The EnMAP Ground Segment user services and products

Abstract

EnMAP (Environmental Mapping and Analysis Program) is a high-resolution imaging spectroscopy remote sensing mission dedicated to monitor and characterizing Earth's environment by providing accurate information on the state and evolution of terrestrial and aquatic ecosystems. EnMAP is equipped with a prism-based dual-spectrometer, which can make observations in the spectral range between 418.2 nm and 2445.5 nm with 224 bands and a high radiometric and spectral accuracy and stability. The EnMAP satellite was launched on 1 April 2022 and completed its commissioning phase in November 2022. From March 2023 EnMAP accepts user requests to acquire new acquisitions or download products from the mission archive. The EnMAP Ground Segment, under the responsibility of the German Aerospace Center (DLR), provides the services necessary to command the satellite and receive, archive and process the EnMAP data up to the three user product levels that can be ordered. These products are the radiometrically corrected at sensor top-of-the-atmosphere radiance product (L1B), the radiometrically corrected and orthorectified top-of-the-atmosphere radiance product (L1C) and the atmospherically corrected bottom-of-the-atmosphere reflectance product (L2A). The L2A processing supports options for Land processing, Water processing and a combine mode that automatically selects the correction based on pixel classification. In this contribution we offer an overview of the services provided by the EnMAP Ground Segment to the EnMAP data users: planning of new EnMAP acquisitions, access to archived data products and data processing. We cover in particular those aspects that, according to the user feedback, have been more challenging for the EnMAP users. We also provide an overview of the EnMAP products available and the different access or processing options that users can choose from.
