Urbogeosystemic Approach to Agglomeration Study within the Urban Remote Sensing Frameworks

Abstract

The spatial arrangement of human activity within urban areas is normally provided by areal management, and its effective provision is a complicated problem. The current urban development causes a number of problems and urgent challenges, which can be met and resolved exclusively on the basis of innovative scientific and technological advances. The main research objective of this chapter is to represent the authors’ theoretic concept of the urban geographical system combined with the original Urban Remote Sensing approach based on the advanced technique of airborne LiDAR (Light Detection And Ranging) data processing. The authors attempted to prove that the presented concept could contribute to an understanding of the urban agglomeration as an urbanized spatial entity. The chapter explains in what way the urbanistic environment is a quasi-rasterized 3D model of actual city space, and the urbogeosystem (UGS) is a quasi-vector 3D model of the hierarchical formalized aggregate of UGS elementary functional units–buildings, both can efficiently simulate and visualize an urbanized area. Web-based geoinformation software for LiDAR data processing with the objectives of urban studies has been introduced together with its key functionalities. The population estimation use case has been examined in detail within the presented approach frameworks.

The performance of the digital city projects in urban studies of the megalopolises (the case studies of Kharkiv and Dnipro cities)

“…We have proved in the relevant implementations of the urban environment digitalization, that such ontological model would not be merely a theoretical construct, but a practical framework that underpins the development of a Digital City Project [11,13,37].…”

“…1). In other words, these can be any vector objects with a spatial reference and the attributes within a specific extent of the geographical space, what strongly corresponds to the urbogeosystem theory [11,13,19].…”

“…4. The user's scenarios that can be implemented for Kharkiv's DCP in the ELiT web-software [12,13,47]: A -a user's case of energy consumption per building (according to the legend); B -a user's case of population estimation with building geometries -by a number of residents per building (according to the legend); ); C -a user's case of visibility modeling in urban environment ple, this information can significantly enhance the capabilities of geospatial marketing analysis, aid in identifying urban planning issues, assist in optimizing urban services, and support the planning of new districts and infrastructural networks, what is considered in the following sections of this paper.…”

“…We have already attempted to prove in our quite a few previous publications, that the introduced in it the urbogeosystemic research approach implemented within the Urban Remote Sensing (URS) frameworks can hardly be overvalued in a perspective of the contemporary urban studies [11][12][13].…”

“…At its core, UA is a comprehensive framework that conceptualizes cities as dynamic, interconnected systems and recognizes that modern cities are complex, multifaceted entities influenced by a multitude of factors, from environmental conditions to socioeconomic dynamics [11][12][13]. An urbogeosystem sees urban environments as living organisms, where every element, whether natural or artificial, plays a role in shaping this city identity.…”
