This document provides a user guide for the AIS TrackBuilder Tool v1.0, which is designed to take AIS point data from an Esri FileGeodatabase and convert it to a polyline track line feature class. The user specifies the input AIS point feature class and the output track line feature class name and location, and selects options on how the track lines are segmented. The tool is designed to work with AIS point data created with the CSV to filegeodatabase Tool, but is flexible and can work with any point dataset format as long as it includes a ID field to distinguish unique track lines and a datetime field.
