The EO4SD Lab provides a range of thematic processing services (Table 1) and supporting interactive tools and applications (Table 2). Service Portfolio documents (pdf) are currently being prepared to provide details of each service and how it can be used. The EO4SD Lab User Manual provides detailed guidance on how to use the portal including accessing and running each service and tool. Table 3 provides an overview of the accessible EO data.

The output GeoTiff is displayed in geobrowser with the possibility to access product metadata and download original dataset to be used in further processing. The service supports a variety of optical and SAR detected products from the following missions: Pleiades 1A/1B, SPOT- 6/-7, Sentinel-2A/2B L1C, Landsat-8 L1, UK-DMC 2 L1T, Kompsat-2/-3 L1G, Kompsat-5 L1D, Kanopus-V, Resurs-P, Terrasar-X L1B, Sentinel-1A/1B GRD, ALOS-2 L15, Radarsat-2 SGS SAR, Rapideye L3A, VRSS1 L2B, GF-2 L2A, Sentinel-3 (EFR, ERR and RBT). Note that the current verison of the EO4SD Lab provides access to Sentinel-1, Sentinel-2, Sentinel-3 and Landsat-8 data. In case of Sentinel-1 IW data the resolution is 20mx20m in order to increase the number of looks and reduce image size. A short service guide is provided here.
Note that this service supports additional EO input datasets beyond those available in the current version of EO4SD Lab .
