KML/KMZ Google Earth Keyhole Markup File Description

Surfer can import and export .KML and .KMZ files. Surfer exports KMZ/KML with TIFF images, which is not supported by all applications.

.KML and .KMZ files require that the coordinates be in latitude and longitude degrees. This means that the Map object in the Contents window is converted to lat/long (WGS84) when exporting. The program does this conversion internally. No change is needed to the Map. Note: It is important to the Scaling source is Map in the Export OptionsScaling page. If the Scaling source is Paper space (page units) the map will end up in Africa.


The first and second attributes for polyline, polygon, and symbol objects are automatically exported to all .KML and .KMZ files. The first attribute is used for object names. The second attribute is used for an object's description. For contour maps, the elevation is exported to the polyline object name for all polylines in the contour map.
