The Data Access Portal in general include two major entry points: the EnMAP Instrument Planning Portal and the EOWEB® GeoPortal.
On the EnMAP Instrument Planning Portal users can register, submit proposals, and plan and request future orders. The EOWEB® GeoPortal contains the full EnMAP Data archive. Users can access EnMAP data using two different options:
- Users can request acquisitions through the EnMAP Instrument Planning Portal. The portal includes the Proposal Portal for proposal submission by all scientific users responding to an Announcement of Opportunity (AO) and the Observation Request Portal providing planning support of observation requests and submission of future orders.
- Users can search and order data in different processing levels from the German Satellite Data Archive (D-SDA) through the EOWEB® GeoPortal.
More information on using the EnMAP Data Access Portal is available in the user manual and in short video screencasts linked in the menu belowon the left.
Product Levels
The following EnMAP data products are available to the user community: Product Level 1B, 1C, and 2A. Please, note that the raw data and the subsequent Level 0 products are not available to the user community. This section provides a short definition of these products, a more detailed description can be found in Guanter et al. (2015) and Kaufmann et al. (2016).
The systematic/radiometric correction processor converts raw image pixels values to at-sensor radiance physical values
The geometric correction processor orthorectifies images using different methods and performs the resampling of the image (with and without automatically extracted GCPs)
The atmospheric correction processor produces reflectance values for land and water areas and generates several quality masks.
The output processor generates the final image product and masks as well as the metadata and history files.
Processing and delivery of Level 1B, Level 1C and Level 2A products are to be conducted within a maximum of 6 days after completion of the corresponding downlink. The user can choose the image format (BSQ, BIL BIP, JPEG2000 or GeoTIFF). The metadata is always in Extensible Markup Language (XML) format.
