2016 Campaign Results (OTSC) statistics
Input from G4CAP
• pre-IR
• post-IR
• Campaign Results statistics
Why necessary:
• Need to know that imagery is used correctly (‘effective’
controls means doing the right things to produce a result)
• ‘efficient’ use of budget
• Need to prepare for CAP2020+ yes, but still live with
present CAP until then …
… only 10 MS
finalized the
requested 2016

2016 Campaign Results (OTSC) statistics
1. A lot of other statistics can be analysed if basis is complete…
2. Need to re-work to obtain clear and exactly the information
needed
3. Coordinate AGRI/JRC requests (no double work for MS)
4. Deadline on right moment post-campaign
5. New questions to understand better image use, and justify budget
request
6. This will be done for your campaign results statistics of 2017 (i.e.
Campaign Result module in G4CAP will be re-worked.)
7. Input to JRC from MS is welcome (on items 4, 5 …) by email (*)
giving suggestions …

2017 - Methods
Including Macedonia, excluding LPIS
No. of zones
VHR only
385 zones
(cf. 277; 2016)
VHR+HR
325 zones
(cf. 360; 2016)
Aerial+HR
48 zones
(cf. 38; 2016)
Total zones
758
(cf. 675; 2016)
More VHR zones; size same
Less VHR/HR; smaller
More aerial; smaller
In total more zones and
smaller => better targeting,
less HR due to S2
Area of zones

2016)
Total area to be
acquired
452,673 + 951 MKD

(cf. 488.834km2 ;

2017 - VHR satellite zones

(cf. 862.923 km2;

Trend reduction of no.

2017 - HR profiles and S2
• HR profile 2016 Campaign: 30% of HR volume
• 2017: 12% at end of iterations (end Dec 2016)
• 2017: 5% at G4CAP insertion (mid January Reg. deadline)
• S2 use 2016: approx. 11/32 MS Regions
• S2 use 2017: 16/32 MS Regions (i.e. use S2alert)
• S2alert in background at JRC, running daemon: i.e. we are
running on a separate server S2alert for all valid AW for all
ARs (VHR and HR); CC 0 % (opaque cloud) (but also
higher); results are checked before granting any re-task, and
to monitor S2 success rates.

2017 - other: atmospheric correction algorithm
Atmospheric Compensation (AComp), a capability to improve image quality and clarity in challenging atmospheric conditions by physically normalizing DNs to surface reflectance
Will be available as a choice in G4CAP next campaign - for interested MS also for 2017 contact us.
(*) - Atmospheric corrected imagery, more info at http://www.euspaceimaging.com/images/products/downloads/AComp_WP_ACOMP_WVGA.pdf,
also under documentation G4CAP

2017 - other: WV4 geometry bench
3 different viewing angles tested : 9˚,24˚, 36˚ ONA
2 software packages : PCI (RPC, Rigorous), ERDAS (RPC only)
21 ICP selected

Results:
• The WV4 PSH ortho imagery geometric accuracy meets
the requirement of corresponding to the VHR prime and backup
profiles defined in the VHR profile based Technical Specifications
• Moreover, the RMSEx, and RMSEy threshold of 1:5.000
scale imagery of 1.25m is fulfilled for all angles 9˚, 24˚,
36˚ONA when GCPs (≥3) are applied using RPC function
• From the results obtained, it is suggested however to
always use ≥ 4 GCPs
• Both software Erdas and PCI perform equally
• Some smaller issues being investigated
• Report will be published and made available.

• Lisbon -> G4CAP 2.1, now -> G4CAP 2.7
• most Lisbon feedback/requests have been
addressed and implemented
• Enhancements in S2 Alert module
• Reports now available for MSs / Contractors too
• Brand-new Feasibility management
• Users behavior is more controlled
• AWs pre-extension for MSs
• Introduction of ESPG codes for ortho-Profile AWs
• Automatic password change at 1st login
• Reports can now be stored and reloaded after
some time

Campaign 2018
• Further HR cut => S2, only HHR remains
• VHR2 => HHR …
• Rework G4CAP, pre-IR module; envelope given to MS 01/11
to avoid too much iteration.
• Thank you !!!
