1 National Geospatial Advisory Committee THE NATIONAL MAP/ELEVATION UPDATE Gary Thompson NGAC Meeting October 5, 2011

2 National Geospatial Advisory Committee USGS Topographic Maps US Topo  The 7.5 minute topographic map series is being published on a three- year update cycle  The program has met its FY 2011 production goal of 18,000 maps  More than 50,000 new maps have been published since US Topo production began in October 2009  Downloads of the GeoPDF format Have exceeded 750,000 to date The rate of downloads is increasing

3 National Geospatial Advisory Committee  The National Geospatial Program (NGP) is converting these historical printed topographic quadrangles to electronic format (GeoPDF) Dual purpose of creating: A master catalog Digital archives copies GeoPDF map availability to the public: Now: Shown in green (90,000) Fall 2011:Shown in yellow Winter 2011-2012:Shown in blue Spring 2012:Shown in purple Summer 2012 :Shown in orange USGS Topographic Maps Historical Maps  Prior to 2009, USGS topographic maps were created using traditional cartographic methods and printed using the lithographic printing process

4 National Geospatial Advisory Committee National Enhanced Elevation Assessment Completed two important tasks during the past quarter  Inventoried existing enhanced elevation data Slightly less than 30% of the continental US has some form of improved and publically available LiDAR or IFSAR elevation data  Nearing completion of the business requirements (needs assessment) phase More than $4B in annual benefits could be realized if a national program were able to support these needs NOAA LiDAR workshop Workshop report  http://www.ngs.noaa.gov/corbin/class_description/LiDAR_HM.shtml http://www.ngs.noaa.gov/corbin/class_description/LiDAR_HM.shtml National Enhanced Elevation Assessment presentation  http://www.ngs.noaa.gov/corbin/class_description/2011_08_18_NOAA_LiDAR_Works hop_USGS_Distribution_Copy.pdf http://www.ngs.noaa.gov/corbin/class_description/2011_08_18_NOAA_LiDAR_Works hop_USGS_Distribution_Copy.pdf

5 National Geospatial Advisory Committee National Atlas/Alaska Initiative The National Atlas of the United States of America  Base map data at 1:1,000,000 scale  Coordination with Canada and Mexico  To be released in 2012 Alaska Mapping Initiative  USGS provided funding for the cooperative IFSAR acquisition project in FY 2011  Goal to modernize elevation data in Alaska
