AbstractNew GPS Technique to Update GIS Track: Database Design, Automation, and Management Author(s): Richard Lewis A new GPS data maintenance technique allows GIS users to easily update, verify, and modify features and collect previously unrecorded features. Data maintenance will allow the user to transfer GIS files into GPS data loggers for background reference, updating, and navigation purposes. The data maintenance cycle starts by moving previously collected themes into the GPS field system, performing updates, and moving the field data back to GIS as a newly updated theme. Features may be added, modified, deleted, and restructured. Features can be filtered in the field to concentrate on feature type, attribute value, time collected, and update status.
