Short Description

A representation of the GLC-SHARE Land Cover Database

Statement: Global Land Cover-SHARE (GLC-SHARE) provides access to an assembled product of global land cover.

Abstract: The basic concept adopted to develop this database is to integrate the best land cover data available, from local to global, into one single database using international standards; this task requires the harmonization among different layers and legends to create a consistent product. Here are criteria and steps for the harmonization:

absorb, overcome and minimize the thematic and spatio-temporal differences between individual databases;
create an efficient and practical mechanism to harmonize various datasets using the land cover elements;
use data fusion techniques to overcome some of the harmonization issues;

identify agreement/disagreement between a limited number of global dataset at pixel level;

create land cover database;
validate land cover database;
develop a fully automated “procedure” to update the database when new datasets may become available.
