What is the significance of digital cartography in urban development?5 answersDigital cartography plays a crucial role in urban development by providing tools for spatial analysis, urban planning, and the identification of areas susceptible to disasters. It enables the creation of detailed maps that can support decision-making processes in managing urban areas prone to floods, erosion, and other hazards. The evolution of traditional cartography into numerical cartography, including the development of digital twins, allows for a virtual representation of physical and potential urban resources, aiding in complex urban planning and simulations. Additionally, digital cartography facilitates the inclusion of intangible data and promotes bottom-up practices for urban territory management, enhancing the understanding of urban spaces and fostering strategies for urban regeneration. Furthermore, the association of digital cartography with urban morphology and historical analysis helps decode the complexities of contemporary cities, recognizing their historicity and evolution over time.
What factors contribute to the geomorphological determinants of urbanization?5 answersThe geomorphological determinants of urbanization are influenced by various factors. Settlement development impacts geomorphic evolution significantly, with positive aspects like artificial mounds and water surfaces, and negative effects such as flood-control dykes and large-scale road-cuts. Historical urbanized areas showcase how geomorphological factors condition urbanization, focusing on shoreline evolution, streambeds, and river mouths migration, crucial for city development and harbors. Urban morphology, shaped by socio-economic and cultural processes, includes natural and manmade determinants, with quantifiable measures aiding in urban living quality enhancement. Remote sensing and GIS data help analyze urban expansion patterns, with a spatial-temporal morphological model identifying urban sprawl patterns and driving factors, emphasizing an integrated approach for urban morphology modeling. Urbanization processes in Brazil altered geomorphological features, emphasizing the strong anthropogenic influences on natural dynamics and environmental changes.
What are the methods for predicting urban sprawl?4 answersMethods for predicting urban sprawl include the use of artificial neural networks (ANN) and cellular automata (CA). Another frequently used model is the Cellular Automata-Markov Chain (CA-Markov). Additionally, a hybrid method combining ANN and CA has been employed. Other techniques include random forest (RF), linear regression, K-nearest neighbor, and AdaBoost. These methods utilize various factors such as socio-economic and geographic factors, as well as biophysical factors, to predict urban growth and land use/land cover changes. Validation metrics such as correctness, completeness, and quality indices are used to assess the accuracy and reliability of the predictions. These prediction models and techniques can assist city managers, environmental resources managers, and researchers in making informed decisions for sustainable development and urban planning.
How can GIS be used to improve urban design?4 answersGIS can be used to improve urban design by providing a comprehensive assessment of the location of buildings and structures, taking into account underground utilities and the context of the urban environment. It can also be used to design green urban garden landscapes by considering index evaluation of urban landscaping and its influencing factors, and by introducing rainwater landscape interventions to improve aesthetics and artistry. GIS technology has advantages in the planning and design of urban landscapes, such as scientific, efficient, and intuitive advantages, and can be used to analyze and evaluate urban areas. Additionally, GIS can be used in urban planning information management systems to improve information collection, sharing, and decision-making processes, and to provide a management information operation carrier for urban planning managers.
What isTHE RELATIONSHIP BETWEEN urban morphology and UDI?2 answersUrban morphology has a significant relationship with urban heat island (UHI) intensity. Studies have shown that various urban morphological indicators, such as building morphology, ecological infrastructure, and human activities, are correlated with UHI intensity. The presence of impervious surfaces, high building density, and low sky view factor tend to aggravate UHI, while green areas, open sky, and shade can help mitigate UHI. The relationship between urban morphology and UHI intensity is complex and varies at different scales. Building coverage ratio, building volume density, and frontal area index have been identified as important factors affecting land surface temperature (LST). Additionally, the availability of urban spatial data and advancements in machine learning techniques have opened up new possibilities for studying urban form on a global scale. The integration of different types of data, such as multilayer graphs, can provide multidimensional descriptions of urban form and enable space-time assessments.
What are the main features of urban morphology?5 answersUrban morphology, as described in the abstracts, refers to the physical form and structure of cities. It encompasses the arrangement and characteristics of buildings, streets, open spaces, and other elements that make up the urban environment. The physical morphology of a city is influenced by various factors such as historical, social, cultural, economic, political, demographic, and natural conditions. It reflects the society that created it and evolves over time due to different processes and agents. Urban morphology can be analyzed and classified based on patterns, alignments, densities, and building types. It can also provide insights for the design of new urban forms and the transformation or conservation of existing forms. Additionally, there is a correlation between the physical morphology of a city and its socio-economic characteristics, such as income and property value.
