Bozkırlar, ekolojik açıdan büyük öneme sahiptir ve doğal kaynak yönetimi veya biyoçeşitlilik koruma gibi çalışmalar için bozkır alanlarının doğru olarak bilinmesine ihtiyaç vardır. Ancak, genel amaçlı arazi örtüsü sınıflandırmalarında bozkır sınıflandırma doğruluğu genellikle düşüktür. Bu çalışmada uzaktan algılama yöntemi ile bozkırların sınıflandırılmasına yönelik bir algoritma önerilmiştir. Bitki fenolojisinden azami seviyede faydalanmak için çok-zamanlı multispektral Sentinel-2A uydu görüntüleri kullanılmıştır. Eğitimli ve eğitimsiz sınıflandırma yöntemlerinin melez olarak kullanıldığı yöntem ile test sahasında %89 doğruluğa ulaşılmıştır.

Identification and mapping of submerged plants in a shallow lake using quickbird satellite data
Dogan, Ozge Karabulut; Akyürek, Sevda Zuhal; Beklioğlu, Meryem (2009-05-01)
Turkey is a country rich in lakes and wetlands - monitoring of all these will require advances in technology such as remote sensing. In this study. the aquatic plants of the large and shallow Lake Mogan, located in Central Anatolia were identified and mapped using high spatial resolution Quickbird imagery. As Lake Mogan is an important bird area the assessment of submerged plant species is of great value for ecosystem conservation and management. Quickbird multispectral image acquired on August 6, 2005 was ...
Using functional diversity components to describe phytoplankton community assembly processes in Turkish shallow lakes
Acar, Vildan; Beklioğlu, Meryem; Department of Biology (2022-4-22)
The recent increase in biodiversity loss due to various anthropogenic effects makes it crucial to understand the relationship between biodiversity and ecosystem functioning for the conservation and preservation of ecosystems. Clasically, biodiversity and ecosystem functioning studies use species diversity as a measure of biodiversity, but functional diversity has been shown in some cases to better explain and predict ecosystem-level processes. In this study, we investigated the role of dispersal, environmen...
Wetland spectral unmixing using multispectral satellite images
Ozer, Erdem; Leloğlu, Uğur Murat (2022-07-01)
Wetlands are of great importance to the diversity of biota and ecology, thereby to humans. Monitoring such valuable areas is essential for sustainable development. When the sizes, geographic distribution, and total coverage of wetlands across the earth are taken into account, remote sensing shines out as the most economically and technically feasible method to realise the monitoring task. Concerning the utilisation of medium resolution satellite images as the input, the pixel-level approach falls short of u...
Assessment of Environmental Flows under Human Intervention and Climate Change Conditions in a Mediterranean Watershed
Yılmaz, Mustafa Tuğrul; Alp, Emre; Sarıcan, Yeliz; Afsar, Mehdi; Bulut, Burak; Ersoy, Erhan Nuri; Karasu, İpek Gül; Önen, Alper (null; 2017-12-15)
Allocation of the river flow for ecosystems is very critical for sustainable management of ecosystems containing aquatic habitats in need of more water than other environments. Availability and allocation of water over such locations becomes more stressed as a result of the influence of human interventions (e.g., increased water use for irrigation) and the expected change in climate. This study investigates the current and future (until 2100) low-flow requirements over 10 subcatchments in a Mediterranean Wa...
Mediterranean shrub classification using multitemporal multi-spectral satellite images
Listiani, Indira Aprilia; Leloğlu, Uğur Murat; Zeydanlı, Uğur Siyami; Department of Geodetic and Geographical Information Technologies (2021-2-12)
Shrublands, which have a crucial role in retaining the ecological balance, constitute an important part of the Mediterranean ecosystems. However, their composition, distribution and dynamics are not well understood. It is necessary to know the distribution of the alliances at regional scale in order to construct models that explain their dynamics. Such models will help researchers to evaluate their role in ecosystems and predict their responses to climate change. Necessary alliance distribution maps can onl...
