Demis World Map

The Demis Wold Map will overlay a map on to Google Earth that increases in detail as you zoom in. The map appear to have highway-level detail for much of the world. I believe Demis offers other versions of this map with more detail at their website.

Flash Earth Viewer

Flash Earth is a website that can easily switch between several different map sources, including Google Maps, Microsoft Virtual Earth, etc.  This KML file for Google Earth will display Flash Earth in the balloon within Google Earth based on your current location. This makes it very simple to see what the other data providers have for your current view in Google Earth.

Special Instructions

Choose Small/Medium/Large to determine the size of the Flash Earth baloon window. Then simply click on the white arrow that you will see on Google Earth. Flash Earth will pop up in the balloon.  You can then switch between the different data providers.

IARU Locator Echo

This network link will place a marker in the center of your Google Earth view that has the name of the IARU locator for that position. I’m not exactly sure what this is, something to do with amateur radio.  Looks like it works for the entire globe.

Zillow Labs Neighborhood Boundaries

Database of nearly 7,000 neighborhood boundaries in the largest cities of the US from my favorite real estate website.

Please DO NOT email me about errors or omissions in this data.  The dataset was created by Zillow.  If you want to learn more about how they created the data, check out their blog post on the subject.

Special Instructions

Simply download the KML file at the top of this post. Then select the state for which you’d like to view the neighborhood data. These are network links and will load the data when you select the state. Some (TX, CA, etc) will take longer to load than others. Texas is the largest, at around 8 megabytes.
