Strater can import and export .KML and .KMZ files. Use the Map | Create | Base Map or Map | Add | Base Layer command to import a KML or KMZ file as a base layer.
.KML and .KMZ files are imported into Google Earth to display information, such as maps or point locations, on Google Earth maps. Both .KML and .KMZ files contain the same information. The difference is that .KMZ files are compressed versions of .KML files. When exporting to .KML or .KMZ files, images are exported to the same directory specified by the Export dialog.
.KML and .KMZ files require that the coordinates be in latitude and longitude degrees. This means that the Map object in the Object Manager is converted to lat/long (WGS84) when exporting. The program does this conversion internally. No change is needed to the Map target coordinate system.
Non-map objects must be excluded from the export for the KML/KMZ file to export the map with the correct coordinates. One method is to select the Map object in the Object Manager before clicking the File | Export | Graphic command. Next check the Selected objects only check box in the Export dialog. Another method for exporting without non-map objects is to turn off the visibility of any drawn objects (legends, polylines, etc.) by clicking the check box next to the objects in the Object Manager.
