[Land cover and land use classification] [Water quality] [Water shortage]
The demand for a wall-to-wall system for monitoring spatial and temporal variations and
the follow-up of environmental trends, quality objectives and policy measures calls for a
new conceptual framework. The Observatory will address this by developing stable,
repetitive and quality-assured methods that integrate and optimise the use of earth
observation derived information, i.e. land use / land cover data with customized thematic,
spatial and temporal resolution, and ancillary geospatial data as input to catchment and
surface water modelling.
An integrated and innovative approach, based on different observation systems
available, ancillary data, statistical methods, catchment based source apportionment
models will contribute to improved monitoring programmes and to WFD reporting obligations.

Land cover and land use classification
| High to medium spatial resolution satellite data are
used, individually and/or in combination to derive the specific land cover / land use
products required as input to water quality and water shortage modeling. In the former
case the land cover classes forest, peatland and arable land are further refined, in the
latter case arable land is the main focus. |

Water quality
The refined land use products are used together with ancillary data as input to water
quality modeling, with focus on nutrient leakage to surface waters. The test sites are
situated in Germany (State of Thuringia), France (Adour-Garonne Basin) and Sweden (river
Dalälven basin).

Water shortage
| The test sites for water shortage are situated in Spain
(Ebro basin) and France (Adour-Garonne Basin). The product on consists of a set of GIS
compatible maps reporting on the water abstraction pressure by irrigation. |
