dcw-gmt
- Ebuilds: 1, Testing: 1.1.4 Description:
The Digital Chart of the World (DCW) is a comprehensive 1:1,000,000
scale vector basemap of the world. The charts were designed to meet
the needs of pilots and air crews in medium-and low-altitude
en route navigation and to support military operational planning,
intelligence briefings, and other needs. DCW-GMT is an enhancement
to DCW in a few ways: (1) it contains more state boundaries,
and (2) the data have been reformatted to save space and are
distributed as a single deflated netCDF-4 file.

gshhg-gmt
- Ebuilds: 1, Testing: 2.3.7 Description:
GSHHS is a high-resolution shoreline data set amalgamated from two
databases in the public domain. The data have undergone extensive
processing and are free of internal inconsistencies such as erratic
points and crossing segments. The shorelines are constructed
entirely from hierarchically arranged closed polygons. The data can
be used to simplify data searches and data selections, or to study
the statistical characteristics of shorelines and land-masses.

gsw-c
- Ebuilds: 2, Testing: 9999 Description:
The Gibbs-SeaWater (GSW) Oceanographic Toolbox contains the TEOS-10 subroutines for evaluating
the thermodynamic properties of pure water (using IAPWS-09) and seawater (using IAPWS-08 for
the saline part). The GSW library does not provide properties of ice or moist air (these
properties can be found in the SIA library). This GSW Oceanographic Toolbox does not adhere
to strict basic-SI units but rather oceanographic units are adopted.
