Database files

Please download the database files here or create them using the builder.

To use the builder, first install shapelib, then:

cd database/builder
./makedb.sh

This will create database files in out and out_v1, as well as a db.zip containing both directories.

The files in the folder out_v1/ use a newer format and use less space to encode the same information.

The numbers in on the file names indicate the resolution. The *21 file has a higher resolution for storing the borders, but it is larger. The *16 file has a longitude resolution of 0.0055 degrees (~0.5km) and the *21 file has 0.00017 degrees (~20m)
