FOS GIS solutions in Web Mapping

Free open source (FOS) solutions, to a large extent are the main driving power in changes, particularly expressed in the web sphere. Evolution of Web Services, Mashup services and free API solutions contribute to the rapid transformation of the Web in more and more interactive environment, which becomes the point of attachment of a variety of different services from which derive entirely new services. An excellent opportunity to combine different services is expressed through the Web Mapping. Various open source community contribute to the development of numerous Web-based services that are becoming unavoidable for direct use, or combination with other Web-based services. Open GIS community has made standardization and increased availability of GIS technology possible, especially through open source software, such as QGIS software package. Its use on the Internet, through GIS techniques for numerous interactive map interfaces, led to the development of separate GIS Internet service. Various open source plugins have contributed to the improvement of GIS and the way it is used. Google Layer, OGR2Layer and Open Layers are some of the important tools reviewed in this paper which are very useful for web mapping. Also, it will be described the use of GIS layers, created in open source solutions, and implemented in Google Earth application.
