LPV
The objectives of the Land Product Validation subgroup are:
- To work with users to define uncertainty objectives
- To identify and support global test sites for both systematic and episodic measurements
(WGCV/Working Group on Information Systems and Services (WGISS) Test Facility [WTF])
- To identify opportunities for coordination and collaboration
- To develop consensus “best practice” protocols for data collection and description
- To develop procedures for validation, data exchange and management (with WGISS)
It was at a joint WGCV-ISPRS meeting at the University College London in May
of 1999 that the concept of an LPV subgroup was borne. The meeting reached the conclusion that the WGCV should initiate a Validation
subgroup within CEOS WGCV that would focus on the validation
of land products. A report from this meeting is provided here.
WGCV
Since its inception in 1984 the Working Group on Calibration and Validation has focused on ways in which the group can help ensure long-term confidence
in the accuracy and quality of Earth observation data and products
from satellites.
The CEOS WGCV was established as a result of the recognition that calibration
and validation activities should play a key role in all satellite Earth Observation
missions to ensure the clear and quantitative understanding of the data they
generate. The goal of the WGCV is to ensure long-term confidence in the accuracy
and quality of Earth observation data and products. The tasks of this group
are to provide:
- sensor-specific calibration and validation
- geophysical parameter and derived product validation
- a forum for calibration and validation information exchange, coordination, and
cooperative activities
- international exchange of technical information and documentation, joint experiments,
and the sharing of facilities, expertise, and resources

CEOS
The Committee on Earth Observation Satellites was established in 1984 and is recognized as the major international forum for
the coordination of Earth observation satellite programs and
for interaction of these programs with users of satellite data
worldwide. It's goal is to ensure that critical scientific
questions relating to Earth observation and global change are
covered and that satellite missions do not unnecessarily overlap
each other. The Committee is comprised of 44 members and associates (space agencies and organizations). Participating agencies make their best efforts
to implement CEOS recommendations, most of which come from
the come from the CEOS Working Groups.
