Web mapping client comparison v.6

In the sixth version a number of projects have been added and the whole set of clients has been categorized in order to distinguish them better, since there are currently forty four (44) Web mapping clients in the comparison. Web mapping clients play a significant role in Geoportals of Spatial Data Infrastructures (SDI) allowing the visualization of spatial data from several sources. Likewise, these clients may be part of Web-based Geographic Information Systems (GIS) applications, in which users can directly interact with SDI services, visualize, query and integrate them with local data and GIS tools. There exists a wide variety of free and open source software (FOSS) projects that make the creation and configuration of Web mapping clients easier.

The clients access the system by interacting with the user interface layers that takes the input and shows the output of the system. It involves graphical user interface therefore it must be designed cautiously so that the user can understand it easily. The application layer provides the map visualization functions like panning, zooming etc. It provides the others functions also like layer selection, editing, querying etc (Lu, 2005). The database layer handles the data present at distributed sources. Et al. Thin Client In this the processing power lies in the server. . , 2002) The server system has centralized control on all resources therefore it is easy to update.
