“Today you may notice that the United States looks a bit different in Google Maps — all of that new green park land was probably a giveaway. That’s because we’ve worked directly with a wide range of authoritative information sources to create a new base map dataset. In our experience, these organizations that create the data do the best job of keeping it accurate and up-to-date. For example, in the US there are a number of publicly accessible geospatial datasets created by the government for the Census, land surveying, and transportation. These datasets provide information on everything from road networks and water bodies to toll roads and bridges. By integrating this information, and working with specialized data sources like the USDA Forest Service’s Forest Boundaries and the US Geological Survey’s National Hydrography Dataset, we’ve been able to expand and improve features in our maps like parks and water bodies….
The best part about this new dataset is that we’ve been able to add a lot of new, detailed information to Google Maps - information that helps people better explore and get around the real world. For example, college students will be pleased to see maps of many campuses; and cyclists will now find many more trails and paths to explore. Soon we even plan on providing you with biking directions to take advantage of this new data. “
A quick look shows a definite improvement in the display of forest service roads in some of my favorite National Forests. Google is also making it possible for users to suggest updates/corrections to Google. Way to go Google!
