  1. Introduction to GIS For Slavic Humanists, Social Scientists and Librarians 2005 Slavic Digital Text Workshop Eileen Llona, University of Washington

  2. Using GIS for query and knowledge discovery • Combining layers: • Trade routes + architectural types + linguistic characteristics • Topography + population + agriculture • Population + literacy rates + unemployment rates • Historic boundaries + linguistic regions + topography

  3. Using GIS for query and knowledge discovery • Mapping Arabia (http://www.umich.edu/~iinet/ces/MiscHTML/mappingArabia.html) • ECAI Silk Road Atlas (http://ecai.org/silkroad/) • Central Asia in World History (http://sacarcims.sac.accd.edu/website/eurasia2/viewer.htm) • Central Eurasian Interactive Atlas (http://green.lib.washington.edu/website/ceir)

  4. Using the IS in GIS • Database technology can be exploited • Link existing, “unplaced” data to georeferenced data • How do you link attribute data to your maps? • How do you turn the word “Moskva” into something the computer can “place”?

  5. Creating new maps • Manually create a shapefile, adding attributes • Create a new layer, add attributes automagically (using database linking) • Run queries 2 or more map layers, create new map from result

  6. Creating new maps with db technology • Need to have ‘implicit’ references between 2 or more data sources • Codes for places

  7. Creating new maps with db technology • Need to have ‘implicit’ references between 2 or more data sources • Placenames

  8. Gazetteers • Tool for locating places on a map • Often gives generalized locations (i.e. points for large areas) • Can be used to help add spatial information to your database (which can then be added to a GIS)

  9. Gazetteers • Geonames • Alexandria Digital Library Gazetteer • CEIA Gazetteer

  10. Historical places • Some gazetteers handle • Usually have to make your own references • Look at historical documents, try to correlate to current places to get coordinates • Boundaries may be different • Vision of Britain
