To foster quantitative validation of higher-level global land products derived from remote sensing data and to relay results so they are relevant to users.

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
- 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
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.
The role of the co-chairs for each focus area will be to engage the appropriate research and operational communities and to coordinate global validation activities. This role involves 3 main components:
1) Development of protocols for the validation of satellite-derived products and defining guidelines for reporting results,
2) Coordination and Implementation of global validation activities, and
3) Provide the interface between the community, CEOS and other international structures.
