KML Database Export

Export map image can be preferable since you can combine several databases in one KML file, or you can clean up KML exports within Google Earth.  This will not give you any of the database information.

  Folder name:
Folder description
:

Set Name field from the database that will appear for each record, and will label records on the map.  This should be short text.  You can make it blank if you do not want Google Earth to label the images.

Separate layers: you can filter the database, and get each unique value of the field as a separate export.

Image.  Set links to image (on the hard disk, from an image field in the data base).  You can embed  images, or a thumbnail with link to full sized image, or just the thumbnail.  Google Earth does not do a very good job with large images, so you should consider the thumbnail options.  The thumbnails will be copied to the KML directory, and  embedded in the KMZ file.

If you use thumbnails, set the height in pixels.

Web site.  Set links to web page.

Icon.  Symbol displayed in Google Earth.  Icon scale factor determines how large they will be.  The icon will be your own image instead of the default push pin.  This can be from:

  • ICON fields in the database.
  • Pick Icon, which uses the same icon for all  records.  This is particularly effective if you export the database multiple times with different filters, and can use a different icon for each filter.

Text.  Put text file (with graphics and links) into the pop-ups in KML display.  The HTML file must be named in the field you select here; by default the program looks for the TEXT field.  If your HTML is hand tuned, you can avoid cleaning up HTML.

Use timeline with TIME fields in the database. 

Table with attributes puts a table in the KML when you select a record.  This can put the images in twice.

KML files are saved in a c:\mapdata\KML directory, with each export saved in a new sequentially numbered subdirectory.  You can find either the KMZ file there, or the KML file and all its associated imagery.  It is usually much simpler to just save the output from Google Earth to whatever location you want.
