The Requirements Capabilities & Analysis for Earth Observations (RCA-EO) helps the USGS and other agencies take full advantage of U.S. and international Earth observation capabilities, and develop requirements-driven, prioritized investment decisions for new EO systems, products, and services.

USGS ECCOE staff support RCA-EO with high levels of expertise and years of knowledge about existing Earth observations systems, researching and identifying the capabilities of new systems, creating tools to help identify and visualize new sensors and the resulting data, and communicate research and results with the remote sensing community. 

ECCOE maintains and enhances the Earth Observation Requirements Evaluation System (EORES) for USGS and NOAA in support of understanding and assessing earth observing product value and user requirements, earth observing system capabilities.

Conducts independent technical characterizations and quality

assessments of a broad variety

of satellite, airborne and

in-situ earth observation systems

to support

USGS and its partners national land imaging science needs. 
Leverages resources

from Federal agencies for the characterization

of remote sensing

data and to share those results

across the remote sensing community. 
Provides long-term capability to

collect, maintain, and analyze

Earth observation requirements

and capabilities using relational databases,

user interfaces,

and analysis tools.

Facilitates the application

of multi- satellite and

in-situ data for characterization

and validation of satellite-derived land-related products.
