New search and results interface
A new search and result interface has been deployed on satellittdata.no. We present a short video to highlight the new available functionalities.

NBS
This interface is focusing on the possibilities opened by accessing data through OPeNDAP. OPeNDAP is a protocol that allows data streaming, in the sense that products are not required to be downloaded, but can be accessed without disk access. This implies that products are converted to NetCDF (SAFE is still available) which enables NBS to offer operations like subsetting and transformation (e.g. reformatting and reprojecting) more or less on the fly. Furthermore, it allows combination of products into spatial or temporal stacks of products for further processing.
Currently only Sentinel-2 is provided in this form, and NBS is working on Sentinel-1 access. Data are slightly postprocessed in NetCDF. All bands in Sentinel-2 are e.g. interpolated to the highest resolution, but using a lossless interpolation that allows users to access the original information.
ColHub/DHUS
This interface is the same as offered by e.g. SciHub. All data synchronised to the National Ground Segment are available as SAFE files in this interface.
