Miscellaneous Functions for Southwest Fisheries Science Center

Collection of conversion, analytical, geodesic, mapping, and plotting functions. Used to support packages and code written by researchers at the Southwest Fisheries Science Center of the National Oceanic and Atmospheric Administration.

Description

swfscMisc is a collection of utility functions used at the Southwest Fisheries Science Center in La Jolla, CA. The package contains functions for geodesic calculations, commonly used mapping functions, plotting special symbols, interacting with DAS sighting data generated by the line-transect survey data entry program WinCruz, and miscellaneous analytical and conversion functions.
