The Globcover Initiative

Abstract

The Globcover initiative comprises the development and demonstration of a service that in first instance produces a Global land cover map for year 2005/2006. Globcover uses MERIS fine resolution (300m) mode data acquired between mid 2005 and mid 2006 and, for maximum user benefit, the thematic legend is compatible with the UN Land Cover Classification System (LCCS). This new product updates and complements the other existing comparable global products, such as the global land cover map at 1km resolution for the year 2000 (GLC2000) produced by JRC. It is expected to improve such previous global product, in particular because of the finer spatial resolution. The Globcover project is an initiative of ESA in cooperation with an international network of partner including EEA, FAO, GOFC-GOLD, IGBP, JRC and UNEP. Building on the success of the GLC-2000 project (Global Land Cover map for the year 2000) coordinated by the JRC, ESA decided to launch the GLOBCOVER initiative in the framework of its Data User Element (DUE). The GLOBCOVER product is intended for European and international users, such as but not limited to, services of the European Commission, the European Environmental Agency (EEA), UNEP, FAO, GOFC-GOLD and IGBP. By example, GOFC-GOLD, which is an international program to monitor forest cover and land dynamics globally, push strongly to improve global land cover assessment (GEOSS, GCOS IP, IGOL …) because existing land data though are not yet fully satisfying. IGBP has an interest in GLOBCOVER as a data source in the ongoing studies of land-cover and land-use dynamics particularly to improve our understanding of the variation of the nature-society dynamics of land management, thereby facilitating the regional and global modelling that is vital for climate impact and sustainability research. The GLOBCOVER concept of global land cover determination at fine spatial resolution with repeatability will contribute significantly to the body of data sources required for this effort. The MERIS 300m Full resolution Full Swath (FRS) products are the main data source of the GLOBCOVER project. ESA made continuous effort to ensure the acquisitions and the provision of the data for the period from 1 In order to deliver the full dataset of data, the MERIS FRS acquisition capacities had to be highly increased. This mainly results from a better strategy of acquisition between ASAR and MERIS instruments outside of Artemis Mask. Due to the low data coverage in some parts of the world (East of Amazonian …
