Direct Download of L2A Analysis Ready Data from DLR Geoservice and EO-LAB
published on August 27, 2024
EnMAP Mission users now have an additional possibility to access L2A Analysis Ready Data (ARD) by registering with DLR’s Geoservice (https://geoservice.dlr.de/web/) or through the EO-LAB cloud. These services enable registered users to directly download L2A ARD data, which have already been processed using EnMAP’s Ground Segment processors and default processing parameters. This new access option provides immediate product downloads and facilitates the retrieval of large volumes of EnMAP data (see Data & Access section for a complete overview).
The default processing parameters of the L2A ARD are the following:
Product_Format = GeoTIFF+Metadata
Map Projection = UTM_Zone_of_Scene_Center
Image Resampling = Bilinear_Interpolation
Correction Type = Land_Mode
Cirrus Haze Removal = No
Band Interpolation = No
Terrain Correction = Automatic
Water Reflectance Product = Normalized_Rrs
Water Type = Turbid
Season = Automatic
Ozone column = Automatic
Some noteworthy differences of the L2A ARD with respect to the traditional archive access are:
the versions of the L2A ARD products may differ depending on their generation time. The processor changelog provides an overview of the software changes
The L2A ARD archive is still being completed and will continue to grow, including more EnMAP scenes in the coming months.
As always, the complete EnMAP Mission archive is available at the DLR multi-mission web portal EOWEB (https://eoweb.dlr.de/), where users can select the product level (L1B, L1C, L2A) for on-demand processing with the most up-to-date processor version. Additionally, users can choose more processing options (e.g., atmospheric correction over water) to obtain more precise results.
More information about Geoservice and availability of EnMAP L2A ARD products can be found in the Earth Observation Center news page (English link, German link).
