I generated several maps to learn a bit about the differences between use of Google's Fusion Tables and the Google Map Engine Lite.
I used Fusion Tables with this first one.... direct link to a full screen view in a new window.
Then, Map Engine Lite for this one... direct link offers a full screen view in a new window.
The pins are color coded to reflect their date of origin. You can check or uncheck the boxes corresponding to the respective decades. Select a specific pin and a pop-up will display with the name of the institution, the location, and the founding date.
The dates are drawn from Table 2-Statistics of Commercial and Business Colleges 1889-1890, Part I, found in The Education Report from Vol. II of the Report of the Secretary of the Interior, Washington, DC: Government Printing Office, 1893.
These are my first baby steps with creating maps that can be embedded in a Blogger post, so I'll appreciate suggestions and feedback!!
