Data
Source Selector
The Data Source Selector
is used to choose an available data source and
make its content
visible as
datasets to be selected.
- Click on a Data Source type
(PostGIS, Microsoft Access, Vector File or Raster
Files).
- Choose one of the Available
Data Sources by clicking over it. If the list is
empty click on
to add one.
- Click on Select and
a new interface
will be provided with all datasets available to be selected.
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
stored in a
PostGIS database and draw
them without any import/export action over the original data.
Besides
that, the Data Source Selector
is also used to define a way to connect with different data sources
from where to search for data. Each
type of Data Source has a specific set of parameters and for each of
them there is an appropriate interface defined.
To add, remove, create a empty one, or update the connection
parameters follow the steps bellow:
- Click on to add an existing data
source as an Available Data Source and fill the
connections parameters.
- Click on
to change the
connection parameters.
- Click on
to create a new empty
data source.
-
Click
on 
to remove
the connection reference from the list.
To
fill the connections parameters for each data source type see
the Connector plugins.
Check also Tool
-> Data Source Selector to explore the data sources
already defined and also to define new ones.
There
is a file called datasources.xml which keep all information about
the data sources registered through this interface. This file is saved
into the user application data directory. In windows the path is
C:\Users\<user_name>\AppData\Local\terraview\datasources.xml.
