Core Science Systems
The U.S. Geological Survey (USGS) Core Science Systems (CSS) Mission Area builds on the core strengths of the USGS in characterizing and understanding complex Earth and biological systems through research, modeling, mapping, and the production of high-quality data. CSS delivers natural science information to the Nation in support of smart decisionmaking.
National Geospatial Program
The National Geospatial Program is the Federal civilian mapping agency and provides the digital geospatial foundation for the Nation. It engages partners and communities of use to collaboratively produce consistent and accurate topographic map data.Learn More
Core Science Analytics, Synthesis, and Libraries
The USGS Science Data Catalog, supported by CSAS&L, provides seamless access to USGS research and monitoring data from across the nation. Users have the ability to search, browse, or use a map-based interface to discover data.Learn More
No one has a crystal ball to foresee what will happen during the 2018 hurricane season that begins June 1, but NOAA forecasters say there’s a 75 percent chance this hurricane season will be at least as busy as a normal year, or busier.
New research has revealed significant changes to Alaska’s landscape in recent decades
The National Map provides a new Simple Notification Service and has new URLs for some of its thematic cartographic map services.
Modeling and simulation of emergent behavior in transportation infrastructure restoration
The objective of this chapter is to create a methodology to model the emergent behavior during a disruption in the transportation system and that calculates economic losses due to such a disruption, and to understand how an extreme event affects the road transportation network. The chapter discusses a system dynamics approach which is used to...Ojha, Akhilesh; Corns, Steven; Shoberg, Thomas G.; Qin, Ruwen; Long, Suzanna K.
An open source high-performance solution to extract surface water drainage networks from diverse terrain conditions
This paper describes a workflow for automating the extraction of elevation-derived stream lines using open source tools with parallel computing support and testing the effectiveness of procedures in various terrain conditions within the conterminous United States. Drainage networks are extracted from the US Geological Survey 1/3 arc-second 3D...Stanislawski, Larry V.; Survila, Kornelijus; Wendel, Jeffrey; Liu, Yan; Buttenfield, Barbara P.
A linked GeoData map for enabling information access
OverviewThe Geospatial Semantic Web (GSW) is an emerging technology that uses the Internet for more effective knowledge engineering and information extraction. Among the aims of the GSW are to structure the semantic specifications of data to reduce ambiguity and to link those data more efficiently. The data are stored as triples, the basic data...Powell, Logan J.; Varanka, Dalia E.
