GPS Correlate review
Precise GPX-to-photo correlation for technical users who want GUI and CLI control.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
GPS Correlate is an open-source desktop application that matches photo timestamps with locations from GPS tracks, then writes the resulting coordinates into image EXIF metadata. It is designed for solo users and small teams who want local control over photo geotagging, with both a graphical client and a command-line client. The workflow supports individual photos as well as batch correlation, making it suitable for technical photographers managing track-backed image collections.
The published feature set focuses on precise track synchronization. The graphical interface imports GPX files, including multiple files, and can interpolate locations between recorded GPS points. Time-zone and photo-time offset controls help align camera timestamps with track data. GPS Correlate can also write movement-heading and camera-direction tags, extending the metadata beyond latitude and longitude. Because the software is open source and deployed on the desktop, it fits users who prefer local processing rather than a hosted service or subscription workflow.
Its scope is intentionally narrow: GPX is the documented track-import format, and Windows and Linux are the supported platforms. Documentation is the listed support channel, so teams seeking broader service operations or a wider support model may prefer a different product. GPS Correlate is a strong choice for technically confident users who need interpolation, offset adjustment, command-line automation, and selective GPS-tag removal. It is less suited to buyers looking for cloud collaboration, mobile deployment, or a broader ecosystem of integrations.
GPS Correlate pros and cons

- Offers graphical and command-line clients plus heading tags and GPS removal
- Where it doesn't
- Desktop deployment limits use to local Windows or Linux workflows
- Track import is centered on GPX files
- Documentation is the listed support channel
