2 Overview of the presentation Background introduction Data sources in Norway Digital First Pilot project Second Pilot Project Further work 2

3 KOSTRA municipality to state reporting The KOSTRA-project started in 1995 as project with four municipalities as participants. The first full scale reporting took place in March KOSTRA focuses on two purposes: To give better information about the municipalities, both for the central and for the local governments. (more coherent data collection to combine data from many sources, comparability between municipalities, to make benchmarking possible as a part of the management process, timeliness is vital). More efficient reporting. All data reporting from the municipalities are electronic, by use of electronic forms or file extracts. And the same data should be collected only once, even if it is used for many purposes. 3

4 Example on publishing - article 4

5 Example on publishing figures in StatBank 5

6 Example on publishing StatBank and PX-iMap 6

7 The projects 3 projects in for 4 steps Narrow pilot study on possibilities of map based reporting Broad pilot study on possibilities of map based reporting Develop system for alternative map based reporting Establish large scale map based reporting 7

8 Pilot project I: Small and narrow possibility study A few municipalities A few topics: Land management/planning data (regulations) Land cover/land use maps Water and sewage networks 8

9 Example: Regulation map with double surfaces Plan delineation Planavgrensing Danger area Fareområde Regulation purpose REGFORM Fritidsbebyggelse Leisure home area Jord og skogbruk Agriculture and forestry Leisure area water Friområde Leisure area land Friluftsområde May loose surfaces/polygons when - Converting between file formats - Transforming beteen coordinat systems 9

10 Agriculture Pasture Mixed forest Other soil Sales price. Norwegian crowns Example 2/2 : New statistics with CMD -data 10

11 Pilot project I: Further work Metadata: content, standards and file formats Routines for management of data bases Technical development Organisational development 11

12 Pilot project II: 2007 Part One : Broad possibility study All municipalities (430) All topics in Norway Digital (> 40 primary data sets) Part Two : Technical implementation pilot/scheme 12

13 Broader possibility study - Easier access to better data Norway Digital 13

19 Pilot project II: 2007 Part One Four main questions 1) Which of todays questions may be replaced by using map data? (-> ~14) 2) Which questions should be changed to be replaceable? (-> a few more) 3) Which map data are defined so that they might replace questions? (-> even some more) 4) Which adjustments has to be done with maps to replace questions? (-> a system change) +) possibilities for a lot of new statistics not covered by KOSTRA 19

20 Pilot project II: 2007 Part Two National Mapping Authority register WFS Architecturescheme (pilot) Internet GML Statistics Norway search engine Receiver - NMA transfers knowledge (WFS, GML, UML, SOSI) SSB geodatabase - Need testing in minor scale - Need develop/define searches 20

21 Pilot project II: 2007 Part Two Example : UML modell for adm. boundaries 21

22 Further work More knowledge building - revision of datacatchment model? (GIT, geostandards) Cooperation with NMA through Norway Digital projects (GeoPortal) Change in management of map databases 22
