Wyoming Landscape Conservation Initiative data management and integration
Six Federal agencies, two State agencies, and two local entities formally support the Wyoming Landscape Conservation Initiative (WLCI) and work together on a landscape scale to manage fragile habitats and wildlife resources amidst growing energy development in southwest Wyoming. The U.S. Geological Survey (USGS) was tasked with implementing...Latysh, Natalie; Bristol, R. Sky
An analysis of spatial relation predicates in U.S. Geological Survey feature definitions
The Semantic Web uses a data model called a triple, which consists of a subject -predicate - object structure. When represented as triples, geospatial data require a spatial relation term to serve as the predicate linking two spatial features. This document summarizes the approaches and procedures used during the identification of spatial...Caro, Holly K.; Varanka, Dalia E.
A program for the conversion of The National Map data from proprietary format to resource description framework (RDF)
To expand data functionality and capabilities for users of The National Map of the U.S. Geological Survey, data sets for six watersheds and three urban areas were converted from the Best Practices vector data model formats to Semantic Web data formats. This report describes and documents the conver-sion process. The report begins with an...Bulen, Andrew; Carter, Jonathan J.; Varanka, Dalia E.
OpenStreetMap Collaborative Prototype, Phase 1
Phase One of the OpenStreetMap Collaborative Prototype (OSMCP) attempts to determine if the open source software developed for the OpenStreetMap (OSM, http://www.openstreetmap.org) can be used for data contributions and improvements that meet or exceed the requirements for integration into The National Map (http://www.nationalmap.gov)....Wolf, Eric B.; Matthews, Greg D.; McNinch, Kevin; Poore, Barbara S.
Ontology patterns for complex topographic feature yypes
Complex feature types are defined as integrated relations between basic features for a shared meaning or concept. The shared semantic concept is difficult to define in commonly used geographic information systems (GIS) and remote sensing technologies. The role of spatial relations between complex feature parts was recognized in early GIS...Varanka, Dalia E.
A 125 year history of topographic mapping and GIS in the U.S. Geological Survey 1884-2009, part 1: 1884-1980
On December 4–5, 1884, John Wesley Powell persuaded the U.S. Congress to authorize the U.S. Geological Survey (USGS) to begin systematic topographic mapping of the United States.Usery, E. Lynn; Varanka, Dalia; Finn, Michael P.
A 125 year history of topographic mapping and GIS in the U.S. Geological Survey 1884-2009, part 2: 1980-2009
The United States Geological Survey (USGS) entered the mainstream of developments in computer-assisted technology for mapping during the 1970s. The introduction by USGS of digital line graphs (DLGs), digital elevation models (DEMs), and land use data analysis (LUDA) nationwide land-cover data provided a base for the rapid expansion of the use of...Usery, E.

Gap Analysis - A Geographic Approach to Planning for Biological Diversity
The 2008 issue of the Gap Analysis Bulletin is the sixteenth in a series of annual publications produced by the Gap Analysis Program. Gap Analysis Bulletin No. 16 features 16 articles on various aspects of gap analysis methods and results. Topics addressed include applications, land cover, and aquatic gap analysis. The Bulletin also includes a...Maxwell, Jill; Gergely, Kevin; Aycrigg, Jocelyn; Davidson, Anne
The National Map product and services directory
As one of the cornerstones of the U.S. Geological Survey's (USGS) National Geospatial Program (NGP), The National Map is a collaborative effort among the USGS and other Federal, state, and local partners to improve and deliver topographic information for the Nation. It has many uses ranging from recreation to scientific analysis to emergency...Newell, Mark R.
GAP Analysis Bulletin Number 15
The Mission of the Gap Analysis Program (GAP) is to promote conservation by providing broad geographic information on biological diversity to resource managers, planners, and policy makers who can use the information to make informed decisions. As part of the National Biological Information Infrastructure (NBII) ?a collaborative program to...Maxwell, Jill; Gergely, Kevin; Aycrigg, Jocelyn; Canonico, Gabrielle; Davidson, Anne; Coffey, Nicole
Highly Pathogenic Avian Influenza Early Detection Data System (HEDDS)
HEDDS offers a unique opportunity for multiagency cooperation for data sharing and visualization.Worrest, Robert; Dein, F. Joshua
The Virginia Coastal Plain Hydrogeologic Framework
A refined descriptive hydrogeologic framework of the Coastal Plain of eastern Virginia provides a new perspective on the regional ground-water system by incorporating recent understanding gained by discovery of the Chesapeake Bay impact crater and determination of other geological relations. The seaward-thickening wedge of extensive, eastward-...McFarland, Randolph E.; Scott, Bruce T.
As part of The National Map transition to cloud hosting, several of the National Map NAIP Orthoimagery Services will be provided under new URLs.
Calling all Earth Science professors conducting research or teaching geologic mapping. The USGS EDMAP Program is accepting funding proposals focusing on geologic mapping to support upper-level undergraduate and graduate students at their colleges or universities.
