Vegetation Preparatory Programme (VPP)


To stimulate the interest of a broad users community to the potential of the VEGETATION system and to prepare the users to efficiently integrate VEGETATION data into their own projects.

This programme is dedicated to some actions to support developments related to the specific characteristics of the VEGETATION system. Specific fields have been defined as priorities for the investigations:

  1. support for development or adaptation of applications or scientific projects using VEGETATION type data
    • to better evaluate the impact of the use of VEGETATION on the quality and operationality of the projects
    • and to prepare the integration of VEGETATION products into the systems and procedures which contribute to the objectives of these projects.
      A high priority is given to investigations which are related to the sectorial policies of the European Union, and to activities, both for application and for science, which are supported either by the European Commission or by the partners of the programme.
  2. development of methodologies for the use of remote sensing data, exclusively where the specific characteristics of VEGETATION can offer new capabilities or imply research and development activities to improve the quality of informations which can be extracted from the VEGETATION products.
    The topics which are priorities for selection are the following :
    • multiscale analysis using simultaneous or asynchronous high spatial resolution data and possibly ground sampling techniques,
    • multitemporal analysis related to the dynamics of the surface processes, physical and biophysical parameters extraction.
  3. definition of improved products that could be generated by the VEGETATION Ground segment making full use of the specific characteristics : capability to improve the standard VEGETATION products is a specification for the entire system and should be possible with a frequency of every 18 months or two years; while the first set of products is now defined and should be kept for development efficiency, minor modifications might be considered and definition of evolution for the first update is expected from some investigations.

The basic objectives of the VEGETATION Preparatory Programme are :

  • to foster development of methodologies for the use of medium spatial resolution and high frequency remote sensing data for vegetation studies.
    As VEGETATION will provide products which are tailored specifically to improve quality of measurements on vegetation canopies, it is among the roles of the Programme to participate to the effort of the users community to develop its ability to extract the most adequate information from this kind of data sets.
  • to prepare the integration of VEGETATION data sets into existing or still under development projects which are routinely using or will use before 1997 similar data sets.
    As the design was entirely based on general methodologies which are already known, it is expected that the VEGETATION data sets can be included almost directly in the existing projects as soon as they are available. Improvements due to the quality and adaptation of VEGETATION data sets can also be prepared in advance to benefit from the system as soon as possible.
