Open Geospatial Consortium Web Map and Feature Services and Free/Open Source Server/Client Softwares

Abstract

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.

Ulusal Coğrafi Bilgi Sistemi Ulaşım Veri Temasının Katılımcı Coğrafi Bilgi Yaklaşımıyla Güncellenmesi

“…Bu soruda kurum temsilcileri birden çok formatta veriyi paylaşabileceklerinden dolayı, birden çok format seçme hakkı da tanınmıştır. Açık standartları dayalı veri paylaşım ortamının oluşturulmasının coğrafi veri ile ilişki sektörleri olumlu etkileyeceği değerlendirilmektedir (Varol ve Şanlıoğlu, 2017).…”

Possible contributions of spatial semantic methods and technologies to multi-representation spatial database paradigm

“…Communication between different systems can be ensured by protocols such as Ethernet, Transmission Control Protocol/ Internet Protocol (TCP/IP) and Hypertext Transfer Protocol (HTTP). The use of these protocols also removes heterogeneity problems of systems at the same time (Brodeur, 2012;Varol et al, 2017). But semantic heterogeneity problem needs more complex solutions.…”
