Spatial Relation Predicates in Topographic Feature Semantics
Topographic data are designed and widely used for base maps of diverse applications, yet the power of these information sources largely relies on the interpretive skills of map readers and relational database expert users once the data are in map or geographic information system (GIS) form. Advances in geospatial semantic technology offer data...Varanka, Dalia E.; Caro, Holly K.
Rejuvenating Pre-GPS era geophysical surveys using The National Map
Old geophysical surveys [pre–Global Positioning System (GPS)] stand as valuable, largely untapped sources of scientific data. If data from these surveys were in a format that had reasonable accuracy, availability, and ease of access, they could be more widely used. In this paper, a pre-GPS survey is integrated into a modern geographic database, in...Finn, Michael P.; Shoberg, Thomas G.; Stoddard, Paul
Lidar base specification
In late 2009, a $14.3 million allocation from the “American Recovery and Reinvestment Act” for new light detection and ranging (lidar) elevation data prompted the U.S. Geological Survey (USGS) National Geospatial Program (NGP) to develop a common base specification for all lidar data acquired for The National Map. Released as a draft in 2010 and...Heidemann, Hans Karl
Digital Mapping Techniques '10-Workshop Proceedings, Sacramento, California, May 16-19, 2010
The Digital Mapping Techniques '10 (DMT'10) workshop was attended by 110 technical experts from 40 agencies, universities, and private companies, including representatives from 19 State geological surveys (see Appendix A). This workshop, hosted by the California Geological Survey, May 16-19, 2010, in Sacramento, California, was similar in nature...Soller, David R.; Soller, David R.
Introduction to geospatial semantics and technology workshop handbook
The workshop is a tutorial on introductory geospatial semantics with hands-on exercises using standard Web browsers. The workshop is divided into two sections, general semantics on the Web and specific examples of geospatial semantics using data from The National Map of the U.S. Geological Survey and the Open Ontology Repository. The general...Varanka, Dalia E.

User's guide for mapIMG 3--Map image re-projection software package
Version 0.0 (1995), Dan Steinwand, U.S. Geological Survey (USGS)/Earth Resources Observation Systems (EROS) Data Center (EDC)--Version 0.0 was a command line version for UNIX that required four arguments: the input metadata, the output metadata, the input data file, and the output destination path. Version 1.0 (2003), Stephen Posch and Michael P....Finn, Michael P.; Mattli, David M.
The use of U.S. Geological Survey digital geospatial data products for science research
The development of geographic information system (GIS) transformed the practice of geographic science research. The availability of low-cost, reliable data by the U.S. Geological Survey (USGS) supported the advance of GIS in the early stages of the transition to digital technology. To estimate the extent of the scientific use of USGS digital...Varanka, Dalia E.; Deering, Carol; Caro, Holly
Remote sensing of soil moisture using airborne hyperspectral data
Landscape assessment of soil moisture is critical to understanding the hydrological cycle at the regional scale and in broad-scale studies of biophysical processes affected by global climate changes in temperature and precipitation. Traditional efforts to measure soil moisture have been principally restricted to in situ measurements, so...Finn, Michael P.; Lewis, Mark (David); Bosch, David D.; Giraldo, Mario; Yamamoto, Kristina H.; Sullivan, Dana G.; Kincaid, Russell; Luna, Ronaldo; Allam, Gopala Krishna; Kvien, Craig; Williams, Michael S.
Topographic mapping data semantics through data conversion and enhancement: Chapter 7
This paper presents research on the semantics of topographic data for triples and ontologies to blend the capabilities of the Semantic Web and The National Map of the U.S. Geological Survey. Automated conversion of relational topographic data of several geographic sample areas to the triple data model standard resulted in relatively poor semantic...Edited by Ashish, Naveen; Sheth, Amit P.; Varanka, Dalia; Carter, Jonathan; Usery, E.

US Topo - a new national map deries
In the second half of the 20th century, the foundation of the U.S. Geological Survey's national map series was the handcrafted 7.5-minute topographic map. Times change, budgets get squeezed and currency expectations become ever more challenging. The USGS's Larry Moore, who oversees data production operations at two National Geospatial Technical...Moore, Laurence R.
Digital Mapping Techniques '09-Workshop Proceedings, Morgantown, West Virginia, May 10-13, 2009
The Digital Mapping Techniques '09 (DMT'09) workshop was attended by 90 technical experts from 42 agencies, universities, and private companies, including representatives from 24 State geological surveys. This workshop, the thirteenth in the annual series, was hosted by the West Virginia Geological and Economic Survey, May 10-13, 2009, on the West...Soller, David R.
For more than two decades, researchers, geologists, and investors had no idea they were standing above tremendous wealth. Thousands of feet deep beneath the surface of western Michigan, a potential multibillion-dollar potash deposit was discovered. Potash—a mineral salt containing high levels of potassium—is an ingredient in fertilizer essential for growing crops.

The USGS announces the sunset of National Map High Resolution Orthoimagery Data and Service
The U.S. Geological Survey is pleased to announce the selection of Dr. Christian Zimmerman as the new director of their Alaska Science Center in Anchorage, Alaska. Zimmerman succeeds Dr. Mark Shasby who held the position for the past six years.
The topic, officially, was water. But during a scientific conference in Butte, Montana, in 2013, earthquake expert Michael Stickney glimpsed something unexpected in a three-dimensional lidar image of the Bitterroot Valley in nearby Missoula.
USGS has many partnerships, both foreign and domestic, that enhance our science capabilities, provide needed support to others, and expand our ability to serve the global community. One little-known partnership that serves both foreign and domestic needs is the USGS science support to the U.S. Department of Defense (DOD) - U.S. Northern Command (USNORTHCOM).
