The starting point was data published officially by the Police, followed by a more specific database, which I requested from the Police. We will look at the first attempt to visualize the data, which failed spectacularly. On this example I will demonstrate the importance and necessity of analysis before data requests and project launching. I will also show how the second version of the map was created in cooperation with the Czech Statistical Office. Finally, demonstration of final data refining and its visualization will be shown. The map itself should be more accurate than the current map of crime compiled by the Police (the project is still running, final version should be ready by the end of August).enhttp://purl.org/coar/access_right/c_abf2Pražská mapa kriminalityotevřená dataČeská republikaPrahaBigCleanPrague Crime MapOpen DataCzech RepublicPragueBigCleanconference paperteorie datkriminalitavizualizacedata theorycriminalityvisualizationhttp://psh.ntkcz.cz/skos/PSH6590http://psh.ntkcz.cz/skos/PSH9727http://psh.ntkcz.cz/skos/PSH12568
