Open Geospatıal Consortıum Web Map And Feature Servıces And Free/Open Source Server/Clıent Softwares
Şanlıoğlu, İsmail
Usage of geospatial data enables decisions to be more effective and stronger in critical fields. Since geospatial data is very expensive source and the most time-consuming step, mostly it is not possible to find the required data ready to use. Therefore different projects have been developed and tried to implement by several countries to keep geospatial data which is required to collect and managed, accessible and usable. At this study Open Geospatial Consortium standarts were explained, the focus was given on WFS and WMS because of their increasing popularity. Concurrently free and/or open source WMS/WFS server and client softwares were investigated.
Mapping Urban Growth Through Landscape Expansion Index and Land Use Analysis: Evidence from Western Turkey
Gülsüm Ecem Demirdağ
This study investigates the dynamics of Land Use and Land Cover (LULC) changes along the İzmir-Denizli Highway corridor in western Turkey from 1984 to 2025, utilizing remote sensing techniques and the Landscape Expansion Index (LEI) to analyze urban growth patterns. Employing cloud-free Landsat satellite imagery and the Random Forest classification algorithm within Google Earth Engine, the research identifies and quantifies built-up area expansion over four decades. The findings reveal a significant increase in built-up areas, particularly after 2000, with a total expansion from 45682 hectares in 1984 to 68869 hectares in 2025. The analysis highlights a predominance of edge-expansion growth (71.3%), with outlying growth (27.4%) and minimal infilling growth (1.3%). This trend indicates a sh...
