Urban Landscape Fragmentation as an Indicator of Urban Expansion Using Sentinel-2 Imageries

Rapid urbanization in some cities has led to the emergence of numerous subsidiary settlements around their primary cities. Due this rapid and growth, there is a great demand for urban land, mostly commercial, industrial, residential uses. Urban green spaces vegetation are at risk due large amount as seen by decline connectivity increased fragmentation, especially land conversion. However, identification spatial momentary variability clustering fragmentation patterns settings not made full use local indicators distribution measurements, such Baqubah, city Iraq. Since it essential measure degree evaluate expansion trajectories consistently, study proposes new approach assessing anticipated direction extension, using indicator built-up areas. Sentinel-2 data was used map fragmented centres future extent single time point. The proposed method employs indices capture initial cover main extracted classes, landscape performance, surface density analysis were accomplished ArcGIS. results indicate that entire area Baqubah high 75%, about 23% open space within city. Two predicted also revealed: one may follow external road direction, while other multi-directional, commencing from edges area. concludes useful comprehending well anticipating its path. This integrated remote sensing GIS can sufficiently effectively determine priority regions successful planning management. In addition, our study's findings highlight potential suggested strategy spatially explicit determining patterns. Doi: 10.28991/CEJ-2022-08-09-04 Full Text: PDF
