Driver – eGovernment
Strong political mandate for digitization in
Denmark
Challenges for Danish economy:
• Productivity has grown too little
• Demographic profile – ageing population
• Tight public sector
Vision for eGovernment:
• Digital methods must contribute to a more
efficient and coherent public sector with a
high quality in service, and focused on
serving citizens and enterprises
Ministry of Finance in charge
Driver - Network Based Operations
”an information superiority-enabled concept of operations that
generates increased combat power by networking sensors, decision
makers, and shooters to achieve shared awareness, increased speed
of command, higher tempo of operations, greater lethality, increased
survivability, and degree of self–synchronization”

The Digital Map Supply
• The framework used by the Danish Geodata Agency to share spatial
information via the internet
• Addresses both technical and business issues for sharing
• Decreases technological and economical barriers for using spatial
data and functionality
• Increases availability of updated spatial data and functionality
• Interface between the SDI data content and its utilization

Public authorities in Denmark register
various core information about individuals,
businesses, real properties, buildings,
addresses, and more. This information,
called basic data, is re-used throughout the
public sector. Re-use of high-quality data is
an essential basis for public authorities to
perform their tasks properly and efficiently
across units, administrations and sectors.
http://www.digst.dk/Servicemenu/English/Digitisation/~/media/Files/English/Grunddata_UK_web_05102012_Publication.ashx
Main points in the basic data agreement
Yearly benefits of approx. € 35 million in public
sector and € 65 million in the private sector
Government investments for approx. € 125
million up to 2016
Free access to public sector basic data for
everybody – citizens and businesses
Improved quality for basic data regarding real
property, addresses, geography, individuals
and businesses
Effective, joint distribution of basic data
Danish population:
5 million people
Basic data – the content
The Data Distributor
• conveys updated and authentic
information from base registers
on to the relevant public and
private sector users
• based on the same conceptual
thinking as the Digital Map
Supply – which is also content
provider for INSPIRE data
• will fulfil the requirement for
accessing data in an easy, fast,
reliable and cost-effective
manner
• will save resources for data
responsible authorities
The goal: A national data infrastructure …
 that contains a complete, correct and current basic registration of all
objects important for public administration
 that is maintained in a cost-effective manner
 that is coherent, modelled uniformly and fully documented
 that is freely and fully available – technically, legally and economically
 that is used by all major public and private players
 that contributes to efficiency and productivity in the public and
private sector
