The understanding of spatial and geometrical patterns in urbanization is crucial in tackling its associated problems. As urbanization progresses through various stages of development, it reflects different forms, patterns, and interactions based on physical and functional aspects. Spatial metrics, a well-regarded technique for quantifying urban characteristics, is one of several methods developed to achieve this. The current study was conducted in Tiruchirappalli and six other urban centres located within a 40-kilometre radius; which helps to comprehend the comparative growth and spatial patterns in relation to Tiruchirappalli urban centre. The urban centres were divided into eight zones based on direction for more precise quantification. The study employed Landsat 5 and 8 satellite images to classify land use/cover for the periods 1996, 2008, and 2020, which were then used to assess urban spatial growth and quantify spatial and geometrical patterns. Fragstat, a comprehensive application with several metrics, was used to analyse spatial metrics, including patch, class, and landscape levels, which focus on spatial configurations such as area and edge, aggregation, diversity, and shape. The study generated significant data about spatial and geometric properties, patterns, and obstructions of growth. The area and edge metrics and aggregation metrics indicated that Manachanallur, Manapparai, Musiri, Thiruverumbur, and Thuraiyur had the most unpredictable, random growth with highly protrusive urban growth in few zones across the study period. Diversity metrics demonstrated that Tiruchirappalli had the most abundant urban patches, with few patches from other classes. Shape metrics revealed significant improvements from 2008–2020 across all urban centres, whereas from 1996–2008, urban patches were more irregular in shape. The current study is a significant contribution to the urban research in understanding the relative spatial and geometric patterns of urbanization. The knowledge generated could aid in sustainable urban development planning and focus.

Understanding spatial and geometrical patterns of urbanization is crucial in tackling associated problems. As urbanization progresses through various stages of development, it reflects different forms, patterns, and interactions based on its physical and functional aspects. Spatial metrics is a well-acclaimed technique for quantifying urban morphological characteristics. The current study was conducted for Tiruchirappalli and six tier-urban centers located within a 40-kilometers radius to comprehend the comparative growth and spatial patterns. The urban centers are divided into eight zones based on direction for more precise quantification. The study employed Landsat 5 and 8 satellite images to classify land use/cover for the periods 1996, 2008, and 2020. FRAGSTAT is the software application used to analyze spatial metrics, at patch, class, and landscape levels. The study generated a significant amount of data about spatial and geometric patterns of growth. Area, edge, and aggregation metrics indicated that zones in Manachanallur, Manapparai, Musiri, Thiruverumbur, and Thuraiyur had protrusive urban growth during the study period. Transport networks have been the instrumental factor for such growth. Diversity metrics revealed Tiruchirappalli and Thiruverumbur have abundant patches of various classes in many of their zones since they retain patches like open, vegetation, and water bodies extensively. Shape metrics across all urban centers during the period 1996-2008 were more irregular in shape; it has become significantly smooth during 2008-2020 due to infill developments on the fringe areas. The period 1996-2008 recorded a huge transition of open areas into built-ups, attributing to infill development, especially inside the urban centers; similarly, during the period 2008-2020, edge expansion has been recorded widely across the urban centers. The current study is a significant contribution to urban research in understanding relative spatial and geometric patterns of urbanization.
