Hello everyone

Here are a few mapping-related announcements that you may be interested in:

  • National Hydrography Dataset (NHD) releases Web HEM Tool.  HEM stands for Hydrography Event Management and is a tool developed to help relate users’ data to the NHD network as events.  Please see announcement on pages 4 and 5 in the latest NHD Newsletter here:
  • New urban imagery is now available for a number of California cities.  The datasets are natural color and have a one foot resolution.  The data cover the Fresno, Modesto, Oxnard, Stockton, and Sacramento urban areas.  Data can be downloaded through the EarthExplorer site: (all cities) and The National Map Viewer site: (all except Modesto).
  • USTopo maps go into production for CA and NV in December, 2014. Please consider validating structure points (hospitals, post offices, schools, etc.) through our National Map Corps program. Watch for upcoming webinars. [Additional note: these new edition maps will include PLSS information.]
