The following module was proposed for inclusion in the Module List:
modid: Geo::GSHHS::PurePerl
DSLIP: bdpOp
description: Read vector coastline data
userid: OWHITE (Oliver White)
chapterid: 23 (Miscellaneous_Modules)
communities:
modules.cpan.org have discussed the name (for small values of
discuss...)
similar:
rationale:
The Global Self-consistent, Hierarchical, High-resolution Shoreline
Database (GSHHS) is a useful dataset which represents the coastlines
of the world, in 5 different resolutions, as a set of polygons. It's
very useful, not only for use as vector data, but because it can be
converted to an image of the world for prorgrams which handle images
(web-applications, for example).
The data is published by the University of Hawaii, and available as
a set of binary data files. I have a perl module which can read such
data, and thought it might be useful to publish that on CPAN for
others to use.
I'm suggesting the *::PurePerl namespace, so that if somebody
writes an implementation in C (which will likely be faster, hence
more useful), then I won't get in the way of any later modules.
I'm suggesting Geo::* rather than Geography::* because it seems to
be common among other modules such as Geo::Shapefile, although the
Geography::* namespace has started to appear recently
I'm suggesting Geo::* rather than GIS::* or Cartography::*, because
neither of those would show up in a search for "Geo" which might be
initiated by anyone looking for modules similar to Geo::ShapeFile
and Geo::GeoIP, Geo::OSGB, etc.
