Changes before closing the panel.
Double-click on Layer 1 in the Maps panel to
add this layer to the active view. You can switch
between different layers of a map using the checkboxes
in front of these layers in the View Components
panel. The last one activated is always the uppermost
layer. Figure Figure 4.5 gives an example for a certain
style of the imported maps.
The remaining maps that we have loaded contain
spatial information on rivers and wells, i.e., line and
point structures. To enhance the appearance of the rivers
in the active view we change width and color of the
line, again using the Map Properties panel for the
Default layer of the map rivers.
For the map demo_wells the style settings of the
markers and for the labels can be edited separately.

Instead of showing both rivers contained in the map
rivers, we only want to plot the eastern one. To do so,
we use a SQL selection statement on the attribute field
NAME of the map to create a data selection that is limited
to the river in the east.
Open the context menu of the map rivers with a
right-click on the map and select Show Map
Table... to display the attribute data of the map in tabular
format (see Figure 4.6). For the attribute field
NAME two different data sets exist, River West and
River East. Close the Map Table dialog and now
choose Join/Select Map(s) Data... to open the Join
Maps dialog. In the input field of Select record where
enter NAME=”River East” as SQL selection statement
to select the map data for the eastern river only. Make
sure to enter the name with a capital R and E as the
SQL syntax is case sensitive.
Figure 4.6 Map Table dialog for the map rivers.
To ensure that the syntax is correct click on
Preview. The map table now only shows one
record for the River East and reflects a reduced data
selection according to the SQL statement. Leave the
Map Table dialog with Close and the Join Maps
dialog with OK. The active view now also reflects
the reduced map data set by only displaying the eastern
river.
