Creating a data source from a VMAP database

To use tiling:

Load data with tiling:

IlvVMAPDataSource source = new IlvVMAPDataSource(fileName);
source.setManager(getView().getManager());

VMAPs can be loaded with or without a tiling mechanism. When using tiling, data is loaded in a background thread:

To select features to Import using FACC codes:

VMAP data contains many different features. Select the features to import into your map by choosing the appropriate FACC code:
```
source.setFaccCodeList stringTable;
```

To select the area of interest:

You can restrict the area you want to import (typical VMAP Data level 0 spans a continent) by choosing latitude and longitude bounds. For example, JViews Maps for Defense provides a bean to let users select their own areas:

// Building GUI.
cPanel = IlvCoordinatePanelFactory.
   createCoordRectangleInputPanel(view,prefs.getCoordinateFormatter());
...
// When user presses OK.
source.setAreaOfinterest(cPanel.getLonMin(),cPanel.getLatMin(),
   cPanel.getLonMax(),cPanel.getLatMax());

To use load-on-demand

You can use a load-on-demand tiling mechanism with VMAP data by setting the data source tiling parameters, for example:
```
source.setTilingParameters(true,numRows,numColumns);
```
