Caveats

While the data is very useful you should note the following:

  • Once a name is put into the database, it is never removed unless it is an obvious duplicate. This means that there are many, many names that have no modern significance.
  • The geographical resolution is often very coarse, from experience features can often be two to three kilometres from their actual locations.
  • Places where people live are are generally just classifies as "PPL", Populated Place. This can be anything from a city to what is now just a farm house.
  • There is a small but significant amount of entries that are inaccurate or plain wrong: mistranscriptions, places that are listed as in one country but actually somewhere else completely.
  • If you use not only the approved data, but also spelling variants and so on, you have often more than one node with the same coordinates, containing each of them another spelling variant.
