the GTCAP/CAPISA image acquistion team

Baveno, IT, 23-25/05/2016

Presentation Outline

• Satellite data management 2016 - what happened since Thessaloniki ?

• Campaign 2016 in a nutshell - status

• VHR/HR Specs; today & what will happen?

• G4CAP / S2 / Copernicus

• Image return / Miscellaneous

What happened since Thessaloniki (1)

Steps taken to reduce the requests for satellite data provision for Campaign 2016:

1. Pre-Image Request (pre-IR) (1) - we call it the “pre-Thessaloniki status”, as

of 24/11/2015

2. Pre-IR (2) - we call it the “post-Thessaloniki status”, as of 31/12/2015

3. Final IR after final insertion in G4CAP IR module (27/01/2016) and frozen for

feasibility with Image Providers, and which are the volumes we are

programming now.

• Close follow up by JRC and DG AGRI and interface with MS

Administrations allowed reduction in accordance with efficiency criteria

set for 2016 (mainly reduction in accordance to cost/OTSC area)

• So budget demand was reduced from 9.65M€ to 8.44M€ to 8.18M€ for

the VHR and HR imagery (does not include LPIS and some OH)

• MS should strictly follow up “efficient image use” during 2016

campaign

• MS should elaborate similar/other indicators for 2017 Campaign

i.e. changing efficiency a little on a big budget is worth a lot …

JRC can help …



• So, repeating from Thessaloniki: MS + EC need to ensure a method that

demonstrates efficient and effective controls at a cost efficient budget

• No change in budget planned for next campaign (2017)

• Short term:

Efficient sampling

Right size of control zone

No. of acquisition windows needed

Type/mode, profile (PSH, MSP; ORTHO)

Use new sensors S1, S2

Combine with alternatives: Recover LPIS

imagery, more aerial ? traditional OTSC ?, etc.

LPIS QA status

LPIS

• Similar approach as 2015 campaign, with the use of 40cm pixel size

when possible

• there is no upfront sensor selection, all three sensors WV2/WV3/GE1

can be considered by the image provider

If WV2 acquires (=> 50 cm pixel size), delivery of 225 km²

If GE1 or WV3 acquire (=> 40 cm pixel size), delivery of 169 km², i.e.

the single shot area of WV3 with smallest swath (13km)

VHR/HR Specs; Campaign 2016

• New specs out since Thessaloniki, and updated to their final version

after input from MS and contractors – these are valid this campaign

• https://g4cap.jrc.ec.europa.eu/G4CAP/ (under documentations tab)

• What has improved:

documents are more consistent

G4CAP better explained / links

pre-IR parameters better explained

issues on windows definition

e.g. even if you agree to VHR backup you may extend window

VHR feasibility (removal of +/- 3 days in most cases)

HR feasibility improved

new profiles inserted, and LPIS profile better explained

ortho image return chapters revised

better description of sensors in annex

VHR/HR Specs; Campaign 2017 … tbd (1)

New revisions open for discussion for 2017 Campaign

VHR/VHRplus

• Clear justification to use VHR2 window

HR/HHR

• Discontinue HR ? - extensive use of S2A and S2B (launch during 2016)

• Clear justification for request of autumn / winter / HR-1; revert to S2

use for especially these windows

• Continue use of HHR (1.5/6m SPOT 6/7) for the other windows; revert

to use of S2 also here where possible

• HHR window length 6-8 weeks like VHR

• MS need to use earliest start date / latest start date / dead period

better. Maybe introduce a

latest close date =>

will allow a ‘real’ feasibility

also for HHR

VHR/HR Specs; Campaign 2017 … tbd (2)

HR/HHR (cont.)

• Sentinel 2A repeat cycle at equator 10 days => 35 passes/year; this

means >70 passes at 60 deg. lat. due to overlapping swaths from

adjacent orbits …

• in “mid-EU” we have 40-50 passes / year => approx. every week (with

one satellite) => approx. 6 passes per window

• with S2B the double …

Suggestion to use all cloud free pixels from S2 together with 1VHR plus 1

or 2 HHR

• 2016 tests

• 2017 operational

• Needs assessment by MS

• Needs validation by EC

Image return status

Both SOURCE and ORTHO image return of both CwRS and LPIS imagery

goes to JRC via the image providers.

The MS Administrations and their contractors need to collaborate with the

image providers in the return of their ORTHO corrected imagery

• See details in the VHR/HR Specs

Some problems for 2015 return:

FR-LPIS, LT-LPIS, NL-LPIS

some issues to solve)

Miscellaneous

General - communication within G4CAP needs to be fast, efficient, and

according to specificatioons !!!

• Need fast reaction from you and your contractors on e.g. IDQA, on ’proposed’

imagery, etc. You are receiving autoimatic email reminders.

• Always communicate window changes due to adverse climate or hazards asap to

EUSI, and Airbus ASAP (2 weeks specs)

• Now you should also insert aerial acquisition dates in G4CAP. This will trigger

dead period, and then next window opening

• Always use G4CAP for all interactions; avoid sending bilateral emails. If in doubt

contact [email protected] of the GTCAP/CAPISA image acquisition

team

• Set your e-mail notifications correctly so you get right e-mails !

mailto:[email protected]

Conclusions

Budget in line with Thessaloniki reductions

• MS to follow up ‘efficient image use’ during 2016 and prepare for 2017

Campaign status on line

• HR-1 window over central EU difficult due to bad weather (FR)

• VHR 50% acquired

• HR 50% acquired

• LPIS 80% acquired

Short term:

S2 usage in place of the ‘low resolution’ HR and more where possible …
