Hello,

I thought that you might be interested in this. Maybe you have time for a map display? They have a web page about their festivities at: http://nationalmap.gov/125years/index.html. Linda Zellmer

"The U.S. Geological Survey is celebrating the 125th anniversary of its national program for topographic mapping (1884–2009). Topographic maps became a signature product of the USGS because the public found them—then and now—to be a versatile tool for viewing our Nation's vast landscape. During the 20th century, more than 55,000 large-scale topographic maps were published by the USGS, culminating in complete coverage of the contiguous 48 States in 1991. In the last quarter-century, the rise of the digital age, the rapid growth of Internet communications, and the technology of geographic information systems (GIS) have transformed topographic mapping science, enabling the electronic construct of The National Map of today."
