• ground truth data
• training data
• validation data

• Mayauxs plan on quality assessment
• - use existing validation material
• prepare new validation material
• validation material
• ? validation data
• ? validation data for
  distribution
• Tateishis 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.

--- metadata of RLCGT data (text) --- GT
land cover code data (raster) --- GT
site code data (raster) --- description
of GT sites (text) --- optional data
(text, raster, or any)

• metadata of RLCGT data
•  
• - RLCGT code (this code is assigned by the
  coordinator of the GLCGT database project)
• - the organization or project which produced this
  RLCGT data
• - representative person which produced this RLCGT
  data (name, affiliation)
• - contact person for this RLCGT data (name,
  affiliation, postal address or fax or email)
• - date of the production of this RLCGT data
• - latitude of the north edge of this region

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
