  17. 17. Comparison of Thematic Map Viewer with other web-map applications: • L'Atlas Interactif des Régions Européennes (AIRE) (http://aire.ums- riate.fr/fr#content/index.fr.php) • Bremen Election Atlas: Federal Elections 2009 (http://www.statistik- bremen.de/tabellen/wahlen/Wahlatlasbtw2009_english/atlas.html) • De Nationale Atlas van Nederland – 3e editie (http://geoserver.itc.nl/NatAtlas/NatAtlasViewer/NatAtlasViewer.html#) • ESRI Demographic Atlas of USA (http://atlas.esri.com/Atlas/) • EUROSTAT statistical atlas: Regional yearbook 2013 (http://ec.europa.eu/eurostat/statistical-atlas/gis/viewer/) • HyperAtlas (http://hypercarte.espon.eu/HyperCarte/) • Interactive statistical atlas of Slovenia (http://stat.monolit.si/) • Swiss Statistical Atlas (http://www.atlas.bfs.admin.ch/core/projects/13/de- de/viewer.htm?13.0.de) GI2014 – GI/GIS/GDI – Forum Open GeoData Movement in Europe of Regions 14.

  22. 22. Differences: Atlas name Multi-scale Number of maps Number of techniques from thematic cartography used AIRE atlas Yes (user selects NUTS level from drop-down menu) 36 6 (choropleth,proportional symbols, discontinuity lines, anamorphose(cartogram), grid choropleth, potential isolines) Bremen Election Atlas No (with zooming units still the same and no visible generalization occurs) 33 1 (choropleth) De Nationale Atlas van Nederland – 3e editie No (not even zoomable) 29 2 (choropleth, proportional symbols) ESRI Demographic Atlas of USA Yes (with zooming user sees statistics for smaller administrative units) 20 1 (choropleth) EUROSTAT statistical atlas: Regional yearbook 2013 No (each map has definied NUTS level for which it is made) 78 1 (choropleth) HyperAtlas Yes (user selects NUTS level from drop-down menu) 24 2 (choropleth, proportional symbols) Interactive statistical atlas of Slovenia Yes (user can switch between regions/municipalities, also clicking on a region zooms in it's municipalities) 107 2 (choropleth, anamorphose(cartogram)) Swiss Statistical Atlas Yes (user selects level from drop-down list) >2000 3 (choropleth, graduated symbols,pie chart diagram maps) Thematic Map Viewer Yes (in vas majority of maps user sees data for smaller administraive unit with zooming 47 >10 (choropleth, structured choropleth, proportional symbols, pie chart diagram maps, square pie chart diagram maps, 'butterfly' graph diagram maps, isotype diagram maps, comparative bar diagram maps, demographic pyramid diagram maps, proportional spherical diagram maps, area qualitative maps, dot density maps) GI2014 – GI/GIS/GDI – Forum Open GeoData Movement in Europe of Regions 14.

  23. 23. Biggest difference: GI2014 – GI/GIS/GDI – Forum Open GeoData Movement in Europe of Regions 14. Grenzüberschreitendes Sächsisches GIS – Forum am 29./30. April 2014 in Dresden • Number of techniques used
  24. 24. Future improvements of Thematic Map Viewer: GI2014 – GI/GIS/GDI – Forum Open GeoData Movement in Europe of Regions 14. Grenzüberschreitendes Sächsisches GIS – Forum am 29./30. April 2014 in Dresden • Evaluating techniques of thematic cartography from the point of view of visualizing multi-temporal data (WMS-T services) step by step: • Doing synthetic thematic maps – maps that combine several indicators in variety of ways (show correlation between indicators, sum of indicators etc.) and visualize these synthetic measures
