PBSmapping 2.66: user’s guide
software development, fisheries
This report describes a second version of software designed to facilitate the compilation and analysis of fishery data, particularly data referenced by spatial coordinates. Our research stems from experiences with information on Canada’s Pacific groundfish fisheries compiled at the Pacific Biological Station (PBS). Despite its origins in fishery data analysis, our software has broad applicability. The library PBSmapping extends the R-statistical 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. We also present a number of convenient utilities for Microsoft Windows operating systems that support computational geometry outside the framework of R. Our results, which depend significantly on the work of students, illustrate the convergence of goals between academic training and applied research.
