The aim of this study is to the evaluate land use and the land cover changes of an abandoned coal mine in Central Anatolia. The mining activity in the region was started at 1987 and after working for 18 years, all the rights of the mine was passed to an another company which after a while the came up with no coal production since its concession was cancelled on February 2008. Unfortunately, during the life of the mine, there were no mine closure and reclamation activities on the field. There was only a limited afforestation work on the dump site performed by provincial special administration. As there were no appropriate closure and reclamation implementations during and after the mining activity, major environmental impacts detected on the mine field. This study investigates the land use land cover change due to mining operations between 1987 and 2000. Landsat ETM+ imagery is selected. Maximum Likelihood estimation based on the Bayesian theorem is used for classification purposes. Change maps are produced to observe the differences in land use and land cover changes in the study area in comparison with the baseline of the region.


Evaluation of glaciation and glacial shapes using geographic information systems and remote sensing (Eastern Black Sea)
Geçen, Reşat; Toprak, Vedat; Tombul, Saadettin; Department of Geodetic and Geographical Information Technologies (2011)
This study investigates the actual glaciers and the major properties of glacial landscapes (valleys, cirques and lakes) located over the Eastern Black Sea mountain chain using Geographic Information Systems (GIS) and Remote Sensing (RS) technologies. A database is created for each glacial feature that includes fundamental properties of each landscape. Data layers used in the study include digital and analog topographic maps, satellite images, geological maps and drainage maps. The studies carried out yielde...
Evaluation of Site Characterizations and Site Effects of the Ankara Basin Turkey
Koçkar, Mustafa Kerem; Akgün, Haluk (2007-06-28)
The purpose of this study is to assess the in-situ site characteristics and to perform seismic hazard studies of the Upper Pliocene to Pleistocene fluvial and Quaternary alluvial and terrace deposits located towards the west of Ankara. Based on a general engineering geological, geotechnical and seismic characterization of the site, site classification systems were assigned for seismic hazard evaluations. Then, short-period noise recordings of the microtremor measurements at the ground surface have been used...

he main purpose of this research is to determine the anomalies regarding the coal mining operations in an abandoned coal mine site in central Anatolia by multi-temporal image analysis of Landsat 4-5 surface reflectance data. A wellknown anomaly detection algorithm, Reed-Xioli (RX), which calculates square of Mahalanobis metrics to calculate the likelihood ratios by normalizing the difference between the test pixel and the background to allocate anomaly pixels, is implemented across the time series. The expe...

Forests play a vital role in balancing atmospheric carbon dioxide and thereby diminish the pace of global climate change. Agriculture fights against extreme poverty and feeds a projected 9.7 billion people world population by 2050. Although these natural and agricultural lands are so important for now and the future, they have been shrinking all around the world, especially in developing countries. As in some other developing countries, many metropolitan cities face Land Use (LU)/Land Cover (LC) change in T...
Hierarchical classification of Sentinel 2-a images for land use and land cover mapping and its use for the CORINE system
Demirkan, Doga C.; Koz, Alper; Duzguna, H. Sebnem (SPIE-Intl Soc Optical Eng, 2020-06-01)
The aim of this study is to investigate the potential of the Sentinel-2 satellite for land use and land cover (LULC) mapping. The commonly known supervised classification algorithms, support vector machines (SVMs), random forest (RF), and maximum likelihood (ML) classification are adopted for investigation along with a proposed hierarchical classification model based on a coordination of information on the environment land cover system. The main classes for land cover and mapping in the proposed hierarchica...
