• Co-decision procedure
• Preparation of Implementing Rules
• Transposition phase (2007-2008)
• Directive enters into force
• Transposition into national legislation
• INSPIRE Committee starts its activities
• Adoption of Implementation Rules by Committology
• Implementation phase (2009-2013)
• implementation and monitoring of measures

Co-Decision Call for Participation

• INSPIRE Work Programme (Preparatory Phase)
  published 4th February 2005
• European Parliament amendments to be debated
  20-21st April
• 11th March 2005 Call for Expression of Interest
  for INSPIRE development
• Open, permanent call
• Call for experts, projects and reference material
• Open to any organisation or network with an
  interest in the spatial information themes and
  services referred to in the INSPIRE proposal
• The initial composition of the Drafting Teams
  will be formed on the basis of experts that are
  proposed until 15 April 2005. Experts proposed
  after 15 April 2005 will constitute a reserve
  pool which can be used according to the needs and
  which could be involved in the review of the
  proposals of the Drafting Teams.

Spatial data harmonisation requirements

• Comprises
• Harmonised data specifications
• Arrangements for the exchange of spatial data
• Annex I, II, III data
• the definition and classification of the spatial
  objects relevant to the spatial data and the way
  in which they are geo-referenced.
• Annex I, II data
• a common system of unique identifiers for spatial
  objects
• the relationship between spatial objects
• the key attributes and the corresponding
  multilingual thesauri commonly required for a
  wide range of thematic policies
• exchange of information on the temporal dimension
  of the data
• exchange of updates of the data.

17
Spatial data harmonisation requirements

• Timeline harmonisation
• IR adopted 2 years after the entry into force of
  INSPIRE for the Annex I spatial data sets 2009
• By 5 years 2011 for the data sets listed in
  Annex II and Annex III.
• Timeline exchange
• IR on the arrangements for the exchange of
  spatial data in Annexes I, II and III will be
  adopted 2 years after the entry into force of
  INSPIRE 2009.

18
Network services and interoperability
requirements

• The Directive will require Member States to
  establish and operate a network of the following
  services for the spatial data sets and metadata
• Upload services
• Discovery services
• View services
• Download services
• Transformation services,
• Invoke spatial data services services, enabling
  data services to be activated.

19
Spatial Data Interest Communities

• Complexity of INSPIRE requires
• Participation of stakeholder
• Respect for existing systems and experience
• Networked approach
• Work Programme envisages Spatial Data Interest
  Communities
• Organised by region, by industrial sector and
  thematic issue
• Each with its own audience of data providers and
  users looking to explore spatial data

20
Spatial Data Interest Communities

• SDICs roles in the drafting, review and testing
  of the Implementing rules
• To identify and describe user requirements
• To provide expertise to INSPIRE drafting teams
• To participate in the review process of the draft
  Implementing Rules
• To develop, operate and evaluate implementation
  pilot projects
• To develop initiatives for guidance, awareness
  raising and training in relation with the INSPIRE
  implementation.

Ideas for processing services

• JRC active in algorithm development
• Feature extraction, cloud removal, compositing
• Strong emphasis on morphological techniques
• Proposal for Automatic Image Compositing of
  Regions of Interest

Morphological Compositing of Satellite Images
Morphological compositing automatically
generates image cut lines as well as cloud masks
based on morphological constraints
Morphological compositing improves temporal
cloud/shadow masking by replacing surrounding
pixels based on morphological constraints

Automatic Image Compositing generated in ENVI
Automatic Morphological Compositing
The morphological compositing algorithm proceeds
based on the number of overlapping images within
any given region. Consequently, regions with no
overlap are not processed and regions where two
images cover the same area are processed
first.The next regions to be processed will be
those areas where three images cover the same
region and so forth. If there are regions where
more than three images overlap then they will be
processed next and so on. The Ireland example
(shown above right) contained 9 Landsat images
which was pushing the memory limit of our
computers because all images needed to be
processed at once. A more general algorithm was
required in order to process larger countries or
the entire European Union.
25
Morphological Compositing of Satellite Images A
Generalised Algorithm to Process one Image at a
Time
The problem is to process any number of
overlapping images. The figure to the left shows
a simple example of four images that are
overlapping for which a mosaic is to be produced.
Due to memory restrictions, all four images
cannot be processed at the same time. The
solution is to process a single image at a time.
In order to process in this manner one needs to
know 1. Which images overlap the anchor image
(the image being processed) and 2. The number of
overlapping images in each region of overlap.
The information about image overlap (1) can be
obtained by checking for each anchor image
whether any of the other images fall within the
anchor image. Based on these results an overlap
matrix (right figure top) can be generated which
clearly shows image overlap. The advantage of
this method is that processing will than only
need to be done on the upper right half of the
overlap matrix. However, based on this overlap
matrix there is no way of knowing the number of
images that are overlapping for any specific
region (right figure bottom).
In order to generate results similar to those
when the entire mosaic is processed at once, it
is necessary to process each overlap level in
sequence. For example, regions where there is
overlap of 2 images are processed first then
regions where there is overlap of 3 images, etc.
