National Map Products and Services for the Empire State: For almost ten years, The National Map viewer has served as one of the more prominent and visible products of the National Geospatial Program (NGP). It represents a significant collaborative effort between the USGS and other Federal, State, and local partners in disseminating nationwide geospatial data, and where available, content from state and local sources as well. Sam Wear, from the Westchestor County CIO, points out how New York citizens, and any other state for that matter, can benefit from the free TNM data.

Mapping the National Parks: The National Parks of the United States are often compared to, and indeed inspire, works of art. We at USGS certainly are inspired by the parks, and, since our founding in 1879, we’ve been regularly contributing new and updated works of art for the national parks—maps. From the classic topographic maps you use to hike the trails, to the cutting edge lidar maps used to track landslide hazards, we’ve got thousands of different maps covering all the national parks, no matter their size.

Mountain Biking and Mapping: The International Mountain Bike Association has assisted in the gathering and integration of trail data into The National Map and US Topo map products. Last fall, USGS Systems Development Branch Chief, Brian Fox, joined a few IMBA members on a series of trail rides. The trips focused on Bureau of Land Management properties in California and Oregon. The treks, along with several maps and pictures, can be viewed at this Story Map:

NEW Mapping Challenge – Pennsylvania Law Enforcement: For the new challenge, The National Map Corps is jumping back into updating Law Enforcement Facilities, this time in Pennsylvania, in advance of US Topo map updates for the state. This is the project’s biggest mapping challenge yet, with more than 700 unedited existing points that need to be checked, and 180 points that need to be peer reviewed or verified by an advanced editor. Participating in a challenge includes verifying or updating the existing points, adding missing points, and removing obsolete points. Volunteers who contribute in the challenge area will be recognized on this page and also tweeted on The National Map Twitter account. Happy Mapping!

US Topo Update: The availability of US Topo maps has reached its third "cycle." That means that each USGS quadrangle in the U.S. and appropriate territories is entering its third revision phase. Alaska is the lone exclusion, and is covered as part of the Alaska Mapping Initiative. The production and release of US Topo maps started in October 2009. In October 2012, the project has met its very aggressive long term goal of replacing all quads in the lower 48 states in three years with the new GeoPDF maps. The National Geospatial Technical Operations Center reports the following US Topo maps are loaded to the Map Locator of the USGS Store (as of 02-03-16):
  • Wisconsin: 100% complete - 1,108 quadrangles
  • Iowa: 100% complete - 1,011 quadrangles
  • Kansas: 98% complete - 1,384 quadrangles
  • Oklahoma: 39% complete – 457 quadrangles
  • Texas: 0% complete – 0 quadrangles
