Usage Of Underground Space For 3D Cadastre Purposes And Related Problems In Turkey
(2008)Modern cities have been trying to meet their needs for space by using not only surface structures but also by considering subsurface space use. It is also anticipated that without planning of underground spaces for supporting ... -
Environmental Harmony And Evaluation Of Advertisement Billboards With Digital Photogrammetry Technique And Gis Capabilities: A Case Study In The City Of Ankara
(2008)Geographical Information Systems (GIS) have been gaining a growing interest in Turkey. Many local governments and public agencies have been struggling to set up such systems to serve the needs and meet public requirements. ... -
Evaluation Of Different Outlier Detection Methods For Gps Networks
(Mdpi, 2008)GPS (Global Positioning System) devices can be used in many applications which require accurate point positioning in geosciences. Accuracy of GPS decreases due to outliers resulted from the errors inherent in GPS observations. ... -
Automatic Retrieval of Near Photo-Realistic Textures from Single Ground-Level Building Images
(Copernicus Gesellschaft Mbh, 2010)An approach is presented for the automatic retrieval of near photo-realistic textures from single ground-level building images. First, the building facade texture is extracted using the Watershed segmentation technique, ... -
Building Extraction from High Resolution Satellite Images Using Hough Transform
(Copernicus Gesellschaft Mbh, 2010)An approach was developed for the automatic extraction of the rectangular and circular shaped buildings from high resolution satellite imagery using Hough transform. First, the candidate building patches are detected from ... -
Automatic Segmentation Of Colon Glands Using Object-Graphs
(Elsevier Science Bv, 2010)Gland segmentation is an important step to automate the analysis of biopsies that contain glandular structures. However, this remains a challenging problem as the variation in staining, fixation, and sectioning procedures ... -
Building Detection From Pan-Sharpened Ikonos Imagery Through Support Vector Machines Classification
(Copernicus Gesellschaft Mbh, 2010)An approach is presented for detecting the buildings from high resolution pan-sharpened IKONOS imagery through binary Support Vector Machines (SVM) classification. In addition to original spectral bands, the bands nDSM ... -
Defining Dynamic Spatio-Temporal Neighbourhood Of Network Data
(Copernicus Gesellschaft Mbh, 2010)To improve the accuracy and efficiency of space-time analysis, spatio-temporal neighbourhoods (STNs) should be investigated and analysed in the classification, prediction and outlier detection of space-time data. So far ... -
Tectonic Implications of Fluvial Incision and Pediment Deformation at the Northern Margin of the Central Anatolian Plateau Based on Multiple Cosmogenic Nuclides
(Amer Geophysical Union, 2013)We document Quaternary fluvial incision driven by fault-controlled surface deformation in the inverted intermontane Gok ��rmak Basin in the Central Pontide mountains along the northern margin of the Central ... -
An Approach for the Automatic Detection of Agricultural Field Sub-boundaries from High Resolution Satellite Images
(Fen Bilimleri Enstitüsü, 2014)Agricultural crop mapping is quite important for crop yield estimation in regional and national scale. Remote sensing images are popular data to identify and classify land cover types in the agricultural areas. The recent ... -
Spatio-Temporal Clustering For Non-Recurrent Traffic Congestion Detection On Urban Road Networks
(Pergamon-Elsevier Science Ltd, 2014)Non-Recurrent Congestion events (NRCs) frustrate commuters, companies and traffic operators because they cause unexpected delays. Most existing studies consider NRCs to be an outcome of incidents on motorways. The differences ... -
An Approach for the Automatic Segmentation of High Resolution Satellite Images into Agricultural Fields
(Fen Bilimleri Enstitüsü, 2015)Monitoring and management of land use plays an important role in the economic development of agriculture regions in the world. Satellite images have become very popular data source for crop mapping in agricultural areas. ... -
Change Detectıon of Buildings from High Resolution Satellite Imagery and Existing Map Data Using Object Based Classification
(Fen Bilimleri Enstitüsü, 2015)The automatic and accurate detection of buildings and the changes of buildings in urban environment is important for the efficient updating of geographic databases, decision makers, urban planning and management. In this ... -
An Approach for Automatic Building Extraction from High Resoluiıon Satellite Images Using Shadow Analysis and Active Contours Model
(Fen Bilimleri Enstitüsü, 2015)Building extraction is an important task for detecting the changes of buildings, detecting the destroyed buildings, updating the vector maps as well as reconstructing 3D building models. Satellite and airborne images are ... -
Road and Roadside Feature Extraction Using Imagery and Lidar Data For Transportation Operation
(Copernicus Gesellschaft Mbh, 2015)Transportation agencies require up-to-date, reliable, and feasibly acquired information on road geometry and features within proximity to the roads as input for evaluating and prioritizing new or improvement road projects. ... -
Geometric Quality Analysis Of Avhrr Orthoimages
(Mdpi, 2015)The geometric accuracy of 2008 AVHRR orthoimages from Metop-A, NOAA-17 and NOAA-18 satellites over Switzerland have been investigated here. The methods employed in the study are fully automated, with an accuracy of 0.1-0.2 ... -
A Min-Cut Based Filter for Airborne Lidar Data
(Copernicus Gesellschaft Mbh, 2016)LiDAR (Light Detection and Ranging) is a routinely employed technology as a 3-D data collection technique for topographic mapping. Conventional workflows for analyzing LiDAR data require the ground to be determined prior ... -
How Travel Demand Affects Detection Of Non-Recurrent Traffic Congestion On Urban Road Networks
(Copernicus Gesellschaft Mbh, 2016)Occurrence of non-recurrent traffic congestion hinders the economic activity of a city, as travellers could miss appointments or be late for work or important meetings. Similarly, for shippers, unexpected delays may disrupt ... -
