Mapping with Google Earth

Google Earth (GE) is a simple interface that users of all skills can use to view map layers.  GE provides the base with 3D structure layers, aerial landscape photography, borders, rivers, lakes, oceans, and just about anything you can think to want in a map.  What's more is that GE can import additional layers that you map in other programs like ArcGIS. 

This week we used Google Earth to revisit our Dot Density Population map of Southern Florida.  The dot density layers that were created in ArcGIS were converted to the .kmz format that GE uses.  The two layers were: 1.  Entire map containing dots depicting populations, water features were included as well and 2.  Layer that dot density was derived from that showed different information in GE.

The second layer did not show the dot densities in GE.  Instead, when a county was clicked on, like Miami-Dade County in the screenshot below, it would display the information for that country.

The next task we completed in this lab was to create a tour using our existing dot density layers and visiting different points around southern Florida.  The map itself with the dot density layer looked like this:


Additional points were added in GE for reference when creating the tour.  The tour started from the view in the screenshot above, depicting the population dot density for the region as well as highlighting the different water features.  It then hops from Miami to Fort Lauderdale and then moves west across the state to St. Petersburg and Tampa.  I tried to give different perspectives throughout the tour and as hard as I tried, things weren't exactly smooth.  Once the tour was completed, it was added to the overall .kmz package in GE to complete the project.  I was even able to convert/export the movie to a .mp4 format and you all get the exclusive viewing, just click to watch below.
