USA: The price of the popular USGS (U.S. Geological Survey 1:24,000 scale topographic quadrangle map – often called a “topo” or a “quad”) – will go up $2 per sheet to $8. Larger format (”poster”) maps will go up $3 per sheet to $10. These prices were last increased 7 years ago.
The USGS began a systematic program of topographic mapping in 1884 as an aid to scientific studies in geology and hydrology. Since then, the maps have become a signature product of USGS because the public has found them to be a valuable tool for accurately depicting the land surface.
The nation is covered by more than 57,000 detailed USGS topographic maps that show the shape and elevations of terrain and delineate a wide range of natural features and built structures. USGS maps are particularly useful for natural resource managers, planners, engineers, and outdoor enthusiasts. During natural disasters, such as hurricanes, floods, and earthquakes, thousands of USGS map sheets are typically rushed to the area overnight to assist emergency agencies in response and recovery efforts.
