EnMAP User Interface - An Overview of EnMAP ground segment services

Abstract

EnMAP (Environmental Mapping and Analysis Program) is a future German hyperspectral satellite mission providing high quality hyperspectral image data on a timely and frequent basis. Main objective is to investigate a wide range of ecosystem parameters encompassing agriculture, forestry, soil and geological environments, coastal zones and inland waters. The EnMAP Ground Segment will be realized and operated by the German Aerospace Center (DLR) covering all aspects relevant to assure successful mission operations. This comprises controlling and commanding the satellite using multi-mission infrastructures as well as data reception, hyperspectral data processing including calibration, data archiving, data dissemination, and providing web-interfaces to the international user community. From the users´ point of view there are two major scenarios of particular interest. First the handling of image acquisitions based on user requests and second the generation of standardized products based on acquisitions or archive orders by users. This paper provides details on the concepts, design and functionalities of the EnMAP user interface, which consists of two online portals interfaced with several subsystems of the EnMAP Ground Segment: First the EnMAP Portal (www.enmap.org) provides general EnMAP mission information. It is the central entry point for all users interested to learn about the EnMAP mission, its objectives, status, and results. Second the EnMAP Data Access Portal links to a set of functions for registered users that will support the international EnMAP user community. This portal includes amongst others a proposal portal allowing submission of proposal for all users responding to a Data Announcement of Opportunity (AO). The proposals and the associated results will be presented by an interactive map supporting the establishment of a worldwide user network and guarantee the highest transparency of the proposal process. Observation requests are issued to order EnMAP data takes and provides all information required for scheduling data takes such as location and extension of the observation area, acquisition time frame, sensor look angle and required data products. Additionally, the platform informs about the conditions and requirements for the EnMAP data access and the ongoing scientific programs and activities. The catalogue browse and order service (EOWEB portal) allows browsing and ordering of EnMAP data products that have previously been acquired, processed, and archived in the product library. The operational services offered through the EnMAP (Data Access) Portal will be complemented by a service team, EnMAP Application Support, offering expert advice on the exploitation of EnMAP data.
