ABSTRACT:
Geoland2 project is part of the GMES EU-lead initiative and intend to prepare, validate and demonstrate pre-operational service
chains and products of the Land Monitoring Core Service (LMCS), and to propose its specific functional organization. The
architecture of geoland2 is made of 3 Core Mapping Services (CMS) providing “basic” land products, and 7 Core Information
Services (CIS) which are thematic elements using the CMS products to generate more “elaborated” information addressing specific
European policies. One CMS, called BioPar, is dedicated to the production in near real-time and off-line mode of biophysical
variables describing the continental vegetation state, the radiation budget at the surface, and the water cycle.
We focus here on the following product lines: the Leaf Area Index, the Fraction of green Vegetation Cover, the Fraction of PAR
absorbed by the vegetation, the NDVI, the surface albedo, and the Soil Water Index. Until 2012, the objective is to define, develop,
validate, and run 2 versions of the processing lines. For each version, test data sets are generated: they are dedicated to the
scientific validation performed by independent team, and to the product utility assessment carried out by the CIS users.
The talk will describe the organization setup to build the system, including the interfaces upstream with the team in charge of the
algorithm definition, and downstream with the production centre which will perform the operation and dissemination. The
emphasis will be put on the qualification procedure applied at each step of the development process. The test data sets, available
during the
second quarter of 2010, will be presented. Furthermore, we will show the main results of the validation procedure which relies on
comparison with ground measurements, and on inter-comparison with similar EO-based products, and the first feedback about the
utility of these products for the users’ applications.
1. THE GEOLAND2 PROJECT
1.1 Structure
The FP7 GEOLAND2 project is part of the GMES EU-lead
initiative and intend to prepare, validate and demonstrate pre-
operational service chains and products of the Land Monitoring
Core Service (LMCS), and to propose its specific functional
organization. The GEOLAND2 consortium includes 50
European partners : private companies, public institutions,
service providers, research laboratories, etc .
GEOLAND2 is made of 3 Core Mapping Services (CMS)
providing “basic” land products, and 7 Core Information
Services (CIS) which are thematic elements using the CMS
products to generate more “elaborated” information addressing
specific European policies (Figure 1). The 3 CMS deliver
global or local maps at various temporal scales in the following
areas of interest:
• Euroland : Periodic land cover change and urban
atlas
• BioPar : near real-time and off-line biophysical
parameters
• SATChMo : Area frame sampling for seasonal
monitoring and global land cover change
The 7 Core Information Services (CIS) use the CMS products
to provide high level analysis maps on the following topics :
• Land Carbon
• Global Crop Monitoring
• Natural Resource Monitoring in Africa (NARMA)
• Agricultural Environment
• Forest
• Water
• Spatial Planning.
