USGS
Mapping Productivity Record Slashed 21/09/2010
USGS
has exceeded its highest map cells production in one
year since the record of 2,500 new quadrangle maps were
published in 1972. Since the first release of the US
Topo series of revised digital topographic maps less
than nineteen months ago, the US Geological Survey
(USGS) has published more than 30,800 7.5-minute cells
covering more than 50% of the nation's land area and
setting standards for production efficiency.
For
the past 125 years, USGS topographic maps have provided
resource managers and the general public with
accessible, accurate geographic knowledge for uses that
range from recreation to scientific analysis to
emergency response.
To
meet the need for modern computer-accessible topographic
maps that are frequently updated, the USGS established
the new US Topo digitally-based national map series.
Modeled on the traditional, instantly recognised,
paper-based 7.5-minute topographic series, these new
maps use the best available government digital data.
A
further efficiency gain is that rather than having USGS
personnel print, distribute, and store paper copies, the
entire US Topo collection is available as digital files
and is distributed free of charge, through the Web, via
the USGS Store. Digital US Topo map files are designed
to be easily printed on demand.
Improved
production processes instituted by the USGS National
Geospatial Technical Operations Center (NGTOC) will
allow the entire contiguous US to be remapped every
three years. The USGS is on track to meet this goal.
