The use of open software in the Danish State and local authorities

Presentation by Morten Bilde Kias M.Sc.Geography GIS Coordinator at Ministry of Environment Vice-Chairman of the Danish QGIS user group



Tip: Alt + F9 for hurtig visning af hjælpelinjerOverview of presentation

• A few ”fun” facts about Denmark• The beginning of FOSS in Denmark• QGIS in Denmark • Use of QGIS in SVANA (the Ministry of

the Environment) • Plugins• Set data free• Change2D project• Free beer!




• 5,6 million inhabitants• 43.000 square kilometres• High agricultural production

and very little forest left (14%)

Facts about Denmark




Sentinel for Monitoring the status of Europe´s forests




• ”FOSS was first mentioned in ”the Danish Government software strategy” in 2003

• In 2007: First actual strategy/policy on Open source software.• This led to the creation of the SoftwareExchange platform.• 45 Open source projects across government agencies.• Virk.dk portal with 1300 reporting services, based on OIO

open standart.• Digitalisér.dk (Knowledge center for software).

“Open Source Software” in the Danish Public Sector




QGIS in Denmark• QGIS Usergroup Denmark established in 2015• Today we have aprox. 250 members • Several meetings in different parts of the country every year.• Our board consist of Government agencies, municipalities,

private companies and universities.• We share danish plugins and knowledge about QGIS • Translate Qgis into Danish

Tip: Alt + F9 for hurtig visning af hjælpelinjerUser survey: QGIS Denmark

• Most members of QGIS usergroup DK have been using QGIS for a few years (48%) or have just started using QGIS (25%).

• Only 10% of our menbers have switched completely to QGIS, still relying on MapInfo (70%) and/or ArcGIS (40%)

• Most of our members use a variety of Open Source products, such as PostGIS/PostGre SQL, GeoServer, Open Layers, Leaflet og Grass-GIS

• Reasons for using QGIS; Save license money (70%), Growing number of plugins (60%) and Open source code means that we are free to choose developer.

• Encountered problems; Lack of QGIS competensies (55%), resistance from users (40%), no problems (25%)




What was our original situation 2 years ago?• 1200 employees • +400 MapInfo licenses• 40 ArcGIS licenses• No QGIS!• No DB storage, flat files in folders with copies of

gis files in both MapInfo and ArcGIS • Little or no meta data!

Use of QGIS in SVANA* - 1

*Styrelsen for Vand og Naturforvaltning




Where did we want to be?• Reduce number of licenses for MapInfo and

ArcGIS • Ideally... Only using QGIS (for desktop GIS) • Structure all data in Open Source DB• Meta data for alle data• Open source WebGIS• Open source mobile platform

Use of QGIS in SVANA - 2




What was the result?• Divided into 2 agencies (time comsuming

restructuring!)• +400 MapInfo licenses 50 • 40 ArcGIS licenses 10-15• No QGIS 50• Metadata system set up, 50% of data have

meta data• No DB storage, risk of using outdated/wrong

data! But project on the way• Use of Open Source PostGIS / PostGre SQL DB

in our WebGIS , but not all open WebGIS





What went wrong?• Division of our agency has taken much time

and many resources !• Hard to make other departments prioritice

making meta data (which they are responsible for!)

• User resistance: Many MapInfo users have only known and used MI for +10-15 years!

• Lack of competances • Its difficult to identify the correct version of

files to keep and store in DB!





Lessons learned• You need to ”get out there” and show it off• How can QGIS solve their job better /faster• Make ambassadores for QGIS • Not everybody need to use Desktop GIS, many

are better of with WebGIS (Don’t force users!)• Need to show why meta data is so important

(Reduce risk of using outdated data!)• Write QGIS/OpenSource into GIS strategy to

show the accept of top leadership.





QGIS plugins making it easier to implement QGIS• Kortforsyning plugin (easy access to all the free data

(Denmark)• Geosearch Denmark (Search and zoom to named places,

adresses and parcels in Denmark)• Turturials at GitHub• Semi-Automatic Classification Plugin• Print composer - Atlas

• The Basic Danish Data Programme• Core data about Individuals,

Businesses, Real properties/Buildings and Aerial photo and topographic Maps.

• Leads to development of plugins that use the free data

• Increased use of the data• Thus better chance of finding error

and therefore better data.

Effects of Opening up data




Change 2D projectChange Detection – Dynamic Denmark• National funding (innovation fund) for increased use of

satelitte data, specially the new Sentinel data.• Project team consist of Private company, public

authorities, universities and NGO • Develop innovative and robust algorithms that reliably

and automatically can screen large time series for changes in key areas, such as agriculture, infrastructure and forestry.




Change 2D project - 2

• Forest monitoring in Denmark and Latin America from Sentinel 1 + 2 as a case story

• With CHANGE2D we want to develop tools that allows for an automatic and systematic change detection based on a joint combination of the vast amount of Sentinel 1 and 2 data that is made available on a weekly basis.

• Combined use of the Sentinel 1 SAR and Sentinel 2 optical imagery.• Pairwise comparisons makes it virtually impossible to control the

rates of false positives (postulating a change when there actually is none) and of false negatives (missing an actual change). In general, a better approach for comparing several distributions is to perform a simultaneous test of the hypothesis of homogeneity of the said distributions, and we have very recently presented a novel method that is able to do this in a series of SAR images

DHI GRAS – in short




You cannot sell a free beer, but you can…

• Sell the knowledge of how to open the free beer,

• A ready-to-use bottle opener,

• Some ideas on how you enjoy the free beer the most.

• In other words…

• Implementation, addaptation and maintenance costs

• ”Total cost of ownership”

• Innovation is not just about new tecnology!

• But also how to utilise software in new ways (re-cycle and re-think)

No such thing as a free beer
