Nature GISAccess to Information and GI
technology

• Implement a prototype that will offer the
  possibility to European Citizens, policy makers
  at all levels and different stakeholders to
  search, locate, retrieve and access geographic
  information about protected areas in Europe.
• The prototype will be based on International
  standards and specifications.

INSPIRE architectural vision

• The architecture envisioned by INSPIRE deploys
  interoperable services that will help to produce
  and publish, find and access, and eventually, use
  and understand geographic information over the
  Internet across European Union and Association
  Countries at local, national, and European levels

4
INSPIRE Principles
The following principles govern INSPIRE and will
be included in the legislation a) that spatial
data should be collected once and maintained at
the level where this can be done most
effectively b) that it must be possible to
combine seamlessly spatial data from different
sources across the EU and share it between many
users and applications c) that it must be
possible for spatial data collected at one level
of government to be shared between all the
different levels of government d) that spatial
data needed for good governance should be
available on conditions that are not restricting
its extensive use e) that it should be easy to
discover which spatial data is available, to
evaluate its fitness for purpose and to know
which conditions apply for its use.

What is a Web Map Server ?

• The OpenGIS Web Map Server Specification (WMS) is
  a set of interface specifications that provide
  uniform access by Web Clients to maps rendered by
  map servers on the Internet. Thus, WMS is a
  service interface specification that
• Enables the dynamic construction of a map as a
  picture, as a series of graphical elements, or as
  a packaged set of geographic feature data
• Answers basic queries about the content of the
  map
• Can inform other programs about the maps it can
  produce and which of those can be queried further

9
What is a Web Feature Server ?

• Whereas WMS delivers a picture, WFS supports the
  direct exploitation and access of feature data
  and associated attributes on the Web.
• The WFS is a service interface that describes
  data manipulation on geographic features. Data
  Manipulation operations include the ability to
  insert, delete, update, get and query features on
  spatial and non-spatial constraints

10
What is Portrayal ?

• Portrayal is a rule-based process to portray
  information based on the feature attributes
• To portray is the process that transforms the
  content in a presentation

What is Metadata ?

• Traditionally metadata has been understood as
  Data about Data
• Applications of Metadata
• Cataloging (Item and Collections)
• Resource Discovery
• Electronic Commerce
• Intelligent Software Agents
• Digital Signatures
• Content Rating
• Intellectual Property Rights
• Privacy Preferences Policies

13
Metadata for what ?

• There are different levels that metadata may be
  used for
• Discovery metadata - What data sets hold the
  sort of data I am interested in? This enable
  organizations to know and publicize what data
  holdings they have.
• Exploration metadata - Do the identified data
  sets contain sufficient information to enable a
  sensible analysis to be made for my purposes?
  This is documentation to be provided wit the data
  to ensure that others use the data correctly and
  wisely.
• Exploitation metadata What is the process of
  obtaining and using the data that are required?
  This helps end users and provider organisations
  to effectively store, reuse, maintain and archive
  their data holdings.
