US Topo maps now have a crisper, cleaner design - enhancing readability of maps for online and printed use. Map symbols are easier to read over the digital aerial photograph layer whether the imagery is turned on or off. Improvements to symbol definitions (color, line thickness, line symbols, area fills), layer order, and annotation fonts are additional features of this latest update. The maps also have transparency for some features and layers to increase visibility of multiple competing layers.

This new design was launched earlier this year and is now part of the new US Topo quadrangles for Alabama (840 maps), replacing the first edition US Topo maps for the states.

"Users in our state are very excited about the three year revision cycle of the US Topo maps,” said George Heleine, the Geospatial Liaison for Alabama and Mississippi.  “The Alabama Department of Transportation says that due to increased growth within the state, updated maps will significantly increase their utility across all disciplines within State Government”. 

US Topo maps are updated every three years. The initial round of the 48 conterminous states coverage was completed in September of 2012.  Hawaii and Puerto Rico maps have recently been added. Nearly 1,000 new US Topo maps for Alaska have been added to the USGS Map Locator & Downloader, but will take several years to complete.

Re-design enhancements and new features:

  • Crisper, cleaner design improves online and printed readability while retaining the look and feel of traditional USGS topographic maps
  • New functional road classification schema has been applied
  • A slight screening (transparency) has been applied to some features to enhance visibility of multiple competing layers
  • Updated free fonts that support diacritics
  • New PDF Legend attachment
  • Metadata formatted to support multiple browsers
  • New shaded relief layer for enhanced view of the terrain
  • Military installation boundaries, post offices and cemeteries
  • The railroad dataset is much more complete

The previous versions of US Topo maps for these states, published in 2011, can still be downloaded from USGS web sites. Also, scanned images of older topographic maps from the period 1884-2006 can be downloaded from the USGS Historical Topographic Map Collection. These scanned images of legacy paper maps are available for free download from The National Map and the USGS Map Locator & Downloader website

US Topo maps are created from geographic datasets in The National Map, and deliver visible content such as high-resolution aerial photography, which was not available on older paper-based topographic maps. The new US Topo maps also provide modern technical advantages that support wider and faster public distribution and on-screen geographic analysis tools for users. The new digital electronic topographic maps are delivered in GeoPDF ® image software format and may be viewed using Adobe Reader, available as a no-cost download.

Interior, Agriculture Departments Partner to Measure Conservation Impacts on Water Quality

October 21, 2014 - 06:57
Summary: The United States Department of the Interior (DOI) and the U.S. Department of Agriculture (USDA) announced a new partnership agreement today that will provide a clearer picture of the benefits of farmers' conservation practices on the quality of our Nation's water

ALTON, Ill., Oct. 21, 2014—The United States Department of the Interior (DOI) and the U.S. Department of Agriculture (USDA) announced a new partnership agreement today that will provide a clearer picture of the benefits of farmers' conservation practices on the quality of our Nation's water.  Working together, USDA's NRCS and DOI's USGS will quantify the benefits of voluntary agricultural practices at a watershed scale.  This information will strengthen the effectiveness of state and federal nutrient reduction strategies while protecting the privacy of individual farmers.  The agreement was announced at the Mississippi River Gulf of Mexico Watershed Nutrient Task Force Meeting.

“On a voluntary basis, the agricultural community has put extensive effort into the management of nutrients and reducing runoff into waterways. This collaboration will help evaluate the impact of farmers’ conservation efforts on improving water quality,” said Ann Mills, USDA’s deputy under secretary for Natural Resources and Environment.

Mills said when hundreds of farms take action in one watershed, it can make a difference—it can help prevent an algae bloom downstream or lessen the need for water treatment plants to treat for nitrates.

The U.S. Geological Survey will now use Natural Resources Conservation Service data on conservation work to factor into its surface water quality models, which track how rivers receive and transport nutrients from natural and human sources to downstream reservoirs and estuaries. This information will help provide a more accurate picture of the conservation systems in the watershed that contribute to water quality improvement and will provide crucial information for voluntary nutrient management strategies and watershed planning.

“This agreement will allow NRCS and USGS to combine resource management capabilities with science, and will give us the information we need to prioritize the most effective conservation strategies so that we can improve the quality of streams throughout the Mississippi River Basin,” said Lori Caramanian, DOI deputy assistant secretary for Water and Science.

Working together, NRCS and USGS will develop conservation intensity data sets that reflect the value of conservation actions, but do not reveal private information about individual farms, ranches or forests. Protecting the trust relationship between NRCS and farmers and their private information protected by law is vital to the continued success of voluntary conservation on private lands.

“We know our farmers are doing great work to protect our natural resources. Our goal with this partnership is to be able to better recognize these achievements and provide conservation and water quality management communities with science-based information for improving water quality,” Mills said. “Farmers invest heavily in conservation systems to improve water quality, and we want to aid their decisions with the best science and information available.”

The conservation intensity products developed through the agreement will provide a uniform representation of conservation activities for use in water quality assessments at local, regional and national scales. Technical assistance providers will therefore have the assurance that they are using consistent and accurate information on conservation activities and a common platform for discussing conservation benefits.

Nutrient runnoff from many different sources, including urban areas and industry, impacts our nation’s waterways. By providing science-based information, NRCS and USGS can help farmers decrease nutrient runoff and improve water quality for their communities and downstream.
