Building DCW-GMT

The original data in ASCII format are stored in the orig directory.

To build the dcw-gmt.nc file from the DCW data, you need to first edit the configuration file config.mk, then run:

make build-dcw		# Make the dcw-gmt.nc netCDF file
make archive		# Create tarball and zipfile of DCW for GMT distribution
make checksum		# Compute MD5 checksum for the tarball

When done, clean out the directory with make spotless.

To add new countries:

  1. obtain ascii data
  2. determine ISO 2-char country code XX and name file XX.txt
  3. determine which continent ZZ it belongs to and place in ZZ directory
  4. add new entry in dcw-countries.txt in alphabetical position on XX

To add new state boundaries

  2. determine ISO 2-char country code XX and state code YY and name file YY.txt
  3. determine which continent ZZ it belongs to and place in ZZ/YY directory

To remove countries or states:
