Detailed Record Sheet

ISSUE RID SECTION PROBLEM DESCRIPTION CHANGE

1.1 D5.1 3.1 The configuration parameters need to be fully accessible to the main administrator. For the general user we need to define during the prototyping how to constrain the parameter list to the essential ones.

Rephrased the configuration utility description.

These advanced parameters can define things that don't normally change during the system operation (e.g. hostnames or IP addresses), but even so, they can be changed directly in the database.

If having these read-only parameters is not desired, they can be marked as read-write (i.e. not advanced) in the database, which will allow the configuration utility users to edit them.

1.1 D5.2 3.1 Please include the main parameters for the atmospheric correction e.g. aerosol model in the standard configuration list.

Please include parameters for configuration of the archiving and retention policies for final and intermediate products.

Aerosol model choice was added in table Table 4-1.

Parameters for archival and retention times were added in table Table 4-1.

1.1 D5.3 3.1 Please include the accuracy measures by tile and globally for the AOI in table 3-2 as they might be different.

The granularity of the accuracy measures has been updated in Table 4-2.

1.1 D5.4 3.1.2 Please clarify if the L1c and L1T product downloaders will be fully automatic, once parameterized.

Text clarified in Erreur ! Source du renvoi introuvable.

1.1 D5.5 Please provide a reference to SLURM and add it in the abbreviation list

Reference provided in Erreur ! Source du renvoi introuvable. and added in the abbreviation list

1.1 D5.6 3.1.3 Please include a general introduction/definition of the purpose of the persistence layer.

General description added in Erreur ! Source du renvoi introuvable.

1.1 D5.7 3.2 Include a section on the approach and implementation of the reprocessing mode of the system. Update figure 3.7 accordingly. Clarify if and what impact reprocessing has on ongoing standard processing.

Figure 4-7 modified and paragraph Handling processing errors added in section Erreur ! Source du renvoi introuvable.

1.1 D5.8 3.3 Please ensure that users will have, if required, clearly separate and protected user workspaces

Text modified in section Erreur ! Source du renvoi introuvable.

1.1 D5.9 3.4 Please mention the additional options of L1T download including an ESA and Nasa specific access. As no details are available just list them as possible options to be considered.

Text modified in section 3.4.2

1.1 D5.10 3.4.5 Please clarify the requirements and limitations of the Tool Adaptor to successfully integrating the S2-Agri processors.

Full support shall be given to the Sentinel toolbox team to integrate the processors in the toolbox including the preparation of templates and STA module defintions.

Added clarification notes. Would there be more information needed?

1.1 D5.11 4.2 Please define the source and eventual interfaces to all required inputs e.g. vector file of S2 and L8 tiles extent, S2 orbits, DEM.

If the availability of any of the inputs are unclear please clearly highlight this and propose mitigation measures.

Text and table added in section 3.4.7

1.1 D5.12 4.2 Please specify the definition of the coefficients for the bidirectional model.

Please clarify the impact on the composite due to the lack of observation angles for L8

TBD

1.1 D5.13 General Include in main DDF a general system overview as done in the ATD.

Section 2 added

AI_3 Find a solution to run the batch mode with L1 data (CS)

Text added in Annex. 1: the impact on the system is to important and the solution not practicable from an user point of view.

AI_6 Update the DDF to reflect the fact that the Sen2Core masks are not incompatible with the composite processor (CS)

Text added in section 4.4.6

AI_8 Implement in the system a second option to by-pass the segmentation (CS)

Define new segmentation parameters (UCL)

Text updated in section 5.2.26.2 and option added on table 4-1

Still to be done by UCL

AI_9 Correct the articulation of the in-situ and no in-situ modes in a way that spatial consistency is ensured at the site-level (UCL-CESBIO)

AI_10 (Crop Mask): Add an option to allow delivering the product as a global raster file over an Area Of Interest (CS). Develop an adequate method to do such mosaicking (UCL-CESBIO)

First description of this module is added in the section 4.2.27

Further discussions are needed

AI_11 (Crop Type) Add the possibility to run the prepare samples module before the production of the 1st map (either in the system or outside) (CESBIO-CS)

Text updated in section 4.2.15.1 and section 3.1.1.4.2

AI_12 (Crop Type): Clarify the RF and SVM parameters in the DDF (+/- RID 5.17) (CESBIO)

AI_13 (Vgt status): Clarify the model parameters in the DDF (parameter list, values and ranges) (+/- RID 5.15) (CESBIO)

AI_17 Test the Google API as a possible solution for L8 access in the system (CS)
