Reader Overview

The AIS Reader module produces FME features for all AIS messages found in a text or log file which contains AIS messages stored as ASCII.

AIS messages are decoded and then translated into FME features. Each AIS message corresponds to a FME feature type. The information in each AIS message will appear as attributes on the corresponding FME feature type.
