GPX Editor
GPX Editor is a macOS utility from Modesitt Software for opening, viewing, editing, and saving GPX map and GPS track files.
What is GPX Editor?
GPX Editor is a Mac application published by Modesitt Software for working with GPX files created by GPS devices, mapping tools, and route-planning apps. It is designed for users who need to inspect and modify waypoints, routes, tracks, and track points rather than only viewing them. The app presents GPX data on a map and in editable lists, making it useful for cleaning up recorded tracks, adjusting route points, combining data, or preparing files for export to other devices and services. Available documentation and product materials indicate support for map viewing, elevation-related tools, spreadsheet-style copy and export workflows, and drag-and-drop editing of locations and track point order. Mac users are most likely to encounter it as a specialized utility for hiking, cycling, travel, or GPS workflow tasks. It is not a core macOS component and is generally only needed if you actively use GPX-based mapping or navigation files.

Safety overview
Status: Mostly safe
This appears to be a legitimate third-party Mac app for editing GPX files, not a built-in macOS component. It may contain important route, waypoint, or track data if you use GPS workflows, so the main risk is losing or altering saved navigation files rather than harming the system.
Recommendation: Keep it if you edit or manage GPX files on your Mac. If you do not use GPX-based mapping or GPS data, it is usually optional and can be removed like other user-installed apps.
