I'm a little shocked at the small size of the POI files. I thought they would be heaps larger.

csv files are relatively small, as they don't have all the unnecessary formatting.

The CSV files are tiny as they are just flat text separated by comma's.

Its a great way of storing and sharing spreadsheet data without all the extra bulk that comes with applications such as Excel

It could be actually even smaller - I've recently found out about NAC (aka Universal Address) which store the geographical positions in the form of two strings of letters and digits (e.g. H5Q2R R48PF - Eiffel Tower). The brilliant thing about this geocoding system is that it is almost indefinitely scalable - the more precision you need, the more digits/letters you use as each character represents a fraction of the area described by the previous characters (i.e. H5Q2R is contained within H5Q2, which is contained in H5Q and so on.)

In a real-life situations you wouldn't need more than 10 characters (as 5+5 characters give you the precision of ~3 ft).
