Questions & Answers
GTZ files: Frequently Asked Questions
What are GTZ files?
The .gtz file format is a compressed GPS data file format used by GPS TrackMaker software. It is a proprietary file format developed by GPS TrackMaker and is used to store GPS data such as waypoints, routes, and tracks. The .gtz file format essentially compresses GPS data into a smaller file size, making it easier to store and transfer over the internet. GPS TrackMaker software also allows users to generate .gtz files from GPS data in different formats, such as GPX or KML, for easy sharing with other GPS users who may not have the same GPS data file formats.
Can reaConverter open GTZ files?
reaConverter fully supports the GTZ file format – open, edit, and export GTZ files to any other popular file format with ease.
Do I need QGIS or ArcGIS to convert GTZ files?
No. reaConverter reads GTZ files on its own, so the conversion needs no GIS installation and no licence. It handles whole folders at once, which suits survey archives, tile sets and data deliveries that have to reach people working in other software.
