fconley Soars: 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. One of the most active data providers to reach the new top award, the Squadron of Biplane Spectators, goes by the handle of “fconley”. His story: "I am retired from an unrelated field, but I have loved maps and travel all my life,” says the intrepid contributor. “When I saw that USGS was looking for volunteers I immediately joined, first of all working with paper maps and quads. As digital mapping, satellite imagery, and GPS became more available I was enthralled. With the imagery now accessible it is almost like being able to travel sitting at my desk. At times, locating structures seems similar to solving puzzles or detective work. This whole project is not only enjoyable but it makes me feel that I am making a lasting and useful contribution. I am thankful for the opportunity to be involved in this fascinating endeavor." You can assist FConley along with hundreds of others and contribute to The National Map.

    Mapping Alaska: In a recent front-page Washington Post article, reporter Lori Montgomery described the necessity and benefits of an USGS program to map Alaska. Although the rest of the U.S. has refined and mostly current topographic maps, much of the terrain data for Alaska is more than 50 years old. The old maps have contributed to numerous safety, science and social issues. The major requirement for the new and better detailed maps is precise elevation data. To collect such data, the USGS - along with numerous state and federal partners - has initiated the 3D Elevation Program, an effort to cover all 50 states with airborne lasers (lidar) or radar (ifsar).

    3DEP in the News: The national 3D elevation program (3DEP) project is designed to satisfy the growing demand for consistent, high-quality elevation data and a wide range of other three-dimensional representations of the Nation's natural and constructed features. Among the applications that will benefit from 3DEP data are flood risk management, agriculture, water supply, homeland security, renewable energy, aviation safety, and other areas. During the past few months, 3DEP has increased visibility and importance to include a Congressional Briefing series and mentions by the Administration:

  • 3DEP Goes to Washington: Outdated and inconsistent elevation data cost lives and hinder prosperity across our Nation. Current and accurate 3D elevation data are essential to help communities cope with natural hazards, support infrastructure, ensure agricultural success, strengthen environmental decision making and bolster national security. Flood and landslide maps are just a few of the hundreds of applications benefiting from enhanced lidar data. A coordinated effort among Federal, State, local government and the private sector could meet our country’s needs for high-quality, 3D elevation data in just 8 years. The USGS will host a briefing on Capitol Hill on July 25 to further describe the importance, benefits and growing needs for 3D elevation data. http://on.doi.gov/1sLF7bE

You Can Contribute to National Mapping: This April marks the one year anniversary of the USGS's The National Map Corps (TNMCorps) transition from a small regional pilot project in the heart of Denver, Colo., into a very successful nation-wide project. During the past year, civilian volunteers in every state have increasingly provided accurate mapping data to the The National Map. Some numbers: 1,422 volunteers; 33,698 points edited; 18 volunteers who have earned more than 500 points. Earn points, get badges! http://on.doi.gov/1heH7y1

US Topo maps on Google: USGS National Geospatial Program Director Mark DeMulder, in a guest blog on the Google Enterprise website, announced that the Google Maps Gallery is now featuring US Topo maps. The interactive application allows the user to pick a location and select the desired quadrangles. The quads are downloaded directly from the USGS in GeoPDF format and can be manipulated using freely provided commercial mapping tools. The USGS is working with Google to make sure the application points to the most up to date versions of the maps. http://bit.ly/1rKroQo

Latest Utah Quads Available: More than 1,475 newly revised US Topo maps for Utah have been posted to the USGS Map Locator & Downloader and accessible through The National Map viewer. The revised maps feature new road data from Nokia. The new maps also include Public Land Survey System (PLSS) data. The PLSS is a way of subdividing and describing land in the United States. All lands in the public domain are subject to subdivision by this rectangular system of surveys, which is regulated by the U.S. Department of the Interior. Other selected states will begin getting the new transportation and PLSS map data during their next respective revision cycle. http://on.doi.gov/1nX4buM

Border Waters: The U.S. and Canada recently completed a trans-continental project to join digital surface waters along the International Boundary. This linking of water systems data makes it easier to solve cross-border water quality issues and improve environmental coordination. The principle agencies involved in this effort are the USGS and Natural Resources Canada (NRCan), with oversight by the International Joint Commission (IJC). The U.S. Environmental Protection Agency, Agricultural Foods Canada, and Environment Canada also participated throughout the process. http://on.doi.gov/N9WTDp
