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 domain
USGS 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
6
Sample USGS data available over
the Web
Data 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
7
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

Data Sharing Needs for Global
Science
Land 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
19
Data Sharing Needs for Global
Science
Energy 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?
20
Data Sharing Needs for Global
Science
Hazards – 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
21
Data Sharing Needs for Global
Science
Data 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
22
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
23
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
24
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
