The problems
© 2016 - ADIE 4
A key resource for economic
and social development
Access to information

The problems
© 2016 - ADIE 5
X
1. Difficulties to share geospatial
information (GI)
2. Lack of permanence and scope
Several projects are carried out…
( Absence of data storage and
dissemination system)

The problems
© 2016 - ADIE 6
3. Difficulties in financing
projects and assets
Hence the need to mutualise
financial resources
4. …specially without
concerted action
But there is now the
organizational framework!

The problems
© 2016 - ADIE 7
Coordinates,
geodesy,
Webmapping…
What are you
talking about?
5. Difficulties in establishing clear communication
on the concrete benefits of the Geospatial Information
GNP has helped a lot through its communication
component !!

Décret Présidentiel 2009-799 du 6 aout 2009
formalizing the GICC
 The Inter-institutional Concertation and Coordination
Group in Geomatics is the framework for the exchange,
consultation, guidance and management of projects
related to geomatics, in particular the development and
implementation of the National Geomatics Plan (NGP)
 GICC is governed by an Executive Secretariat (ADIE,
ANAT, CSE)
 GICC member structures: 37

The GSDI architecture is based on two simple
principles:
 Sharing common assets to reduce
redundancy and facilitate access through the
implementation of the GSDI core
 Respect the specific missions of the M / O by
allowing them to operate a thematic node of
their own, but which respects the principles
of interoperability

 A thematic node is
characterized by a
customization of the
geomatic environment
of a M / O but according
to rules of division
favoring a weak mesh
between the data, the
applications and the
technologies.

Applications

The SSRS
21
 Establishment of a GNSS permanent
station:
 To increase the accuracy of the
geodetic network
&
 To facilitate the acquisition of accurate
points
IMPROVEMENT OF THE SENEGALESE
SPATIAL REFERENCE SYSTEM
New Permanent Station
The GNSS-RTK equipment
makes it possible to position at
the lowest cost all over Senegal
high-precision points that can be
referred to any new major
structure.

Applications

The Geodatabase
22
 Thanks to the
Geodatabase, all
Senegalese have access
via Internet to a modern tool
providing various
information on a set of
geospatial data produced in
Senegal.
 This will make it possible to know the existing,
minimize duplication of efforts in order to reduce
project costs

The way forward
© 2016 - ADIE 28
• To strengthen the institutional framework through the establishment of
a national council on geographic information under the presidency of
the Head of States or the Prime Minister;
• To elaborate of a three-year plan to implement the GNP and articulate
it to the Emergent Senegal Plan and the Act 3 of decentralization;
• To strengthen the GSDI core through the improvement of the geodetic
and leveling repository, the cartographic reference scales and the
geographic information access and exchange tools ;
• To work on the capacity building of actors and the integration of
Geomatics in higher and professional education curricula.
