Hello Victor,
finally I managed to do a systematic analysis og Germany_Niedersachsen.obf about doubled street names.
I used inspector.bat to generate an output with -address parameter and named the output as a CSV file.
Then import that csv file in LibreOffice to delete all unnecessary lines and columns.
Then load that csv file in Notepad++ to delete blank lines and separate cells with street names that only pure street names remain.
Have the name of the city filled in a new column so that really each row with a street name has also city name.
Have additional columns filled with street name if a street name is double.
Use AutoFilter to keep only rows with double street names.
Result for the mentioned obf file:
There are 11.275 (!!!) doubled streets!
And I assume that only very few are streets that are double within a city also in real world.
Should I open a bug ticket and append that file with the doubled streets? or send it by email (also to anyone interested) before to investigate whether my thoughts are wrong or not?
