Our intension is to put x,y-coordinates on the addresses, where people are staying during day- and nighttime and these coordinates should be as

geographical correct as possible

How to place these people(1)

The CPR (Central Person Register) tells us the adress, but where do we get information about the geographical position?

A good place to start could be in the Danish “Public Information Server” (OIS)
