6 Şubat 2023 Kahramanmaraş depremleri (Mw 7.7 ve Mw 7.6) sonrasında Türkiye’de meydana gelen depremlerin (Mw≥4) coğrafi bilgi sistemleri ile mekânsal analizi
(01.12.2023)
İnsanlar çok eski çağlardan beri doğal afetler ile karşılaşmakta ve doğal afetlerin oluşturduğu sorunlara maruz kalmaktadır. Ülkemiz bulunduğu topoğrafik, jeolojik ve iklim koşullarına bağlı olarak doğal afetlerle sürekli ...
Türkiye’de 2015 ile 2022 yılları arasında meydana gelen orman yangınlarının coğrafi bilgi sistemleri ile zamansal ve mekânsal analizi
(01.11.2023)
Dünyada orman yangınlarının can ve mal kaybına neden olan sosyal, ekonomik ve ekolojik olmak üzere maddi ve manevi birçok sonuçları vardır. Son yıllarda dünya genelinde orman yangınlarında hem sıklık hem de büyüklük açısından ...
On the Impact of GPS Multipath Correction Maps and Post-Fit Residuals on Slant Wet Delays for Tracking Severe Weather Events
(20.03.2023)
Climate change has increased the frequency and intensity of weather events with heavy precipitation, making communities worldwide more vulnerable to flash flooding. As a result, accurate fore-and nowcasting of impending ...
GPS + Galileo + BDS-3 medium to long-range single-baseline RTK: an alternative for network-based RTK?
(17.12.2023)
Thanks to the development of the real-time kinematic (RTK) algorithm and the emerging Global Navigation Satellite System (GNSS), especially for Galileo and BeiDou-3, reliable positioning accuracy for medium and long-baseline ...
Determination of periodic deformation from InSAR results using the FFT time series analysis method in Gediz Graben
(17.03.2023)
Permanent Scatterers (PS) point velocities obtained by the interferometric synthetic aperture radar (InSAR) method are generally determined using the linear regression model, which ignores periodic and seasonal effects. ...
Static and kinematic PPP-AR performance of low-cost GNSS receiver in monitoring displacements
(01.12.2023)
Recently, low-cost GNSS receivers have played a significant role in displacement monitoring studies due to the increasing availability of mass-market applications. In this work, the performance of static and kinematic ...
Investigation of the effect of height difference and geometry of GCP on position accuracy of point cloud in UAV photogrammetry
(21.02.2023)
In this study, the effect of the height difference, geometry, and number of GCPs on the positional
accuracy of point cloud was investigated in UAV photogrammetry. It has been determined that the
topographic change of the ...
