Sokak Seviyesindeki Yeşil Görünürlük İndeksinin(GVI) GSV ve YSV ile Değişiminin İncelenmesi

Öz

Sokak seviyesindeki yeşil alanlar, kentsel peyzajların görsel kalitesinde kritik bir rol oynamaktadır. Bu değişen canlı peyzaj elemanlarına ilişkin bilgiler, web tabanlı araçların sokak seviyesindeki görüntülerinden elde edilebilmekte ve görsel etki kalitesi açısından değerlendirilebilmektedir. Bu değerlendirme, kentsel peyzaj planlama ve yönetiminde sokak seviyesi yeşil alan bilgilerine dahil edilebilmektedir. Bu çalışmada, kentsel yeşili değerlendirmek için Google Sokak Görünümü (GSV) ve Yandex Sokak Görünümü'nün (YSV) sokak seviyesi görüntüleri kullanılmıştır. GSV ve YSV'nin kentsel yeşilin sokak seviyesi profil görünümlerini sağlayabilen araçlar olması avantajlıdır. Bu avantaj kullanılarak, çalışmada İstanbul'un Kadıköy ilçesinden seçilen sokaklar için Yeşil Görünüm Endeksi (GVI) hesaplanmış ve 2011-2020/2023 yılları arasında sokak dokusundaki yeşilin değişimi değerlendirilmiştir. Kentsel dönüşümden etkilenen sokak dokusundaki yeşil alanın azaldığı tespit edilmiştir ve sokak düzeyindeki yeşilliğin web tabanlı araçlar aracılığıyla ölçülüp değerlendirilebileceği görülmüştür.

Examining the Change of Green View Index (GVI) at Street Eye-Level with GSV and YSV

Abstract

Street-level green areas play a critical role in the visual quality of urban landscapes. Information on these changing live landscape elements can be obtained from street-level images of web-based tools and evaluated in terms of visual impact quality. This assessment can include information on street-level green areas in urban landscape planning and management. This study used street-level images of Google Street View and Yandex Street View to evaluate urban green. Advantageously, GSV and YSV are tools that can provide street-level profile views of urban green. Using this advantage, the Green View Index (GVI) was calculated for selected streets in Kadıköy district of Istanbul, and the change in greenness in the street texture between 2011-2020/2023 was evaluated. It was determined that the green area in the street texture affected by urban transformation decreased, and it was seen that the greenness at the street level can be measured and evaluated through web-based tools.
