Layer To KML



Layer To KML


Summary

This tool converts a feature or raster layer into a KML file containing a translation of Esri geometries and symbology. This file is compressed using ZIP compression, has a .kmz extension, and can be read by any KML client including ArcGIS Explorer, ArcGlobe, and Google Earth.

Usage

  • You can control the appearance of KML in two ways:
    • By default, the pop-up display will be composed of all visible fields from the layer. Pop-up displays can also be set using the layer's customized pop-ups. If the layer pop-ups have not been customized, the values in the feature layer's PopupInfo field will be shown in the pop-up display when a KML feature is clicked. These values can be numeric or text attributes as well as HTML-formatted code stored in a text field.
    • When the layer properties are not set and the feature class contains certain attributes (fields), the field properties will be used in creating the KML. Layers that were originally created using the KML To Layer tool have attributes that define how KML will be created. See Convert to and from KML for more information on creating KML from attributes.
  • You can reduce the size of the output KMZ document if your layer has scale-dependent display properties and you choose an appropriate map output scale.
  • All KML and KMZ files are created in the WGS84 coordinate system. You need to be sure your layers will properly project if they aren't already in WGS84. You can use the Project tool to reproject your data prior to KML conversion if your projection requires a transformation.
  • To output a single raster image draped over topography, use the Return single composite image option.
  • Input features with attachments will be included in the output .kmz file. Be aware of the following conditions for attachments inside .kmz files.
    • Attachments can dramatically increase the output file size.
    • When consuming the KML file in a KML client, attachments are available from the KML pop-up.
    • Attachments can be excluded by disabling the Maintain Attachments environment setting prior to running the tool.
    • Not all KML clients support displaying attachments equally. Some KML client applications have better support for attachments like images and PDFs.
