An overview of the KML toolset

The KML toolset contains tools to convert Keyhole Markup Language (KML) to layers and feature classes, and maps and layers to KML.

KML is an XML-based language provided by Google for defining the graphic display of spatial data in applications such as Google Earth and Google Maps. KML enables these applications to support the open integration of custom data layers of GIS users.

KML is a popular format for sharing data across the internet and for use in online mapping applications. Its default projection of WGS84 allows it to be displayed and used in a variety of GIS applications. Translating .kml and .kmz files into feature classes in a geodatabase allow these features to be used in ArcGIS.

Tools in the KML toolset

Tool	Description
KML To Geodatabase	Converts a .kml or .kmz file to the appropriate point, polyline, or polygon outputs.
KML To Layer	Converts a .kml or .kmz file into datasets in a geodatabase and a layer file. The layer file maintains the symbology of the input .kml or .kmz file.
Layer To KML	Converts a feature or raster layer to KML format (.kmz or .kml file). The output KML will contain a translation of Esri feature geometries, raster cells, layer symbology, and other properties.
Map To KML	Converts a map containing feature or raster layers to KML format (.kmz file). The output KML will contain a translation of Esri feature geometries, raster cells, layer symbology, and other properties.
