3 What is LUKR? LUKR is an abbreviation for Landupplýsingakerfi Reykjavíkur (The Land Information System of the Reykjavik Area). LUKR is a cooperative project of the technical departments of The City of Reykjavik (52%), Reykjavik Energy (36%) and Míla Telecom Company (12%). The task: Management and Development of the Reykjavik GIS.

4 More about LUKR The buildings and lots in LUKR are connected to corresponding records in the Building Inspector's database, the National Real Estate Registry and the National Population Registry. LUKR spans 15 basic themes (layers), more than 200 others themes and more than 100 tables. LUKR covers the Reykjavik municipality area of 270 km², including an urban area of 45 km². The total population of the Reykjavik urban area is about inhabitants, thereof about reside in the City of Reykjavik.

5 The Development of LUKR 1 st S T A G E 2 nd S T A G E Formal co-operation begins Feb City Council decides to start LUKR project July 1989 Arc/Info software from ESRI chosen in open bidding Nov Beginning of general data input May 1990 High speed connections between LUKR participants Des Input of all basic data themes finished Jan Data delivery on the Internet Feb Usage of SDE (Spatial Database Engine) from 1997 Development of City View on PC-Windows Development of City WebView on the Internet from 1999 Development of City PlannigView on the Internet from 2003 Dev. of City View on Internet with ArcGIS Server from 2004 Development of more web services with ArcGIS Server from 2007 (LUKR Time Machine 2008, Public Works Map Viewer 2011)

6 Cooperation, Coordination and Interconnection These three keystones must be kept in mind all the time if a GIS shall get maximal usefulness. Coordinated data, contact persons, committees and high speed connections make all the LUKR layers acting as a whole. Meetings are hold regularly: - Technical meetings about once a month. - Board meetings twice a year.

9 What is Borgarvefsjá? Borgarvefsjá (City WebView) is a simple information system on the Web. It is based on ArcGIS Server and the LUKR data and gives access to various information about Reykjavik. Borgarvefsjá gives the public access to information about houses, lots, streets, areas, lots drawings, streets drawings, buildings drawings, etc. It s also possible to look at aerial photos, find an address on the map, get information of pipelines/cables, measure distances or areas, store locations, etc. Borgarvefsjá is accessible for the public on the Web. The Web path is:

10 City WebView (Borgarvefsjá) - content Map display and features Theme selection Map and Aerial photo switch Search for addresses or streets Measure coordinates, lengths and areas Store and retrieve locations Display utilities Query attributes Display drawings Print maps

11 City WebView-app (Borgarvefsjá) - content Map display and features Theme selection Query attributes Search for addresses or streets Measure coordinates, lengths and areas

12 LUKR Time Machine (Tímavél LUKR) Compares LUKR databases at two different points in time. Based on database snapshots taken December 1st every year since Possibility to slide over time to see changes gradually. Print comparative maps.

13 What is Borgarsjá? Borgarsjá (City View) is an easy but powerful Web application where you can get access to many kinds of information about Reykjavik and vicinity. Borgarsjá is based on ArcGIS Server, giving many possibilities, like access control of information. Borgarsjá is a tool for looking at and querying or combining information from LUKR, Building Inspector s database, the Real Estate File for Iceland and the National Registry. Borgarsjá is accessible for all employees of the City of Reykjavik and the Reykjavik Energy and others according to agreements.

15 What is Skipulagssjá Skipulagssjá (City Planning View) gives the public users information about master plan and local plans. Skipulagssjá (City Planning View) is based on ArcGIS Server. Skipulagssjá (City Planning View) is a tool that gives informations about local planning by connection to scanned papers and maps. The master plan is however build in geodatabase. Skipulagssjá (City Planning View) is accessible for the public on the Web.

17 Access to LUKR data Since 1997 LUKR data has been available on the Web. Users had to pay license fee until the year Now all data is free and available for everone. Part of Reykjavik City open data policy. Private companys and individuals can use the data in new way and in a new context - and then increase the value. Possibly even create new jobs. We get more feedback on our data to make them more accurate.

18 Data delivery on the Web LUKR has a Web page where it is possible to download zipped shapefiles of 44 themes from LUKR. Themes are updated few times every year.

19 Data delivery on the Web Úttektarkerfi LUKR - Web application to deliver data to LUKR clients. After logging in user selects: 1. File Type (Shape or dxf) 2. Layers 3. Area 4. Coordinate system (National or local) Data is extracted and zipped.

20 A few examples of how LUKR is used (1) Live information of snowplowing.

21 A few examples of how LUKR is used (2) Percent of kids that practice sport with each local team

22 A few examples of how LUKR is used (3) Heatmap of rat-incidents compared with age of the sewage system

23 A few examples of how LUKR is used (4) Graffiti and tags in city center

24 A few examples of how LUKR is used (5) People were able to map their cycling path to work - the result was used to plan new cycling paths.

25 The Benefits of LUKR Information source both for specialists and for the general public. Base for data processing and research. Aid for management and decision making. Coordinating tool for institutions, departments and companies. Aid for teaching.... and the Goals of LUKR To stay among the leaders in GIS world. Serving employees and general public as well as possible.

26 Technical Overview Software ArcGIS 10.x used by everybody ArcSDE 10.0 (soon to be upgraded) ArcGIS Server (upgrade in progress) ArcGIS Desktop ArcGIS Online in beginning phase Web clients ArcGIS API for Javascript ArcGIS API for Flex (in process of being replaced) ArcGIS API for Silverlight (already been replaced) Mobile clients ios Android

27 Technical Overview Data replication From beginning the same principle has been used: Data that each party owns and maintains copied automatically to Reykjavik City where others can access or copy to themselves. Web Apps Web Apps ArcMap View ArcMap Edit RVK Míla RE Reykjavik Energy and Mila have their own desktop clients and internal and external web apps.

28 Technical Overview Data replication Data copied at least weekly Firewalls have been opened for ArcSDE port Direct Connections - not yet Python scripts to copy data. ArcSDE connection established Transfer details read from table If source data is OK, target is replaced Run as Windows scheduled task Error handling and messaging to system administrators Log files Windows event viewer

29 Technical Overview Data Analysis Data for display, query and analysis kept seperate from production Avoid schema locking Better access control Replication done by python script once a day Same process as described earlier. Can be run manually if need arise Replication process also joins features to external tabular data Speeds up and simplifies queries in Web Apps Application independent queries, can be done in ArcMap Type of joins Building and apartment size Age of buildings Value of buildings Owners and inhabitants Etc. Some joins are just spatially enabling tabular data. Every apartment or person is a point in a feature class

30 Technical Overview Data Analysis and display All web applications use one of 2 basemaps. Cached automatically in parts by python scripts Cached in scales from 1: to 1:200 Entire area renewed in one week
