GDF

Geographic Data Format (GDF) as used in TeleAtlas MultiNet and generic European GDF use.  GDF files provide vector data with projection information, so they are imported as drawings with the initial coordinate system correctly assigned.   GDF files often have a complicated structure of folder, tables and drawings.

To import from GDF format:

 

  1. Choose File-Import from the main menu.

  2. In the Import dialog browse to the folder containing data of interest.

  3. Double-click the file ending in .gdf for the data of interest.

  4. A variety of folders, tables and drawings will be created.

We can double-click on drawings or tables that are created to view them.   For a more interesting display, we first create a new data source using a Bing street maps image server as shown in the Example: An Imageserver Tutorial topic.   We then create a map and drag and drop the Bing layer into the map, and then we drag and drop a drawing into the map.

In the above, we have dropped the Line Features Drawing into the map.   It appears using the correct projection, using default formatting.

We can zoom in for a closer look.  The drawing shows road lines in Frankfurt, Germany.
