Shapefile to Google Earth kml - Customize Symbol Properties and Labeling (NO PROGRAMMING REQUIRED!)

Step 1:  Choose your input file and coordinate system.

Step 2: Decide which attribute you want to use as the label and check 'Mouse Roll over Effect' if you want to highlight a feature when the mouse is moved over it.

Step 3: Decide what color and transparency (opacity) you features will be.

Step 4: Decide what attribute information you would like in the pop-up balloon when a feature is clicked or selected and customize the balloons symbology.

Step 5: Give the kml layer a name and any descriptive information you would like and your done!
