2. Outline GIS data to web What is KML? Conversion of data to KMZ
Overlaying KMZ data on web (Google Earth)
Convert a kmz file to ArcGIS layer

3. 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

4. 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

5. 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
Use to convert
individual data layer

6. Conversion of data to KMZ
