There is plenty you can learn about an area, just by looking at its maps. And no, I am not just talking about locations like the best place to get a bite to eat. I am talking about history. You can really understand the history of a place, when you look at the historic maps that are available to you, and it is all thanks to free public domain data. Public domain data is information that is free for public use, like online maps.
Doing some light examination of the Denver West area (Lakewood, Golden, in Colorado.), the following historic maps and imagery, referenced below, are just two aspects of free public domain data. There is so much more beyond imagery and maps, and even more maps and more imagery (i.e. MODIS, LANDSAT, other NASA products). So if you think you are up to the task, read on, and learn a little more about the Denver West area through its historic maps.
