Topic 10- GIS layers to web
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
2
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
3
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
4
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
5
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
Use to convert
map document
6
Overlaying KMZ data on web (Google Earth)

Convert to kmz in arcGIS; Open Google Earth and add the kmz file
7
Conversion of data to KMZ

Tool converts a KMZ file into an ArcGIS layer
 To access: Arctoolbox> Conversion tools> From KML> KML to Layer
Use to convert
KMZ to ArcGIS layer
