Package kml provides convenience methods for creating and writing KML documents.

Key Features

  • Simple API for building arbitrarily complex KML documents.
  • Support for all KML elements, including Google Earth gx: extensions.
  • Compatibilty with the standard library encoding/xml package.
  • Pretty (neatly indented) and compact (minimum size) output formats.
  • Support for shared Style and StyleMap elements.
  • Simple mapping between functions and KML elements.
  • Convenience functions for using standard KML icons.
  • Convenience functions for spherical geometry.

Example

func ExampleKML() {
    k := kml.KML(
        kml.Placemark(
            kml.Name("Simple placemark"),
            kml.Description("Attached to the ground. Intelligently places itself at the height of the underlying terrain."),
            kml.Point(
                kml.Coordinates(kml.Coordinate{Lon: -122.0822035425683, Lat: 37.42228990140251}),
            ),
        ),
    )
    if err := k.WriteIndent(os.Stdout, "", "  "); err != nil {
        log.Fatal(err)
    }
}

Output:

<?xml version="1.0" encoding="UTF-8"?>
<kml xmlns="http://www.opengis.net/kml/2.2">
  <Placemark>
    <name>Simple placemark</name>
    <description>Attached to the ground. Intelligently places itself at the height of the underlying terrain.</description>
    <Point>
      <coordinates>-122.0822035425683,37.42228990140251</coordinates>
    </Point>
  </Placemark>
</kml>

There are more examples in the documentation corresponding to the examples in the KML tutorial.

Overview

Package kml provides convenience methods for creating and writing KML documents.

See https://developers.google.com/kml/

Goals

- Convenient API for creating both simple and complex KML documents.
- 1:1 mapping between functions and KML elements.

Non-goals

- Protection against generating invalid documents.
- Concealment of KML complexity.
- Fine-grained control over generated XML.
