bcBathymetry

Bathymetry data spanning British Columbia's coast.

datasets

This software has evolved from fisheries research conducted at the
Pacific Biological Station (PBS) in 'Nanaimo', British Columbia, Canada. It
extends the R language to include two-dimensional plotting features similar
to those commonly available in a Geographic Information System (GIS).
Embedded C code speeds algorithms from computational geometry, such as
finding polygons that contain specified point events or converting between
longitude-latitude and Universal Transverse Mercator (UTM) coordinates.
Additionally, we include 'C++' code developed by Angus Johnson for the
'Clipper' library, data for a global shoreline, and other data sets in the
public domain. Under the user's R library directory '.libPaths()',
specifically in './PBSmapping/doc', a complete user's guide is offered and
should be consulted to use package functions effectively.

bcBathymetry function

Three-element list: <code>x</code> = vector of horizontal grid line
 locations, <code>y</code> = vector of vertical grid line locations, <code>z</code>
 = (<code>x</code> by <code>y</code>) matrix containing water depths measured in
 meters. Positive values indicate distance below sea level and
 negative values above it.
