Abstract

This study investigates the integration of Geographic Information Systems (GIS) and Unmanned Aerial Vehicle (UAV) technologies in geosciences, focusing on geophysical applications. While GIS enables the management and spatial analysis of various data layers, UAVs allow for the rapid and cost-effective acquisition of high-resolution surface data. The synergy between these technologies enhances the modeling of geophysical processes and improves the effectiveness of risk assessment efforts. Supported by relevant literature, this integrated approach is exemplified through a case study conducted in the Buca-İzmir, Turkey. This application used photogrammetric methods to produce a digital surface model (DSM), followed by slope analyses in a GIS environment to identify potential landslide and ground failure zones. Subsequently, geophysical surveys were conducted to model the subsurface structures associated with these risks. The findings demonstrate that integrating GIS and UAVs provides a fast, precise, and holistic framework for geophysical engineering applications. Furthermore, the study presents a practical example of how these technologies can be effectively utilized in disaster risk reduction and land-use planning.

Özet

Bu çalışma, Coğrafi Bilgi Sistemleri (CBS) ve İnsansız Hava Araçları (İHA) teknolojilerinin yerbilimleri ve özellikle jeofizik uygulamalardaki kullanımını incelemektedir. CBS, mekânsal verilerin yönetilmesini ve analiz edilmesini sağlarken, İHA teknolojisi yüksek çözünürlüklü yüzey verilerinin hızlı ve ekonomik bir biçimde elde edilmesini mümkün kılmaktadır. Bu iki teknolojinin entegrasyonu, yerbilimsel süreçlerin daha doğru modellenmesini ve risk analizi çalışmalarının etkinliğini artırmaktadır. Literatürdeki uygulamalar ışığında değerlendirilen bu bütünleşik yaklaşım, İzmir-Buca’da yürütülen bir örnek çalışma ile somutlaştırılmıştır. Söz konusu çalışmada, fotogrametrik yöntemlerle üretilen sayısal yüzey modeli ve eğim haritaları CBS ortamında analiz edilerek potansiyel heyelan/göçme alanları belirlenmiş, ardından gerçekleştirilen jeofizik ölçümler ile yer altı yapılar modellenmiştir. Sonuçlar, CBS ve İHA teknolojilerinin jeofizik mühendisliğinde hızlı, hassas ve entegre analiz süreçleri sunduğunu ortaya koymaktadır. Ayrıca bu çalışma, doğal afetlerin önlenmesi ve arazi kullanım planlamasında söz konusu teknolojilerin nasıl etkin kullanılabileceğine dair uygulamalı bir örnek sunmaktadır.
