Map Data Workflow

Turn GIS data into something anyone can open

A map saved as JP2 opens on any computer and any phone. reaConverter produces those from GTZ in batch, entirely offline.

  • Render every file in a folder to JP2 with the same size and settings
  • Set DPI and output dimensions before the run, not afterwards
  • Pick up new data automatically with Watch Folders, or script the job from the command line

Everything runs on your PC, which matters for cadastral, utility and client data that should not pass through an upload form.

Security was our top concern when evaluating file conversion tools. reaConverter’s offline mode and role-based access controls let us lock it down for sensitive environments. No unexpected network calls or bloat — just clean, fast conversions. Even passed our pen-testing scans without a hitch.

FAQ

GTZ to JP2 Conversion

What are GTZ files?

GTZ files contain data connected to maps and routes created via GPS TrackMaker, a real-time navigation program developed by Geo Studio Technologies Ltd. The software allows you to locate where you are on a map, to create a vector-based map, to create and edit tracklogs, stopping points and routes. GTZ files include features that are similar to GTM files.

What are JP2 files?

JP2 or JPEG 2000 is an improved version of JPEG, one of the most popular file formats for storing and transferring images.

JP2s are created using the JPEG2000 Core Coding application, but can also be obtained through conversion from other formats.
