### Data Source Selector

The Data Source Selector is used to Select an existing data source and make its content available as datasets, but firstly it is used to define a way to connect with different data sources from where to search for data. For more information about this interface, access this link.

Each type of Data Source has a set of parameters defined in an appropriate interface. If at least one data source is defined (PostGIS at this example), click on Select to see all the datasets available. The dataset names will be showed and one or more datasets can be selected to be manipulated by the application.

It is important to note that the datasets still at the original data source. Also you can combine datasets from different sources, for example you can select a shape file from a directory and a spatial table from PostGIS and draw them without any import/export action over the original data.

Click on Select and a new interface will be provide with all datasets available.
