GoogleEarth

The export format „GoogleEarth (*.kml)“ on dialog File|Export enables to export the objects geometry (e.g. buildings and roads) and the grid to GoogleEarth (by Google Inc., Mountain View CA, USA).

Via the button „Options“ several additional features are available.

Options for GoogleEarth-Export

Further export procedures can easily be started with the present settings by clicking onto the export symbol on the toolbar.

Export Range

Specify whether the export range shall cover the entire limits, the present window or an existing section. In the latter case, the respective section can be selected from the list box.

Make sure that with the object modes „2D“ and „3D“ (see below) the export range '“Limits“ is selected.

Object Mode

Select whether just a screenshot or the 2D- or 3D-objects shall be exported.

In object mode „Screenshot only“ the specified range is exported as a transparent bitmap. In GoogleEarth, the satellite images are still visible on the background enabling to assess the correct location of CadnaA-objects. In 2D-mode the objects are displayed as non-transparent areas in GoogleEarth. In 3D-mode the object’s heights are exported as well. The result is a realistic 3D-representation allowing to navigate freely using all navigation tools GoogleEarth provides.

Option „with Attributes“

With this option activated the object’s attributes are exported into a table which is attached to each object displayed in GoogleEarth (see „Places“ list, expand item „CadnaA“). Upon a double-click on the baseline of an object (e.g. a road) the attribute table is displayed in GoogleEarth.

Export Grid

With this option activated an existing horizontal grid will be exported as a real raster (with or w/o progressive colors, see Grid Appearance) with transparency.

Write compressed KMZ-file

The file format KMZ („KML-Zipped“) is a compressed version of the KML-file. Besides coordinate data it contains also images. The file size of KMZ-files without images will be much smaller than the equivalent KML file.

Start KML-Viewer

Activate this option to automatically start the KML-viewer registered on your system after export (normally: GoogleEarth).

Global Coordinate System

A correct export to GoogleEarth requires object coordinates in a known coordinate system. Click on the button „Global Coordinate System“. For project files a national or international coordinate system of which has been specified will be displayed on the subsequent dialog Coordinate System (description of dialog see Coordinate System). Otherwise, select the present coordinate system as been used in the CadnaA-file. With the option „User-defined Coordinate Systems“ activated just those are listed.
