POI Directory


I was in Paris not long ago and got into a cab which had a GPS unit. I told the driver where I wanted to go and he pulled out a directory, about 2 inches thick, looked up the hotel, punched in about 4 to 5 numbers and off we went. I figure it must be something like a telephone directory for use with a GPS device. Probably loaded with a POI file indexed to the numbers in the directory. The book must have had every business in Paris listed. Has anyone ever seen anything like this? Seems like it would take forever to write the POI file.
