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
