 2. Examining the New Kind of Beauty Using the Human Being as a Measuring Instrument

    University essay from Högskolan i Gävle/Avdelningen för Industriell utveckling, IT och Samhällsbyggnad

    Author : Jou-Hsuan Wu; [2015]
    Keywords : Cartography; scaling; head tail breaks; the theory of centers; fractals; and the mirror-of-the-self test;

    Abstract : A map combines scientific facts with aesthetic perceptions. This study argues that scaling is universal in mapping reality and evoking a sense of beauty. Scaling laws are used to reveal the underlying structures and dynamics of spatial features. Complex systems, such as living cities involve various interacting entities at all scales. READ MORE

  4. 3. A Case Study on the Extraction of the Natural Cities from Nightlight Image of the United States of America

    University essay from Avdelningen för Industriell utveckling, IT och Samhällsbyggnad

    Author : QINGLING LIU; [2013]
    Keywords : cities boundaries; DMSP OLS; head tail breaks classification; nighttime lights; power law; urban areas;

    Abstract : The boundaries of the cities are not immutable, they can be changed. With the development of the economies and societies, the population and pollution of cities are increasing. Some urban areas are expanding with more population or other dynamics of urbanization, while other urban areas are reducing with the changing of the dynamics. READ MORE

  5. 4. A Comparison Study on Natural and Head/tail Breaks Involving Digital Elevation Models

    University essay from Avdelningen för Industriell utveckling, IT och Samhällsbyggnad

    Author : Yue Lin; [2013]
    Keywords : Head tail breaks; natural breaks; heavy-tailed distribution; scaling property; data classification; digital elevation models;

    Abstract : The most widely used classification method for statistical mapping is Jenks’s natural breaks. However, it has been found that natural breaks is not good at classifying data which have scaling property. Scaling property is ubiquitous in many societal and natural phenomena. It can be explained as there are far more smaller things than larger ones. READ MORE
