USGS Science
Data Integration and Beyond The USGS will use its information resources to
create a more integrated and accessible environment for its vast resources of past and future data. It will invest in cyberinfrastructure, nurture and cultivate programs in natural-science informatics, and participate in efforts to build a global integrated science and computing platform.

USGS Data – All USGS data are in the public domainUSGS has vast data holdings, currently organized by
Disciplines (5) and Programs (29)
Disciplines
Geography, Geology, Water, Biology, Geospatial Information Office
Currently reorganizing along Science Strategy research priorities; data organization will follow Strategy and will be integrated across research priorities
Council on Data Integration now an active body in USGS to force integration
7
Sample USGS data available over the WebData sites shown are only a sampling from the
USGS Disciplines
Additional data also available
Most USGS data are for the USA
For global science, data are needed for the rest of the world
Most logical approach is data sharing with other countries
8
Geography – Topographic Data
Raster– nationwide, multiple resolution, multi-temporal
Elevation – 1, 1/3, and 1/9 arcsec (lidar source)
Landcover – LUDA 1970s, NLCD 1992, 2000
Orthoimages – 1 m resolution, 0.33 m resolution for the 133 HSIP urban areas
Large data volumes; example, 0.33 m resolution orthographic images for city of Atlanta is 800 GB of data
Repeat cycle of 3 years
New effort by Microsoft to obtain 0.15 m resolution for all of USA

Geography – Topographic Data
Vector – nationwide, multiple resolution, multi-temporal
National Hydrography Dataset – medium resolution (1:100,000-scale source), high resolution (1:24,000-scale source), and some local
(1:4,800-scale and larger sources)
National Transportation Dataset – from Census
currently negotiating with Open Street Map
National Boundaries Dataset
National Structures Dataset
Geographic Names Information System

Data Sharing Needs for Global ScienceLand cover change – USGS has data at 30 m
resolution for the U.S.A., repetitive coverage with plans for 5 year update cycle
For study of global climate change, we need land cover change at 30 m resolution for the rest of the world. Can we start with a land cover data exchange with China?
For global climate change we need Essential Climate Variables (ECVs); requires global data
20
Data Sharing Needs for Global ScienceEnergy and minerals – USGS has U.S.A.
coverage
Can we exchange data to get world coverage?
Begin with China?
Ecosystems – USGS has data for U.S.A.
Exchange to get data for the rest of the world?
Begin with China?
21
Data Sharing Needs for Global ScienceHazards – USGS has U.S.A. data
Need data for the world to model global hazards, risk, and resilience
Water – U.S.A. data available; exchange for global coverage
Environment effects on wildlife and human health – USGS has some data for USA, but need data for the world for science study
22
Data Sharing Needs for Global ScienceData Integration
Invest in cyberinfrastructure, nurture and cultivate programs in natural-science informatics, and participate in efforts to build a global integrated science and computing platform
Requires global data – only possible through data sharing
23
Technical problems
Compatible data models
Resolution, accuracy issues
Attribution issues – need ontology that allows matching across data schema
Data sharing is more than making data available for download over the Web
Requires standards
USGS data meets Federal Geographic Data Committee and Open Geospatial Consortium standards for metadata and packaging
24
Standards issues
Data sharing is more than making data available for download over the Web
Requires standards
USGS data meets Federal Geographic Data Committee and Open Geospatial Consortium standards for metadata and packaging
Global standards needed to facilitate data sharing
25
Proposal
Project to explore sharing geospatial data for science applications through standards
Begin with existing standards and conduct pilot studies with specific datasets common to China and USA
Initial data for land cover change is a good starting point
