THE PROCESS

2

pace



User Requirements will evolve over time.

Emerging new requirements from thematic DGs

New methodological developments

Paradigm shift: from (almost) mono-temporal to long time series analysis

Big data and WPS challenge

New and extending satellite sensor capacities

They should be categorised, e.g:

Now Still within this MFF

Mid-term >2020

Long-term >2028 (i.e.: Next gen. Sentinels)

(End-)users can be expected to have considerable difficulties with mid-and long-term

User requirements as a process

Land monitoring stakeholder consultation

Stepwise and iterative consultation:

1. DG ENV thematic units2. EEA thematic units3. other thematic DGs (REGIO,

AGRI, MOVE…)

4. Eionet NFPs and NRCs5. Copernicus User Forum6. etc…

Service selection criteria: Continuation of established

time series of core services Existence of a concrete request

(cfr. consultation) Relevance for underpinning

legal framework (reporting obligations)

Priorities set out in the 7th

Environment Action Programme Technical feasibility Gaps analysis in European data

needs Budgetary feasibility etc…

Copernicus Land: ensuring continuity

CLC and CLCC:

continued every 6 year; next run: 2018

evolving methodology: bringing EAGLE matrix model to an operational status

CLC around sea basins (Black sea, Mediterranean) ?

HRLs: planned intermediate and complementary to CLC

continued every 3 years, next runs: 2015, 2018

from 2015: exploring working with yearly incremental updates

content: repetition and improvement of existing 5 HRLs

Re-analysis imperviousness

Local component:

continuation of Urban Atlas: 2015, 2018

Riparian zones: 2012, 2018

Copernicus Land: short term new & extended services

New HRLs: pan-European green linear

elements using results of precursor studies

(ESA, GIO) experience from GLEs in Riparian

Zones experience from street trees in Urban

Atlas

improve grassland / intensity of agricultural management

geo-hazard zones ? biofuel crop monitoring ?

New (elements in) local components: Urban Atlas:

inclusion of 3rd dimension extension to EEA39

Riparian Zones: extension upstream Strahler level 3 ?

Natura2000 monitoring Second series of sites, TBD by DG

ADAPTATION OF SPECIFICATIONS

9

pace



GIO-land HRL production - 2012 reference year challenging conditions

Input imagery: lack of timely availability of initial contiguous, high quality image coverage with adequate acquisition timing

Products with different level of maturity for continental scale operational implementation

Ensuring harmonized production across lots: EEA39 was split up partly (for 3 products) in 5 lots (geographically)

Production in national projections (with late stage re-projection to European Projection)

10

pace



GIO-land HRL production - 2012 reference year challenging conditions

Complex and highly interdependent workflow involving: 39 countries, 6 lots (each with consortia with sub-contractors), 3 ETC partners and project management team at EEA

Lack of fully detailed product specifications at start of project

Difficult access to national in-situ data

11

pace



2012: Production of imperviousness and forest products in 5 lots

12

pace



Complex interdependent workflow

13

• 5 main products, but in reality large

number of deliverables (20m and

100m, additional support layer, 2

forest products)

• Production by 6 lots (with sub-

contractors)

• At least 4 semantic checks by 3

different ETC partners for each

deliverable (more in case of

rejections)

• Verification of each product by 39

countries

• Enhancement of each product by 39

countries

pace



Planned future improvements from lessons learned– generic improvements (all products)

One product – one lot. One lot produces one (or more) products for the whole EEA39 area. No more geographic splits within the same product.

Production fully in European Projection (re-projection where needed only after production)

Various improvement in ESA DWH for Image 2015 (implemented with ESA in the last years). E.g. regarding acquisition windows and standardized detailed documentation and rejection criteria

Simplified production workflow, with less interdependencies and less ETC checks.

14

pace



Planned future improvements from lessons learned–generic improvements (all products) – continued

No enhancement by countries: Focus of country involvement on Verification, Enhancement moves to SP responsibility

Fully defined product specifications earlier in project

Further improvement of existing online production platform

Define in detail method for quantitative product quality evaluation for production and final independent validation

Improve product documentation, e.g. by introducing additional layers identifying for each pixel which scene(s) has been used for classification

15

pace



Planned future improvements from lessons learned–Imperviousness

Improved calibration of sealing values and agreement on quality control of harmonisation across country boundaries

Time series re-processing: Corrected status layers for whole time series (including 2006-2009-2012) and change products

Added detail and clarifications in product specifications and definitions

16

pace



Planned future improvements from lessons learned–forest

Improved calibration of tree cover density (TCD) values and agreement on quality control of harmonisation across country boundaries

Possibly correction/re-processing of parts of TCD 2012 product to correct for calibration problems

17

pace



Planned future improvements from lessons learned–Grassland

2012: Initial grassland (GRA) product problematic and was not continued. Additional production of more limited natural and semi-natural grassland product (NGR)

2015: planned to go back to a wider grassland definition to include managed and intensely used grassland

Anticipated move to methodology that includes more multi-temporal imagery for improved separation from crops and information on use intensity

18

pace



Planned future improvements from lessons learned–wetland and water

To avoid confusion and wrong expectations: Re-naming from “wetland” to a combined “water and wetness layer” under discussion

Mapping of wetness, not of “wetlands”

Use imagery from a number of years initially to create a good “baseline” – later regular updates foreseen in synch with the other HRL’s
