Fundamental Base of Geographic Data of the Czech Republic (ZABAGED ® ) and Database of Geographical Names (Geonames) Pavel Šidlichovský 30 th September 2010

Legal frame in law no. 200/1994 about surveing Digital topographic model of the Czech Republic territory Level of details matches the scale 1: „Spaghetti“ model (lines, centroids, + areas added in new platform) Organized in three levels 8 categories of objects 122 object types ca attributes 2D planimetry component and 3D altimetry component (contours and elevation) ZABAGED ® - basics

Feature type categorization: 1.Build-up areas 2.Transport networks 3.Energy and product networks and pipelines 4.Hydrography 5.Administrative units, including enviromentaly protected areas. 6.Landcover 7.Terrain 8.Geodetic control Object catalog of ZABAGED ® is living document, updated to describe current state of distributed types Content of ZABAGED ® in categories

1994 – 1995 Scanning of analogue map master films 1994 – 2005 Creating and first updating the Fundamental Base of Geographic Data (ZABAGED ® ) 2000 – 2006 Generating of the Basic Map 1: from ZABAGED ® 2006 – 2009  Fundamental technology upgrade of database maintenance and updating platform  3 years updating cycle  Continuous updating of selected objects  New object classes (street names, address points)  Steps toward Integration (Geonames,……) 2009 Finishing the generating of all basic medium scale maps derived from ZABAGED ® ZABAGED ® - periods of development

Information sources for updating ZABAGED Aerial imagery and orthofotos (geometry of most objects) External databases – cooperation with data creators oCzech statistical office (CSÚ) : cooperation on improving and continuous maintenance of adress points dataset, street names and lowest level administrative units oRoad and motorway directorate (ŘSD): cooperation on maintanance ofinformation about road networks and related objects oCentral evidence of water bodies (CEVT), managed under Ministry of agriculture, distributed to riverbasin directorates: pilot project with Elbe basin oTransport research centre (CDV): information on raiload stations, basic railroad network identifiers, airports. oForest Management institute (UHUL): Usage of their WMS service oAgency for nature conservation and landscape protection of the CR (AOPK) : provides nature preserves boundaries oCzech office for surveying mapping and cadastre (COSMC): update of building in testing. Cadastral boundaries, so far accessed just in WMS and „interpreted“ into our data Internet (lists of schools, post offices, government offices) Field revision ( if everything else fails…)

Workflow of periodic updating 1) Preparation phase change detection using various sources 2) Terrain survey 3) Data updating 4) Commiting changes to central base 5) Data presentation through: “geoportal.cuzk.cz” repeat in three years

Geonames Geographical names are standardized by authority, which is The Commision on Geographical Names of COSMC Commision cooperates with UNGEGN (United Nations Group of Experts on Geographical Names) and participates at Eurogeonames project Geonames is a database, tool used for registering the standardized names as well as for easy access to the data. Principal scale for witch the names are standardized is 1:10000

History of standardization Work started at 1931, for map 1:75000 Since 1958 work is done for 1:10000 base maps Up to the 1998 the information was maintained on paper cards During period information was verified and stored in database there was an updating cycle going on, which coresponded to updating of ZABAGED and regional topografic departments were involved – integration step between ZABAGED and Geonames, shift towards database of names of geographical objects, from database of names for base maps.

ZABAGED/Geonames integration Geonames before: database of names on base map, so many instances of one name, as was printed on base map sheets. ( larger objects= many instances ) Each name had its cartographic position and rotation Good for map production, not so good for web seamless presentation. Geonames after: Only single name for geographical object, with relation to corresponding graphic elements in ZABAGED, where aplicable, or relation to fictitious object created in geonames Position and rotation of text has to be derived by aplications

Future goals Shift from periodic to continuous updating of ZABAGED Even closer integration with Geonames Integrating keys – links to thematic databases Better accuracy through better reference orthoimagery, laserscan „imagery“ and cadastral data Availability through web technologies Seamless at state borders !

Thank you for your attention.
