The National Map Corps Increasing Membership:

  • Do You Like to Map? Take the Mapping Challenge! Volunteer citizen-mappers continue to make significant contributions to the USGS ability to provide accurate mapping information to the public. Recently, volunteers were asked to update all of the law enforcement structure points in Tennessee. The volunteers answered the call and added, verified, edited, or deleted an amazing 440 points! http://on.doi.gov/1OBraWo

  • Nuclear Inspired Mapping: The USGS crowdsourcing project called The National Map Corps uses citizen scientists to validate or edit structures to improve topographic maps. To reward and recognize those volunteers, TNMCorps assigns points to the submissions which lead to virtual badges increasing awards levels. One of the more active data providers to reach the previous top award, the Theodolite Assemblage, goes by the handle of “PercMastaFTW”. His story: “I have been training to become a nuclear operator in the Navy for over a year now. Since I joined, I have been looking for some projects that I would be able to be a part of. That's when I learned about the National Map Corps. I'd say that the greatest part of this project is being able to volunteer right from my room. It feels great knowing that I'm able to use my time that I use to wind down to help out a greater cause. Being somewhat of a perfectionist, I've found an enjoyment in a niche reviewing my peer's map points, confirming data, then finally formatting the information. Thank you to the staff of the National Map Corps for always being so helpful and giving me the opportunity to partake in this great project!” You can assist PercMastaFTW, along with hundreds of others, and contribute to The National Map. Join The National Corps and begin editing points today! http://bit.ly/11e0VLu
  • Mapping Challenge: Kentucky finished, North Carolina started: The USGS National Map Corps is pleased to announce the completion of the Mapping Challenge to update, verify, add and delete 442 Law Enforcement facilities in Kentucky. Special thanks to volunteers fconley, rjerrard, TheJ. Gnooj, Carograsaurus and Kelly Margaret Gorman for their hard work and tenacity in contributing to this activity.

  • The next Mapping Challenge is now open (then closed quickly): This new task is similar to the last several challenges, and is to update all Law Enforcement and Prison/Correctional Facilities in North Carolina. This includes verifying or updating the existing points, adding missing points, and removing obsolete points. Participation in the National Map Corps Volunteer Geographic Information project is open to anyone with interest and an internet connection – so consider volunteering today! http://bit.ly/1r0J4Ki

US Topo Map and Historical Topographic Map Collection News:

  • Golden State Quads Add Trails: Newly released US Topo maps for California now feature selected trails and other substantial updates. Several of the 2,798 new US Topo quadrangles for the state now display public trails along with segments of the Pacific Crest National Scenic Trail. Also the new maps now show improved data layers such as public land survey information, map symbol redesign, enhanced railroad information and new road source data. Some of the data for the trails is provided to the USGS through a nationwide “crowdsourcing” project managed by the International Mountain Biking Association (IMBA). http://on.doi.gov/1GL6Gbg

  • More Than 18 Million Served: The USGS, through the National Geospatial Program, has delivered more than 18 million US Topo quadrangles and Historic Topographic maps in the past six years. Can you guess the top download locations? Hints: The most accessed digital US Topo map features a city with many monuments, and the most popular historical scan is in the west, dating back to 1909. For the answers to those questions, and how to download your own maps, for free, go to the most recent USGS Top Story: http://on.doi.gov/1OvyHqA

  • Show Me New Data for Show-Me State Maps: Several of the 1,196 new US Topo quadrangles for the state of Missouri will display selected trails along with other improved data layers and PLSS. The trail data is provided through a partnership with the International Mountain Biking Association (IMBA) and MTB Project. During the past two years, the IMBA has been building a detailed national database of mountain bike trails with the aid and support of the MTB Project. This “crowdsourced” activity allows local IMBA chapters, IMBA members, and the public to provide trail data and descriptions through their website. http://on.doi.gov/1G2eseC

Copper Engravings for Sale: From the 1880s to the 1950s, the USGS used engraved copper plates as part of the process to print topographic maps, geologic maps and other scientific illustrations. Thousands of these hand-crafted engravings were used, but eventually replaced by advances in mapping and printing technologies. To clear the aging inventory, the USGS first offered the engraved plates to Federal, state and nonprofit organizations. After that process, the General Services Agency is now selling the remaining sets to the public. More information: http://on.doi.gov/1BJbk43

3DEP Moving Forward:

    Latest 3DEP State Fact Sheets: During the past month, the 3D Elevation Program, known as 3DEP has added two more states to its rapidly growing selection of state-specific fact sheets that features the applications, benefits, and examples of 3DEP. Iowa, Pennsylvania, West Virginia, and Nevada join the mounting list of 47 state Fact Sheets. All are available for viewing and download from The National Map or 3DEP websites.

  • First Round of Lidar BAA Awards Released: The USGS National Geospatial Program has announced the first round of awards resulting from the USGS Broad Area Announcement (BAA) for the 3D Elevation Program (3DEP), initially issued on July 18, 2014. The BAA is a publicly accessible process to develop partnerships for the collection of lidar and derived elevation data for 3DEP. The primary goal of 3DEP is to systematically collect nationwide lidar coverage (ifsar in Alaska) over an 8-year period to provide more than $690 million annually in new benefits to government entities, the private sector and citizens. 3DEP presents a unique opportunity for collaboration between all levels of government to leverage the services and expertise of private sector mapping firms that acquire the data, and to create jobs now and in the future. http://on.doi.gov/18X6HLE

Landsat Data Easier to Access and Visualize: Although Landsat data has been free to the public since 2008, Amazon Web Services (AWS) has recently made the vast collection of Landsat imagery easier to obtain and customize with several web services. Users can now access the more than 85,000 Landsat 8 scenes through the AWS Public Data Set. The Landsat program of Earth observation, conducted jointly by USGS and NASA, creates moderate-resolution satellite imagery of all land on Earth every 16 days. The program has been running since 1972, the longest ongoing project to collect land imagery. Landsat data are the foundation for research and applications in many global sectors, including agriculture, cartography, geology, forestry, regional planning, disaster response, and education.

How Pittsburgh got its “H” Back: In 1891, the U.S. Board on Geographic Names (USGN), acting on a request of the Postal Service, eliminated the “h” from the end of Pittsburgh, mainly to save space. Unlike most other USGN decisions, this action to standardize names across the federal government did not sit well with many prominent Pittsburgh institutions and residents. Under some consistent petitioning and references to historical documentation, the Board reinstated the Steel City’s “h’ on July 19, 1911. However, there are still some artifacts and publications that have the “h” missing. Summary: http://bit.ly/1E9aIaP

Happy Birthday JWP: March 24 marks the birthday of John Wesley Powell (born 1834). Powell was a prominent scientist, explorer, geographer, and even lost an arm as a Civil War hero. He is recognized as one of the leaders of national topographic mapping and was the 2nd director of the USGS. In 1894, to gain funding for a systematic study and classification of the nation’s increasing lands, Powell said to Congress, “A Government cannot do any scientific work of more value to the people at large than by causing the construction of proper topographic maps of the country.” After leaving the USGS, Powell helped establish the National Geographic Society and is a past president of the American Association for the Advancement of Science. Hat’s off to you, Major Powell! http://on.doi.gov/1FzQ1Ir
