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

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

5

Use to convertindividual data layer

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
