○ SEC_008b - Support reconstruction missions after conflicts
A summary of the needs from the LMCS as well as other land services is described hereafter
as relevant to Sentinel-2 type of sensors:
○ Acquisition tasking needs
Security services generally require time-sampled data for monitoring purposes, but not
necessarily all data systematically generated. Almost all services require a predefined
satellite tasking, excluding ‘‘terrain analysis and mobility assessment’’ and ‘’postconflict
damage assessment’’.
Hence, an approach similar to the coverage datasets introduced in the Land service
review is considered appropriate.
○ Products and quality needs
The same requirements as for the Emergency Services are identified. In this case
most of services requires explicitly ortho-rectified data while geolocation accuracy is
variable and sometimes is still TBD, but actually very stringent. Furthermore quite
important is the requirement on the cloud coverage which generally has to be less than
25%.
In addition, the following drivers to the mission operations are highlighted:
○ Systematic pre-defined long term satellite tasking capability;
○ Capability to support generation of coverage data sets;
○ Access to systematic medium-term data through subscription;
○ Product quality stability monitoring, accurate radiometric calibration and traceability;
○ On-line access to historical products;
○ Mission data reprocessing;
○ Mapping frequency variable wrt. the service
