ground truth data
=
training data
+
validation data
Mayaux’s plan on quality assessment
- use existing validation material
- prepare new validation material
validation material
 validation data
 validation data for distribution
Tateishi’s proposal
- distribute usable validation(or GT) data
widely
Global Land Cover Ground Truth database (GLCGT database)
The GLCGT database consists of regional land cover ground
truth (RLCGT) data. The geographical size of a RLCGT data is
flexible, from a city size to a continental size.

Potential input to GLCGT database
(a) from existing validation material/data of
other projects
(b) from new independent materials
(c) from training data of regional mapping in
GLC2000 project
Conclusion
