Decentralized solar PhotoVoltaic (PV) is one of the most promising energy sources for cities and individuals pursuing energy self-sufficiency. Especially, the already available rooftop surfaces are a major contributor to push for rooftop mounted PV systems. However, accurate PV potential estimation of individual buildings is still a challenging tas...

The Akçakale cave is a significant natural and cultural heritage site in the Black Sea region of eastern Turkey. The complex geometry and difficult-to-access areas of the cave have made the use of traditional mapping methods challenging. To overcome these limitations, this study utilized TLS and UAV technology to produce highly accurate 2D and 3D d...

Istanbul is the most populous city in Turkey. The population, which was approximately 5.5 million in 1985, has reached 15.5 million in 2020. Population growth is the most important factor behind human activities that put pressure on the environment. An increasing population means depletion of limited resources, increasing environmental problems, an...

As one of the largest hypersaline lakes, Lake Tuz, located in the middle of Turkey, is a key waterbird habitat and is classified as a Special Environmental Protection Area in the country. It is a dynamic lake, highly affected by evaporation due to its wide expanse and shallowness (water depth <40 cm), in addition to being externally exploited by sa...

Irregular urbanization causes problems such as decrease in fertile agricultural areas, irregular industrialization and urbanization. To provide a healthier life opportunity for future generations without disturbing nature, it is essential to determine the temporal changes in land use and to make land management plans accordingly. In this study, lan...

Today, industrialization and urbanization in large cities cause an increase in the surfaces covered with man-made objects such as concrete and asphalt. The expansion of urban areas and increase in the using materials with high heat storage properties, directly affect the Land Surface Temperature (LST), which shows an increase in the sensible temper...

Tuz Lake and its surrounding lakes (Tersakan Lake, Duden Lake, Bolluk Lake, Esmekaya Lake, Kopek Lake, Akgol) are placed in the Central Anatolia region. These lakes maintain the ecosystem's integrity and make a good habitat for numerous bird species, especially flamingos. The Duden Lake is located within the boundaries of the Tuz Lake Special Envir...

Advances in remote sensing technology enable monitoring and detection of these vulnerable water bodies that bear numerous functions and ecological services beyond their intended use. As such, valuable data and information may be provided for long and short‐term analyses and stored in a database for future projections. This paper initially grouped 1...

Remote sensing data provides great opportunities to be utilized in various steps of watershed management like characterization of watersheds that bear dynamic structure with large land, monitoring the variations within the basin, and conducting various scenario analyses. The high resolution capacity of today’s satellite images enables the productio...

Numerous natural lentic systems of the world are under the threat of drying due to either natural or anthropogenic activities. Natural circumstances are basically due to climate change effects remarkably sensed within the past decades. However, human-induced activities in some cases dominate over natural events due to demand of water particularly f...

Günümüzde büyük kentlerdeki sanayileşme ve kentleşme beton ve asfaltla kaplanmış yüzeylerin artmasına neden olmaktadır. Kent alanlarının genişlemesi ile birlikte yüksek ısı depolama özelliklerine sahip malzemelerin kullanımının artması bölgenin hissedilebilir sıcaklığındaki artışı gösteren Arazi Yüzey Sıcaklığı (AYS) değerini doğrudan etkilemektedi...

ZET Ülkemizde özellikle Doğu Karadeniz bölgesinde yetişmekte olan çay bitkisi bölgede yaşayan halkın geçim kaynağının büyük bir kısmını oluşturmaktadır. Ancak Doğu Karadeniz Bölgesinde yağışlara bağlı olarak meydana gelen heyelanlar çay alanlarının sürekli hasara uğramasına neden olmaktadır. Bu doğrultuda çay alanlarının zamansal izlenmesi ve takib...

In case of fire, determination of burned trees and fire direction is very important. Until now, satellite images and aerial photographs have been widely used in forest fire studies. However, these data can be ineffective in terms of temporal and spatial resolution. In recent years, due to high resolution of provided images, use of Unmanned Aerial V...

This study determined the temporal changes of the lentic water surfaces at every 5 years interval during 1987-2017 through utilizing RS technology in the highly water scarce Konya Closed Basin (KCB) of Turkey with the aim of supplying data for the decision-makers responsible of water management. Spatiotemporal changes of lentic water bodies in the...

Remote sensing that is a low cost data source capable of making temporal observations has more advantages than the traditional methods to obtain land-use/cover change maps. In this study, temporal land-use/cover change of surface water bodies in Konya Closed Basin was evaluated via Landsat satellite images for the past 30 years. The basin, located...

Apart from their ecological functions, wetlands are fundamental assets to reduce levels of greenhouse gases in the atmosphere. Despite their importance, wetlands are disappearing due to drainage and conversion to agricultural lands, or are being polluted at an alarming rate. This study focused on Akgol Wetland located in the Konya Closed Basin of T...

The municipal solid waste generation is among the most threatening the global environmental health hazards. The problem of environmental pollution due to waste disposal can be overcome by selecting suitable sites. Commonly, because of simultaneous effects of social, environmental, and technical parameters on suitability of a landfill site, landfill...

The aim of this study is to create a 3 dimensional (3D) virtual reality model of Istanbul Technical University, Ayazaga Campus. The study covers 80 ha of the campus area where campus buildings are located. Unmanned Air Vehicle (UAV) is used in order to capture the aerial photographs to generate 3D point clouds which later on used for Digital Surfac...
