GIS data to web Graphic display of GIS spatial data in
applications such as Google Earth
Layers – features or raster layer converted
Map- map document converted
Process uses conversion to KML for display on web

What is KML? Keyhole Markup Language (KML)
Format to store geographic data & associated content
Share with non-GIS users on and viewed on Internet using free applications such as Google Earth
Composed of features & raster: points, lines, polygons, and imagery as well as pictures and attributes
KML files are compressed to KMZ format

Conversion of data to KMZ Tool converts a feature or raster layer into a KML file
containing a translation of Esri geometries and symbology. File is compressed using ZIP compression, has a .kmz extension Can be read by any KML client including ArcGIS Explorer, ArcGlobe, and Google Earth. To access: Arctoolbox> Conversion tools> To KML> Layer to KML

Conversion of data to KMZ Tool converts a entire map document (.mxd) into a KML file
containing a translation of Esri geometries and symbology. File is compressed using ZIP compression, has a .kmz extension Can be read by any KML client including ArcGIS Explorer, ArcGlobe, and Google Earth. To access: Arctoolbox> Conversion tools> To KML> Map to KML
