Evaluation of the quality of auxiliary data

A SAS script was written for evaluation of the quality of auxiliary data (TACENQ and TACSAT). The script is applicable to each national data table and generates graphs of data availability (number of ships, trips) and of parameter ranges (haul duration, time of setting the net, fishing depth etc.).

Also maps of catch (by species) and effort distribution are generated. These graphs and maps can be used to make a quick inventory of the contents of the data table and of possible mistakes in the data. Another SAS script was written to compare the auxiliary data (TACENQ and TACSAT) with the existing data (EFLALO). This script produces graphs that can be used to get an idea of the overlap in both data tables (catch and effort by ship & trip, catch and effort by ICES rectangle etc.). Also maps of effort distribution in both data tables can be compared.
