INTViewer for Plugin Developers - Working with GIS data

Working with GIS data

Note: You will need to include GisData to your Module Dependencies list.

GIS data files supported by INTViewer are in the *.shp and *.dxf formats.

A GIS data file can be loaded as follows:

    import com.interactive.intviewerapi.data.IData;

    import com.interactive.intviewerapi.data.gis.IGisData;

    import com.interactive.intviewerapi.util.DialogManager;

...

        IGisData gisData = null;

        try {

            gisData = IData.factory.createNewInstance("/data/GIS/cities.shp", IGisData.class);

        } catch (Exception ex) {

            DialogManager.getDefault().showMessageDialog("Error loading GIS data file cities.shp.",

                    "Error Loading GIS Data File", DialogManager.ERROR);

            return;

To select one dataset:

   import com.interactive.intviewerapi.data.ISingleDataChooser;

   // get the chooser for gis data type

   ISingleDataChooser<IGisData> singleChooser = ISingleDataChooser.Factory.createNewInstance(IDataChooser.GIS);

   // popup the chooser dialog

   int rc = singleChooser.setDataChooserVisible(true);

   if (rc == JFileChooser.APPROVE_OPTION) {

      IGisData gisData = singleChooser.getSelectedData();

To select multiple datasets:

   import com.interactive.intviewerapi.data.IMultipleDataChooser;

   // get the file chooser for gis data type

   IMultipleDataChooser<IGisData> multipleChooser = IMultipleDataChooser.Factory.createNewInstance(IDataChooser.GIS);

   // popup the chooser dialog

   int rc = multipleChooser.setDataChooserVisible(true);

   if (rc == JFileChooser.APPROVE_OPTION) {

      for (IGisData gisData : multipleChooser.getSelectedData()) {
