The newly finished ESA project MERIS Lakes included activity in Lake Victoria to show the potensial for monitoring this eutrophic African Lake. In this study an evaluation of how different processors perform in Lake Victoria. Lack of proper validation data makes it only possible to have a preliminary assessment of the performance of the product algal_2, suspended material and the signal depth, ...

SatStat – Satellite derived Statistical data on forest-change area – project is being developed under the framework of the European Space Agency (ESA) Announce of Opportunities (AO) for Portugal. The goals of this AO are the promotion of Earth Observation (EO) data usage and the contribution to the development of applications for Global Monitoring of Environment and Security (GMES). SatStat acc...

Following validation activities and corresponding improvements in processing algorithms over the first few years of the MERIS mission, the algal1 and algal2 products are now considered as sufficiently mature for use in applications in Belgian waters. The utility of this product has been enhanced by the development of a number of multitemporal products including single point time series, multite...

Determining the dominant optically active substances in water bodies via classification can improve the accuracy of bio-optical and water quality parameters estimated by remote sensing. This study provides four robust centroid sets from in situ remote sensing reflectance (Rrs (λ)) data presenting typical optical types obtained by plugging different similarity measures into fuzzy c-means (FCM) c...

Chlorophyll-a (chl-a) is a central water quality parameter that has been estimated through remote sensing bio-optical models. This work evaluated the performance of three well established reflectance based bio-optical algorithms to retrieve chl-a from in situ hyperspectral remote sensing reflectance datasets collected during three field campaigns in the Funil reservoir (Rio de Janeiro, Brazil)....

This study attempted to establish a broad regional phenological pattern for Northeast Asia using time-series data of the satellite measured index of terrestrial chlorophyll content (MERIS Terrestrial Chlorophyll Index) from 2003 to 2007. A suite of phenological variables were extracted from 4 integral seasons of time-series Medium Resolution Imaging Spectrometer (MERIS) Terrestrial Chlorophyll ...

The monitoring of water colour parameters can provide an important diagnostic tool for the assessment of aquatic ecosystem condition. Remote sensing has long been used to effectively monitor chlorophyll concentrations in open ocean systems; however, operational monitoring in coastal and estuarine areas has been limited because of the inherent complexities of coastal systems, and the coarse spec...

In the framework of Geoland, Infoterra France has mapped with MERIS the distribution of annual crops surfaces in Belgium, Poland and Russia (Rostov oblast). The maps provided are the acreages of main groups of crops per administrative or agricultural circumscriptions unit. The groups are winter, spring and root crops (sugar beet, potatoes). The method for mapping exploits the MERIS capability t...
