Example #5 - Combine three KML data sets and display in Google Earth

We'll create a map showing Cook County fishing lakes, Metra stations, and Metra lines.  Let's say you want to go fishing.  You can use the resulting map to look for lakes that are close to Metra stops.

We'll download KML files from the data portal and load them into Google Earth to create the map.  These are files that show the shapes of things.  In the previous examples, we create Google Maps showing points of graffiti.  In this map, we'll show the outline of the fishing lakes and the rail lines.

Here's a screen shot of the map.  The lake is in bright blue.  The station is the red 'X'.  The rail line is shown as the solid black line.

This map doesn't display in your web browser.  It is shown using your own copy of Google Earth.  If you don't have a copy, you can download one from the Google Earth download page.

Ready to watch?  Here's a link to the YouTube video.
