Project

WP1 – Management and Reporting

The aim of this work package is to ensure effective work mode, smooth communication between partners, delivery of products according to project schedule and dissemination of the project’s results. The aim will be fulfilled by preparation of the detailed work plan and monitoring of the project’s progress through meetings with WP leaders and reports. All activities related to feeding information portal with EO-based products and their dissemination / promotion will be supervised by management staff, as well as IPR related to the developed technologies. Organisation of Kick off Meeting, Progress Meetings and Final Review Meeting, preparation of supporting documentation.

WP2 – Scientific review and requirements consolidation

Within this task a thorough review  peer-reviewed scientific publications and ESA technical reports will be done in order to determine state-of-the-art in the field of deriving land products from  new-generation optical satellite images. This review will cover methods of radiometric pre-processing of satellite data including models of atmospheric correction, methods of deriving biophysical parameters describing vegetation condition and approaches for generating maps characterizing vegetation status based on multi-temporal data. In parallel, methods of validating EO based land products with the use of ground collected information will be thoroughly analysed in the literature.

As a result of task execution the final report in the form of Requirement Baseline Document will be produced; it will include all recommendations obtained from scientific review, related to establishing a structured set of requirements to be followed in order to conduct the whole project.

WP3 – Algorithms and methods definition

This task will be aimed at development of algorithms and methods optimally adjusted to derive biophysical parameters from data collected by Proba-V, Sentinel-2 and Sentinel-3 sensors. The set of parameters will include:

  • Leaf Area Index (LAI);
  • Fraction of Absorbed Photosynthetically Active Radiation (fAPAR);
  • Fraction of Vegetation Cover ((FCover);
  • Carbon Balance;
  • Vegetation indices (NDVI, EVI, GEMI).

Development of the methodology will be based on the previous experience of the Institute of Geodesy and Cartography and the recommendations drawn from the literature review performed within Task 1.

The Task 2 will be divided into three subtasks:

  • 2.1. Proba V algorithms and methods definition;
  • 2.2. Sentinel- 2 algorithms and methods definition;
  • 2.3. Sentinel- 3 algorithms and methods definition.

All the above tasks will be supervised by professor Katarzyna Dabrowska-Zielinska, well experienced specialist in this domain, the tasks will be also carried out by the specialists, respectively: Maciej Bartold, Karol Paradowski. Those persons have the required knowledge and experience in satellite data processing.

The developed methods will be described in an Algorithm Theoretical Basis Document (ATBD), which will provide a justification for the method selection, and explanation of the needed EO and auxiliary data as well as of the best candidates test sites for validation. The developed algorithm will adopt error propagation method, which allows for full characterization and traceability of product’s uncertainty following quality assurance procedures for Earth Observation data.

WP4 – Validation plan and field campaigns

Validation approach following widely accepted protocols will be prepared at first part of the task realisation. Next, test sites for validation purposes will be selected; they will be representative for various vegetation types and soil moisture conditions in Poland. The plan for in-situ validation measurements will take into account both vegetation phenology and types of land monitoring products. Set of ground measurements will include:

  • Leaf Area Index (LAI) (with LAI-2000 and LAI 2200 Plant Canopy Analyser);
  • Soil moisture (with TRIME Field Measurement Devices);
  • Wet and dry biomass (in a laboratory, from samples collected at measurement plots from the area of 0.5 x 0.5 m);
  • Height of vegetation;
  • APAR (with AccuPar instrument);
  • Carbon balance (with chamber method and Eddy-Covariance method);
  • Type of vegetation cover and its development stage.

In addition meteorological data will be collected for the regions of interest to support validation dataset.

Schedule of validation measurements will be adjusted to overpasses of Proba-V, Sentinel-2 and *Sentinel-3 satellites. Validation Plan, including description of the selected areas, available instrumentation for ground measurements and field campaign schedule, will be prepared.

WP5 – Algorithms and methods validation

Within this task a comprehensive validation procedure of the land products generated on the basis of Proba_V, Sentinel – 2 and Sentinel- 3 data will be performed. The respective persons, responsible for conduction of Subtasks 2.1. – 2.3. will be also appointed to the delivery of the validation procedures. The methodologies specified at the Quality Assurance for Earth Observaton guidelines will be applied. All data collected in the course of field campaigns will be applied for validation. In addition data collected from other datasets, like BELMANIP-2 network or Copernicus Global Land Service, will be used for cross-validation and for filling gaps in ground measurements.
As a result of the work within this work package Validation Report will be prepared. The report will include all findings related to evaluation of method performance and product’s accuracy.

WP6 – Support to Proba-V, Sentinel-2 and Sentinel-3 Calibration/Validation activity

The output of the validation activities to contribute to the quality assessment of the ESA optical sensors measurements. Feedback on image quality and calibration (radiometric and geometric). Support of CAL/VAL activities. Qualifications of error of the used optical sensor products

WP7 – Land monitoring applications

Derived biophysical parameters and ancillary data (as  meteorological parameters) will be used for land monitoring studies of wetland and agricultural areas in Poland, including vegetation status mapping, vegetation hazards (drought, flood) mapping, crop classification and crop yields estimation. The following land products will be generated: maps describing vegetation condition for the areas of interest, e.g. maps of wetland habitats and cover type, maps of vegetation indices (NDVI, EVI, GEMI), maps of vegetation hazards, maps of LAI.

The plant biomass production and evaporation plant growth simulation model will be applied. The model will use as input meteorological data and periodic estimate of GLAI and evapotranspiration (E) derived from remotely sensed data.

This Task will be divided into SubTasks:

  • 6.1 Maps of  Vegetation status, conditions, cover type, crop classification (responsible dr M. Budzynska land specialist; maps of land use and hazards – responsible specialist dr A. Hoscilo);

  • 6.2 Crop growth model – increase of biomass( K. Dabrowska – Zielinska).

WP8 – Project outreach

Promotion and dissemination activities related to the project’s results.

  • web page, presenting new scientific results will be prepared in cooperation with the ESA EO Communication Team;

  • scientific publication will be generated describing the performed validation activities and results. An additional publication will be prepared presenting the Land Monitoring application results and the application of the plant growth simulation model;

  • participation to Conference and Workshops is planned in order to present and discuss the results within the Land Products Users Community.
